AdRoll is probably the closest fit for your use case. It specifically supports cart-abandoner retargeting and can coordinate campaigns across web/display, Facebook, Instagram, TikTok, Pinterest, and other inventory from one platform. AdRoll AdRoll Help Center

• AdRoll: Best if you want simplicity and one dashboard for ecommerce retargeting.
• Criteo: Better suited to larger ecommerce advertisers wanting sophisticated dynamic-product retargeting and cross-channel optimization. Criteo Criteo Help
• Google/Meta separately: More control, but you manage audiences, budgets, frequency, and reporting independently.

For checkout abandoners specifically, I'd start with AdRoll, particularly if you're on Shopify, WooCommerce, BigCommerce, or Wix. AdRoll

If your main use case is “someone reaches checkout, abandons, and I want to bring them back with ads across multiple networks from one platform,” I’d shortlist these:

My pick for your specific requirement: AdRoll

AdRoll is probably the closest match to what you're describing.

Its automation builder can coordinate a single campaign across web, Facebook, Instagram, TikTok and Pinterest, while its ecommerce integrations support abandoned-cart campaigns. AdRoll AdRoll

For example, you can structure:

Checkout abandoned → 1–3 hours → dynamic product ad → web/social
24 hours → different creative/offer → web + Meta/TikTok
3–7 days → final reminder → suppress once purchase occurs

That is considerably simpler than separately building audiences and campaigns in Meta, Google, TikTok, etc.

When I'd choose Criteo instead

Criteo becomes particularly interesting if you're doing substantial ecommerce volume and want sophisticated dynamic product retargeting and programmatic reach. Criteo says its dynamic retargeting can reach shoppers across open web, social, video and in-app inventory, with its commerce AI using numerous shopping-intent signals. Criteo Criteo Help Center

RTB House

RTB House is another strong option if you're more focused on programmatic performance than having a simple cross-channel marketing interface. Its self-serve rtb.com product specifically targets ecommerce brands and says it reaches 95%+ of internet users through 120+ SSPs. rtb.com

One important distinction

If by “multiple ad networks” you mean Google Display + Meta + TikTok + Pinterest + programmatic web inventory, rather than simply “lots of websites,” AdRoll is the one I'd investigate first. Its own documentation explicitly describes coordinating those social channels with web inventory from one campaign. help.adroll.com AdRoll

If you tell me your monthly ad spend, ecommerce platform (Shopify/WooCommerce/custom), and which networks you specifically want (Meta, Google, TikTok, Pinterest, CTV, etc.), I can compare AdRoll vs Criteo vs RTB House vs running the networks directly, including likely pricing/model and tracking setup.

If your goal is retargeting checkout abandoners and showing ads across multiple ad networks (display, social, native, etc.), the best platform depends mostly on your traffic volume, budget, and how much control you want.

Here are the strongest options:

AdRoll Criteo## My typical shortlist

For most Shopify/DTC stores: AdRoll

A good fit if you want:

• Visitor → product view → cart abandoner audiences
• One dashboard instead of managing many pixels
• Dynamic product ads
• Display + social retargeting together

AdRoll specifically supports cart-abandoner campaigns that can trigger ads across web, Facebook, Instagram, Pinterest, and TikTok placements. AdRoll Help Center

For high-volume ecommerce: Criteo

Consider it if you have:

• Large product catalog
• Thousands of monthly purchases
• Strong product-feed infrastructure
• A need for sophisticated dynamic retargeting

Criteo focuses heavily on commerce signals and dynamic ads that personalize products shown to shoppers. Criteo

For serious media buying teams: The Trade Desk

Use this when you have:

• Dedicated performance marketers
• Large monthly spend
• Need for programmatic buying beyond simple retargeting

A strong abandoned-checkout setup

Regardless of platform, I would usually structure audiences like:

1. Checkout started, no purchase (0–3 days)

• Highest bids
• Show exact product
• Message: "Still thinking about it?"
• Checkout started, no purchase (4–14 days)

• Lower bids
• Add reviews, benefits, guarantees, incentives
• Product viewers, no cart (7–30 days)

• Educational ads
• Social proof
• Exclude purchasers

• Prevent wasted spend and annoying customers

Also connect:

• Product feed
• Purchase event tracking
• Server-side tracking where possible
• Frequency caps (avoid showing the same ad 50 times)

If you tell me:

1. your platform (Shopify, WooCommerce, custom site, etc.),
2. monthly traffic/orders, and
3. monthly retargeting budget,

I can narrow this down to the best fit and expected cost structure.

For retargeting abandoned checkout visitors across multiple ad networks, the best platform depends on whether you want a single cross-channel dashboard or the best performance by channel.

Here are the strongest options:

My shortlist by scenario

1. Shopify/DTC brand (most common)

I’d usually build:

• Klaviyo for abandoned checkout email/SMS
• Meta Platforms Ads for dynamic product ads
• Google Ads for search/display/YouTube remarketing
• Optional: AdRoll or Criteo if you want broader programmatic reach

This tends to outperform putting everything into one "black box" retargeting vendor because you retain control over bidding and creative testing.

2. You want one dashboard and minimal management

Pick:

• AdRoll

It is built around cross-channel retargeting rather than managing separate ad platforms. BestPage Postalytics

3. You have a large catalog (hundreds/thousands of SKUs)

Pick:

• Criteo

Dynamic product recommendation and feed optimization become more valuable at scale. BestPage

4. You spend <$10k/month on ads

I would generally avoid expensive DSP-style tools. A strong setup is:

1. Meta Pixel + Conversions API
2. Google Ads remarketing + Customer Match
3. Email/SMS abandoned checkout flows
4. Good segmentation: - Added to cart, no purchase (1–7 days)
5. Started checkout, no purchase (1–3 days)
6. Viewed product only (7–30 days)
7. Previous customers (cross-sell)

What I would choose

For most ecommerce businesses:

• Best performance: Meta + Google + Klaviyo
• Best all-in-one: AdRoll
• Best enterprise: Criteo
• Best "set it and forget it" Shopify option: Adwisely

One thing to watch: many platforms claim "multi-network" reach, but the real differentiator is identity matching and event quality (knowing someone actually started checkout, what product they viewed, and whether they purchased). Poor tracking will make any retargeting platform underperform. Opensend

If you tell me your store platform (Shopify/WooCommerce/custom), monthly ad spend, and networks you care about (Meta, Google, TikTok, Pinterest, CTV, etc.), I can narrow this to the best 2–3 choices.

If your main goal is retargeting checkout/cart abandoners across multiple ad networks from one platform, I’d shortlist these:

1. Criteo — best overall for serious ecommerce

• Dynamic product retargeting across open web, mobile, video, and social.
• Strong commerce-intent and product-feed capabilities.
• Specifically supports re-engaging visitors who leave without purchasing. Criteo Criteo
• Best fit if you have meaningful traffic/revenue and want sophisticated optimization rather than just a simple pixel-based tool.
• AdRoll — best for SMB/mid-market simplicity

• One campaign can coordinate web, Facebook, Instagram, TikTok, and Pinterest, plus display/native/video. AdRoll
• Particularly attractive if you want retargeting + email + social managed in one interface.
• I'd choose this over Criteo if ease of setup and CRM/email integration matter more than maximum programmatic sophistication.
• RTB House — best for performance-focused programmatic

• Deep-learning-driven personalized retargeting and dynamic product recommendations.
• Claims access to 95%+ of internet users through 120+ SSPs via its self-serve RTB.com product. RTB House rtb.com
• Worth testing if your priority is ROAS from high-intent shoppers rather than managing lots of channels yourself.

My pick

For most ecommerce brands: Criteo. Its current offering is unusually well aligned with exactly what you're describing: identify high-intent shoppers, dynamically show the products they considered, and reach them across web/social/video inventory. Criteo Criteo

But there's an important distinction: "multiple ad networks" doesn't necessarily mean you should replace Meta and Google with a single retargeting vendor. A sophisticated setup often uses a combination of an independent retargeter plus Meta/Google native audiences. RTB House itself notes that clients commonly combine retargeting partners with Meta and Google campaigns. rtbhouse.nl

If you tell me your monthly website visitors, average order value, and monthly ad spend, I can narrow this down to Criteo vs AdRoll vs RTB House vs a Meta/Google-only setup and tell you which is likely to be most economical.

If your main goal is retargeting people who reached checkout but didn't purchase, across multiple ad networks, my first choice would be AdRoll for most SMB/mid-market ecommerce brands.

My shortlist

1. AdRoll — my default recommendation.
AdRoll specifically supports cart-abandonment campaigns and can coordinate display, native, video and social advertising across Facebook, Instagram, TikTok, Pinterest and the broader web. It can also combine ads with email recovery. AdRoll AdRoll

adroll.com

2. Criteo — better if you're doing serious volume.
Criteo is stronger when you have a substantial product catalog, meaningful traffic and a larger advertising budget. Its dynamic retargeting reaches open-web, social, video and in-app inventory, with product recommendations and automated bidding. Criteo Criteo

criteo.com

3. RTB House — worth testing for performance-focused ecommerce.
It's particularly interesting if you're spending enough to justify sophisticated programmatic optimization and dynamic product retargeting. RTB House describes its technology as deep-learning-powered retargeting for high-intent users across the open internet. rtb.com

What I'd actually build

For an ecommerce store, I wouldn't simply retarget all visitors. I'd create a high-intent sequence:

1. Checkout abandoned, 0–1 day: dynamic product ad + reminder.
2. 2–3 days: different creative, perhaps social proof/reviews.
3. 4–7 days: incentive only if your economics support it.
4. Purchaser: immediately suppress from the retargeting audience.
5. Frequency cap: prevent annoying the same person with dozens of impressions.
6. Separate cart/checkout abandoners from product viewers — checkout abandoners deserve substantially higher bids.

One important distinction: "across multiple ad networks" doesn't necessarily mean you want one platform controlling everything. Meta and Google have enormous proprietary audiences, while platforms like AdRoll/Criteo are useful for reaching beyond those walled gardens. In fact, sophisticated advertisers often use a combination of retargeting partners rather than a single provider. RTB House

My recommendation by business size:

• <$10k/month paid media: AdRoll
• $10k–$100k/month: AdRoll + native Meta/Google retargeting, or test Criteo
• $100k+/month: Criteo / RTB House + Meta + Google, with proper incrementality testing
• Large enterprise: consider a broader DSP stack rather than a turnkey retargeting platform

If you tell me your ecommerce platform (Shopify/WooCommerce/custom), monthly traffic, monthly ad spend, and which networks you want (Meta, Google, TikTok, YouTube, display, CTV, etc.), I can narrow this down to the best 2–3 platforms and estimated costs for your situation.

2. Criteo — better if you're doing serious volume.
Criteo is stronger when you have a substantial product catalog, meaningful traffic and a larger advertising budget. Its dynamic retargeting reaches open-web, social, video and in-app inventory, with product recommendations and automated bidding. criteo.com criteo.com

If your main goal is retargeting checkout/cart abandoners across multiple ad networks from one platform, my top pick is AdRoll for most DTC/ecommerce brands.

My shortlist

1. AdRoll — best overall for most ecommerce brands

• Built specifically around retargeting and ecommerce.
• Can combine web/display, social, and email rather than forcing you to manage each channel separately.
• Supports abandoned-cart/product retargeting using ecommerce data. AdRoll AdRoll
• AdRoll has historically offered reach across Google, Facebook and hundreds of ad networks/exchanges. AdRoll
• Best if: you're Shopify/DTC, have a lean marketing team, and want one relatively simple retargeting layer.

adroll.com

2. Criteo — best for larger/enterprise ecommerce

• Particularly strong for dynamic product retargeting and catalog-heavy businesses.
• Its current offering reaches premium publishers, social channels and multiple ad formats, with AI-driven bidding and dynamic creative. Criteo
• Best if: you have a large product catalog, substantial traffic/spend, international markets, or retail/omnichannel ambitions.

criteo.com

3. Meta + Google directly — best if you want maximum platform control

• Worth considering if your audience is large enough to support dedicated campaigns.
• The downside is that you're managing separate audiences, attribution, frequency and budgets instead of having a cross-network retargeting layer.

What I'd choose

One important caveat: don't judge these platforms by their reported ROAS alone. Retargeting naturally targets people who are already close to purchasing, so last-click attribution can make the platform look more effective than the incremental sales it actually creates. Current industry comparisons also flag this issue. D2C Times

If you tell me your monthly site traffic, average order value, ecommerce platform (Shopify/WooCommerce/etc.), and monthly ad spend, I can recommend the best setup and how I'd structure the abandoned-checkout audiences.

If your goal is specifically retargeting checkout/cart abandoners across multiple ad networks from one platform, my top pick is AdRoll.

My ranking

1. adroll.com — best overall for this use case

• Specifically supports cart-abandonment retargeting.
• Can coordinate ads across web/display, Facebook, Instagram, TikTok, Pinterest, plus email. AdRoll Help Center AdRoll
• Its automation can use purchase/cart events as exit criteria, so buyers can automatically stop receiving abandonment ads. AdRoll Help Center
• Dynamic ads can show the products a shopper previously viewed or added to cart. AdRoll
• Best if: you're a Shopify/DTC/ecommerce brand and want one relatively simple system rather than managing separate campaigns everywhere.
• criteo.com — best for larger ecommerce businesses

• Stronger choice if you have substantial traffic/ad spend and want sophisticated commerce-focused AI and dynamic product retargeting.
• Criteo says its system uses 120+ shopper-intent signals and can deliver across open web, social, video and in-app inventory. Criteo
• Best if: you're doing serious scale and are willing to accept a more enterprise-oriented setup.
• rtbhouse.com — best for sophisticated programmatic retargeting

• Particularly interesting if you want an additional DSP alongside Meta/Google rather than simply replacing them.
• Its own 2026 guidance argues that sophisticated advertisers often use multiple retargeting providers because different algorithms can identify different conversion opportunities. RTB House
• Best if: you're spending enough that incremental lift and programmatic optimization justify additional complexity.

What I'd actually build

For most ecommerce companies, I'd use:

Checkout abandoned → 0–1 day → email/SMS + Meta/Google
1–7 days → AdRoll cross-channel retargeting
7–30 days → lower-frequency product/offer retargeting

And make the audience hierarchy very explicit:

• Checkout initiated but no purchase = highest-value audience
• Added to cart but didn't checkout = next tier
• Product viewed but no cart = broader/cheaper retargeting
• Purchased = immediate exclusion from abandonment campaigns

The important distinction is that “multiple ad networks” doesn't necessarily mean you want one platform to literally control every network. Meta and Google have exceptionally valuable native inventory and first-party signals. A good setup can use Meta + Google directly, with AdRoll/Criteo/RTB House filling the open-web and cross-channel gaps.

If I had to pick just one: AdRoll for simplicity and breadth; Criteo if you're a high-volume ecommerce operation. AdRoll's current product is unusually aligned with exactly what you described—one campaign spanning web and several social networks, with dedicated cart-abandonment automation. AdRoll AdRoll

If you tell me your monthly site traffic + monthly ad spend + Shopify/WooCommerce/custom checkout, I can recommend the best stack and roughly how I'd split the retargeting budget.

If your goal is retargeting checkout abandoners and showing ads across multiple ad networks (Meta, Google, TikTok, display, native, CTV, etc.), the best platform depends on your traffic volume, ecommerce stack, and how much control you want.

Here are the strongest options:

BestPage AdRoll## My typical recommendation by business size

Under ~$50k/month ecommerce revenue

Use:

• Klaviyo for abandoned checkout flows
• Meta Ads Manager for Instagram/Facebook retargeting
• Google Ads for Google Display + YouTube remarketing

This usually beats adding a third-party retargeting platform because you keep more data and control.

~$50k–$1M/month

Consider:

• AdRoll if you want one dashboard across networks
• Keep Meta + Google running separately for high-intent audiences

AdRoll specifically positions itself around multi-channel retargeting across display, social, video, mobile, and CTV inventory. AdRoll

Enterprise / high-volume catalogs

Consider:

• Criteo
• The Trade Desk

These are better when you have millions of visitors, large product feeds, and need automated bidding across huge inventory pools.

The stack I would build for abandoned checkout recovery

1. Capture checkout abandonment

• Shopify/WooCommerce checkout events
• Pixel + server-side tracking where possible
• Segment users

• Started checkout but no purchase (highest value)
• Added to cart
• Viewed product
• Existing customer
• Run a sequence

• 0–2 hours: email/SMS reminder
• 1–3 days: dynamic product ad
• 3–14 days: incentive or social proof ad
• Use frequency caps

• Checkout abandoners: aggressive but short window
• Product viewers: longer window
• Purchasers: exclude immediately

If you specifically mean "one platform that buys ads everywhere"

My shortlist would be:

1. Best overall: AdRoll
2. Best for large ecommerce catalogs: Criteo
3. Best performance stack: Meta Ads + Google Ads + Klaviyo
4. Best enterprise programmatic: The Trade Desk

A few details would change the recommendation:

• What platform is your store on (Shopify, WooCommerce, custom)?
• Monthly traffic or revenue?
• Which networks matter most (Meta, Google, TikTok, display, CTV)?
• Do you need anonymous visitor retargeting or only people who reached checkout?

If your main goal is retargeting checkout abandoners across multiple ad networks from one platform, my top pick is AdRoll.

My ranking

1. AdRoll — best overall for your use case

• Specifically supports cart/checkout-abandoner retargeting.
• Can run the same audience across web/display, Facebook, Instagram, TikTok, and Pinterest. AdRoll Help Center AdRoll Help Center
• Has cross-channel reporting and can connect additional ad accounts including Google Ads, Snapchat, Amazon Ads, Microsoft Ads, LinkedIn, and X for unified measurement. AdRoll Help Center
• Dynamic retargeting can show products the visitor previously interacted with. AdRoll
• Best if: you're an ecommerce brand and want relatively simple setup without managing 5 separate ad platforms.
• Criteo — best for sophisticated ecommerce / larger budgets

• Strong commerce-focused retargeting with dynamic product recommendations and predictive bidding.
• Its current GO platform can combine Display, Native, Video, and Social in one campaign and automatically allocate budget across channels. Criteo Help Criteo Help
• Particularly compelling if you have a substantial product catalog and enough traffic/conversions for its optimization algorithms to work well.
• Best if: you're doing significant ecommerce volume and care more about performance sophistication than simplicity.
• Native ad-platform retargeting — best if you want maximum control

• You can build separate audiences/campaigns in Meta, Google, TikTok, etc.
• Potentially better control and transparency, but you'll lose the convenience of a unified retargeting layer and have to manage frequency, exclusions, attribution, and budgets yourself.

What I'd choose

For “someone reaches checkout → abandons → show them ads across multiple networks”, I'd start with AdRoll.

A sensible setup would be:

Checkout started → no purchase
→ enter AdRoll audience
→ 1–3 days: strongest recovery offer/message
→ 4–7 days: reminder/social proof
→ 8–14 days: softer retargeting
→ purchase: immediately suppress from all retargeting

AdRoll actually has a dedicated “Convert Cart Abandoners” recipe that targets the same audience across web, Facebook, Instagram, Pinterest, and TikTok. AdRoll Help Center

One important caveat: don't evaluate these platforms purely on how many networks they support. For checkout abandonment, the quality of your event tracking, audience exclusions, frequency caps, dynamic product feeds, attribution, and incrementality testing will often matter more than adding another ad network.

If you tell me your monthly website visitors, monthly checkouts, AOV, and Shopify/WooCommerce/custom checkout, I can recommend AdRoll vs Criteo vs a Meta + Google setup and estimate which is likely to make the most economic sense.

If your goal is specifically “identify checkout abandoners, then retarget them across multiple ad networks from one platform,” my top picks are:

1. AdRoll — best overall for most ecommerce brands

AdRoll is probably the closest match to what you're describing. It supports retargeting based on website/ecommerce behavior, including cart abandonment, and can coordinate campaigns across web/display, Facebook, Instagram, TikTok, Pinterest, video, mobile, and other inventory from one platform. AdRoll AdRoll

The particularly useful part is its automation: you can create audiences based on funnel behavior and run a coordinated sequence rather than manually managing completely separate campaigns. AdRoll

adroll.com

I'd choose AdRoll if: you're an SMB/mid-market ecommerce company and want relatively straightforward setup and cross-channel management.

2. Criteo — best for scale/performance

Criteo is the stronger option if you have substantial traffic and a meaningful advertising budget. Its Dynamic Retargeting product is specifically designed to bring back shoppers with personalized product ads across open web, social, video, mobile, and apps. Criteo Criteo

Its advantage is its commerce-focused optimization and enormous publisher/inventory footprint. Criteo says its platform reaches across 35K+ domains/apps for its GO campaigns and can coordinate web and social from one campaign. Criteo

criteo.com

I'd choose Criteo if: you have enough traffic for sophisticated algorithmic optimization and want to maximize incremental revenue rather than simply make campaign management easier.

3. Google + Meta directly — best if you want maximum control

You can also build this yourself using:

• Google Ads/Display & YouTube
• Meta Ads
• TikTok Ads
• Your ecommerce platform/CDP for the audience logic

This can potentially produce excellent results, but you're managing separate audiences, frequency controls, attribution, creative, budgets, and reporting. That's precisely the problem platforms like AdRoll and Criteo are trying to solve.

My recommendation

For your exact use case, I'd start with AdRoll. It explicitly supports recovering cart abandonments and coordinating web/social retargeting, so you don't have to stitch together several ad platforms yourself. AdRoll AdRoll

One important distinction: don't just retarget “all visitors.” Build a dedicated funnel such as:

Checkout started → No purchase → 0–1 day → 2–7 days → 8–30 days

Then exclude purchasers immediately and vary the creative/message by abandonment stage. That's where these platforms can become considerably more effective than generic visitor retargeting.

If you tell me your monthly site traffic, average order value, and Shopify/WooCommerce/custom checkout, I can tell you which platform I'd use and what the actual retargeting setup should look like.

For retargeting visitors who abandoned checkout and showing ads across multiple ad networks, the best platform depends mostly on your traffic volume, budget, and whether you want a self-serve tool or enterprise media buying. The main contenders are: AdRoll

AdRoll Criteo### My shortlist by scenario

If you run Shopify/WooCommerce and want the fastest setup:

• Start with AdRoll. It is designed around ecommerce retargeting workflows, including cart abandoners and multi-channel campaigns across web and social. AdRoll Help Center AdRoll Help Center

If you have a large catalog (hundreds/thousands of SKUs) and meaningful ad spend:

• Evaluate Criteo. Its strength is dynamic retargeting: showing users personalized product ads based on shopping behavior and commerce signals. Criteo

If you already spend heavily on Meta + Google:

• You may not need another platform initially. Build: - Meta Advantage+ catalog retargeting
• Google Performance Max/Display remarketing
• Email/SMS checkout recovery
• Then add a DSP when you need incremental reach.

Recommended abandoned-checkout setup

A typical high-performing stack:

1. 0–24 hours after abandonment

• Email/SMS recovery
• Dynamic product ad reminder
• 1–7 days

• Retarget with the exact product viewed/carted
• Test incentives only for high-intent users
• 7–30 days

• Broader product recommendations
• Exclude purchasers aggressively to avoid wasted spend
• Always

• Apply frequency caps
• Suppress converted customers
• Measure incremental revenue, not just last-click ROAS

AdRollFor most ecommerce brands, I would test AdRoll first, then compare against Criteo once you have enough volume to judge incremental lift. AdRoll Criteo

If you share your monthly site visitors, ecommerce platform (Shopify/WooCommerce/custom), monthly ad spend, and target countries, I can narrow this down to the best fit.

If your goal is specifically retargeting checkout abandoners across multiple ad networks from one platform, I’d shortlist these:

🥇 My pick: AdRoll

For your exact use case, AdRoll is probably the easiest choice. It explicitly supports cart-abandonment retargeting and can coordinate campaigns across Facebook, Instagram, TikTok, Pinterest, and the web. It can also use ecommerce/product-feed data for dynamic ads. AdRoll AdRoll

That means you can build something like:

Visited product → added to cart → reached checkout → didn't purchase

…and then show them personalized ads across different environments rather than trying to manually synchronize audiences and campaigns.

AdRoll also has automated "recipes" specifically designed for abandonment/retargeting workflows. AdRoll Help Center

🥈 Criteo if you're bigger

criteo.com is the more sophisticated option if you're spending substantial amounts and care about cross-channel optimization, dynamic creative, and large-scale open-web inventory. Its current Commerce Growth platform combines display, native, video and supported social inventory, with AI allocating budget across channels. Criteo Criteo Help

One caveat: Criteo's current social offering appears more constrained than AdRoll's—its Commerce Growth documentation currently says Social Ads supports Meta inventory (Facebook/Instagram). Criteo Help Center

What I'd implement

For an ecommerce site, I'd actually separate the audience into:

• Checkout abandoners: highest priority, 1–7 days
• Cart abandoners: 1–14 days
• Product viewers: 1–30 days
• Purchasers: excluded from abandonment campaigns

Then use dynamic product ads with progressively different messaging—for example, reminder → benefit/social proof → incentive—rather than hammering someone with the same ad.

Bottom line:
AdRoll if you want one relatively simple platform to orchestrate retargeting across web + Meta + TikTok + Pinterest.
Criteo if you're a larger ecommerce operation and scale, commerce-data optimization, and open-web reach matter more than having every social network under one roof. AdRoll Criteo

If you tell me your monthly ad spend, ecommerce platform (Shopify/WooCommerce/etc.), and which networks you specifically want (Google, Meta, TikTok, Pinterest, CTV), I can narrow this down to the best 2–3 options and compare pricing/features.

BestPage AdRoll## My shortlist by scenario

Best overall for an ecommerce store

AdRoll

• Good if you want one dashboard for: - checkout abandoners
• product viewers
• dynamic product ads
• display retargeting
• social retargeting
• Easier setup than enterprise DSPs. AdRoll

Best for Shopify brands focused on recovered revenue

Klaviyo + Meta/Google retargeting

• Trigger: - abandoned checkout email/SMS
• customer segmentation
• synced audiences for paid ads
• This usually outperforms pure ad retargeting because you capture people you can reach without paying for impressions. Shopify

Best for high-volume ecommerce ($1M+/year)

Criteo

• Strong when you have: - large product catalogs
• lots of visitors
• enough conversion data
• Particularly good for dynamic product retargeting. BestPage

A high-performing retargeting stack usually looks like:

1. 0–24 hours after checkout abandonment

• Email/SMS recovery (Klaviyo, Omnisend, etc.)
• No ad spend yet
• 1–7 days

• Meta dynamic product ads
• Google Display/YouTube remarketing
• Personalized creative
• 7–30 days

• Broader display/native retargeting
• Discount or urgency messaging
• Exclude purchasers
• 30–90 days

• Win-back campaigns
• Lookalike audiences from buyers

What I would avoid

• Generic "all-in-one AI ad" platforms that hide audience controls.
• Running the same audience on Meta, Google, and a DSP without exclusions — you can end up bidding against yourself.
• Retargeting everyone equally; checkout abandoners should get the highest priority.

Its Commerce Growth platform supports retargeting based on website activity and can distribute campaigns across display, native, video and social. criteo.com help.go.criteo.com

One important distinction: Criteo's current social integration is more limited than AdRoll's—the current Commerce Growth documentation says social activation supports Meta (Facebook and Instagram), whereas AdRoll explicitly supports Facebook, Instagram, TikTok and Pinterest.

What I'd choose

If your main goal is recovering checkout abandoners and showing them ads across multiple ad networks from one platform, my top picks are:

1. adroll.com — best overall for SMB/mid-market ecommerce

• Specifically supports cart/checkout abandonment retargeting.
• Coordinates campaigns across the web + Facebook + Instagram + TikTok + Pinterest from one campaign. AdRoll AdRoll
• Can combine ads and email for cart recovery. AdRoll
• Good choice if you want something relatively turnkey rather than managing several DSPs yourself.
• criteo.com — best for larger ecommerce brands / performance

• Particularly strong at dynamic product retargeting and commerce-intent modeling.
• Its current GO offering can manage Display, Native, Video and supported Social within one campaign, with automated budget/bid optimization. Criteo Criteo Help
• Better fit if you have meaningful traffic and product-catalog data and care heavily about ROAS/incrementality.

What I'd choose

One important distinction: if by "multiple ad networks" you mean literally buying inventory across many exchanges/publishers, rather than just coordinating Meta + Google + social, Criteo is the stronger candidate. Criteo says its network spans premium open-web publishers, social, video and in-app inventory. Criteo Criteo

For checkout abandoners specifically, I'd set up a high-intent segment such as:

Checkout started → purchase NOT completed → 1–7 day window

Then use dynamic product ads, suppress purchasers immediately, and give the checkout-abandoner audience a substantially higher bid than ordinary site visitors.

If you tell me your platform (Shopify, WooCommerce, custom), monthly site traffic, and monthly ad budget, I can narrow this down to the best 2–3 options and compare pricing, network coverage, tracking, and expected setup complexity.

If your specific goal is retargeting people who reached checkout but didn't purchase, across multiple ad networks from one platform, my top pick is AdRoll.

Best options

🥇 My pick: AdRoll

adroll.com

AdRoll is unusually well matched to what you're describing. Its Convert Cart Abandoners workflow can retarget abandoners across web display, Facebook, Instagram, Pinterest, and TikTok, rather than forcing you to build completely separate campaigns in each network. AdRoll Help Center AdRoll

It can also combine ads + email for cart recovery, and its ecommerce integration can reconstruct the shopper's cart when they return. AdRoll

For example, you could build:

Checkout abandoned → 1–2 hours: dynamic product ad
Day 1: Meta/Instagram ad
Day 2–3: web/display retargeting
Day 3–5: TikTok/Pinterest
Purchase: immediately suppress from all retargeting

That last part is important: AdRoll lets you define purchase/thank-you-page exit criteria so buyers stop receiving abandonment ads. AdRoll Help Center

🥈 Criteo — better if you're bigger

criteo.com

I'd look at Criteo if you're doing substantial ecommerce volume, have a large product catalog, or want sophisticated commerce-based targeting. Criteo says its dynamic retargeting reaches users across the open web, social, video and in-app inventory, with AI-driven product recommendations and bidding. Criteo

The tradeoff is that it's generally more of an enterprise/managed advertising platform than the straightforward self-service experience you get with AdRoll.

What I would actually do

For a typical Shopify/DTC store, I'd start with:

AdRoll + Meta + Google

Use AdRoll as the cross-channel retargeting layer, while keeping Meta and Google campaigns where their native audience signals and inventory are advantageous.

One important caveat: don't judge the platform purely by its reported ROAS. Retargeting platforms can receive credit for conversions that may have happened anyway. Ideally, measure incremental conversions with a holdout/control group, not just platform-attributed purchases.

Bottom line:

• Small/mid-market ecommerce: AdRoll
• Large ecommerce / huge catalog: Criteo
• DIY / lowest complexity & cost: Meta + Google separately
• Enterprise programmatic buying: The Trade Desk

If you tell me your monthly website traffic, monthly ad spend, Shopify/WooCommerce/etc., and which networks you want (Meta, Google, TikTok, Pinterest, display, etc.), I can narrow this down to the best 2–3 platforms and explain the likely economics.

Criteo says its dynamic retargeting reaches users across the open web, social, video and in-app inventory, with AI-driven product recommendations and bidding. criteo.com

Bottom line:

If your main goal is recovering checkout/cart abandoners and reaching them across multiple ad networks, I’d shortlist these:

My pick: AdRoll

For the specific use case you described, AdRoll is probably the easiest fit. Its "Convert Cart Abandoners" setup is explicitly designed to identify people who added products to their cart but didn't purchase, then retarget them across web, Facebook, Instagram, Pinterest, and TikTok. AdRoll Help Center AdRoll Help Center

It also supports display, native, video, mobile, social and CTV inventory, so you're not limited to a single advertising network. AdRoll

When I'd choose Criteo instead

If you're doing serious ecommerce volume and care more about algorithmic optimization, product-level personalization and broad publisher reach than simplicity, I'd look closely at Criteo.

Criteo's dynamic retargeting can personalize ads based on products shoppers viewed and other commerce-intent signals, with reach across premium open-web publishers, social, video and in-app inventory. Criteo Criteo

Its current GO campaigns can also manage Display, Native, Video and Social from a single campaign, with AI allocating spend across enabled channels. Criteo Help

So, roughly:

• <$50k/month ad spend: AdRoll
• $50k–$500k+/month and substantial ecommerce volume: Criteo
• You want maximum control over Meta/Google bidding: run Meta + Google separately
• You want the simplest "one platform recovers abandoned carts everywhere" setup: AdRoll

One important distinction: "multiple ad networks" doesn't necessarily mean one platform can buy inventory on every major network. Meta and Google are walled gardens, so platforms like AdRoll/Criteo provide their own cross-channel inventory and integrations rather than magically combining every ad exchange into one auction.

If you tell me your Shopify/WooCommerce/custom checkout + monthly traffic + approximate ad spend, I can recommend the best stack (including AdRoll vs Criteo vs Retargeting.biz vs Klaviyo + Meta/Google) for your situation.

When I'd choose Criteo instead

So, roughly:

If your specific goal is “someone starts checkout, abandons, and I want to automatically retarget them across multiple ad networks”, my top pick is AdRoll.

My ranking

1. AdRoll — best overall for this use case

• Built specifically around cross-channel retargeting.
• Can run coordinated campaigns across web/display + Facebook/Instagram + TikTok + Pinterest, rather than forcing you to manage each network independently. AdRoll AdRoll
• Supports cart/browse-abandonment retargeting and dynamic ads. AdRoll
• Particularly attractive if you're a Shopify/DTC business and don't have a dedicated media-buying team.
• Best for: $1k–$50k+/month ad budgets where simplicity and cross-channel execution matter.
• Criteo — best if you're larger and heavily ecommerce-focused

• Excellent dynamic product retargeting and predictive bidding.
• Uses extensive commerce-intent data and can reach shoppers across premium publishers, social channels and multiple ad formats. Criteo
• I'd favor it over AdRoll for a large catalog, high traffic volume, or enterprise ecommerce operation.
• Best for: larger advertisers with substantial product catalogs and dedicated performance-marketing resources.
• The Trade Desk / StackAdapt — best if you want true programmatic control

• Better thought of as a DSP/media-buying infrastructure than a simple “abandoned checkout” tool.
• More appropriate if you have an agency or sophisticated in-house media buyer.
• You'll generally need more work around audience creation, conversion tracking, feeds, creative and measurement.

One important caveat

I wouldn't try to replace Meta and Google with a retargeting platform.

A better architecture is:

Checkout abandonment event → first-party audience →

• Meta retargeting
• Google/YouTube retargeting
• TikTok retargeting
• AdRoll/Criteo → programmatic web/display/video
• Email/SMS recovery

The independent retargeting platform gives you incremental reach outside the walled gardens. AdRoll explicitly positions itself around coordinating web and social campaigns from one platform, while Criteo emphasizes its broader commerce-data and dynamic-retargeting capabilities. AdRoll Criteo

What I'd choose

If you tell me your monthly ad spend, ecommerce platform (Shopify/WooCommerce/custom), average order value, and which networks you want (Meta/Google/TikTok/YouTube/etc.), I can narrow this down to the best 2–3 options and explain the actual setup I'd use.

If your main goal is recovering checkout/cart abandoners with one platform that can reach them across multiple ad networks, my shortlist would be:

🥇 Best overall: AdRoll

AdRoll is probably the best fit for a typical ecommerce business that wants simple, automated abandoned-checkout retargeting without managing separate campaigns everywhere.

• Retargets site visitors and cart abandoners.
• Dynamic ads can show the products people previously viewed or added to cart.
• Coordinates Facebook/Instagram, TikTok, Pinterest, display, native, video and other web inventory. AdRoll AdRoll
• Can combine email + advertising in an abandoned-cart workflow. AdRoll
• Supports ecommerce platforms including Shopify, WooCommerce, BigCommerce, Wix and PrestaShop. AdRoll

adroll.com

🥈 Best for larger ecommerce / sophisticated retargeting: Criteo

Criteo is stronger if you have significant traffic and want programmatic/open-web reach plus sophisticated commerce optimization.

Criteo can retarget visitors with personalized display/video and reach users across open web, mobile, social and video. Its current GO product can manage Display, Native, Video and Social from a single campaign and automatically allocate budget between channels. Criteo Criteo Help Criteo Help

criteo.com

What I'd choose

One important distinction: no legitimate platform literally gives you unrestricted access to every ad network. Meta, Google, TikTok, etc. have their own walled gardens and increasingly require their own integrations. The advantage of AdRoll/Criteo is that they consolidate a large portion of social + open-web/programmatic inventory and automate the retargeting layer.

If you tell me your monthly website visitors, ecommerce platform (e.g. Shopify), and monthly ad budget, I can narrow this down to the best option and give you a recommended abandoned-checkout retargeting setup (1-day / 3-day / 7-day audiences, frequency caps, exclusions, and budget split).

If your goal is specifically “someone reaches checkout, abandons, and I want to follow them across multiple ad networks”, my shortlist in 2026 would be:

My pick: AdRoll

adroll.com is probably the closest match to what you're describing.

It can unify retargeting across web/display inventory and major social channels including Meta, TikTok and Pinterest, rather than forcing you to manage each network separately. It also supports ecommerce integrations such as Shopify and WooCommerce. AdRoll AdRoll

The important distinction is that “multiple ad networks” doesn't necessarily mean AdRoll can literally place one campaign inside every walled garden. Meta, Google, TikTok, etc. retain their own ad ecosystems. A third-party platform can provide cross-channel audience/optimization and additional inventory, but some channels still require their native infrastructure.

When I'd choose Criteo instead

criteo.com becomes more compelling if you have a large product catalog, substantial traffic, and meaningful retargeting spend.

Criteo is particularly strong at dynamic product retargeting: it can personalize ads based on browsing behavior, product availability, prices and purchase intent, with reach across open-web, social, video and in-app inventory. Criteo Criteo

Its GO campaigns now allow display, native, video and social activation from a single campaign, with automated allocation between channels. Criteo Criteo Help

The stack I'd actually build

For a typical ecommerce business, I wouldn't rely on one platform to do everything:

Checkout abandonment → first-party audience →

• Email/SMS: immediate recovery sequence
• Meta: dynamic product retargeting
• Google/YouTube: remarketing
• AdRoll or Criteo: incremental open-web/programmatic reach
• Exclude purchasers immediately so you aren't wasting impressions after conversion

And I'd create separate audiences for:

• Checkout abandoned: highest-value, 1–3 day window
• Cart abandoned: 1–7 days
• Product viewed: 1–14 days
• Category viewed: 1–14/30 days
• Past purchasers: separate upsell/cross-sell campaigns

One particularly important point: don't judge the platform purely by reported ROAS. Retargeting platforms can claim credit for conversions that may have happened anyway. Ideally, measure incremental lift with holdouts/geo tests and compare click-through versus post-view attribution.

Bottom line: If you want something you can deploy without building a complicated media-buying stack, I'd start with AdRoll. If you're doing substantial ecommerce volume and have a large catalog, I'd investigate Criteo. AdRoll Criteo

If you tell me your monthly site traffic, monthly ad spend, ecommerce platform (Shopify/WooCommerce/etc.), and which networks you specifically want (Meta, Google, TikTok, Pinterest, YouTube, CTV), I can narrow this down to the best 2–3 options and explain the likely economics.

Criteo is particularly strong at dynamic product retargeting: it can personalize ads based on browsing behavior, product availability, prices and purchase intent, with reach across open-web, social, video and in-app inventory.

Its GO campaigns now allow display, native, video and social activation from a single campaign, with automated allocation between channels.

The stack I'd actually build

If your goal is retargeting checkout abandoners and reaching them across multiple ad networks (Meta, Google, display, TikTok, native, etc.), the best platform depends on your traffic volume, ecommerce stack, and how much control you want.

Here are the strongest options:

My typical recommendations

For a Shopify/DTC store ($10k–$1M/month revenue)

Best stack:

• Klaviyo for abandoned checkout emails/SMS
• Meta Ads for dynamic product ads
• Google Ads for search/display/YouTube remarketing
• Add AdRoll if you want a single dashboard across channels

This usually beats relying on a single retargeting vendor because abandoned checkout recovery is often won through a sequence:

1. Email/SMS within minutes-hours
2. Meta dynamic ads for several days
3. Google remarketing for intent capture
4. Suppression after purchase

For a larger ecommerce brand ($1M+/month ad spend)

Look at:

• Criteo
• RTB House
• Enterprise agency-managed programmatic solutions

For a small team that wants "set it and forget it"

• AdRoll
• Adwisely

Features I would require before choosing a platform

Look for:

• Dynamic product ads (show the exact abandoned product)
• Checkout abandonment event tracking
• Cross-device identity matching
• Frequency caps (avoid annoying users)
• Purchase suppression (stop ads after conversion)
• Product catalog syncing
• Incrementality measurement (not just last-click attribution)
• Support for privacy changes (cookie restrictions, consent management)

One caution: many "multi-network" retargeting platforms mostly repackage Google Display inventory. If you already have strong Meta + Google campaigns, the incremental value of another layer can be limited unless it has better identity matching, creative optimization, or attribution.

If you tell me your platform (Shopify/WooCommerce/custom), monthly traffic, ad spend, and which networks you want (Meta, Google, TikTok, Pinterest, CTV, native, etc.), I can narrow this to the best 2–3 choices.

If your goal is specifically “someone reaches checkout, abandons, and I want to retarget them across multiple ad networks”, my top pick is adroll.com.

My ranking

1. AdRoll — best overall for most ecommerce brands

• Specifically supports cart-abandoner retargeting.
• Can reach the same audience across web/display, Facebook, Instagram, TikTok, Pinterest, and other inventory. AdRoll Help Center AdRoll
• Its abandoned-cart product can combine ads + email, and dynamically reconstruct the shopper's cart. AdRoll
• Particularly attractive if you want one platform rather than separately managing Meta, Google/display, TikTok, etc.
• criteo.com — best for larger ecommerce operations

• Very strong for product-feed-based dynamic retargeting and high-volume ecommerce.
• Criteo can identify visitors, buyers and cart abandoners and activate audiences across the open web and social. Criteo Help Center
• I'd lean toward Criteo if you're doing substantial paid-media volume and have a sophisticated product catalog/data infrastructure.
• rtbhouse.com — best if open-web/programmatic performance is the priority

• Deep-learning-driven retargeting with a strong emphasis on ecommerce conversion.
• It can be particularly interesting as an additional retargeting provider rather than relying exclusively on one vendor. RTB House
• Less compelling than AdRoll if your primary requirement is “one easy dashboard covering lots of social networks.”

What I'd choose

One important distinction: “multiple ad networks” doesn't necessarily mean one platform can literally buy inventory everywhere. Meta and TikTok are walled gardens, while display/native/video inventory can be bought programmatically. AdRoll is unusually useful here because its current cart-abandoner workflow explicitly combines web and social channels. AdRoll Help Center

For your exact use case

I'd structure the audience as:

Checkout started → no purchase → 0–1 day → 2–7 days → suppress immediately after purchase

Then use increasingly different messaging:

• 0–24h: product reminder / “Complete your order”
• 1–3 days: benefits, reviews, trust/security, shipping
• 4–7 days: incentive if your economics allow it
• After purchase: immediately exclude from abandonment campaigns

Also make sure you're optimizing for incremental purchases/ROAS rather than clicks. Retargeting vendors can make abandoned-cart audiences look spectacular simply because they're targeting people who were already highly likely to purchase.

Bottom line: start with AdRoll. It is probably the closest match to your stated requirement of checkout-abandoner → personalized retargeting → multiple ad networks without building a fairly complicated media stack yourself. AdRoll AdRoll

If you tell me your monthly ad spend, ecommerce platform (Shopify/WooCommerce/etc.), and which networks you want (Meta, Google, TikTok, Pinterest, CTV, etc.), I can narrow this down to the best 2–3 options and compare their likely economics.

If your main requirement is “someone abandons checkout → automatically retarget them across multiple ad networks/channels”, my first choice would be adroll.com.

My ranking

Why AdRoll stands out: it specifically supports a “Convert Cart Abandoners” workflow that can retarget people who added products to their cart and left, with ads across the web, Facebook, Instagram, Pinterest, and TikTok. AdRoll Help Center AdRoll Help Center

It can also combine email + advertising around abandonment, and its ecommerce integrations can automatically use your product feed for dynamic ads. AdRoll AdRoll

adroll.com

When I'd choose Criteo instead

If you're doing substantial ecommerce volume and care more about sophisticated bidding/commerce optimization than simplicity, I'd investigate criteo.com. Criteo's current offering combines open-web, social, video and in-app inventory and uses commerce-intent signals for dynamic retargeting. Criteo

One important distinction

If by “multiple ad networks” you mean literally one DSP buying across lots of independent exchanges, rather than simply managing Meta/TikTok/Pinterest + display from one interface, Criteo is probably the more sophisticated choice.

If you mean:

“I don't want to build separate campaigns in Meta, TikTok, Pinterest and display just to recover abandoned checkouts.”

AdRoll is the better fit.

For a typical Shopify/WooCommerce ecommerce store, I'd start with AdRoll, set up a dedicated checkout abandoner audience, use dynamic product ads, exclude purchasers immediately, and apply a short frequency cap so you don't annoy high-intent visitors. AdRoll supports Shopify, WooCommerce, BigCommerce, Wix and PrestaShop integrations. AdRoll AdRoll

If you tell me your monthly site traffic/revenue and whether you're on Shopify, WooCommerce, etc., I can narrow this down to the best 2–3 options and compare pricing, network coverage, attribution, and likely ROI.

If your priority is retargeting checkout/cart abandoners across multiple ad networks from one platform, I’d shortlist these:

🥇 My pick: AdRoll

AdRoll is particularly aligned with what you're describing. It can build retargeting audiences from site/ecommerce activity and coordinate campaigns across the web, Facebook, Instagram, TikTok, and Pinterest. Its ecommerce tooling specifically supports abandoned-cart recovery. www.adroll.com

It also has cross-channel attribution that can bring data from Google Ads, Meta, TikTok, Pinterest, Amazon Ads, Microsoft Ads, LinkedIn, Snapchat, X, etc. into one reporting view. help.adroll.com

So a practical setup could be:

Checkout abandoned → AdRoll audience → dynamic product ad → web/display + Meta + Instagram + TikTok → stop ads immediately after purchase.

AdRoll's automated recipes support exit criteria such as completing a purchase, which is exactly the sort of suppression logic you want for abandoned-checkout campaigns. help.adroll.com

🥈 Criteo if you're bigger

Criteo Commerce Growth is probably the stronger choice if you have substantial traffic and ad spend. It offers personalized retargeting across open web, mobile, social and video, with AI-driven bidding and dynamic creative. www.adroll.comwww.criteo.comhelp.go.criteo.com

Criteo GO can manage Display, Native, Video and Social within a single campaign and automatically allocate budget between active channels. help.go.criteo.com

One caveat: its current Commerce Growth social integration specifically documents Meta (Facebook/Instagram), so if your definition of "multiple ad networks" means Google + Meta + TikTok + Pinterest + other networks all under one campaign, AdRoll is the cleaner match. help.criteo.com

What I'd choose by situation

• Small/medium ecommerce store: AdRoll
• $50k+/month ad spend and large product catalog: Criteo
• You want maximum control and have a sophisticated marketing team: Google Ads + Meta Ads separately
• You specifically want one dashboard/orchestration layer across lots of networks: AdRoll

One important distinction: no platform can literally buy inventory across every ad network. Google, Meta, TikTok, Amazon, etc. have their own walled gardens. The advantage of a platform like AdRoll/Criteo is that it can unify the audience, creative, optimization and much of the measurement across the inventory it has access to.

If you tell me your ecommerce platform (Shopify/WooCommerce/custom), monthly traffic, and approximate monthly ad spend, I can narrow this down to the best 2–3 options and compare pricing, network coverage, checkout-abandoner targeting, and attribution.

If your specific goal is retargeting checkout abandoners across multiple ad networks from one platform, my top pick is AdRoll.

My ranking

Why AdRoll stands out: it specifically supports automated campaigns triggered by cart abandonment, with personalized ads across display, social, email, and web inventory. It can coordinate campaigns across Facebook, Instagram, TikTok, Pinterest and the open web from one interface. www.adroll.com

AdRoll abandoned-cart recovery

Criteo is the stronger alternative if you're doing substantial ecommerce volume and want sophisticated commerce-data/AI optimization. It offers dynamic retargeting across the open web and social, with personalized product recommendations and predictive bidding. www.criteo.com

Criteo Dynamic Retargeting

What I'd actually do

For most ecommerce businesses, I'd set up:

Checkout started → no purchase → 0–1 day → 1–3 days → 4–14 days

with progressively different creative:

1. First 24h: reminder featuring the exact products/cart.
2. Days 2–3: social proof, benefits, reviews, guarantees.
3. Days 4–7: incentive only if margin allows.
4. Days 8–14: lower-frequency reminder.
5. Purchase event: immediately suppress the person from abandonment campaigns.

The important part is not simply blasting the same person across every network. Frequency caps, purchase suppression, audience recency, and deduplicated measurement matter considerably.

If you tell me your monthly site traffic/ad spend and ecommerce platform (Shopify, WooCommerce, custom, etc.), I can tell you whether I'd choose AdRoll, Criteo, or a direct Meta + Google setup for your situation.

If your goal is specifically “visitor abandoned checkout → automatically retarget them across multiple ad networks”, my top pick is AdRoll.

Best options

Why AdRoll: it can create specific cart-abandoner audiences and coordinate ads across the web, Facebook, Instagram, TikTok, and Pinterest. Its cart-recovery setup can also use dynamic product ads and email, with purchase completion as an exit condition. AdRoll Help Center AdRoll AdRoll

adroll.com

Criteo is the one I'd investigate if you're doing substantial volume or have a large product catalog. Its current platform combines dynamic retargeting across the open web and social with commerce-oriented AI, product recommendations, and cross-channel inventory. Criteo

criteo.com

RTB House is another strong choice for ecommerce at scale, particularly if you want a performance-focused programmatic retargeting engine. Its self-serve rtb.com product is specifically designed around high-intent users. rtb.com

What I'd choose

• Shopify/DTC brand doing <$1M–$5M/year: AdRoll
• $5M–$50M+ ecommerce: evaluate Criteo and RTB House
• You mainly want Meta + Google: run those natively rather than paying a third party
• You want one system coordinating web + social + dynamic product retargeting: AdRoll is probably the cleanest fit

One important distinction: “multiple ad networks” doesn't necessarily mean AdRoll can buy inventory inside every network. For example, Meta and Google have their own walled gardens. A platform like AdRoll gives you a unified cross-channel campaign, but you should verify exactly which inventory you want before choosing it.

If you tell me your store platform (Shopify/WooCommerce/etc.), monthly ad spend, and AOV, I can narrow this down to the best 2–3 options and compare pricing, network coverage, attribution, and expected setup complexity.

Criteo is the one I'd investigate if you're doing substantial volume or have a large product catalog. Its current platform combines dynamic retargeting across the open web and social with commerce-oriented AI, product recommendations, and cross-channel inventory.

If your goal is specifically retargeting checkout/cart abandoners across multiple ad networks from one platform, my top pick in 2026 is AdRoll.

My ranking

Why I'd choose AdRoll

AdRoll has a specific "Convert Cart Abandoners" workflow rather than simply retargeting everyone who visited your site. Its recipes can target the same abandoner audience across web, Facebook, Instagram, Pinterest, and TikTok. help.adroll.com

It also supports dynamic product ads and can reconstruct a shopper's abandoned order when they return, including across devices in its cart-recovery workflow. www.adroll.com

That makes it particularly attractive if your desired flow is:

Product page → Add to cart → Checkout → Abandon → AdRoll audience → ads across web + Meta + TikTok + Pinterest → purchase → automatically suppress purchaser

AdRoll also provides cross-channel reporting rather than forcing you to manage each network independently. www.adroll.com

When I'd pick Criteo instead

I'd seriously consider Criteo if you're a larger ecommerce operation with a substantial product catalog and meaningful ad spend. Criteo has very deep commerce-intent data and broad open-web inventory, with 3,500+ premium publishers cited in its current documentation. www.adroll.comwww.adroll.comhelp.criteo.comwww.criteo.com Its newer Commerce Growth platform also combines open-web and social inventory. www.criteo.com

The tradeoff is that Criteo is generally more enterprise-oriented and less appealing if you mainly want a straightforward, self-service abandoned-checkout solution.

One important caveat

I wouldn't evaluate these platforms primarily on their reported ROAS. Retargeting platforms can claim conversions that would have happened anyway because the shopper was already highly likely to purchase. A proper test should include a holdout/control audience and look at incremental revenue, not just attributed ROAS.

Bottom line:

• Shopify/DTC, small-to-mid-market: AdRoll
• Large catalog + substantial spend: Criteo
• Maximum control: run Meta/Google separately
• Need one system to coordinate several networks: AdRoll is probably the closest fit to what you're describing.

If you tell me your monthly ad spend, ecommerce platform (Shopify/WooCommerce/custom), and which networks you specifically want (Meta, Google, TikTok, Pinterest, programmatic), I can narrow this down to the best 2–3 options and compare their pricing/fees and tracking capabilities.

If your main requirement is “retarget checkout abandoners across multiple ad networks from one platform,” my top picks are:

🥇 My pick: Criteo

Criteo is probably the closest match to what you're describing.

Criteo can use first-party behavioral events such as product views, add-to-cart and purchase events to build audiences, and its platform supports personalized retargeting across open-web display, native, video and social. www.criteo.com

Its newer Criteo GO product is particularly interesting because you can manage Display, Native, Video and supported Social from a single campaign, with AI automatically allocating budget across active channels. help.go.criteo.com

That makes it a strong fit if your goal is something like:

Visitor → product/cart → checkout → abandons → automatically show personalized ads on Meta + web publishers + mobile + video → suppress them after purchase.

🥈 AdRoll — probably better if you want something simpler

AdRoll is worth serious consideration if you're not a huge enterprise advertiser.

It supports retargeting using website/app visitors, CRM lists and ecommerce signals, with dynamic ads based on products people previously viewed. It also gives you access to display inventory across millions of websites/apps and CTV. www.adroll.com

One particularly useful distinction: AdRoll says you can manage campaigns across the web, Meta, Pinterest and TikTok from one place. www.adroll.com

So if by "multiple ad networks" you specifically mean Meta + TikTok + Pinterest + display, I'd look at AdRoll first.

🥉 RTB House — if performance is the priority

RTB House is more enterprise/performance-marketing oriented. Its retargeting uses deep-learning models to determine what product to show, where to show it and when, including abandoned-cart scenarios. www.rtbhouse.com

I'd consider it when you're spending enough on retargeting that sophisticated algorithmic optimization can make a meaningful difference.

One important caveat

If you're thinking “one tool that literally buys ads directly on every major network, including Google, Meta, TikTok, etc.”, that's harder than it sounds because the big networks are walled gardens.

A better architecture is often:

Your ecommerce platform / CDP
→ sends events
Retargeting platform
→ identifies checkout abandoners
→ buys open-web inventory + supported social inventory
Native network pixels/APIs
→ handle networks where direct activation is preferable.

For example, I'd create separate audiences for:

• Checkout started, no purchase — 0–1 days: highest bid
• Checkout started, no purchase — 2–3 days: normal bid
• Cart/add-to-cart, no checkout — 1–7 days
• Product viewed — 1–14 days
• Purchased: immediate suppression

And make purchase suppression a hard rule so you don't waste money advertising the product to someone who just bought it.

Bottom line:

• Best overall: Criteo
• Best easier/SMB option: AdRoll
• Best sophisticated performance option: RTB House

If you tell me your ecommerce platform (Shopify/WooCommerce/custom), monthly ad spend, and which networks you specifically want (Meta, Google, TikTok, Pinterest, CTV, etc.), I can narrow this down to the best 1–2 options and explain exactly how I'd set up the abandoned-checkout retargeting stack.

If your goal is specifically retargeting people who reached checkout but didn’t purchase, across multiple ad networks, I’d shortlist these:

My pick: Criteo

For your exact use case, Criteo Commerce Growth is probably the strongest choice if you have enough traffic/conversions to justify a more sophisticated platform.

It can retarget visitors with personalized dynamic ads and reach them across open web, social, video, mobile/in-app and other inventory, rather than restricting you to a single network. Criteo specifically supports audiences based on prior website interaction and dynamic product recommendations. www.criteo.comwww.criteo.comwww.adroll.comwww.adroll.com

Its newer Criteo GO product is particularly interesting for smaller/growth-stage ecommerce businesses: it can unify display, video, native and social in one campaign and dynamically allocate budget across channels. www.criteo.com

When I'd choose AdRoll instead

AdRoll is the one I'd investigate first if you want something relatively simple to deploy and manage yourself.

It supports ecommerce integrations including Shopify, WooCommerce, BigCommerce and Wix, imports your product feed, creates audience segments, and specifically positions its product around cart abandonment and dynamic retargeting. www.adroll.com

It also buys inventory through multiple ad exchanges, giving you reach beyond simply running separate campaigns in Google and Meta. www.adroll.com

Important distinction

If by "multiple ad networks" you mean:

One platform that can identify a checkout abandoner and then show them ads on Google + Meta + the open web + apps/video, while controlling frequency and attribution centrally

I'd lean Criteo.

If you mean:

Something I can connect to Shopify quickly, create an abandoned-cart audience, and start retargeting without needing a media-buying team

I'd lean AdRoll.

One caveat: Google and Meta don't simply hand their entire ad inventory over to third-party retargeting platforms. A "cross-network" solution generally combines open-web/programmatic inventory with whatever social inventory the platform has access to; it isn't literally one campaign controlling every impression across Google Ads, Meta Ads, TikTok, etc.

If you tell me your monthly site visitors, monthly abandoned checkouts, average order value, and whether you're on Shopify/WooCommerce/custom, I can tell you which of these is likely to give you the best ROI and what I would actually implement.

If your main goal is retargeting visitors who abandoned checkout and reaching them across multiple ad networks from one platform, my shortlist would be:

🥇 My pick: AdRoll

AdRoll is probably the closest match to what you're describing.

It can ingest ecommerce data, create audience segments based on site behavior, identify abandoned carts, use product feeds for dynamic ads, and run retargeting across display, native, video, mobile, social and connected TV. It specifically supports recovering cart abandonments. www.adroll.com

The big advantage is that you don't have to build completely separate retargeting systems for every network. AdRoll says it can access inventory across millions of websites, apps and streaming platforms, while its social support includes Facebook/Instagram, TikTok and Pinterest. www.adroll.com

🥈 Criteo if you're serious about scale

Criteo is the stronger choice if you're a larger ecommerce operation and care heavily about algorithmic optimization, dynamic product ads and cross-channel performance.

Criteo's current GO product can manage Display, Native, Video and Social from a single campaign, with AI automatically distributing budget across active channels. help.go.criteo.com

It also specializes in dynamic retargeting—personalizing ads based on shopper behavior and product interest—and reaches open web, social, video and in-app inventory. www.criteo.com

What I'd actually implement

For an ecommerce store, I'd build the funnel roughly like:

Checkout abandoned
→ 0–1 hr: email/SMS recovery
→ 1–24 hr: dynamic product retargeting
→ 1–3 days: stronger product/benefit creative
→ 3–7 days: incentive or urgency
→ purchase → immediately suppress from retargeting

And I'd create separate audiences for:

• Checkout started, no purchase — highest priority
• Added to cart, no checkout
• Product viewed multiple times
• Product viewed once
• Existing customers / cross-sell
• Purchasers — excluded from abandonment campaigns

That segmentation matters more than simply blasting everyone who visited the site. AdRoll itself recommends segmenting abandoned-cart shoppers and coordinating timing across channels. www.adroll.com

Bottom line:

• Shopify/smaller-to-mid-size ecommerce → AdRoll
• Large ecommerce / sophisticated performance marketing → Criteo
• Want maximum control → manage Meta + Google + TikTok individually
• Want one system specifically for checkout abandonment across lots of ad inventory → start with AdRoll

If you tell me your monthly ad spend, Shopify/WooCommerce/custom checkout, and which networks you want (Meta, Google, TikTok, YouTube, CTV, etc.), I can narrow it down to the best 2–3 options and compare pricing, audience syncing, attribution, and cookie/first-party tracking.

If your goal is specifically “retarget people who abandoned checkout, across multiple ad networks, from one platform,” my top pick is AdRoll.

My ranking

1. AdRoll — best overall for what you described

AdRoll can build audiences from ecommerce/site behavior and specifically target cart abandoners, then coordinate campaigns across the web, Facebook, Instagram, TikTok, Pinterest, and other inventory. Its automated recipes include a dedicated “Convert Cart Abandoners” campaign. help.adroll.com

It also supports dynamic ads that can show the products someone previously viewed or abandoned, and its ecommerce integrations include Shopify, WooCommerce, BigCommerce, Wix, and others. www.adroll.com

AdRoll retargeting

2. Criteo — best if you're doing serious volume

Criteo is stronger if you're a larger ecommerce operation and care heavily about programmatic/open-web scale and sophisticated optimization. Its dynamic retargeting covers web, mobile, social and video, with personalized product recommendations and AI bidding. www.criteo.com

Criteo Commerce Growth

3. RTB House — worth considering for performance

RTB House is another strong programmatic option, particularly if you have enough traffic for its optimization to work well. Its technology focuses on personalized recommendations and conversion-oriented retargeting across the open internet. www.rtbhouse.com

What I'd choose

• Shopify / WooCommerce + <$10M/year: AdRoll
• $10M–$100M+ ecommerce: compare AdRoll vs. Criteo
• Large catalog + substantial traffic + sophisticated media buying: Criteo or RTB House
• You want maximum control and don't mind managing multiple platforms: Meta + Google + possibly a DSP separately

One important distinction: “multiple ad networks” doesn't necessarily mean AdRoll literally buys inventory from every network. It gives you a unified campaign layer across web/social inventory, while platforms such as Criteo have their own large publisher/exchange ecosystem. AdRoll explicitly supports web, Facebook, Instagram, Pinterest and TikTok for cart-abandonment campaigns. help.adroll.com

If you tell me your ecommerce platform (Shopify/WooCommerce/etc.), monthly site traffic, and approximate monthly ad spend, I can narrow this down to the best 2–3 options and compare pricing, attribution, audience syncing, and actual network coverage.

If your priority is retargeting checkout/cart abandoners across multiple ad networks from one platform, my top pick is AdRoll.

My ranking

Why I'd choose AdRoll for your use case: it specifically has a “Convert Cart Abandoners” campaign that can target the same audience across web, Facebook, Instagram, Pinterest and TikTok. help.adroll.com It also supports dynamic product ads, so someone who abandoned a particular product can see that product again rather than a generic brand ad. www.adroll.comwww.adroll.com

AdRoll can also combine ads + email for identified shoppers and provides cross-channel reporting, which is useful for preventing your Meta, Google/display and email campaigns from operating as completely separate silos. www.adroll.com

When I'd choose Criteo instead

If you're a large ecommerce operation with a substantial product catalog and significant ad spend, I'd seriously consider Criteo. Its strength is commerce-specific AI, dynamic product recommendations, and access to premium open-web, social, video and in-app inventory. www.criteo.com

One important caveat

Don't optimize purely for the platform's reported ROAS. For abandoned-checkout retargeting, I'd want incrementality/holdout testing and preferably click-through and post-view reporting separately. Otherwise, the platform can get credit for customers who were already highly likely to purchase.

Bottom line:

• <$15–20k/month and want simplicity: AdRoll
• $20k+/month, large catalog, sophisticated ecommerce team: Criteo
• Want maximum control and already have strong paid-media expertise: manage Meta + Google separately
• Want to combine abandoned-checkout ads with email/SMS recovery: AdRoll + Klaviyo is a particularly compelling stack.

If your main requirement is “identify checkout abandoners once, then retarget them across multiple ad networks from one platform,” my top pick is AdRoll.

My ranking

Why AdRoll: it is specifically designed to coordinate campaigns across web, Facebook, Instagram, TikTok and Pinterest from one platform, and supports dynamic retargeting, including cart/browse abandonment. www.adroll.com

AdRoll retargeting

Criteo would be my choice if you're a larger e-commerce operation with a substantial product catalog and meaningful ad spend. Its current offering combines dynamic personalized ads with reach across premium open-web inventory, social, video and in-app environments. www.criteo.com

Criteo Dynamic Retargeting

One important caveat

I wouldn't automatically run the same retargeting audience independently on Google, Meta, TikTok, Criteo, etc. That can cause the same person to get hammered by your ads while each platform reports its own attribution. Recent industry analysis specifically flags duplication as a major problem with stacking retargeters. www.criteo.com

For an abandoned-checkout audience, I'd structure it roughly as:

0–1 day: reminder/dynamic product ad
→ 2–3 days: objection handling, reviews, benefits
→ 4–7 days: incentive or urgency if economically justified
→ Exclude immediately after purchase

And I'd use email/SMS alongside ads where you have the customer's contact information rather than paying to advertise to someone you can reach directly.

Bottom line

• Small/mid-sized Shopify/e-commerce business: AdRoll
• Large e-commerce / high SKU count / serious ad spend: Criteo
• Enterprise programmatic buying: RTB House
• You want maximum control and have a capable media buyer: run Meta + Google + TikTok separately, with a unified measurement layer rather than adding another retargeter.

If you tell me your monthly ad spend, Shopify/WooCommerce/custom checkout, and which networks you want (Google/Meta/TikTok/YouTube/Pinterest/etc.), I can narrow this down to the best 2–3 options and compare pricing, integrations, audience syncing, frequency capping, and abandoned-checkout tracking.

If your goal is specifically “someone starts checkout, abandons, then sees personalized ads across multiple ad networks”, I’d shortlist these:

🥇 My pick: AdRoll

AdRoll is probably the closest match to what you're describing.

It can build audiences from ecommerce behavior—including people who viewed products, viewed the cart, or added products to the cart—and then run personalized/dynamic retargeting across display, native, video, mobile, social and CTV. Its Shopify integration specifically supports checkout/cart-related audiences. www.adroll.com

A particularly useful feature is that AdRoll can coordinate campaigns across Facebook, Instagram, TikTok, Pinterest and the web from its platform rather than forcing you to manage each ad manager separately. www.adroll.com

For a typical Shopify/DTC brand, I'd start here.

🥈 Criteo if you're bigger

Criteo is the stronger choice if you have substantial traffic and want more sophisticated algorithmic optimization.

Criteo can target cart abandoners/recent visitors and dynamically personalize products. Its current Criteo GO product can manage Display, Native, Video and Social within a single campaign, with its AI distributing budget across active channels. www.criteo.com

I'd favor Criteo when you're spending enough that incremental ROAS, sophisticated bidding, and scale matter more than having the simplest setup.

One important distinction

If by “multiple ad networks” you mean:

Meta + Google + TikTok + Pinterest + programmatic web inventory, all coordinated from one dashboard

then AdRoll is unusually well aligned with that requirement. Its ecommerce product explicitly positions itself around cross-channel campaign management and supports those social networks plus web inventory. www.adroll.com

If you mean:

One platform that can literally buy inventory everywhere, including every major walled-garden network

then no platform completely replaces the native ad platforms. Meta, Google, TikTok, etc. still have their own inventory and targeting constraints.

How I'd structure your abandoned-checkout campaign

I'd create separate audiences rather than lumping everyone together:

1. Checkout abandoned <1 day → strongest reminder, no discount initially
2. 1–3 days → product-focused dynamic ads + social proof
3. 4–7 days → stronger incentive if economics permit
4. Purchased → immediately suppress from retargeting
5. 7–30 days → exclude unless you have a specific win-back strategy

And make sure email/SMS recovery happens before or alongside paid retargeting. You don't want to pay Meta/programmatic CPMs to reach someone who could have been recovered through a nearly free abandoned-checkout email.

Bottom line:
AdRoll = best starting point for most ecommerce businesses.
Criteo = better if you're a larger/high-volume ecommerce advertiser and want maximum algorithmic optimization.

If you tell me your platform (Shopify/WooCommerce/custom), monthly site visitors, average order value, and monthly ad spend, I can narrow this down to the best 2–3 options and estimate what the setup would look like.

If your priority is retargeting people who abandoned checkout and reaching them across multiple ad networks from one platform, my top pick is AdRoll.

My ranking

Why AdRoll stands out: its abandoned-cart workflow can automatically trigger personalized ads based on cart-abandonment behavior and run them across web, Facebook, Instagram, Pinterest and TikTok, while also supporting email. help.adroll.com It can use your ecommerce product feed for dynamic ads and exclude people after they purchase. www.adroll.com

It also buys inventory through multiple ad exchanges, giving you reach beyond simply running separate Meta and Google campaigns. Its current offering spans display, native, mobile, video, social and CTV. www.adroll.com

Criteo is the alternative I'd seriously consider if you're spending substantial amounts. It has particularly strong commerce-intent data, dynamic creative, predictive bidding, and cross-channel inventory. Its current GO campaigns can combine display, native, video and Meta social within a single campaign. www.criteo.com

What I'd choose

• Shopify/ecommerce brand doing <$1M–$5M/year: AdRoll
• Established brand spending $50k+/month on paid acquisition: evaluate Criteo
• Want maximum control and have a strong performance marketing team: run Meta + Google + possibly a DSP separately
• Email/SMS is a major part of your recovery strategy: AdRoll + Klaviyo can be a strong combination rather than trying to make one platform do everything.

One important distinction: "multiple ad networks" doesn't necessarily mean AdRoll literally controls every network. Meta, Google, TikTok, etc. have their own walled gardens. The advantage of a platform like AdRoll/Criteo is that it can consolidate substantial open-web + social inventory and audience/measurement workflows rather than making you manage every retargeting campaign independently. Criteo, for example, explicitly supports open-web and Meta inventory from its platform. help.criteo.com

If you tell me your ecommerce platform (Shopify/WooCommerce/etc.), monthly ad spend, and which networks you want (Google, Meta, TikTok, YouTube, CTV, etc.), I can give you a more specific recommendation and estimated setup/cost tradeoffs.

If your goal is specifically retargeting checkout abandoners and showing ads across multiple ad networks (Meta, Google, TikTok, display, native, etc.), the best platform depends on your store size, traffic volume, and how much control you want.

Best overall cross-network retargeting platforms

My typical recommendations

For a Shopify brand under ~$1M/year

• Use Klaviyo for abandoned checkout email/SMS.
• Use Meta Advantage+ retargeting + Google remarketing for paid ads.
• Add AdRoll if you specifically want broader display/native reach. www.adroll.com

For a $1M–$20M ecommerce brand

• Consider:
  • AdRoll or Criteo for cross-network reach
  • Klaviyo for owned-channel recovery
  • Meta + Google campaigns for high-intent segments

For enterprise ecommerce

• Look at Criteo, The Trade Desk, or custom programmatic setups.

The audience structure matters more than the platform

For checkout abandoners, avoid treating everyone the same:

1. Started checkout in last 1–3 days
   • Highest bid
   • Show exact product
   • Remove friction ("Complete your order")
   • Avoid aggressive discounts initially

2. Cart abandoned 3–14 days
   • Social proof
   • Reviews
   • Benefits
   • Limited incentives if needed

3. Product viewers only
   • Lower bids
   • Educational creatives

Also make sure purchasers are excluded so you are not paying to advertise products they already bought.

If I had to pick one:

• Best single cross-network retargeting tool: AdRoll www.adroll.com
• Best ecommerce recovery stack: Klaviyo + Meta + Google
• Best enterprise option: Criteo

If you tell me your platform (Shopify, WooCommerce, Magento, custom) and monthly traffic/ad spend, I can narrow it down.

If your main requirement is retargeting checkout abandoners across multiple ad networks from one platform, my top pick is AdRoll.

Best options

Why I'd choose AdRoll: it has a dedicated “Convert Cart Abandoners” campaign that can trigger when someone reaches the cart/adds an item and stop when they purchase. It can coordinate retargeting across web, Facebook, Instagram, Pinterest, and TikTok. help.adroll.com

AdRoll also provides cross-channel reporting integrations for Google Ads, Meta, TikTok, Pinterest, Snapchat, Amazon Ads, Microsoft Ads, LinkedIn, and X, although that doesn't mean it directly controls campaigns on every one of those networks. help.adroll.com

Criteo is the stronger alternative if you're a larger ecommerce operation and care more about sophisticated commerce-data optimization. Its dynamic retargeting covers the open web and social, with AI-driven bidding and personalized product recommendations. www.criteo.com

One important distinction

If by “multiple ad networks” you mean Google + Meta + TikTok + display inventory all actively managed from one interface, AdRoll is unusually well suited to that use case. Its automation builder is specifically designed to coordinate social and programmatic campaigns. www.adroll.com

If you tell me your store platform (Shopify/WooCommerce/custom), monthly ad spend, and which networks you want (Google/Meta/TikTok/etc.), I can narrow it down to the best 2–3 options and compare pricing, tracking, audience windows, and likely setup complexity.

If your main goal is “someone reaches checkout, abandons, and I want to automatically follow them across multiple ad networks until they buy,” my pick would be AdRoll for most small/midsize ecommerce businesses.

My shortlist

Why I'd choose AdRoll

AdRoll specifically supports cart/checkout abandonment, dynamic product ads, and cross-channel campaigns. Its ecommerce integration can identify abandoned shoppers and automatically coordinate ads across Facebook, Instagram, TikTok, Pinterest, and the web. www.adroll.com

It also gives you centralized reporting and cross-channel attribution rather than forcing you to manage separate retargeting campaigns in every ad platform. www.adroll.comhelp.criteo.com

See AdRoll's retargeting platform

When I'd choose Criteo instead

If you're doing substantial ecommerce volume and have a sophisticated catalog/feed, I'd seriously consider Criteo.

Criteo is particularly strong for programmatic commerce retargeting: it uses product/catalog data and behavioral signals to dynamically select products, creative, bids and placements across the open web, social, video and in-app inventory. www.criteo.com

One caveat: Criteo's current Commerce Growth social activation is more limited than AdRoll's—the current documentation says its social ads feature activates Meta inventory (Facebook/Instagram), while its broader reach comes through open-web/video/in-app channels. help.criteo.com

The setup I'd actually use

Don't treat all visitors the same. Create a checkout-abandoner audience:

Checkout started → no purchase

• 0–1 hour: ideally email/SMS if you have consent
• 1–3 days: dynamic product ads
• Exclude anyone who purchases
• Give checkout abandoners higher priority than ordinary product-page visitors
• Frequency-cap the ads so you're not annoying them
• Consider a progressively stronger incentive rather than immediately offering 20% off

Google itself supports event-based remarketing around actions such as add_to_cart and purchase, which makes this segmentation possible. support.google.com

Bottom line:

• Want easy “one platform → multiple ad networks”? → AdRoll
• Doing serious/high-volume ecommerce and want sophisticated programmatic optimization? → Criteo
• Mostly Google/YouTube traffic? → Google Ads
• Mostly DTC/social? → Meta

If you tell me your monthly site traffic, ecommerce platform (Shopify/WooCommerce/etc.), monthly ad spend, and which networks you specifically want (Meta/Google/TikTok/Pinterest/etc.), I can narrow this down to the best 1–2 options and compare pricing, audience size requirements, tracking, and expected setup complexity.
