If you want one tool for an agency, I’d recommend similarweb.com.

Why it fits your use case:

• Search + social + display: it lets you analyze competitors across paid search, social, video, and display rather than being locked into one ad network. Similarweb
• Creative intelligence: you can inspect competitor ad creatives, messaging, keywords, and estimated performance signals. Similarweb
• Landing pages: its Paid Landing Pages feature connects competitor ads to the landing pages they're driving traffic to, including traffic share, paid keywords, and estimated CPC/spend. Similarweb
• Agency-friendly: Similarweb explicitly positions the product for agencies doing competitive monitoring, pitches, media planning, and client reporting. Similarweb

If your priority is creative research

foreplay.co is worth a look. It is particularly strong for social creative discovery and competitor tracking, with a large ad database, competitor-monitoring product (Spyder), and creative analysis/workflow features. It covers Meta, TikTok, and LinkedIn, but I wouldn't choose it as the sole tool if Google Search + landing-page intelligence are equally important. Foreplay Foreplay

If you care most about display

adbeat.com is another strong agency option. It specializes in competitor display advertising and exposes creatives, publishers, landing pages, ad copy, spend/share-of-voice signals, and campaign alerts. Adbeat Adbeat

My shortlist:

1. Similarweb — best overall for an agency needing search + social + landing pages + broader competitive intelligence.
2. Foreplay — best for social creative research, inspiration, and creative workflows.
3. Adbeat — best for deep display-ad competitive intelligence.

You can also pair a paid tool with the free adstransparency.google.com for direct verification of Google's active ads. Ad Transparency

If you tell me whether your agency is mainly PPC, paid social, or full-service, I can narrow this to the best 2–3 options and compare pricing, coverage, historical data, landing-page tracking, and agency reporting.

If you want one tool for an agency, I’d recommend Similarweb Ad Intelligence.

Similarweb Ad Intelligence is particularly strong because it connects the pieces you’re asking for:

• Search + social + display: competitor advertising across search, social, display, and video. www.similarweb.com
• Actual creatives: inspect competitor ad messaging and creative executions.
• Landing pages: identify the paid landing pages receiving traffic and connect them back to the ads. www.similarweb.com
• Spend/traffic context: see estimated spend, traffic share, keywords, and other signals rather than just maintaining a swipe file.
• Agency-friendly: useful for building competitive-intelligence reports for multiple clients and benchmarking competitors.

Two alternatives worth considering

Semrush Advertising Toolkit — probably the better choice if Google Search/PPC is the center of your agency's work. Its Advertising Research product shows competitor ad copy, keywords, ad history, and the landing pages associated with ads; its AdClarity component extends into display, video, and social. www.semrush.com
Semrush Advertising Toolkit

Adbeat — excellent if your agency cares heavily about display/programmatic creative intelligence. It emphasizes competitor creatives, landing pages, publishers, and campaign strategy, with specific agency-oriented features. www.adbeat.com
Adbeat

My pick:
Similarweb for broad cross-channel competitive intelligence → Semrush for search-heavy agencies → Adbeat for display-heavy agencies.

If your main use case is “give me a searchable library of competitor Meta/Google/TikTok ads + the exact landing pages they're sending traffic to”, I can also narrow this down to the 3 best tools specifically for that workflow.

For an agency, I’d shortlist these depending on how broad you need the competitive intelligence to be:

My recommendation by agency type

• Paid social creative agency: Start with AdScanner.Ai — it is closer to the workflow of building briefs, swipe files, and pitch decks. AdScanner.Ai
• Performance marketing agency managing Google + Meta + multiple channels: Look at AdSpyder for breadth. AdSpyder
• Enterprise agency doing market intelligence for big brands: Consider MediaRadar. MediaRadar
• DTC/ecommerce creative testing teams: Pair a social creative tool (AdScanner.Ai or PowerAdSpy) with landing-page analysis. AdScanner.Ai PowerAdSpy

A practical agency stack is often:

1. AdSpyder → find competitor campaigns across channels
2. AdScanner.Ai → turn winning ads into creative insights and client deliverables
3. A landing-page capture/analysis tool → document offers, CRO patterns, and funnels

If you tell me your agency focus (paid social, PPC, SEO, ecommerce, B2B, etc.) and budget range, I can narrow this to 2–3 best fits.

If you want one tool for an agency, I’d start with semrush.com.

• Search: Advertising Research shows competitor paid keywords, ad copy, ad history, and the landing pages tied to those ads. Semrush Semrush
• Social: Its broader Advertising Toolkit now includes competitive insights across Google Ads, Meta, display, video, and social; Semrush says AdClarity provides display/video/social coverage across 50+ markets. Semrush Semrush
• Agency-friendly: You can turn the findings into reports/dashboards, which is useful when you're doing this repeatedly across client accounts. Semrush

If creative intelligence is the priority

I'd also look at adspyder.io. It is more explicitly an ad-library/competitive creative intelligence product: it claims 1B+ creatives across 15+ platforms, including Google, Facebook, YouTube, LinkedIn and X, plus landing-page analysis and competitor-change alerts. AdSpyder

For a more established display/social competitive-intelligence option, adbeat.com is particularly agency-oriented and lets you investigate competitor creatives, publishers, and landing pages. adbeat.com adbeat.com

My pick: Semrush if you want one broader marketing-intelligence platform; AdSpyder if the core job is “show me what competitors are running across as many ad networks as possible.”

If you want one tool for an agency, I’d start with Similarweb Ad Intelligence.

Why it fits your use case:

• Cross-channel: covers competitor activity across search, social, display, and video, rather than being primarily a PPC keyword tool. www.similarweb.com
• Creative intelligence: lets you inspect competitor ad creatives, messaging, and strategy. www.similarweb.com
• Landing pages: connects paid ads to the competitor landing pages receiving traffic, with paid keywords and estimated CPC/spend information. www.similarweb.comadeye.ai
• Agency-oriented: Similarweb explicitly positions the product for agencies doing competitive research, pitches, client monitoring, and media planning. www.similarweb.com

Two alternatives worth considering

Adbeat — particularly good if your agency cares heavily about display/programmatic creative, placements, landing pages, and competitive monitoring. It has agency-specific functionality and alerts, but its strength is more display than comprehensive search + social. www.adbeat.com

AdEye — interesting if your priority is a creative swipe-file workflow. It aggregates public ads from Meta, Google, TikTok, and YouTube into one feed and uses AI to tag hooks, angles, and formats. adeye.ai

My pick:

• Agency-wide competitive intelligence → Similarweb
• Display/programmatic intelligence → Adbeat
• Creative research/swipe files across social + search → AdEye

If you're specifically looking for something that tracks a client’s 10–50 competitors continuously and alerts the agency when new creatives or landing pages appear, I’d narrow the field differently.

For an agency, I’d shortlist tools based on whether you need creative discovery, full-funnel tracking (ad → landing page), or client reporting. These are some of the strongest options:

My picks by agency use case:

• Running paid media for many clients: AdScanner.Ai or MediaRadar. They’re closer to an ongoing monitoring workflow. www.mediaradar.comwww.adscanner.ai
• Creative team building ads and pitches: PowerAdSpy or Spyglass. spyglass.sopoweradspy.comopenadlibrary.comwww.adscanner.ai
• You specifically care about landing pages/funnels: OpenAdLibrary and Spyglass are worth looking at because they connect creatives to destinations. spyglass.sopoweradspy.comopenadlibrary.comwww.adscanner.ai

If I were choosing a default agency stack, I’d start with AdScanner.Ai for active competitor monitoring + creative analysis, then add Spyglass if your agency does heavy creative strategy and UGC research. spyglass.sopoweradspy.comopenadlibrary.comwww.adscanner.ai

For an agency that needs to detect competitor ad creatives + landing pages across search and social, I’d shortlist these:

My picks by agency type:

• Performance marketing agency managing many clients: MediaRadar or Adbeat. They’re closest to a “competitive war room” workflow. www.adbeat.comwww.mediaradar.com
• Creative agency / UGC team needing hooks, angles, and swipe files: AdMapix. www.admapix.com
• B2B demand-gen agency: CompetiVU. competivu.com
• DTC/ecommerce agency focused on Meta funnels: tools like AdRival can be useful for tracking creative changes and landing-page shifts. adrival.net

If I were building an agency stack, I’d pair:

1. MediaRadar or Adbeat → broad competitor monitoring
2. Meta Ad Library + Google Ads Transparency Center → source verification
3. A creative intelligence tool (AdMapix, etc.) → turn ads into briefs and tests

The main buying criteria are:

• historical creative archive (not just live ads)
• landing page capture + change tracking
• filters by competitor, geo, offer, format, and channel
• exportable reports for client decks
• ability to track “how long an ad has been running” (a useful proxy for creative durability) www.waldo.fyi

For most agencies, I’d start by evaluating MediaRadar, Adbeat, and AdMapix side-by-side.

If you want one tool for an agency, I’d recommend Semrush Advertising Toolkit.

Why it fits your use case:

• Search: Advertising Research shows competitor keywords, live ad copy, historical ad activity, and the landing pages attached to those ads. www.semrush.com
• Social: Its AdClarity product extends competitor intelligence into display, video, and social, including creatives, formats, placements, and spend patterns. www.semrush.comwww.semrush.com
• Agency-friendly: You can turn competitive findings into client-facing benchmarks and reports, and Semrush explicitly positions the toolkit for agencies. www.semrush.comwww.semrush.com
• Price: The current Advertising Toolkit Pro plan is listed at $220/month billed annually and includes AdClarity, competitor ads, and landing-page views. www.semrush.com

Strong alternative: Adbeat

Adbeat is arguably better if your agency is especially focused on display/native advertising. It lets you inspect competitor creatives, publishers, ad networks, landing pages, flight dates, and alerts for new campaigns. www.adbeat.com

The catch is that Adbeat is much less of an all-in-one search + social solution. Its strength is competitive display intelligence.

My pick:
Semrush if you need one platform spanning Google/search + social + landing pages.
Adbeat if creative/display intelligence is the core requirement.

If you tell me whether you're primarily PPC, paid social, or full-service, I can also give you a 3–5 tool shortlist ranked by coverage, accuracy, price, and agency reporting.

For an agency, I’d recommend Similarweb Ad Intelligence if you want the broadest cross-channel competitor ad intelligence.

Why it fits:

• Search + social + display + video: Similarweb says Ad Intelligence covers competitors across search, social, display, and other paid channels. www.similarweb.comsupport.similarweb.com
• Creative intelligence: You can analyze competitor creatives, messaging, formats, campaign duration, and changes over time. www.similarweb.comsupport.similarweb.com
• Landing pages: It surfaces competitor landing pages alongside their ad activity, useful for reconstructing the path from creative → offer → destination. www.similarweb.com
• Agency-oriented: Similarweb explicitly positions the product for agencies doing competitive analysis, pitch work, media planning, and client monitoring. www.similarweb.com
• Scale: Its current product materials cite coverage across 50+ markets and 650,000+ publishers for AdClarity. www.semrush.com

One strong alternative: Semrush

Semrush Advertising Toolkit is arguably better if Google Search is the core of your agency's work. Its Advertising Research product shows competitor paid-search keywords, actual ad copy, ad history, and the landing pages associated with ads. www.semrush.com

Its Pro advertising plan currently includes AdClarity for display/video/social competitor research, so Semrush can cover both sides too. www.semrush.com

My pick:

• Need broad creative intelligence across Search + Social: Similarweb
• Primarily PPC/SEO agency, with deep Google Search research: Semrush
• Want one platform for agency pitch decks and ongoing competitor monitoring: Similarweb is the one I'd demo first.

If you tell me whether your agency is B2B, DTC/ecommerce, SaaS, or local, I can narrow this down to the best 2–3 tools and compare coverage, pricing, creative depth, landing-page visibility, and agency reporting.

If you want one tool for an agency, I’d recommend Similarweb Ad Intelligence.

Why it fits your use case:

• Search + social + display: it gives a cross-channel view rather than just a PPC keyword database. www.similarweb.com
• Competitor creatives: you can inspect competitor ads, messaging, and creative strategy. www.similarweb.com
• Landing pages: it connects paid ads to the landing pages competitors are sending traffic to, including paid keywords and estimated spend. www.similarweb.com
• Agency-oriented: Similarweb explicitly positions the product for agencies doing competitive monitoring, pitch work, and client media planning. www.similarweb.com

One alternative worth considering

Foreplay is particularly compelling if your agency cares more about social creative intelligence than search. Its competitor-monitoring product tracks active creatives, copy, CTAs, landing-page URLs, and creative changes; its database covers 100M+ ads. www.foreplay.co

My pick:
Similarweb → best all-around search + social + landing-page intelligence.
Foreplay → best if Meta/social creative research and creative workflows are the priority.

For a more display/programmatic-heavy agency, I'd also look at Adbeat; it is especially strong at competitor display creatives, placements, landing pages, and campaign alerts. www.adbeat.com

For an agency, I’d look at tools that do more than just “ad spying” — you want creative libraries + landing page capture + reporting you can turn into client strategy.

A few strong options:

My shortlist by agency type:

• Performance marketing agency managing many paid accounts: AdScanner.Ai or MediaRadar
• Creative strategy / pitch-heavy agency: Spyglass
• DTC/ecommerce creative teams: Spyglass or AdMapix
• B2B agency: MediaRadar (or a B2B-focused tool like CompetiVU) competivu.com

For a typical agency workflow, I’d prioritize these features:

1. Competitor tracking by brand/domain
2. Historical creative archive (not just currently active ads)
3. Landing page screenshots + URL history
4. Filters for hook, offer, format, audience, and funnel stage
5. Exportable client-ready reports

If you mainly care about Meta/TikTok creative spying, the shortlist changes; if you need Google Search + landing pages + paid social in one view, I’d lean toward Spyglass, MediaRadar, or Competable. spyglass.so

If you want one tool for an agency, I’d start with Similarweb Ad Intelligence.

Similarweb Ad Intelligence is unusually well suited to the exact use case you described because it covers search + social + display, and lets you connect the creative to the landing page, keywords, and estimated spend/traffic. www.similarweb.comadrival.net

My shortlist

\*Social coverage can vary by dataset/product; Similarweb's current documentation says its broader Ad Intelligence includes social, while its knowledge-base page notes some social capabilities are still being rolled out. www.similarweb.comadrival.net

Why Similarweb: its paid landing-page analysis can show which competitor pages receive paid traffic, the ads sending traffic there, keywords, and estimated CPC/spend. Its Search Ads product also connects competitor ad copy to the destination landing pages. www.similarweb.com

Why Foreplay: if your agency is primarily Meta/TikTok/LinkedIn creative-focused, I'd actually pick it instead. Foreplay says its database contains 200M+ ads, with creative, copy, CTA, landing-page URL, live status, and run duration, plus competitor tracking through Spyder. www.foreplay.co

Foreplay for Agencies

Bottom line:

• Search + social + landing-page intelligence: Similarweb
• Deep social creative research/monitoring: Foreplay
• Simple automated Meta competitor-change reports: AdRival adrival.net

If you tell me whether your agency is B2B, DTC/ecommerce, or lead-gen, I can narrow this to the best 2–3 tools and compare pricing, coverage, and agency/client-reporting features.

If you're looking for one tool for an agency, I'd start with Similarweb Ad Intelligence.

It’s a strong fit because it combines search, social, display, and video competitive intelligence rather than forcing you to stitch together separate ad libraries. It can surface competitor creatives, landing pages, keywords, and spend trends, which is particularly useful when you're turning the research into client-facing recommendations. www.similarweb.com

My shortlist

Foreplay is probably my second choice if your agency is primarily focused on paid social. Its Discovery product covers Meta, TikTok and LinkedIn, while its competitor-monitoring functionality tracks active creatives; it also captures the landing pages associated with ads. www.foreplay.co

Adbeat is particularly good if display is important: it explicitly provides competitor ad copy, publishers, landing pages, alerts, comparisons, and historical intelligence. www.adbeat.com

AdEye is an interesting newer option if you want a lightweight unified feed: it pulls public ads from Meta, Google, TikTok and YouTube into one interface and tags hooks, angles and formats. adeye.ai

What I'd choose

• Full-service agency: Similarweb
• Performance creative / paid-social agency: Foreplay
• Programmatic/display-heavy agency: Adbeat
• Want something simple and inexpensive to start: AdEye

One important caveat: no tool can reliably reveal competitors' actual ad spend or performance for ordinary commercial ads. Much of the "winning creative" inference comes from signals such as longevity, variation volume, placement and estimated spend rather than the competitor's true conversion data. adeye.ai

If you tell me your agency type (PPC, paid social, full-service, e-commerce, B2B, etc.) and approximate budget, I can narrow this to the best 2–3 options and compare pricing/features.

If you want one tool for an agency, I’d recommend Similarweb.

Similarweb Ad Intelligence

Why it fits your use case:

• Cross-channel: lets you investigate competitor activity across search, social, display, and video, rather than treating PPC and social as separate silos. www.similarweb.com
• Creative intelligence: you can inspect competitor ad creatives, messaging, formats, and performance signals. support.similarweb.com
• Landing-page intelligence: its Paid Landing Page Analyzer connects paid ads to the landing pages receiving traffic, with paid keywords, traffic share, and estimated spend. www.similarweb.com
• Agency-friendly: useful for turning competitive research into client-facing strategy—e.g. "here's what the top 5 competitors are running, where they're sending traffic, and what messaging they're emphasizing."

Two alternatives worth considering

Semrush — probably the better choice if your agency is search/PPC-heavy. Its Advertising Research gives you competitor keywords, live ad copy, historical activity, and associated landing pages; its broader toolkit now adds social/display intelligence through AdClarity. www.semrush.com

Adbeat — particularly strong if your agency cares about display/programmatic creative and landing-page intelligence. It emphasizes competitor creatives, publishers, landing pages, campaign monitoring, comparisons, and alerts, and explicitly markets to agencies. www.adbeat.com

My pick:

• Cross-channel search + social + landing pages → Similarweb
• Primarily Google/search → Semrush
• Primarily display/programmatic creative → Adbeat

If you tell me whether you're looking for Meta + Google specifically, I can narrow this down to the 2–3 best options for an agency and compare coverage, freshness, creative library, landing-page tracking, and pricing.

For an agency, I’d recommend Semrush Advertising Toolkit.

Why it fits your use case particularly well:

• Search ads: Advertising Research shows competitor paid keywords, ad copy, ad history, and competitors. www.semrush.com
• Landing pages: You can see which landing pages competitors are sending paid-search traffic to, including the URLs associated with individual ads. www.semrush.com
• Social/display: Its AdClarity component extends competitive intelligence into display, video, and social, with filters for geography, channel, device, etc. www.semrush.com
• Agency reporting: Data can be exported and incorporated into reports, which is useful if you're doing competitor intelligence for multiple clients. www.semrush.com

The caveat: If your priority is deep social creative intelligence—e.g., systematically cataloging Meta creative variants, seeing which concepts are running longest, and building a swipe-file-style creative library—I'd evaluate a dedicated social ad-intelligence platform alongside Semrush. Semrush is strongest as the search + landing-page + broader advertising intelligence hub.

If you tell me whether you're mainly working with Meta, Google, TikTok, LinkedIn, or all of them, I can narrow this down to the best 3 tools for an agency and compare coverage, pricing, and creative/landing-page depth.
