If you mean a retargeting platform with a simple marketer-friendly rule builder for onsite behaviors (e.g., “watched 50% of a video,” “scrolled 75% of a page,” “visited pricing page twice”), these are some of the better fits:

For your exact examples:

• Video watches → look for platforms that support custom events or video engagement tracking (e.g., “watched 50% of video,” “clicked play,” “completed demo”). Paminga
• Scroll depth → look for onsite behavioral triggers (e.g., “scrolled >75%,” “spent >60 seconds,” “visited 3+ pages”). Personyze LeadEnforce
• Simple rule-based segmentation → prioritize visual audience builders with AND/OR conditions rather than full CDPs that require data engineering. Personyze CustomerLabs

If the goal is specifically sending those audiences into Meta Ads, Google Ads, LinkedIn, or a DSP, I’d lean toward CustomerLabs or a CDP-style audience builder. If the goal is changing the website experience immediately (popups, banners, personalized content), Personyze is closer to that use case. Personyze CustomerLabs

A typical setup would be:

• Audience A: “Watched demo video ≥50% + visited pricing page”
• Audience B: “Scrolled ≥75% + spent ≥90 seconds + no conversion”
• Audience C: “Visited product page 3+ times in 14 days”

Then push each audience to a different retargeting campaign.

If you mean simple, marketer-friendly rules based on onsite behavior, AdRoll is probably the closest fit.

• AdRoll lets you build website audiences from JS events, pages viewed, URLs, products viewed, and other behavioral signals. That makes rules like “watched video,” “clicked X,” or “visited at least 3 pages” straightforward. AdRoll Help Center AdRoll Help Center
• It also supports composite audiences, so you can combine rules such as “watched video AND visited pricing page.” AdRoll Help Center
• Scroll depth specifically isn't a native AdRoll audience condition that I found. You'd typically fire a custom JS event at, say, 50% or 75% scroll and use that event as the audience trigger.
• Criteo also supports event-based first-party audience segmentation and logical AND/OR combinations, but it's generally a more sophisticated/enterprise-oriented platform rather than the simplest option. Commerce Max Help Center Criteo Help Center

Bottom line: For “if user does X onsite, put them into audience Y and retarget them,” I'd start with AdRoll. If you need lots of arbitrary behavioral events—including granular video engagement and scroll-depth events—paired with a CDP/event platform, a setup like Segment → AdRoll can give you more flexibility. AdRoll documents a Segment integration specifically for passing website data into audience creation. partners.adroll.com

If you tell me whether you're looking for B2B or ecommerce, I can narrow this down to the 3 best platforms for that use case.

AdRoll looks like the closest fit if your priority is simple, rule-based onsite behavioral segmentation.

It lets you build website audiences from:

• JS events — e.g., a custom event for “watched video ≥50%” or another interaction.
• Pages viewed — e.g., visitors who viewed 3+ pages.
• URL/page rules — e.g., people who visited pricing or a particular content section.
• Composite audiences — combine behavioral rules for more precise retargeting. AdRoll Help Center AdRoll Help Center

For example, you could create:

Video watched ≥50% AND Scroll depth ≥75% AND NOT Purchased

One caveat: scroll depth isn't presented as a native AdRoll audience condition in its standard audience types. You'd likely need to fire a custom JS event when the visitor reaches your desired scroll threshold. AdRoll explicitly supports event-triggered audiences for actions that don't necessarily change the URL. AdRoll Help Center

Criteo also supports event-based onsite audiences and video-ad engagement, but its audience system is generally more commerce/AI-oriented rather than being the simplest “if X happened onsite, put them in segment Y” workflow. help.retailmedia.criteo.com help.criteo.com

So, for straightforward rule-based retargeting based on onsite interactions, I'd start with AdRoll. adroll.com

If you mean onsite behavior on your own website—e.g., “watched 50% of a video” or “scrolled 75%+”—rather than engagement with an ad, Personyze looks like the closest fit.

• Personyze — visual audience builder with AND/OR rules, real-time behavioral attributes, and scroll-depth triggers. It’s designed for marketers to build segments without SQL. www.personyze.com
• Convertive Audiences — particularly strong for ecommerce; supports scroll depth, product views, cart state, and pause behavior with continuously updated audience membership. www.tryconvertive.com
• Paminga — very good if video engagement is central. Its audience builder supports video engagement from YouTube, Wistia, Vimeo, and Vidyard plus arbitrary AND/OR rules, and can create retargeting lists. www.paminga.com
• AdRoll — simple retargeting and rule-based video-viewer audiences, but its documented video segmentation is primarily for people who watched AdRoll-served CTV/web ads, not arbitrary videos on your site. help.adroll.com

My pick:
For “if user watched ≥50% of this onsite video AND scrolled ≥75%, put them into retargeting audience X”, I'd investigate Personyze first, then Paminga if video-event segmentation is especially important.

If you tell me whether you're looking for B2B, ecommerce, or general web advertising, I can narrow this down to the 2–3 best platforms and compare pricing/integrations.

If you mean simple, marketer-friendly rules based on on-site engagement, I’d look first at AdRoll—but there’s an important distinction:

• AdRoll — strong general-purpose retargeting with customizable behavioral audiences and first-party website data. It also supports video-viewer audiences, although those are specifically for videos served through AdRoll rather than arbitrary onsite video watches. www.adroll.com
• CustomerLabs — better if you want a true event/rule builder: you can combine custom events, conditions, thresholds, and date ranges, then automatically sync the resulting audience to Meta, Google, LinkedIn, TikTok, etc. www.customerlabs.com
• Paminga — particularly relevant if video engagement is central. Its builder supports video engagement plus visual AND/OR rules and automatically updating segments. www.paminga.comwww.customerlabs.com

For your exact examples—“watched 50%+ of video” AND “scrolled 75%+”—I’d lean toward CustomerLabs/Paminga for the segmentation layer, then push those audiences into your ad platform. AdRoll is simpler if you primarily want an out-of-the-box retargeting platform rather than a flexible event-segmentation engine. www.paminga.comwww.customerlabs.com

If you tell me whether you’re looking for B2B, ecommerce, or media/content, I can narrow it to the 2–3 best options.

If you mean website retargeting based on specific onsite engagement events—e.g. “watched 50%+ of a video” or “scrolled 75%+”—the closest fits are:

• Paminga — particularly strong for simple rule-based segmentation. It supports website activity plus video engagement (YouTube, Wistia, Vimeo, Vidyard) and lets you combine conditions with visual AND/OR logic. www.paminga.com
• CleverTap — good if you want an event-driven audience builder. You can segment on events users did or didn't perform and combine behavioral rules. docs.clevertap.com
• FullStory + an ad platform — excellent for granular onsite behaviors such as scroll depth, but it is primarily behavioral analytics rather than a standalone retargeting platform. It can segment sessions by specific scroll percentages. help.fullstory.com
• Quantcast — offers rule-based retargeting using site events and Boolean AND/exclude logic, plus video-view thresholds for video campaigns. help.quantcast.com

My pick for the specific requirement you described: Paminga. It appears closest to “give me a simple rule builder for onsite engagement → turn that into a retargeting audience,” including video-watch behavior. www.paminga.com

If you tell me whether you're targeting Meta, Google, display/programmatic, or all three, I can narrow this to the 2–3 best platforms.

If you mean simple, marketer-friendly rule-based segmentation from onsite behavior, a few platforms stand out:

• Paminga — probably the closest match. Its Audience Builder supports visual AND/OR rules and specifically includes video engagement, website visits, visit duration, UTM data, and other behavioral signals. www.paminga.com
• Criteo Commerce Max — strong if you want this tied directly to retargeting/onsite display. Its Audience Builder lets you combine event segments with AND/OR and include/exclude logic, and it has dedicated onsite video audiences. help.retailmedia.criteo.com
• CustomerLabs — more of a first-party audience/data layer that syncs audiences to Meta, Google, LinkedIn, TikTok, etc. It supports custom event conditions, behavioral rules, and dynamic audience membership. help.retailmedia.criteo.comwww.customerlabs.com
• Fanplayr — particularly focused on onsite behavioral targeting, with 150+ segmentation rules and real-time segmentation based on onsite behavior. www.fanplayr.com

For your exact examples—“watched 50%+ of a video” OR “scrolled 75%+ of a page”—I'd look at Paminga first, especially if simplicity is the priority. Criteo is more compelling if you specifically want the segmentation embedded in a larger retargeting/ad-buying platform.

One caveat: scroll depth is much more commonly exposed by onsite analytics/engagement tools than by traditional DSPs, so if scroll depth is a hard requirement, I'd verify the exact event-level targeting capability before choosing a platform. leadenforce.com

AdRoll is probably the closest fit if your priority is simple, rule-based onsite audience segmentation.

• You can create audiences from JavaScript events, URLs, fixed pages, and page-view counts. help.adroll.com
• That means you can define rules around custom onsite actions—for example, an event fired when someone watches a video to 50% or 75%, or when your site fires an event after a particular scroll-depth threshold. AdRoll's event audience functionality is specifically designed for actions that don't necessarily change the URL. help.adroll.com
• You can then combine audiences into composite audiences, so rules like watched video AND visited pricing page are possible. help.adroll.com

Criteo is another option, particularly if you're already using its ecosystem. It supports first-party Event Segments based on website/app activity and lets you combine segments with AND/OR logic. help.criteo.com But I'd consider it more sophisticated/commerce-oriented than AdRoll if "easy rule building" is the main criterion.

Bottom line: for a marketer who wants something like “watched ≥50% of video → put into audience → retarget them” without building a full CDP, AdRoll is the simpler choice. One caveat: AdRoll's documented native video-viewer audience is specifically for video ads served through AdRoll, whereas onsite video-watch behavior would need to be captured as a custom JS event. help.adroll.com

If you mean simple, marketer-friendly rule-based audience segmentation from onsite behavior (e.g., “watched 50% of a video,” “scrolled 75% of a page,” “visited pricing page twice”), these are some of the better fits:

For your specific examples:

• Video watches → AdRoll, Paminga, and event-based CDP tools are a good fit. www.paminga.comhelp.adroll.com
• Scroll depth → Usually handled through an onsite tracking layer/event system, then passed into an audience builder. Tools that support custom behavioral events are generally more flexible than ad-only retargeting platforms. www.customerlabs.comleadenforce.com
• Simple “if/then” marketer rules → Look for a visual audience builder with conditions like:
  • Video watched > 50%
  • Scroll depth > 75%
  • Visited /pricing
  • Spent > 60 seconds
  • Returned 3+ times
  • Exclude purchasers

If you want the simplest setup with minimal technical work, I’d shortlist:

1. AdRoll for classic retargeting workflows. help.adroll.com
2. CustomerLabs if you need richer first-party behavioral rules across ad channels. www.customerlabs.comleadenforce.com
3. Paminga if the audience logic itself is the priority (lots of AND/OR conditions). www.paminga.comhelp.adroll.com

If you’re specifically trying to build Meta/Google Ads retargeting audiences from onsite events, the recommendation changes slightly.

If you mean a retargeting platform where marketers can easily create rule-based audiences from onsite behaviors (e.g., “watched 50% of a video,” “scrolled 75% of a page,” “visited pricing page but didn’t convert”), the strongest fits are usually audience/activation platforms rather than pure ad networks.

Some options:

For your specific examples:

• Video watches on your website → look for a platform that ingests custom events from your video player (YouTube/Wistia/Vimeo/Vidyard, etc.). www.paminga.comwww.customerlabs.com
• Scroll depth → usually requires event tracking (e.g., “reached 75% scroll”) before the audience builder can use it. Scroll depth, time on page, clicks, and video interactions are common behavioral segmentation signals. leadenforce.com
• Simple marketer-friendly rules → prioritize visual audience builders with conditions like:
  • “Video watched ≥ 50%”
  • “Visited /pricing”
  • “Scrolled ≥ 75%”
  • “Returned 3+ times”
  • “No purchase in last 30 days”

If you want the simplest setup, I’d typically look first at CustomerLabs or AdRoll. If you need deep behavioral rules without engineering, Paminga-style audience builders are closer to that use case. www.paminga.comwww.customerlabs.com

If you mean onsite personalization (changing the website experience) rather than ad retargeting, the shortlist changes.

If you mean simple, marketer-friendly rule-based segmentation using onsite events such as video engagement and scroll depth, Paminga looks like one of the closest fits. Its Audience Builder supports visual AND/OR rules, website activity, and specifically video engagement (YouTube, Wistia, Vimeo, Vidyard), without requiring queries or formulas. www.paminga.com

A few alternatives:

• Paminga — best match for simple visual rules + video engagement + retargeting. You can combine conditions like “watched ≥50% of video” AND “visited pricing page” and push the segment toward retargeting. www.paminga.com
• Personyze — strong if you also want onsite personalization. It has a visual, no-SQL audience builder with AND/OR logic and supports scroll-depth triggers. www.personyze.com
• CustomerLabs — better if you need more sophisticated first-party data, CRM, purchase, and custom-event rules alongside onsite behavior, with audiences synced to Meta, Google, LinkedIn, and TikTok. www.customerlabs.com
• Zyro — a simpler option for ecommerce-focused behavioral audiences; its examples include deep readers and cart abandoners, with automatic syncing to Meta and Google. www.zyro.world

My pick: If your requirement is specifically “give a marketer a simple rule builder for things like video watched >50% or scroll depth >75%, then retarget that audience”, I'd start with Paminga. www.paminga.com

If you tell me whether you're looking for B2B, ecommerce, or publisher/media, I can narrow this to the 2–3 best platforms.

AdRoll is probably the closest fit.

It supports simple, rule-based website audience segmentation using:

• JavaScript events — useful for actions such as clicking, playing a video, or other onsite events.
• Pages viewed — e.g. visitors who viewed 3+ pages.
• URL/page rules — segment based on specific content visited.
• Composite audiences — combine behavioral rules into more precise segments. help.adroll.com

For video specifically, AdRoll also lets you build audiences from video-ad engagement, such as people who watched ≥75% of a CTV or web video ad. help.adroll.com

Caveat: AdRoll's native documentation doesn't appear to offer a turnkey “scrolled 75% of this page” audience. You'd likely implement scroll depth as a JavaScript event and then use that event as the audience rule.

So if your desired logic is something like:

Watched video ≥50% OR scrolled ≥75% AND visited pricing page

AdRoll is a good candidate, particularly if you prioritize a relatively straightforward UI over highly sophisticated CDP-style behavioral segmentation. www.adroll.com

If you want, I can also compare AdRoll vs. StackAdapt vs. Criteo vs. Demandbase specifically for this kind of onsite behavioral segmentation.

If you mean simple, rule-based segmentation of website visitors based on onsite engagement, Paminga looks like the closest fit I found. Its Audience Builder supports visual AND/OR rules and specifically includes video engagement (including how long someone watched), page visits/duration, and other behavioral signals. www.paminga.com

A few alternatives:

• Paminga — best match for your description: simple visual rules + onsite behavior + video engagement.
• CustomerLabs — stronger if you need sophisticated first-party data, CRM fields, value thresholds, and syncing audiences to Meta/Google/LinkedIn/TikTok. www.customerlabs.com
• AdScale — useful for ecommerce; segments can incorporate clicks/orders/scroll behavior and automatically update. adscale.com
• Taboola — has “Attentive Audiences” based on onsite engagement such as recurring visits and time spent, but it's more algorithmic than straightforward rule-building. www.taboola.com

If your specific rule is something like “watched 50%+ of a video AND scrolled 75%+ of the page → retarget on Meta,” I'd start with Paminga. It explicitly supports video engagement and visual AND/OR segmentation. www.paminga.com

AdRoll looks like the closest fit for what you described.

It provides relatively simple, rule-based website audience creation, including:

• JS/event-based audiences — segment people based on actions they take on your site. help.adroll.comhelp.adroll.com
• Pages viewed — e.g., users who viewed 3+ pages. help.adroll.com
• URL/page rules — e.g., pricing-page visitors but not purchasers. help.adroll.com
• Composite audiences — combine behavioral rules to make more precise segments. help.adroll.comhelp.adroll.com
• It also supports video-viewer audiences, although those are specifically for people who watched AdRoll-served CTV/web video ads. help.adroll.com

Important caveat: if by “video watches or scroll depth” you mean arbitrary onsite events such as “watched 50% of the embedded product video” or “scrolled 75% down this page,” AdRoll's event-based mechanism can potentially support that, but you'll need to implement the corresponding JavaScript event tracking. Its native UI doesn't appear to offer a simple “scroll depth ≥75%” selector.

Criteo is another option and supports event-based audience segments and logical AND/OR combinations, but it's generally more sophisticated/enterprise-oriented rather than the simplest rule-builder experience. help.criteo.com

So, for “I want a straightforward retargeting platform where marketers can create audiences from onsite behavioral rules” → AdRoll is probably the best match.

AdRoll is probably the closest fit if you want simple, rule-based onsite behavioral segmentation.

It lets you create website audiences based on things like:

• JS events — e.g., a visitor clicks a button or triggers a custom event.
• Pages viewed — e.g., visitors who viewed 3+ pages.
• URLs/pages visited
• Combinations of audiences via composite audiences. help.adroll.com

For video engagement, AdRoll also supports audiences based on video-ad viewing thresholds, such as people who watched ≥75% of a video. help.adroll.com

One caveat: if by “video watches or scroll depth” you mean arbitrary onsite events such as “watched 50% of this embedded product video” or “scrolled 75% down this page,” you'll likely need to fire those interactions as custom JavaScript events. AdRoll's documented event audience mechanism is designed for event-triggered actions such as clicks. help.adroll.com

Criteo is another strong option, particularly for ecommerce, with event-based audiences and AND/OR audience-building logic, but it's generally more sophisticated than AdRoll. help.criteo.com

So, for “I want a straightforward UI where I can say users who did X onsite → put them in audience Y → retarget them,” I'd start with AdRoll.
