Flockr cohorts become audiences in Meta, Google, TikTok, and Pinterest — for retargeting at the moment demand is highest, seeding lookalike acquisition from your most signal-responsive shoppers, or excluding visitors who don't need to see the ad. Two integration paths cover identified and anonymous traffic.
Ad platforms let advertisers target audiences they've defined themselves. Upload a list of customer email hashes and the platform matches them against its signed-in user base. Drop a tracking tag with custom parameters and the platform builds an audience from cookied browsers.
Either way, the audience becomes targetable across that platform's ad inventory: search, display, social feed, video. Flockr cohorts are exactly the kind of audience these platforms expect.
Seed acquisition. Retarget directly. Exclude where you'd otherwise waste impressions. The three patterns paid media teams already think in.
Flockr produces cohorts that paid platforms can't generate on their own — visitors who responded to scarcity messaging, shoppers who gravitate toward surging-momentum products, customers whose purchases cluster around demand peaks. Use these as Customer Match seeds for Performance Max, Advantage+, and lookalike audiences.
scarcity_tipped_purchaser cohort becomes a Customer Match list. Google's algorithm finds new shoppers with similar behavioural fingerprints.Cohorts you'd build for email work for paid too. Cart abandonment with low-stock urgency. High-intent non-converters from the past 14 days. Browse abandonment in specific categories. The same cohort definition activates on both channels.
Negative targeting matters as much as positive. Don't pay to acquire visitors who already converted. Don't waste impressions on visitors who convert without help. Don't run brand awareness ads at customers in active retention flows.
recent_purchaser and scarcity_tipped_purchaser from broad acquisition campaigns. Lower spend, better ROAS.Ad platforms accept audiences in two shapes. Hashed customer data — email or phone — for matching against signed-in users. Or anonymous browser cookies, identified by the platform's own tag. Flockr supports both, because most cohorts have meaningful populations of each.
Hashed customer data, matched against the platform's signed-in users. Flockr cohort exports to your warehouse. Your team joins it to known emails and pushes the hashed list to the ad platform via reverse-ETL — Hightouch, Census, your CDP, or your own pipeline. The platform matches against its signed-in user base; matched users become a targetable audience.
Cookied browsers, identified by the platform's own tag. Flockr's bundle response carries cohort membership for the visitor. Your existing ad-platform tag fires a custom event with the cohort ID as a parameter. The ad platform builds an audience from cookied browsers. No PII at any point.
Most cohorts route to both paths. Path A reaches the identified shopper later in the funnel; Path B catches them earlier in-session. Customer Match seeds Performance Max; custom parameters fire the Display retargeting that runs the day after.
Five featured ad platforms, plus a long tail of smaller channels covered by the same warehouse-export-plus-reverse-ETL pattern.
Custom Audiences for Facebook, Instagram, Messenger, and Audience Network. Flockr cohorts become seed audiences for Advantage+ campaigns and direct retargeting audiences for traffic and conversion campaigns.
Customer Match across Search, YouTube, Display, Gmail, and Shopping. Flockr cohorts seed Performance Max audience signals and feed RLSA bid modifiers on Search.
Customer File Custom Audiences and lookalikes for TikTok Ads Manager. Flockr cohorts work as seeds for Smart Targeting and direct retargeting audiences.
Customer Lists and Actalike audiences for Pinterest Ads. Particularly suited to visual-product retailers — fashion, home, beauty — where Pinterest's search-and-discovery model aligns with demand intelligence.
Snapchat Customer List Audiences and Microsoft Advertising Customer Match. Smaller-volume channels for most retailers but covered by the same warehouse export plus reverse-ETL pattern as the larger platforms.
Most ad platforms accept hashed customer lists via reverse-ETL tooling like Hightouch and Census, which read directly from Flockr's warehouse exports.

A retailer wants to grow new-customer acquisition through Performance Max — Google's AI-driven cross-channel campaign type. The algorithm needs a high-quality audience seed to learn from quickly. Flockr's scarcity_tipped_purchaser cohort — customers who completed a purchase after a Flockr scarcity message was visible — is the seed.
The cohort starts empty. As shoppers complete purchases with a Flockr scarcity message visible at the click that converted, they enter the cohort. After a week, ~1,200 customers are in.
Flockr exports the cohort to the customer's warehouse. Hightouch syncs the joined hashed-email list to Google Customer Match. After 48 hours of matching, ~700 active users are in the audience.
The Customer Match list is added as an audience signal to a new Performance Max acquisition campaign. Google's algorithm uses the seed to find new shoppers with similar behavioural fingerprints.
The campaign converts. New customers enter the funnel; some end up in the same cohort themselves; the cohort grows; the seed gets stronger; the algorithm gets sharper. The loop is closed.
Customer Match seeded by demand intelligence consistently outperforms generic CRM-list seeds. The cohort definition isn't "everyone who bought" — it's "everyone who responded to demand context", which is what the algorithm is actually trying to find more of.
Shopify Audiences (Plus, US/CA only) is Shopify's own audience-building system. It generates custom audiences from cross-merchant Shopify data using machine learning, then pushes them to Meta, Google, TikTok, Pinterest, Snapchat, and Criteo. It does not accept third-party audience pushes — a Flockr cohort cannot be sent to Shopify Audiences for fanout to ad platforms.
Shopify Audiences and Flockr cohorts complement each other rather than compete. Shopify Audiences handles broad ML-driven retargeting from cross-merchant signals. Flockr cohorts handle precise demand-signal-driven targeting that the ML can't generate on its own. Plus merchants typically run both — Shopify Audiences for the wide net, Flockr for the specific cohort definitions that matter for their store.
