Retargeting and Cookie Pools

Retargeting reaches past visitors who didn't convert. Highest-ROI ad type. Build cookie pool through site visits + email engagement.

Cookie pool sources

1. Site visitors — Meta Pixel, Google Tag
2. Engaged users — time-on-page, scroll depth
3. Cart abandoners — added but didn't purchase
4. Email subscribers — engaged readers
5. Free trial users — didn't convert
6. Past customers — for upsell
7. Lookalikes — built from existing pools

Retargeting strategies

1. Direct retargeting — past visitors with discount
2. Sequential retargeting — different ad based on funnel stage
3. Dynamic product ads — show product viewed
4. Look-alike scaling — extend pool to similar users
5. Frequency capping — limit ad exposure (avoid fatigue)

Typical retargeting ROAS 3-10× vs cold acquisition 1-3×.

Tracking setup

1. Install Meta Pixel + Google Tag Manager
2. Track key events (page view, add-to-cart, signup, purchase)
3. Create custom audiences in each platform
4. Sync to ad campaigns
5. Monitor cookie pool size + freshness
6. Refresh creative every 2-4 weeks (combat ad fatigue)
