Retargeting

Retargeting keeps your brand visible to users who have already shown interest but did not convert. By placing a tracking pixel on your site, you build an audience of past visitors and serve them ads as they browse other websites and apps. This leverages the principle that users who are already familiar with your product are more likely to convert than cold audiences.

For growth teams, retargeting typically delivers the highest ROAS of any paid channel because it targets users with demonstrated intent. AI enhances retargeting through dynamic creative optimization, which automatically shows users the specific products they viewed, and through predictive models that estimate recency-weighted conversion probability. Growth engineers should build segmented retargeting strategies rather than treating all past visitors the same. Users who abandoned checkout need different messaging than those who only viewed the homepage. Frequency capping is essential to prevent ad fatigue, and burn pixels should exclude users who have already converted. The most sophisticated teams use incremental lift testing to measure true retargeting impact, separating users who would have returned organically from those genuinely influenced by the ads.
