What is Remarketing (Retargeting)?
Remarketing shows ads to people who have already interacted with your site, app, or videos, on Search, Display, YouTube, or Shopping. It re-engages warm audiences who didn't convert the first time. On Search specifically, RLSA (Remarketing Lists for Search Ads) lets you adjust bids or keywords for past visitors who search again.
What to know in practice
- Remarketing audiences convert at higher rates than cold traffic but at lower volume; treat it as a closer, not a prospecting engine.
- Segment by intent: cart abandoners and pricing-page viewers deserve different messaging and bids than homepage bouncers.
- Frequency capping matters, the same ad shown too often shifts from helpful reminder to annoyance and brand damage.
- Privacy changes (cookie deprecation, consent requirements) have shrunk addressable remarketing audiences; first-party data and Customer Match are increasingly important complements.
Common misconception
Remarketing's high conversion rate doesn't mean it caused those conversions, many of those users would have returned anyway. Measure incremental lift, not just last-click conversions, before scaling spend.
