● The short answer
Retargeting shows ads to people who already visited your website, used your app or engaged with your content, reminding them to come back. It still works, especially for considered purchases, events and repeat business. Privacy changes have shrunk audiences, so it now leans more on first-party data and consent. Measure it carefully, because it often takes credit for sales that would have happened anyway.
Key takeaways
- Retargeting shows ads to people who already interacted with your site, app or content.
- Privacy tools, consent requirements and browser restrictions have shrunk retargeting audiences.
- Google said in April 2025 it would not add a new standalone third-party cookie prompt in Chrome.
How retargeting works
Retargeting (Google calls it remarketing) builds audiences from people who have already interacted with you, then shows them ads elsewhere. Common audience sources:
- Website visitors, tracked with an ad platform tag (Google tag, Meta pixel, LinkedIn Insight Tag, TikTok pixel).
- Customer lists you upload, such as emails of past buyers, where the platform matches them to its users.
- Video viewers and social engagers on YouTube, Instagram and other networks.
- App users for businesses with an app.
You can segment by behavior: people who viewed a pricing page, started a booking and left, or bought six months ago. Each segment gets a different message.

Is retargeting creepy?
It can be if it is overdone. Seeing the same ad 30 times after one visit feels intrusive. Keep frequency low, use reasonable time windows, stop showing ads to people who already bought, and be transparent in your privacy policy. Done with restraint, most people experience it as a reminder rather than surveillance.
How big does my audience need to be to retarget?
Platforms set minimum list sizes for ads to serve, and small sites can take a while to reach them. Google, Meta and LinkedIn each have their own thresholds, which change over time. If your site traffic is low, focus on growing traffic and building an email list first; retargeting a handful of visitors will barely deliver.
