Retargeting, sometimes called remarketing, is a digital advertising technique that shows ads to people who have already interacted with a brand, whether by visiting a website, viewing a product, or engaging with an app. Because these audiences already have some familiarity with the brand, retargeting campaigns often achieve stronger performance than campaigns targeting entirely new audiences.

How Retargeting Works

Retargeting relies on tracking technology, typically a small snippet of code placed on a website, that allows advertisers to build a list of visitors and later show them ads as they browse other sites or platforms. More advanced setups can segment audiences based on specific actions, such as visiting a product page without completing a purchase.

Common Retargeting Use Cases

• Reminding shoppers about items left in an online cart.
• Encouraging visitors who read a blog post to explore related products.
• Re-engaging past customers with new offers or products.
• Following up with leads who filled out a form but didn’t convert further.

Balancing Frequency and Relevance

While retargeting can be highly effective, showing the same ad too frequently can feel intrusive and lead to negative brand perception. Setting appropriate frequency caps and rotating creative helps keep retargeting campaigns feeling relevant rather than repetitive.

Privacy Considerations

As privacy regulations and browser policies continue to evolve, the tracking methods that power traditional retargeting are changing. Many advertisers are shifting toward first-party data strategies, such as building audiences from email subscribers or logged-in users, to maintain effective retargeting capabilities while respecting user privacy.
