What is remarketing?
Remarketing is a form of advertising that targets people who have already interacted with your business (visited your website, used your app, or engaged with you) and shows them relevant ads to bring them back. Most people do not buy on their first visit, so remarketing follows up, reminding them of what they looked at and nudging them to return and convert. It is one of the highest-return tactics in digital advertising, because it targets people who already know you.
You may also see it called retargeting. The terms are used interchangeably, though “remarketing” is Google’s term and sometimes also refers to email follow-ups.
How does remarketing work?
- A visitor comes to your website but leaves without buying or enquiring.
- A tag or pixel (a small piece of code) adds them to a remarketing audience.
- They see your ads as they browse other websites, use social media, watch YouTube, or search Google.
- The ads bring them back to complete the action they did not finish.
You can target based on what they did, for example everyone who visited, people who viewed a product, or people who added to cart but did not buy.
Types of remarketing
- Standard / display remarketing: banner ads shown across the web (Google Display Network).
- Search remarketing (RLSA): adjusting your search ads for people who have visited before.
- Social remarketing: ads on Meta (Facebook and Instagram), TikTok, and others to past visitors.
- Video remarketing: ads on YouTube to people who engaged with your site or channel.
- Dynamic remarketing: ads that show the exact products or services someone viewed.
- Email remarketing: follow-up emails, such as abandoned-cart reminders.
Why remarketing works
- It targets warm audiences. These people already know you, so they convert at a higher rate than cold traffic.
- It is cost-effective. Higher conversion rates usually mean a lower cost per result.
- It recovers lost sales. Most visitors leave without buying; remarketing brings them back.
- It keeps you top of mind. Repeated, relevant exposure builds familiarity and trust.
- It works across the funnel, from reminding browsers to closing near-buyers.
Remarketing best practices
- Segment your audiences. Treat a cart-abandoner differently from a first-time visitor.
- Cap the frequency, so you remind people without annoying them.
- Use dynamic ads to show the exact products someone viewed.
- Exclude people who converted, so you stop paying to reach existing customers.
- Match the message to the stage, a gentle reminder for browsers, an offer for near-buyers.
- Set a sensible window, since interest fades over time.
