Also goes by Remarketing [![Siite](/images/layout/logo.svg)Written by Siite](/about/)Updated September 8, 2026 ## Entry contents [All Terms A to Z←Browse the full dictionary](/dictionary/) Retargeting shows ads to people who have already interacted with you: visited a page, watched a video, opened an email, or appear on a customer list you uploaded. The audience is small and warm, which is why the click and conversion rates look flattering next to cold campaigns. It is a recovery channel, not a demand channel. > **Briefly explained** > > - Ads aimed at people who already came to you once. > - Best suited to decisions that take days, not minutes. > - Cheap relative to the value of the job it recovers. > - Capped badly, it reads as surveillance rather than a reminder. ## How are the audiences built? The sources, in descending order of how far you can rely on them: - **Your own customer list**, uploaded and matched. The most durable, and the least affected by browser changes. See [first-party data](/dictionary/first-party-data/). - **Site visitors**, collected by a tag. Smaller and shorter-lived than they used to be. - **Engagement on a platform** — video views, profile visits, form opens. Held by the platform rather than by you. ## What can it realistically do? Recover decisions that are still open. The natural fit is the quote that has not been accepted yet. Someone weighing a large purchase thinks for days or weeks, talks it over with somebody else, and compares two or three prices. Staying visible during that window costs very little against the value of the work. What it cannot do is create demand. Nobody books a job they were not already considering because an ad followed them around. ## How do you run it without irritating people? - **Cap the frequency**, so the same person sees it a handful of times, not dozens. - **Keep membership short.** Two weeks suits most considered purchases. - **Exclude anyone who already booked.** Being chased after paying is the fastest way to look careless. - **Segment by what they looked at**, so the ad matches the job rather than the brand. - **Keep the budget modest.** It is a supporting channel. Treating it as a main one inflates its apparent performance. ## Why does it look better than it is? Because this audience arrived pre-qualified by their own earlier visit. A share of these people would have come back anyway, and the platform counts them as recovered. Read it with that in mind. The honest question is not what it converted, but what it converted that the rest of your marketing would have lost. ## What do the terms mean? - **Audience:** The list of people the ads can reach. - **Membership duration:** The length of time a visit keeps somebody in the audience. - **Frequency cap:** A ceiling on how many times the same person is shown it. - **Exclusion audience:** A list the campaign must not show to, usually existing customers. - **View-through conversion:** Credit claimed for someone who saw the ad without clicking. Treat it with suspicion. Owner questions ## What owners ask us about Retargeting ### Does retargeting work for emergency work? +Barely. Someone with water on the floor hires within the hour. It works for planned, high-ticket decisions: replacements, remodels, anything quoted and considered. ### Why do people see the same ad for weeks? +Because nobody set a frequency cap or a membership duration. Both should be short enough that the ad reads as a reminder rather than as surveillance. ### Is retargeting still possible with the privacy changes? +Yes, but audiences are smaller and shorter-lived than they were. First-party lists from your own CRM have become the more reliable input. ### How small is too small an audience? +Platforms enforce a minimum before a list can be used, and well above that minimum the targeting is still thin. If your site gets few visitors, this channel is not where your next job comes from. ### Should I exclude people who already bought? +Always. Nothing looks worse than being chased by an ad for something you already paid for, and it wastes the budget on the one group guaranteed not to convert.Put this to work ## Guides that use this Step-by-step playbooks from the team, written for owners doing the work themselves.
