# Remarketing: check who is eligible before launch

Build a remarketing audience from a meaningful action. Check consent, exclusions, network eligibility and the difference between attribution and lift.

Remarketing reaches people who have already interacted with your business. Google Ads calls these audiences [your data segments](https://support.google.com/google-ads/answer/2497941). Start with a useful follow-up message and verify that the eligible audience can actually receive it.

## 1. Define one reason to return
Write an inclusion action, a membership window and an exclusion. Use a behaviour tied to the offer, such as viewing a product comparison, instead of assuming every visitor needs the same reminder. Choose a window that reflects the buying cycle. Exclude completed purchases when the message asks for the same first purchase; a separate repeat purchase offer needs its own logic.

## 2. Check the audience source and permission
Confirm which tag or connected property populates the segment. Test the matching URL or event on a real route with safe test data. Respect user choices and applicable platform policies; do not broaden collection to meet an audience minimum. Never put email addresses, phone numbers or other personal details in URL rules or tag parameters.

## 3. Compare eligible reach on the intended network
In Audience Manager, inspect the segment's status and size for the selected network. [Google's compatibility guidance](https://support.google.com/google-ads/answer/7476585?hl=en) explains that network, segment type and size can affect eligibility. Check the current status in the account rather than assuming a sitewide visitor count meets the requirement. Review [audience exclusions](https://support.google.com/google-ads/answer/2549058?hl=en) and verify whether the chosen campaign can expand beyond the segment. Do not describe delivery as remarketing-only if expansion is enabled.

## 4. Use this hypothetical launch review

| Check | Observation | Decision |
| --- | --- | --- |
| Web analytics | 900 visits to comparison pages | Not an eligible audience count |
| Audience Manager | Intended network shows too small | Do not launch this segment |
| Recent buyers | Purchase exclusion still being verified | Test it before spending |
| Message | Ad offers help choosing a plan | Send users to the relevant comparison |

If the segment is too small, wait or reconsider a genuinely related inclusion action. Do not remove necessary exclusions to make the numbers look bigger.

## 5. Separate attributed conversions from extra sales
Past visitors may already intend to buy. A reported conversion following an ad does not establish that the ad caused the purchase. Keep the comparison, attribution window and conversion definition stable. Use an appropriate holdout where feasible; with limited volume, report attribution and limitations. If delivery is weak even after eligibility is confirmed, check [budget and rank constraints](https://cpcinsider.com/insights/google-ads-impression-share/) where those metrics apply.
