Yes, it’s possible to launch a Brand Lift even if your campaign is already over. However, there are a few guidelines to follow. Ideally, you should launch your Brand Lift once your campaign reaches around 70% completion. But sometimes, you might receive a late request to run a Brand Lift. In that case, we can still proceed, but keep in mind that: * We recommend not launching a Brand Lift **if the campaign ended more than one month ago**. Beyond that, ad recall tends to be too diluted to generate meaningful insights. * As always, you need to have reached **100,000 unique impressions** to run the Brand Lift. * It will take **longer to collect responses** and to obtain a full report. And that’s it!\ :wave: If you don't find your answer, feel free to reach out to for further consideration ! ### 🚀 Related articles * [Who are our respondents?](/methodology/happydemics-respondents/who-are-our-respondents.md) * [The set-up](/launch/the-set-up.md) * [What do I need to launch a Brand lift?](/launch/before-the-set-up/what-do-i-need-to-launch-a-brand-lift.md)
