No, you can absolutely use the same audience for other ads, even if you stop a campaign in Facebook Ads. When you pause or stop a campaign, the audience you created stays saved in your account, so you can reuse it anytime for future campaigns. Here’s how it works: Custom Audiences: If you built a custom audience (like website visitors or people who engaged with your posts), it’s still available for use in other campaigns. Just select it when creating a new ad set. Saved Audiences: If you used specific targeting criteria (like age, location, and interests) and saved the audience, you can access it again under "Saved Audiences." Lookalike Audiences: Lookalikes you’ve created will remain in your account, ready to be used for other campaigns. Stopping a campaign only halts the ads, not the audience itself. So feel free to use that same audience to test new creatives, objectives, or strategies without having to start from scratch!
