Putting ads near a floating action button can work, but you gotta be careful. The FAB grabs attention since people use it a lot—like for chatting, adding stuff, or taking quick actions—so dropping an ad nearby might get it noticed more. But if the ad gets in the way or makes things feel messy, it could just annoy people. Nobody likes a cluttered screen. The trick is to keep things chill—make sure the ad's easy to spot but not super in-your-face. Try different spots and see what clicks (literally). At the end of the day, you want people to have a smooth experience, not feel like you're spamming them with ads.
