For me with Firefox/uBlock: none. With chrome without blocker I had one at the top, one in the middle blocking scrolling, one at the bottom in a kinda static bar that can't be removed and one subscribe popup. Pretty nasty but not 7. I guess it depends on your location. But blockers are very effective on it.

Ps I mainly use local AI anyway especially when I put sensitive data in it. I use cloud AI mostly for deep research and there I'm just asking about things I don't know yet so it's not really privacy invasive.
