Over the past year to 1.5 years, in the sites I run, I have seen a drop in traffic from Google, which leveled off, and is now slightly rising.
I think if you look through this thread you’ll see a lot of skepticism of the AI results, and I think that is a fairly broadly held opinion. The obvious way to check the AI answer is to click through to some sources.
I think for Google to stop sending me traffic, it would have to be essentially perfect at AI answers. It will never get there, especially as so many searches are opinion-based like “what is the best mobile phone right now.”
