At this point I feel like it's that Search has gotten significantly worse. I've had pages of results that are completely AI-generated text, with my search query just rephrased as a sentence. As an employee, it's disappointing.
I find having to quote things more and more, to the point where all or almost all keywords are quoted. Lately, somehow, even that produces results that don't actually include everything that was quoted.
I also wonder why almost no web forums I use are coming up in results at all, despite their robots.txt allowing indexing. Feels like Google is becoming a bit like East Germany...
If Google is so large and so arrogant that they can't even take feedback from internal employees then it's probably game over for them. They certainly aren't listening to developers and power users on forums.
