I suspect that this is the direct result of AI generated content just overwhelming any real content.
I tried ddg, google, bing, quant, and none of them really help me find information I want these days.
Perplexity seems to work but I don’t like the idea of AI giving me “facts” since they are mostly based on other AI posts
ETA: someone suggested SearXNG and after using it a bit it seems to be much better compared to ddg and the rest.
SEO spam has been a problem for a long time, but AI has allowed it to be accelerated to a whole new level.
