My experience is that search engines are still decent at finding niche information that would normally be hard to find. But for anything mainstream, for instance any household product that should be easy to find information about, instead how about these 300 pages of top 10 lists of Amazon affiliate links buried under AI generated filler?
I often have the opposite experience when looking for technical documentation about programming libraries. For example I will be dealing with a particular bug and will google the library name plus some descriptive terms related to the bug, and I get back general information about the library. In those cases, it seems google often ignores the supplemental information and focuses only on the library name as If I were looking for general information.
What is worse is that the top results are always blog-spam companies that just seem to be copying the documentation pages of whatever language or library I was looking at.
