* If I search for recipes, the Google algorithm seems to heavily favour recipes with a short novel prepended to them. The “novel” does not have to be particularly relevant to the content - I’ve seen recipes with “novels” that I’m not convinced wasn’t partially algorithmically generated. Every human being I’ve ever spoken to hates this.
* Google will search for what it believes to be alternatives to terms, even when those terms are placed into quotes (which used to prevent this behaviour). This can be very irritating when Google’s alternative terms are incorrect.
Both of these are regressions over earlier behaviour, and don’t seem to have any obvious benefit to them.
