I don't care about the ads, but the results themselves have gone to **** over the past year or so. In fact, other than for work reasons, the only time I use Google is when I specifically want the ads. And frankly, even the ads are likely to be irrelevant these days. Google's ads are selected more by user history than contextual or search relevancy these days, so the ads are more likely to be for something I searched for three weeks ago than for something I'm looking for now.
But at least there's a chance that the ads may be relevant if you use a virgin browser, on a brand-new machine account, from behind a proxy server, on a wired connection, with all forms of geolocation disabled. If you can completely hide your identity, location, and history, then maybe you'll get a contextually relevant ad -- once. After that, all bets are off.
The actual search results are also useless most of the time. They've worked so hard to try to thwart SEO that they've wound up hosing relevancy in the process. Add to that the fact that the algos now factor user history into the SERP, and the results become a steaming, festering pile of irrelevant ****.
I get particularly annoyed when Google includes results that don't include one or more of the words or terms searched for, with the word "Missing" and strikeovers through the term(s) appearing under the result. If the term is "missing," then why the hell return the result? Do their algos assume that the user included the "missing" term for the sheer joy of typing it into the search box, rather than because it was relevant to the search? So then the user has to try "Verbatim," quotes, brackets, etc. to try to persuade Google to actually return the results for the terms searched on, rather than what it thinks the user really meant to search on if the user weren't such a dolt.
I wish there were a search engine that simply returned the results for exactly what I searched on, even if the terms are misspelled or otherwise don't make sense to the search engine. I don't want spelling corrections, stemming, synonyms, or any of that ****. Kindly return the results for exactly the terms I searched on, thank you, and leave it at that.
