I can include site: to search a specific reviewer or Reddit, but that basically turns google into a local search. Has the time of google for product reviews now past? Is there a replacement that downranks these terrible SEO’ed fake recommendations?
Affiliate marketing and SEO optimization have pretty much destroyed the usefulness of searching for product reviews.
I usually just add "reddit" to the end of whatever I'm searching. It's the only way to read what real, mostly-unincentivized people think about something.
I wish Google had a way to "downvote" results. Sure they would have to mitigate artificial manipulation, but what they have currently doesn't work well.
For technical questions, they prioritize official documentation and SO. They don't serve you all those copy-pasta blogs that plague Google results.
For product reviews, they prioritize reddit and other forums by default. It's still far from perfect, but at least they're trying.
Google automated ranking, using totally random pagerank algos, which was their downfall. Reddit and youtube, in general, rely on crowdsourced ranking, which is harder to game (not impossible).
In Germany, there is test.de which is funded by its subscribers. They tend to do pretty objective reviews (but in German).
I'm no apologist for Google but I'd be willing to bet that if you wrote such a list and it was truly authoritative and unbiased then it would be very easy to find.
Search engines are pretty useless these days - any answer I'm looking for regarding anything is not found and instead I get AI/bot pulling non-answers/keyword driven paragraphs into a click seeking website.
At some point what could have been a great tool was taken over by capitalism and adtech. It's a shame.
