None, crowdsourced reviews are shit
I wouldn't be surprised if this question is from G's product/marketing team and we're giving them free "opposition research."
Blind > Google & Yelp combined 😁 :P
A while back we hired a team to scour the darkweb and try to buy fake reviews Fake Google reviews were about 5-10x cheaper than fake yelp reviews Also, all of the fake yelp reviews that were bought immediately got flagged as spam
how do they even flag it?
@apple mostly machine learning + heuristics on a bunch of metrics Source: used to be at Yelp
In a way the two review systems can complement each other. One time I found an Apple repair shop that got nothing but raves on Google. Then I go over to Yelp and discover 30-40% of his positives, an extraordinary high number, were filtered out by Yelp's automation leaving a lot of mediocre reviews in place. I concluded the business is probably not reliable or honest.
Google reviews can be gamed. I sometimes see positive reviews from shills from fly-by-night google accounts or friends of the business owner... sometimes I see the owner himself posting a review lauding his own business to inflate the Google review ratings. Yelp has automation to filter out spurious reviews. Yelp would rather throw out a few true positives and true negatives along with the false positives and false negatives; whereas Google accepts anything that anyone with a Google account can post, and as a result generally you will see misleadingly higher ratings.
