I once wrote a negative review of a business on Google, and it went up, but when I went to look at the business's reviews under my wife's Google account, it was not there. I waited an hour and checked. Then a couple hours and checked. Then a day. It never showed up. I posted the review under her account and did the same checks for my account. It never showed up. I do not know why it didn't show up, but I wouldn't be…
You can not pay to change Google reviews. Period. And the theories of "you dont know whats happening in all parts" is not true because I looked at detailed numbers myself and other than legal processes, everything was clearly visible.
If anything Google has a clearly different org and we often told very highly paying customers that even if they were paying us hundreds of millions a year that does not change our policies. One of the luxuries of being Google scale I guess.
Google gets a lot of (potentially justified) criticism on Hackernews but this conspiracy that Google lets businesses pay for reviews is plain stupid.
