Generally no. Google states it has a zero-tolerance policy for fake reviews. However, BrightLocal found that 62 percent of consumers believe they have seen a fake review in the last year. If you're unsure about the legitimacy of a review, check the username and avatar of the reviewer to see if anything is suspicious. You can also look at previous reviews the reviewer has made.
Pay attention to the date, time, and location of past reviews. If you see a reviewer has left reviews in cities across the world in a matter of days, that's a red flag. If the reviewer has never left another review, that's also something to take note of. If you believe a review is fake and in violation of Google's policies, you can request a removal from Google.
