Stay away from posting reviews using accounts that are linked to the business. If you are the owner or manager of the Google My Business account, Google’s AI will probably pick up on the post before it is ever seen. If not, it will probably be flagged shortly.
In the past, countless businesses have benefited from paid reviews that boost their rating, SEO, and overall customer traffic, but Google hates fake reviews. The intelligence that has been applied to the search engine is starting to pick up on accounts that post for specific businesses, flagging the review and potentially the account itself.
