Not update review may be google not show nagative review of product

Google uses a combination of machine learning and human moderators to moderate reviews on Google Maps.

Google Have created strict content policies to make sure reviews are based on real-world experiences and to keep irrelevant and offensive comments off of Google Business Profiles.

As soon as someone posts a review, google send it to their moderation system to make sure the review doesn’t violate any of their policies.

If google systems detect no policy violations, then the review can post within a matter of seconds. Their systems continue to analyze the contributed content and watch for questionable patterns. These patterns can be anything from a group of people leaving reviews on the same cluster of Business Profiles to a business or place receiving an unusually high number of 1 or 5-star reviews over a short period of time. The policy-violating content is either removed by their automated models or flagged for further review by trained operators and analysts who conduct content evaluations that might be difficult for algorithms to perform alone, because of that it may takes time to re-publish the content
