Search engines look at a lot of different variables when evaluating business reviews for rankings. Here is a list of the most important factors that you should be concerned about:
Review Recency: One of the first things a search engine crawler will notice is review recency. Reviews from recent dates are favored more than old reviews as they are indicative that the business is still operational and is doing a great job of pleasing its customers.
Older reviews still have value but if your business stops receiving reviews on recent dates, that might create an issue. Make sure you keep getting reviews at a decent pace.
Review Format: The format of the review is also crucial. Star ratings are by far the best review format for search engines. This is because search engine crawlers can crawl and understand these ratings easily.
Google, for instance, uses review snippet structured data to find valid reviews. Based on the validity of the review, Google decides to include star ratings and review summary in SERPs.
Your target audience, on the other hand, might be more interested in video reviews with or without ratings. That’s a different story. When you are interested in improving local SEO for your online business, give due importance to the review format and make sure it includes star ratings with text.
Text alone or star ratings alone won’t be of much help.
Review Diversity: Reviews on multiple platforms also play a key role in local SEO. More diverse your reviews are, the better. It gives search engines review signals from multiple platforms and review sites, and this establishes authority.
Review Authority: Not all reviews are treated equally. Reviews from established and well-known people such as local guides might carry more weight as compared to a review from a new account.
Similarly, you must have reviews on different platforms. Having hundreds of reviews on Google Maps alone might not be as helpful as compared to reviews across different platforms.
Your business should have reviews from all types of people across all platforms.
Review Velocity: It is different from review recency. It looks at the consistency of getting new reviews. Getting the bulk of reviews in a day or two and then completely dead for a month raises a red flag.
The review velocity should be consistent across all the platforms. A big gap or having multiple reviews at once aren’t nice signals.
