Do Product Ratings or Reviews Improve Google Rankings?

[rigelcable]

The is a lot of info on the web about how business reviews/ratings improve local search result rankings. However do product ratings or reviews improve PDP/PLP/Homepage (not local) rankings?

It's more of a user-friendly snippet then it does anything to your (local) SEO.

Although I have seen no evidence or documentation that local GMB listing reviews have any impact on non-localized search results for a brand's non-local homepage.

However, the picking apart of each little ranking algorithm factor is short-sighted. These things do not work in a vacuum. I have a client with a single location who does mostly eCommerce. But they allow people to come into the warehouse and buy directly if they happen to be in the area. This means we can get a GMB listing, and reviews for the location. I fully support this strategy, even if it doesn't help the homepage rank better.
