Local Reviews don`t help Web Search results, according to Google.
The question was:
"Is the number of reviews a ranking factor? Assuming all other aspect are the same, would a website with 100 reviews be considered of higher quality then one with only 10 for the same object? If so, how would one implement that value best ? Structured data?"
The answer from Google`s John Mueller:
"With regards to web search, as far as I know, no. Reviews is not a ranking factor.
"It might be different with local but with web search, that’s not a ranking factor.
"On the other hand, if these reviews are on your pages than that might be content that we can pick up, that we can show in search, and use as a ranking factor."?
