Review rating score calculation
I am wondering what is Googls's calculation method of review rating score, I guess is: (1star*QTY+2star*QTY+3star*QTY+4star*QTY+5star*QTY)/QTY in total
But actually, example: lightinthebox.com
Result is not as I guess
So I am wondering, what calculation method is actually?
Re: Review rating score calculation
This is what Google says
"We calculate Seller Ratings using a variety of signals beyond just the arithmetic mean in order to make sure Seller Ratings reflect not only the raw quantity of review scores, but also how representative and high-quality the reviews are. We're constantly refining how we use those signals to give our users as helpful an overview as possible."
