How does decimal rounding of reviews to stars work in ios appstore?
Starting from which average review score to get full 5 star rating?Duolingo has a 5 star rating, but I doubt that they really have an all time review average larger than 4,75. In the google playstore their average of the android version is 4,6. Does anybody know how apple calculates the star ratings or has an URL reference where this is explained?

Get iOS or Google Play link of app and paste it on SDTT (Structured Data Testing Tool).
That's all. In SDTT they're even deep than 3 points...

Peter, thanks a lot.
How did you get the 3 decimal ratings of the apps in itunes?
-
Mobile dev here!
So for all stores (AppStore + GooglePlay + Microsoft Marketplace + Amazon App Store + etc) algorithm is simple - they calculate ALL ratings on all versions. Some of them only for local store, other for global.
Example Duolungo:
https://itunes.apple.com/bg/app/duolingo-learn-spanish-french/id570060128?mt=8 <- this is in local Bulgarian Market. 4.928 in 9 ratings.
https://itunes.apple.com/us/app/duolingo-learn-spanish-french/id570060128?mt=8 <- in US market. 4.791 in 4068 ratings.
https://play.google.com/store/apps/details?id=com.duolingo&hl=en <- Worldwide. 4.648 in 2343538 ratings.As you can see sites provide correct review rating to Google but they rounding it. Probably your guess for over 4.75 is correct. There isn't official explanation from Google about this. Some sites showing 5 star rating system. Other 10 star - 0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5. For other it's complicated because i have seen even results as 4.2 and this is 100 star rating system.

Any Success Getting Fake 5 Star Google My Business Reviews Removed From Competitors?
Hi, I am working on a competitor who is obviously building up fake reviews using a 3rd party service. I need to build more evidence. A majority of his reviews on Google My Business, they are done by reviewers with very few reviews (no profile pic), and that seem to review 3-4 companies in the Chicagoland area the exact same day. This happens again and again. It started about 1.5 years ago. Before that everything looks normal. Any idea how much proof I need to actually get those reviews and/or his company removed? I am working on getting access to a private group on Facebook where he talks about it. Thanks in advance!

Google Reviews & Third Party Reviews
Hi We have a third party review provider, but were also looking at increasing our Google reviews. However after more research, should Google reviews only be used on local listings? For organisations which don't have a physical location to buy from - is the solution to use organisation schema, which incorporates 'reviews on other sites' with the hope Google may show your Feefo review count? When checking similar companies - all seem to have the organisation knowledge card and not the local Google My Business listing. Is it worth pursuing extra reviews on Google My Business or not? Thanks!

Why does this business have an average of 4.8 and not 5?
I was doing some research today and came across a business that has 5 reviews, all 5 stars. For some reason, their average is showing as 4.8, instead of a perfect 5. Looking at some other businesses, I see one with 4 5-stars, 1 4-star, and 1 1-star. 25/6 = 4.1666666. That would round to 4.2, but Google lists them as 4.3. Is Google just bad at math, or are they using some other factor in calculating these averages?

Moving my photography business to another state. Is it possible to transfer Google My Business listing WITHOUT losing my Google Reviews?
A friend of mine is transitioning her photography business to another state. She moved about 5 years ago and consequently lost all of her Google+/Yelp reviews. Having reviews as a photographer is EXTREMELY important for her business reputation. She doesn't want this to happen again. Is it possible to change the location of a Google my Business page and keep the existing reviews? Thanks

Publishing testimonials on your site that are from your Google + (or other review sites page)
Ive got a site with some good Google + Reviews and some other good reviews on other sites that id like to be able to publish on a testimonials page on our website, but im worried about being penalised for duplicate content. Any idea of the best way to get these reviews on to our website, i was thinking about placing the text in as an image, but id prefer to do something semantic if at all possible. (I know that some review sites have javascript widgets you can use to pull in your reviews but for most of the sites we are reviewed on they dont)

Migrating Reviews from Old SIte
We recently changed our Website to Word Press and I would like to move the old reviews to the new site. I am concerned Google might not understand the reviews showing up all of a sudden. The old reviews were on a sub-domain (store.domain.com). I will be able to match the dates and text as well as names. Any advice or Best Practice on this? Thanks!
