      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...

              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.

                Is It Beneficial to 'Like' My Clients Google Reviews?

                I have a client who is insisting that all of us in the office 'like' his positive reviews on Google. My boss & I are fine with doing this, but due to the industry the client works in, my staff is questioning doing this or not because they do not want to be associated with his company outside of work. Is there any SEO benefit to us liking his reviews or is this more for him to feel better that people are reading them? Does my staff have anything to worry about if they do 'like' his reviews?

                Review Schema Dropped Off A Cliff!?

                Hello everyone, I recently implemented some review schema for my website which looked to be successful as my review stars were appearing in organic rankings with no problem! Yay! However... I've just checked in on where we are with these and they have literally dropped off a cliff and I have no idea why. See image attached with the graph that shows our reviews looking great in July/August then dropping off w/c 26th August. I literally have no idea why this has happened. The Schema Markup Tool shows no errors or issues with the markup either. Can anyone advise? 81Rv88Y

                Any experiences with Reviews.io?

                Hello, We have used Trustpilot.com for a few years in the past. Service was reasonable and they did what they were supposed to do. However, due to their price and requirement for a full-year payment upfront we stopped using their review collection service. Is someone using Reviews.io? They are included in Google Review Partners, which seems to be very encouraging:
                https://support.google.com/adwords/answer/2375474?hl=en Also, they have a decent price for their intermediary package (about $ 89/month) and don't require a yearly contract like Trustpilot and some others. Any experiences you could share about Reviews.io will be appreciated. Luciano, The Translation Company Group

                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?

                What's the best way to keep Google My Business reviews when the business changes names?

                I work with an interior designer who is re-branding and changing her business name to focus specifically on windows. Can she keep her GMB reviews and just change the name of her business, then reverify with Google? She doesn't want to lose her current local pack ranking.

                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

                Do schema review numbers have to be manually updated?

                Hi! I've had success with review schema rendering in SERPs but have had to manually code the numbers and update those numbers as more reviews come in (which is a bit time-consuming). Is there a way to use auto-generated numbers that will still render schema or do those numbers have to be manually added? I've looked at the schema for sites like IMDB, and their schema numbers seem to be manually added, which seems like a huge lift. Advice/input is appreciated!
