As of today, we've changed how we calculate and display an app’s overall star rating, from a historical average to a weighted average that favours recent reviews. As apps change over time, we want to ensure that merchants see a rating that’s more reflective of the current capabilities of your app.
Please note that there shouldn't be a noticeable impact on your search and category ranking.
If you’re concerned that the volume of reviews you’ve received hasn’t grown inline with your app improvements, take note around best practices for asking for reviews. We also recommend replying to reviews as we’ve seen a positive correlation in review replies and updated star ratings.
