The detector and instructions
Are your keyword rankings fluctuating a lot lately? Did your app suddenly unrank for certain keywords? Check out if you're the only one or if your app rankings are impacted by a major update to the Apple or Google Play algorithm.

How to use our Algorithm Change Detector?
Select the store (Apple App Store or Google Play Store), the country and date range you want to investigate. The peaks in the chart indicate we’ve detected unusual keyword ranking movements, suggesting an app store algorithm change on that specific date.
The two red lines represent the thresholds of unusual behaviour on the Apple or Google Play Store. If the anomaly score (blue line) is above the +3 threshold, the amount of keyword movements is unusually high. If the anomaly score for a specific date is lower than -3, that means that the keyword rankings are much more stable than usual (as if they were frozen). This can also be due to an algorithm change.
When you detect an algorithm change in a specific country, you can switch to the world map view to immediately see which other countries were affected by the update. Adjust the date and discover which countries were affected over a 3 day window.
