The Update Frequency of App Store List and The Clearance Algorithm, What You Should Do on The Best for Your App?

Jun 25 2021




App Store 2021 the first four months of the number of list clearance increased significantly compared to last year, 2020 daily list clearance number basically remained below 20, while this year the number of daily list clearance is basically above 20. So it seems that Apple has increased its strength in the list clearance.

List clearance refers to the removal of an app's ranking in each chart. Usually, after an app got cleared, you can still find the app through "Search", and normal download and update operations will not be affected.

However, for apps with front ranking, the traffic loss is huge once they got cleared.

Reviews are an important factor that affects the conversion rate of App Store traffic, and the details of reviews are likely to directly affect users' downloading decisions, so many products have review anomalies, which are manifested as too many positive reviews and abnormal review content.

App has not been updated for a long time

When an app has not been updated for a long time, apple will consider it "abandoned" by default, so it will be cleaned up.

Developers should optimize and iterate their products from time to time to keep them running properly and provide users with a better experience while avoiding being taken down by Apple as "abandoned apps".

Accidentally attacked by Apple

If there is suddenly a large number of downloads over a period of time, resulting in a surge in the ranking of the list, even if it is a real user brought in through massive advertising, it may cause Apple to suspect and lead to being cleared from the list.

What should developers do in this situation?

If such situation happened to your app, developers are advised to report to Apple in advance when the product will be promoted through channels, activities and other means, and the download level will rise massively, in order to avoid being misunderstood by Apple.

The notification email should reflect the reasons for the increase in the download level and the importance of Apple's regulations.

If you have already been wronged, you can contact Apple to file a complaint. When filing a complaint, you should explain to Apple that the recent additions to your product are all regular customer acquisition, and you can provide screenshots of the promotion channels, screenshots of the effect settlement, and the active, retention and other behavioral data of the recently added users.

According to the data in the past month, the list can be restored to normal after 2-3 hours, so developers just need to wait patiently and don't worry too much.
