1. Download Rates:A high download rate is a strong signal of an app's popularity and relevance. When an app is downloaded frequently, it suggests to the algorithm that users find the app valuable or interesting. This can lead to higher rankings, as the store aims to promote apps that are in demand.
2. Uninstall Rates:A high uninstall rate can be a negative signal to the algorithm. If an app is downloaded but then quickly uninstalled by a large number of users, this may indicate issues with the app's quality, performance, or relevance to the users' needs. Consequently, the algorithm may lower the app’s ranking to ensure that users are more likely to find high-quality apps that they will retain.
3. Retention Rates:The flip side of uninstall rates is retention. Apps that not only get downloaded but also are retained by users over time signal to the algorithm that the app has lasting value. High user retention can positively affect an app's ranking.
4. Engagement Metrics:Beyond just downloads and uninstalls, the algorithm may also consider user engagement metrics such as daily active users (DAU), session length, and frequency of use. These metrics can provide a more nuanced view of an app's value to users.
5. Velocity:The speed at which an app accumulates downloads, especially after a new release or update, can also influence rankings. A sudden spike in downloads can indicate trending interest, which may temporarily boost the app's visibility in the store.
It's important to note that these metrics are not considered in isolation. The algorithm likely weighs them against a wide range of other factors, including user ratings and reviews, app quality signals (like crash rates), and the relevance of keywords in the app's metadata.
Developers aiming to improve their app's ranking should focus on creating a high-quality app that meets user needs and encourages long-term engagement. Marketing efforts to boost downloads should be paired with strategies to keep users engaged and minimize uninstalls, such as through regular updates, bug fixes, and new content or features.
