Improved Keyword Installs starting July 17, 2025
Starting July 17, 2025, we're updating our keyword installs estimates. This change will make keyword performance trends even more precise, especially when looking at historical data.

Keyword Metrics by App are KPIs that AppTweak has been able to gather or estimate about keywords. See below for a list of available metrics.

Metric name	Description	Origin	Historical Data Available?
rank	The position of the queried app in the search result list when a specific keyword is searched for.	Gathered directly from the stores	✅
installs	Number of users that search for this keyword and then install the queried app	AppTweak estimates	✅
chance	A score between 1 and 100 that indicates how likely your app is to rank in the top 10 search results for the selected keyword.	AppTweak-defined KPI	➖
kei	KEI (Keyword Efficiency Index): A score that indicates the visibility potential of a keyword, taking into account keyword volume and chance score.	AppTweak-defined KPI	➖
relevancy	The relevancy score is an indicator between 0 and 100, indicating how relevant a keyword is for your app. A higher score indicates higher relevancy. The relevancy score is based on the app store ranking algorithm, hence targeting highly relevant keywords ensures that your app shows up when users search for the solution you offer.	AppTweak-defined KPI	➖

How are Keyword Installs computed?
Keyword Installs are an estimated number of organic installed received by an app from a keyword. They are based on:

current or historical app ranking on a keyword

current keyword volume

App Keyword Ranking Current takes into account the today's app ranking and today's keyword volume to provide a keyword install estimation.
App Keyword Ranking Historical takes into account the historical app ranking and today's keyword volume to provide a keyword install estimation. This means that the historical keyword installs may vary if your keyword volume evolve through time. Therefore we recommend fetching data regularly and save it to have a more accurate picture.

This information is exposed through two endpoints:

The Current endpoint which returns the latest - most recent - data available
The History endpoint which returns the historical daily values over a given period of time
