Keyword metrics are numerical properties that AppTweak has been able to gather or estimate about keywords. Metrics are exposed through two endpoints:

Keyword Metrics - Current returns the latest - most recent - data available

This endpoint returns the data for today. If AppTweak hasn't stored the data, the data will be fetched live on the store.

Keyword Metrics - History returns the historical daily values over a given period of time.

This endpoint returns the data from AppTweak's databases. If the data is not available, you'll get a "null" response and you won't get charged credits for the datapoints.

See below for a list of available metrics.

volume	A score between 5 and 100 that shows how popular a keyword is in terms of searches. The higher the number, the more popular the keyword is. Only available in countries where Apple Ads is available.	Apple Search Popularity Score	✅
difficulty	A score between 1 and 100 that shows the level of competition of a keyword. The higher the number, the higher the competition.
