Apple Search Popularity Score

iOS only


A score between 1 and 100 that shows the level of competition of a keyword. The higher the number, the higher the competition. A high Difficulty score indicates that powerful apps rank in the top 10 search results, making it more difficult to rank high for the keyword.

AppTweak-defined KPI
