Method
How AppStoreStatistics uses it
AppStoreStatistics models difficulty from public search-result signals such as the strength of ranked apps, rating pressure, rank density, brand presence, and result composition for the selected country.
Example
Plain example
A generic keyword such as "fitness tracker" can be more difficult than a niche keyword because many high-rating, high-recognition apps compete for the same search result.
Avoid these mistakes
Common mistakes
- Treating difficulty as official Apple search volume.
- Ignoring relevance and choosing only the lowest-difficulty keyword.
- Comparing scores from different countries as if the search results were identical.
- Assuming a low score guarantees a high rank.
