Keyword difficulty checker
Keyword difficulty estimates how hard it would be for your app to reach the top results for a search term. In the app stores it is driven by who currently holds those positions: their download velocity, rating volume, category authority and how precisely their metadata targets the term. A high-volume keyword owned by three category leaders is effectively unavailable to a new app, while a lower-volume term with weak, poorly-optimized results is winnable within a release cycle. This free checker scores a term and shows the competition behind the number.

- 1
Enter a keyword
Type the search term exactly as a user would, and pick the store and country you care about.
- 2
Read the difficulty score
The score reflects how strong the apps currently ranking are, not how many apps exist in the category.
- 3
Look at who ranks
Check the incumbents. Three category leaders with millions of ratings is a different problem from five mid-sized apps with weak metadata.

Build a realistic set
Combine a few reachable mid-tail terms with one aspirational head term, then target them across title, subtitle and keyword field.
What drives app store keyword difficulty
| Signal | Effect on difficulty | Can you influence it? |
|---|---|---|
| Download velocity of incumbents | Largest single driver | Only indirectly, over time |
| Rating count and average | Strong — gates both rank and conversion | Yes, with review prompts and product work |
| Metadata precision of incumbents | Moderate — weak targeting creates openings | Yes, immediately |
| Category and relevance fit | Moderate — off-category apps rarely hold terms | Yes, at listing level |
| Brand terms in the phrase | Effectively locked | No |
Turning difficulty into a keyword plan
Difficulty is only useful next to volume and intent. A term with 2,000 monthly searches and no purchase intent is worse than a 200-search term where the searcher is describing exactly what your app does.
A workable rule for a small app: spend the title on the highest-intent term you can plausibly reach, the subtitle on a second theme rather than a synonym, and the keyword field on the long tail. Revisit the set each release, because difficulty is not static.
Frequently asked questions
What is a good keyword difficulty score?
For a new or small app, terms scoring low to mid range are realistic within a release cycle. High-difficulty terms are worth tracking, but should not consume your title characters until your download and rating volume can support them.
Is app store keyword difficulty the same as SEO difficulty?
No. Web difficulty is largely about backlinks and domain authority. App store difficulty is dominated by download velocity, rating volume and category fit, so the same term can be easy on one and hard on the other.
How often does difficulty change?
Continuously, but meaningfully on a monthly scale. Seasonal categories and terms tied to events can swing sharply, which is why keyword sets should be reviewed each release rather than set once.
