Qu'est-ce que ASO Keyword Research ?

Keyword research is the foundation of every ASO strategy. Without understanding what your target users are searching for, you are optimizing blind. The process starts with brainstorming seed keywords based on your app's core functionality, then expanding that list using ASO tools, competitor analysis, and autocomplete suggestions from the app stores themselves.

The key metrics for evaluating keywords are search volume (how many users search for the term), difficulty or competition (how many strong apps already rank for it), and relevance (how closely the term matches what your app actually does). The ideal keyword has high volume, low competition, and strong relevance. In practice, you will rarely find keywords that score perfectly on all three, so keyword research involves strategic trade-offs.

Tools like AppTweak, Sensor Tower, Mobile Action, and data.ai provide keyword suggestions along with estimated search volume scores and difficulty ratings. However, these scores are relative estimates, not absolute numbers. Cross-referencing multiple tools gives a more accurate picture. Beyond tools, mining your competitors' metadata is one of the most effective research techniques. Analyze the titles, subtitles, and descriptions of the top 10 apps in your category to identify terms you may have missed. Apple Search Ads also provides a "Search Popularity" score that reflects real search volume on the App Store, making it a valuable data source for iOS keyword research.
