ASO (App Store Optimization) keyword research is the process of identifying the keywords and phrases that potential users are searching for in relation to your app. By understanding what people are searching for, you can optimize your app’s metadata (title, description, keywords) to appear higher in search results and increase visibility and downloads.

Identify your target audience and their interests.
Use keyword research tools to find relevant keywords and phrases.
Analyze your competitors and see what keywords they are using.
Optimize your app’s metadata with the keywords you’ve identified.
Track your rankings for the keywords and make adjustments as needed.

It is important to note that ASO is an ongoing process and requires regular monitoring and updates to stay effective. Additionally, following the guidelines and rules provided by the app stores is important to avoid any penalty or rejection of the app.
