Keywords are an important part of app store optimization (ASO) on the Google Play Store. When users search for apps on the Google Play Store, they typically use keywords to find apps that are relevant to their interests. By using relevant keywords in your app listing, you can increase the chances that your app will be discoverable by potential users.

There are several ways to research and select keywords for your app listing on the Google Play Store:

1. Use Google’s Keyword Planner: This tool allows you to see how often specific keywords are searched for on Google and can help you identify relevant keywords for your app.
2. Look at your competitors: Check out the keywords that your competitors are using in their app listings and consider using similar keywords in your own listing.
3. Use Google’s autocomplete feature: Start typing a keyword into the Google Play Store search bar and see what suggestions appear. These suggestions can give you an idea of the types of keywords users are searching for.
4. Use keyword research tools: There are a number of keyword research tools available that can help you identify relevant keywords for your app.

Once you have identified a list of relevant keywords, be sure to include them in your app title, app description, and app metadata to increase the chances that your app will be discoverable on the Google Play Store. It’s important to remember to use keywords sparingly and avoid keyword stuffing, as this can negatively impact the visibility of your app.
