There are numerous ways to get your app to show on the search results, but mainly what you want to do is optimize your app. What does this actually mean? Well firstly put yourself in a position of a person looking for an app like yours and see what would you type in the search bar to find your app. Be creative, find similar words, search for synonyms of the most frequent words etc. Once you got yourself a few words from there, go to your best competitors and see what they are using in their descriptions and titles.
Those are some basic ways how to get yourself so called keywords and try to mention them in your description etc. But remember, having only this does not always equal to lots of downloads, a quality landing page is a must. By that I mean your screenshots video etc. need to be of high quality.
Just remember that if your are on iOS app store, description words do not play a role but for android app store they do. And also, your title has the strongest SEO effect on your app's visibility.
