Why ASO? …
"App store optimization (ASO) is the process of improving the visibility of a mobile app (such as an iPhone, iPad, Android, or Windows Phone app) in an app store (such as iTunes or Google Play for Android). App store optimization is closely related to search engine optimization. Specifically, app store optimization includes the process of ranking highly in an app store's search results and top charts rankings. ASO marketers agree that ranking higher in search results and top charts rankings will drive more downloads for an app.” - Wikipedia
It is generally much easier to do than SEO as the app store is less mature so it doesn’t take much effort. Plus its free and the effects are long lasting. Everyone should do this because of the huge ROI (Might have considerable effect, doesnt take much time once you understand it).
