The basics

What is App Store Optimization (ASO)?

App Store Optimization (ASO) is the practice of improving a mobile app's store listing so it ranks higher in App Store and Google Play search and converts more of the people who see it into installs. It's often called "app store SEO", the same idea as ranking a web page on Google, applied to the two app stores.

Strong ASO comes down to two things: metadata (your title, subtitle or short description, keywords and description, which determine the searches you rank for) and conversion (your icon, screenshots, ratings and copy, which turn searchers into installs). The tools above score and improve both, separately for the Apple App Store and Google Play, because each store ranks listings differently.

App Store Optimization (ASO) is the practice of improving a mobile app's store listing so it ranks higher in App Store and Google Play search and converts more visitors into installs. It covers your title, subtitle or short description, keywords, screenshots, ratings and description, the elements each store uses to rank and sell your app.
The score checkers are. You can check your App Store or Google Play ASO score with no sign-up, and your 0 to 100 score and grade appear instantly. The full per-check report with AI-written fixes and the listing generators are part of Max, which starts with a 7-day free trial. Your card is taken up front, and you pay nothing if you cancel before day 8.
Apple indexes the title, subtitle and a hidden 100-character keyword field for search, but not the description. Google Play indexes the title, the 80-character short description and the full 4,000-character long description. So the same app needs a different metadata strategy on each store, which is why we offer separate tools for each.
No. The ASO score checkers show your score, grade and category breakdown for free with no sign-up. The full per-check fix list and the listing generators are part of Max, which starts with a 7-day free trial.
The best free ASO tool is one that scores your listing against the factors each store actually ranks and shows specific fixes. ReachFront's ASO checkers do that for free, with no account, for both the App Store and Google Play, and the Play rating checker and app rank checker are free too. The listing generators, which write optimized metadata within each store's character limits, are part of Max.
