I launched my app on the App Store and Google Play about two months ago and despite improving the icon and screenshots I have only reached around 40 downloads which makes me believe ASO is my main challenge. I started using ASO tools like TryAstro and AppTweak but the keyword metrics such as volume 39 and difficulty 0 are confusing so I would appreciate guidance on interpreting this data and on effective ASO strategies for a new app with minimal downloads or ratings.

I have been exploring App Store Optimization and noticed that Apple primarily uses the App Name, Subtitle, and Keyword field as the main text based ranking signals according to official and third party sources. Are these the only factors that truly impact iOS ASO, or do elements like the app description and promotional text indirectly influence visibility, conversion, or ranking updates over time, and how frequently should subtitles and keywords be revised after launch.
