Hey there!
The Visibility Score is a score exclusive to Mobile Action. The main goal is to understand how visible an app is in the market.
The visibility score is scaled from 'F' to 'A+'. A high visibility score means that it's quite easy to discover your app while searching for a related app.
We calculate the Visibility Score by checking your overall app performance and especially your keyword performance. The main variables that affect your Visibility Score are as follows:
-Number of keywords ranked
-Search volume of those keywords
-Which position does the app rank on these keywords. I.e are they in the Top 10 or Top 5?
-Category ranking trends.
In short, if you app ranks in high spots for a lot of high-volume keywords, it will be much more visible. As a result your Visibility Score will go higher.
