Could you perhaps point us all in the direction of an article that gives some useful solid advice?
What if there isn't any?
A generic, bland article that tells you nothing besides "Enter good meta data". There are already hundreds of blog posts out there with such a cheap "advice", mostly from small companies that want to sell ASO. Where are the new insights? Anything measurable?
I work at AppTweak. we offer both a tool that allows our customers to perform their own ASO campaigns and a consulting service where we do the job for them.
On the consulting service, we usually see a download increase that ranges from 5% to 30%, depending on how much time/talent the client had put in ASO before calling us.
Anyone have a ballpark estimate for the % change in downloads some of these SEO tips might get you?
