Hi,
I've been looking for android-market SEO information for a long time but I couldn't find out anything

- Do you happen to know how to promote, improve, etc. an application in the android market?
- Do you know why the market seems to give preferential treatment to some applications?
- Factors such as total downloads, active installs, ratings, etc.: do they improve the visibility of an application?
- Can you improve the visibility of your application in the market with mechanisms out of the market? -> web promotion of your app, SEO techniques for the "official website" of your app, viral videos, etc.

I hope you can help me with this questions. I think they are really interesting for all the developers comunity!
Thanks in advance!
