You’d be surprised to find out how many things you can do on your own to help your app’s ranking.

The “Learn how to promote your WP7 app” paper offers practical tips and tricks from both the
developer and marketing perspective for which you don’t need any marketing background and hopefully
should not take too much of your time. The topics discussed are: presentation of your app and tracking
your statistics, ideas about how to build your most loyal users’ core, how to increase downloads through
in-app tricks, in-apps ads, external promotion and links to currently running Windows Phone competitions.
