I noticed that when I push a new update for one of my apps, it bumps it to the top of the “Just in” list for my category. When I tried the same for my newer app it didn’t promote it the same way. I decided to do some research and found that if you wait about a week between your updates, the Android Market will bump you to the top. That’s actually pretty convenient for a smaller app since a good dev cycle including plenty of testing is about a week (at least for me), and discourages posting constant trivial updates just to continue to stay at the top of the list.
Why is this feature in the Android Market a good thing? People are constantly looking for new content, new games, and updates. You would think it’s kind of cheating to bump yourself to the top of the “Just in” list every week, but it’s really a good thing for developers as well as end users. It ensures that applications that are under active development get exposure while stale ones bubble down to oblivion and also promoting bug fixes and feature additions for anyone wanting the attention. It is a necessity especially in the Android Market with the store becoming flooded with duplicate and garbage applications.
