Here is a quick list of what you must think about when you want a good visibilty.
You must keep in mind that EVERY point is needed. If you focus on only one, it will probably useless.
- Your app icon must be attractive, and you screenshots as well. Most of the time, people will decide in a few second to download your app or not.
- Your app must of course be useful or follow a trend.
- A short description is appreciated, at least the first paragraph must make you understand what is your application purpose.
- Social links with your app will increase your popularity (facebook, twitter, …)
- You might consider going with a promotion booster which will make your app enter into the top rankings
- Think about optimizing your application keywords, a LOT of people use the AppStore search tool (around 65%). Use a iOS keyword tool to help you to build your keyword list (ex: http://www.apprankcorner.com)
- Track your user reviews. Top rated apps attract people, and most of the top ranked app are highly rated with 4 or 5 stars)
