Writing the App Store Description

The description of your game in the App Store needs to follow some golden
rules. Let's face it: most potential buyers will only read the first lines and then
jump to the screen captures. At this point, there are three possibilities: they buy
it, they go away, or they read further to make up their mind. I am not sure that
the third option will be the most common. What does this mean? It means that
you need to focus your key messages in the top of your description.

In addition, your content should not be static over the time. For example, if you
decide to have a new-school-year sale, then advertise it on the top for the
limited period of the sale.

Here are my golden rules for game description:
 State positive feedback from customers or recognized
reviewers.

 Be direct and short in your game description.
