So you’re ready to launch a mobile app? Are there things you can do as you launch to make it a top-ranked moment? Mashable has eight best practices and here are few to share:

• The first two weeks of your app’s life are the most critical, according to Mashable’s analysis. Get your marketing and cross-promotion plan in place well before the launch of the app. We’ve seen a number of paid apps, particularly in the travel space, actually launch with a widely publicized “free day” to spark as many downloads as possible and get to the top of the app charts.
• Cutting your app price can help you move up. Mashable says “10 percent of top apps that have had the most dramatic chart position change have cut prices.”
• Size matters. If your app is over 20MB, it will require a wireless connection for download. That will affect your sales if users aren’t on wifi and can’t make an immediate purchase.
