Very shallow guide, IMO.<p>There is much more to do in order to do a successful launch, such as:<p><pre><code> - Pick a good name
- Choose the right keywords and structure for the description
- Analyze your competitors and pick your keywords accordingly (head-to-head confrontation? Or better target your own subniche?)
- Prepare appealing screenshots
- Make sure the logos and other promotional images look professional (a hundred bucks from a good designer can go a long way)
- Set up a coming soon page and try to grab e-mail addresses (way before launch, of course)
- Prepare the docs and templates to eventually outsource the customer support (and even the development)
- Maybe buy some ads
- Do cross-promotion from your other apps
- Maybe set up some partnership for cross-promotion (if it's your first app)
