Since the Apple TV got released I have been running Apple TV Apps, a blog and Twitter account showcasing the best Apple TV apps available. With discoverability being sub-par compared to the iOS app store, the site has been moderately successful and I've been contacted by a number of developers with iTunes links to their apps asking me to feature them, but there's a problem. Those links don't go anywhere; no web previews, no way to view these apps in iTunes.
Graham Spencer summed up what is needed from developers really well:
Apple TV developers, *please* make sure you have a landing page with screenshots, info, price and press kit!— Graham (@greyham) November 9, 2015
The page doesn't have to be the most beautiful website in the world but the information needs to be available if you expect your app to be featured anywhere. There are a number of options to get a simple website up and running with very little effort.
Although Wordpress and Tumblr are both blogging platforms, they can be used as landing pages with a little bit of tweaking in the settings.
At a minimum, you should have:
Some other things that will help market your app:
For an example that fits all of these criteria, check out the landing page for Almost Impossible!.
Until Apple allows web previews for Apple TV apps, your goal should be to replicate all of the information you have in the app store. If you at least some of the above, your app is much more likely to be featured and also it will help customers decide if they want to buy your app.
