Please do not post the same thing multiple times. The board software automatically flags certain posts as needing moderator attention. This happens the most often for new users. I'm pretty sure this is made clear at the time you attempt to post. Posting the same thing over and over again just makes that many more posts the moderators have to weed through later. This makes us sad. Don't make us sad. If your post/thread doesn't appear, just wait a while. Don't post it again. If it hasn't shown up by the next day, then you can try again. I normally go through posts in the mornings, and try to check a few times throughout the day, but I'm not here 24/7. There will typically be a significant delay before posts are approved. Just be patient.
@beginningiosdev (Shane, right?): I'm pretty convinced it's important, but it's more of a feeling and what people tell me. I recently interviewed Sam from cheddarapp.com and he was absolutely positive it is a must have. I've seen game devs too saying it's really important. I come more from a startup background and if you do want to control your message you need a press kit or else bloggers/journalists start writing wrong stuff (not saying it can't happen when having a press kit though). I'm under the impression that it applies to mobile apps too, and so we've been doing this. It doesn't take a lot of time and shows you're serious about your app. It can save you time down the road, too, for when you receive requests for visuals. All these reasons are why I put the press kit in the key elements to have on an app website, but I have no data to really back that up.
@AnthonyPham: The online presence does help sell more apps: it gives a place to redirect everyone (collect emails before launch, showcase your app) where they can find the links to download your app (especially if you have both Android/iOS apps, don't expect journalists/bloggers to put both in their post). It is also a matter of brand awareness, and visitors might not download your app straight away but they now know where to find you and who you are. You're not just a link amongst 700,000 others in the App Store and when they google your App Name they find you.
Which factor are you talking about? Like what element on the app website is the more important? I don't know how to measure it, but the way I see it you need to have them all. As for priority I'd say app name/icon (if they look for you in the App Store), then Call To Action (a big button to go download the app!) and something to REALLY show what your app is all about (I'm biased but I believe video is the best way - great screenshots and a good pitch/copywriting is a great start) and to convince users they have to download it. But then you also want them to find you if they need to (want to write about your app, send feedback instead of bitching in the App Store) so contact info is a must have. If I keep going I'm just going to say them all..
I actually plan to write a detailed post on how we do that for our apps, but it's not done yet so here's a short version:
We use bit.ly to create shortened URL for our Tradedoubler links (it could be linkshare links too, of course).
The idea is simply not missing out on these additional 4 or 5% that we could get, and using customized bit.ly links so that links we put on press releases and video descriptions (for example) are not too long.
Also, bit.ly lets you track where the click comes from (which website, obviously it won't work if it's direct - url address typed, or QR Code) so you can experiment. So we know what brings us clicks with bit.ly, and then with tradedoubler we know how many sales we got. Only thing missing there is knowing which bit.ly clicks bring sales, which we can't do at the moment.
That said, it doesn't amount to much money so far but I guess the larger the volumes the more it's worth it to implement that kind of things.
