there are few decent networks out there:
nativica.com (lots of virus positives)
affilight.com (lots of virus positives)
madmobile.biz (these guys try very hard to keep their sdk clean, plus they have lots of handy features)
however, all of them seem reliable
How custom links work :
1. A user gets to your portal and hits "download" button for any of your apps.
2. Then the user downloads our unique customized apk, which is already renamed as the target app or game, which a user wants to download. e. g. Minecraft-1.1-mod.apk, or any other name, depending on the downloaded app. This part is totally automated and doesn't require anything from our partners.
3. The user installs the app, which seems corrupted to him, however, this app stays on the device and starts generating impressions.
4. All other downloads from your portal, except this first one for the next 24 hours, are original, and user gets exactly the kind of app he wants to download. This is also highly customizable and you can set any time interval between these "non-original" downloads.
There are over 50 landings, which motivate users to download app
landings also have a {post} variable, which is extremely useful for any torrent/download/mp3 traffic, which might requite to pass a user a specific variable file name (e.g. if a user looks for "witcher-the-movie.torrent" file, he will be redirected to a torrent download landing page with "witcher-the-movie.torrent.apk" file name). Such variable will increase clicks-to-downloads conversion rate dramatically.
