I have created a small web app to easily transfer text across internet connected devices without relying on native clients. It basically works like pastebin with the addition of displaying a QR code of the link for easy scanning on a phone.
As I would like to monetize this to recoup my hosting costs (about 30 bucks a month since it's running it on Azure), the obvious solution would seem to put adsense banners and drive traffic to it.
How does one go about doing traffic generation for a web app where there's no content (text) to be written?
