Has anyone here used advertising to promote their app, specifically, on the iPad? We will be offering ads in our upcoming issue (we're an iPad travel magazine) and one of the markets we will probably be targeting will be other iOS developers. Right now we're just soliciting feedback (not looking to pitch you) on how well things might have gone, if any particular format worked well for you, and of course if it was worth it. If it wasn't worth it, what would make it worth it? Also, how much did it cost? (We're still deciding on rates). Can PM me if you don't like to share info publicly. Secondly, does anyone here offer ads in their apps independently (ie sells their own ads, doesn't use served up ads from iAds or other providers). We will be selling full page iPad ads and we're trying to get a feel for rates and success potential. Is it hard to find clients? How do you measure success for your clients and keep them coming back? Any feedback is appreciated.
