I ran a $50 Admob campaign over the weekend for a new FREE app we have on the Android Market. It did exactly what I needed it to, it got me about a hundred downloads. Today, that app has a little over 400 active users. The ball has started rolling, and it only took $50. THAT BEING SAID, the first time I ran an Admob campaign, I had just about the same experience as this writer. Admob works great for getting lite-version, free, download apps a little traction. I will never again run it for a paid app. IN-FACT, in the Android Dev Console, you'll notice that only your free apps have the "Advertise this App" link next to them. I assume that Google probably is very aware that Admob campaigns can work great for free apps, but it's a different ball game when it comes to paid apps. Lastly, I'd like to add that I took the time to create a graphical banner for my free app ad that made a BIG call to action - Download my new puzzle game for free.
