After a few days running the $0.02 AdMob campaign for GPS, find me! I terminate my budget.
My first impression is good and I am very satisfied because for only $45.06 I got 259,194 impressions and 4,172 clicks, which is much more than what I could get by sending messages to forums or paying for a review.
I am not so naive as to think that all clicks were done on purpose as there is certainly a large percentage of unwanted clicks and clicks made for the sole purpose of supporting the application that shows the add.
But the effect on the download is visible as you can see from the graph below:
A marks the day when I begun the $0.01 campaign and B the day when I started the $0.02 campaign. The little increase of downloads in the period AB could be a simply statistic fluctuation, but after B there is a real increment. In just five days I got 68 installs!
Now that the campaign is over I want to see if these 68 new installs would generate more downloads via the mechanism of the "tell to a friend".
Next week an update.
