Hey STM - Thought I would share the results of a quick test campaign I ran for a free flashlight app in Chile. On my first round of tests, i had a feeling that a certain percentage of the traffic was botridden and was trying to figure out how much traffic i was loosing. The screenshot speaks for itself. Now the real questions are:
- Do people click on random things to see what its about?
- Are people somewhat guided to click?
- Do most traffic sources have bots?
I'm thinking yes to all but let me know what you think.

Mostly accidental clicks.
Bots, yes for sure - especially on CPC networks like Airpush
When its not clear how to close the alert people often just click on it
Even in a small country like Chile you'll have at least a thousand app id's (more likely a few thousand) coming in at the beginning of a campaign. You probably only have a few clicks per app id so I'd say that your conclusions about bot traffic are a bit premature.
With that being said, Airpush does have a lot of bot traffic but you need to be looking at individual app id performance to determine where your bot traffic is coming from.
The best way to weed out bot traffic is to run an entry pop landing page, or a landing page with an entry pop, and let each app id accumulate around 50 - 100 clicks. By using an entry pop the user MUST to click "okay" on the javascript alert. When you have an app that is sending bot traffic there will be no click through (0% ctr) and it will be very obvious which app id's you need to cut.
@zeroonedigital - Yep I run bot tests most of the time but it was still quite surprising that the CTR was at the top.
