I tried running a mobile formatted quiz offer on AdMob -- 960 clicks later, no conversions.
CTR was 1.8% -- this seems ok, but I suspect click fraud from some of the sites I saw in the referrer logs.
At first I stupidly did not restrict geographically, but even after adjusting to English speaking countries (.20 min bid, then), I seemed to keep getting clicks from crap sites (looking at you, wap.in) and no conversions.
If anyone who finds this traffic source worthwhile (obviously they're out there) happens to see this, I'd love to hear a bit about what helped you get results. I don't expect specifics, but maybe things like: do you use an extensive filtering list, do you split test carriers, etc.
