Having some trouble with this method... I have an ad up right now (actually four split-tested ones) that is well-targeted IMO with a poll and related offer after the vote. I started it out right away at $.10 CPC and got about 1,000 views and 2 clicks (good CTR, right?) before it suddenly stopped showing to any users. The target group is about 6.5 million large. I upped the CPC and got about the same results, but around 9,000 impressions and 9 clicks it stopped showing to anyone again. Now I've upped it to .30 bid (which is barely, if at all profitable) and have received basically no more impressions, AGAIN. What am I doing wrong? CTR is healthy, daily budget is at $100 (most I can afford on testing this right now)...
Also, conversions. I've had 15 clicks so far and just one conversion (spending more money than I'm making by far). Is this a case of small sample size, or should I be legitimately worried about my offer and poll at this time? Offer is a simple e-mail submit that's very highly correlated with my poll's question.
