I'm using Bing PPC to get opt-ins. I have a good campaign going on with a CTR of around 5%, with low CPC. I've gotten 10 email submits out of 35 clicks. But the problem is only 38.5% opened the lead magnet I was using (as shown in aweber statistics). And none of them clicked the affiliate links contained inside the leadmagnet (I know because I'm tracking them). What may be the problem?
