Site Targeting Day 1

This isn't going to be fair, but I'm going to shoot from the hip. Day one (or should I say morning one) of site targeting was a disaster for me. I started with a low budget (which this probably isn't for) because I've had strong success playing low budgets on AdWords before; low budgets are a big part of its appeal. But that was CPC and this is CPM. I one glaring mistake: I was not selective in the sites I chose to have carry my ads. I simply chose a few keywords and selected nearly all of the sites tied to those keywords. The result my budget (A whopping $4 for the day) was spent before I left for work at 7:45am. So this was partially (okay mostly) my fault but at such a low budget I'm surprised I received the number of ad impressions that I did, and so quickly. $4 will get you 2,000 page impressions in a matter of hours with no guarantee of clicks. Compare this to one of my CPC campaigns which so far today has received 1,872 page impressions with 2 clicks at a total cost of 10 cents. So I paid $4 for Zero clicks and 2,000 impressions in a CPM campaign, that was all spent before my audience is awake. In order for this to work I need to be more selective and actively decide when my ads are viewed (since my ads do their best work for me at lunch and dinner time). But it was a nice little experiment and one that I'm happy I took part in, and will reevaluate and perhaps try again.
