Google Adwords? Facebook ads?

Anyone have any experience with either Google Adwords or Facebook ads? I'm trying both with a very small budget to see if I can drive more media folks here. Right now, my click-through rates are -low- — but I'm not even sure what qualifies as normal. Neither is coming anywhere near close to maxing out my allotted budget (I pay per click) per day, even as small as that budget is.

Anyone have any advice for making the most these? Or maybe alternatives like doubleclick?
