Excuse the sheer newbie-ness of this but... My entertainment content site (no product for sale...) does well for Yahoo search traffic. Yahoo over-all may be a better fit than Google, but I'm struggling understanding the set-up for 'site targeting'. Ad Words tells me search.yahoo.com is "unavailable" for targeting, and I'm not really understanding how high the bids have to be for other targeted sites. Explanation, anyone?
Um, pretend I didn't ask.... Doh. Although I suppose it raises the subject, if you're getting a lot of natural search via Yahoo, would you double-up with Yahoo Search ads, Vs. sticking with Ad Words for all your budget?
