So I've been playing around with PW a little bit over the last couple of days. I've been placing a bunch of small bids on low-to-medium traffic websites, and that's been doing OK so far.
Last night, following some advice I got on webcomics.com, I pulled all the ads that had been running for more than a week (figuring they'd probably reached as many eyeballs as they were likely to), and placed a couple of big bids to run for a couple of hours on Dr McNinja and Questionable Content (targeting People Who Like Really Weird Comics, and Female Readers respectively).
I'm now down ten bucks, but up somewhere between 500 and 6,000 uniques (depending on which set of traffic stats you trust) in a single day. Now to see how many of them stick around...
So, opening the floor for discussion: in people's experience, is it better to cast a wide net or to go after the big fish? Do you put your ad on a lot of small sites for a couple of cents a day, or spend the same amount of money for four hours on one of the really popular sites? (translated for those who don't understand fishing metaphors)
