Hmm. My premier ad has a prime position at the top of the page. My standard ad is buried waaaaaay down underneath Da Blog Poll on the sidebar.
Yet, last I checked, the premier ad is showing the “your ad here” default image, and hasn’t yet even made me a cent, while the standard ad is going for three cents and has made me a nifty two cents so far. Admittedly, the premier ad isn’t showing up on the feed like I intended for some reason, but for future reference, chicks dig the tall ad.
Perhaps I shouldn’t be surprised; I’m getting a lot of comics- and webcomics-related bidders, and it’s rare that I’ll see a webcomics site put up a banner ad.
