BuySellAds has just released a new extension for Google Chrome (with a Firefox version on the way) that is aimed at advertisers. It displays a BuySellAds icon in your toolbar, which lights up red when a website you visit has BuySellAds zones available. Clicking it displays a popover dialog that shows the publisher’s zones and lets you buy them out.
I think it’s a neat idea. It makes it easier for advertisers to find and buy ad space, which could potentially result in smaller publishers having their ad space filled.
If you do any advertising, or just like seeing how much publishers charge for their ad space, you can download the Chrome extension here. (And don’t forget, Webmaster-Source has BuySellAds banners…)
