Ad-Butterfly, an online ad services, allows more control over ad placement, providing marketers with the ability to choose which blogs to post there ads to, and allowing bloggers to choose which ads get posted to their site, according to a BusinessWeek article published Wednesday morning.

The world of online advertising continues to grow at phenomenal rates, but certainly, in the big scheme of things, it is still in its infant stages. The control given to AdWords advertisers and AdSense publishers has grown over the years, but Ad-Butterfly offers almost total control.

Ad-Butterfly works similar to the first tier PPC platforms of Google and Yahoo, using algorithms to automatically pair up ads and websites, but it offers a more advanced means of controlling which ads are displayed, for those who want total control.

Bloggers are given total control on which ads they will display on their site and also offers the ability for comments to be placed along side of the ads. Registered bloggers will also soon have the ability to request ads from other site.

The service is available in Japan and so far only 2,000 bloggers have signed up, but this form of paid ad placement is certain to grow over the very near future. Perhaps Google will even by them out it its quest for total control over online advertising. If you are fluent in Japanese feel free to visit the Ad-Butterfly website.
