Social networking website, Bebo, is set to launch its first advertiser widgets which are small web based applications that social site users can embed in their personal profiles.

One of the widgets is an advertiser supported photo-sharing widget from Slide, Photobucket, and Rockyou. The company plans on adding a variety of other widgets users can add to their profile such as video and music players. The ad widgets are part of what Bebo vp of sales and business development Jim Scheinman calls “engagement marketing,” designed to combine Web ads with user-directed viral marketing. Visitors to a profile with a widget for their own page can add it with a couple clicks.

“If it’s great content, it’s going to engage the user so much more,” he said. “To the Beboer, they don’t look at it like advertising but great content.”
