Yahoo! has signed a deal with social networking site Bebo to become the sole supplier of adverts to the group.
As the popularity of social networking sites continues to grow, a number of major search engine providers, namely Google and Microsoft, have signed deals with other network providers to provide advertising.
Dow Jones Newswires reports that Yahoo! believes the deal will "substantially increase" advertising the company deals with, citing a statement issued by the firm.
The move, which will allow web marketing towards users of Bebo to increase, follows similar agreements with other sites such as Facebook and MySpace.
Bebo has more than 10.5 million users in the UK and Ireland, who predominantly fall into the 13 to 24-year-old age range, the Times reports.
The deal is apparently set to run for a number of years and will see Yahoo! sell both standard and video advertising, Dow Jones reports.
