Facebook will unveil its plans for a mobile ad network at its F8 conference on April 30, according to a Re/code report. This comes after Facebook started testing ads in third-party mobile apps earlier this year, signalling a move towards working directly with its partners rather than outsourcing the work to an outside ad-serving platform.

Re/code reports that Facebook will appeal to publishers and developers by leveraging the social network’s database to create more precise ad targeting.

UPDATE: A Facebook spokesperson tells TNW the company has nothing to say regarding this, but notes that there are “rumors and speculation leading up to F8, as can be expected.”

Twitter recently also started to step up its focus on mobile ads via a new tweet format and integration with MoPub, the world’s largest mobile advertising exchange, which it bought last year.
