Facebook may change the face of mobile marketing as we know it in response to the social network’s rumored plan to launch “featured stories” within weeks.

Analogous – at least in theory – to Twitter’s Promoted Tweets, Facebook may begin adding “featured stories” into people’s mobile feeds. What does this amount to? Marketing-led posts that could deliver invaluable opportunities to advertisers of every variety.

But Facebook has already denied the welcoming of any “rich media featured stories.”

“We want to clarify that we are not working with any agency to create paid ads on our mobile platform,” a spokesperson for Facebook said Monday.

Still, with its IPO on the horizon, Facebook clearly has a strategy to begin generating marketing dollars out of its 425-million active mobile user base.

What will the rumored mobile ad platform look like? For now, only hazzy comparrisons can be made. But by early March, Facebook’s “featured stories” may go live. And in the process, they may change the landscape of mobile marketing dramatically.
