It's A New Idea: Twitter Finally Reveals Its Plan to Make Money From All Those Free Tweets Posted Everywhere

Promoted tweets will now appear in third-party apps like Flipboard.

Promoted tweets are going to show up outside of Twitter for the first time, the company announced today, revealing part of its strategy for increasing ad exposure that had been been limited to its own site and apps.

Now, it will serve paid Twitter messages to partner sites and apps, including Flipboard and Yahoo Japan, partly owned by Yahoo. Both Web properties already have strong Twitter integrations with sections devoted to streams of activity powered by the social messaging site.

Twitter said its Promoted Tweets would show up in those Twitter content areas on the third-party sites, as well as in other sections of the sites, and the ads would have the "same look and feel that is native" to the experiences on them.
