Since the botched IPO, Facebook has been working feverishly on creating enhanced ad offerings. According to Clickz, the most traditional form of Facebook ads will be adding rotation to the mix. Currently ads are static on a page and aren’t swapped out until the user hits a different page.
This makes quite a bit of sense for Facebook. Facebook ads typically get noticed and are clicked quickly, or are bypassed for good. Having the ability of displaying multiple messages should increase the click to pageview percentage on ads. An overwhelming majority of advertisers only use pay-per-click pricing on ads, so there should be no need to work or tweak campaigns based on this change.
