Last week Facebook announced that they would now be placing Facebook advertisements on Facebook pages. Previously these pages were served up ad free but all of that will change soon. So what does this mean for the average advertiser? Well, simply put, Facebook has just increased their ad inventory by millions of daily impressions.

According to Facebook’s statistics, “more than 3.5 million users become fans of Pages each day.” Currently we are tracking a large portion of that growth through our Facebook page statistics tool. This is a small change by Facebook but it’s a quick way for the company to boost revenue by a relatively substantial amount (somewhere around a few million dollars annually).

As Facebook states in their announcement, “the enhanced distribution is based on the audience you have selected when you created your ad, not based on the content of that Page.” It would be interesting to see adds targeted by your affiliation with fan pages though. While Facebook continues to try an increase their revenue through small changes like this one, the company is much more focused on sustaining the record-breaking growth they continue to experience.

Over the coming months and years I would expect that businesses become more savvy about advertising on Facebook just as they became educated about advertising on Google. The ability to target by profile data is clearly a huge value ad. Currently the company makes less than an estimated $200 million annually from their self-serve advertising program.
