Ever wondered which musician has the fastest growing Facebook Page? Or what TV series? A new beta service called SocialMedia-live is tracking the growth rate of 38 million Facebook Pages, with 2 million of those available to view. It has statistics on total number of likes, fan growth, interesting newcomers and male/female breakdown. These statistics are categorized and users can create comparison graphs. The bad news is that there is no apparent search function.

The answer to the first question, by the way, is Adele, who gained 175,000 followers over the last 24 hours (at time of writing). Adele's popularity on Facebook is mainly due to her female fans; 62% are female and 38% male. The fastest growing TV show is Mob Wives, perhaps thanks to the current "swear jar sweepstakes" promotion on its Facebook Page. This type of data is useful, albeit limited at this point.

A sister site called Likes Matter offers a real-time view of Facebook Page growth rates. There I discovered that Eminem's Facebook Page is currently attracting about 35-40 new likes every minute.

The main site, the awkwardly named SocialMedia-live, updates Facebook Page data on 90,000 "big players" every 10 minutes - including Eminem, Coca Cola, YouTube and other very popular brands. A further 1.8 million "medium-sized pages" are updated every 12 hours. The other 36 million or so "little pages" are refreshed every 5 days.

There's a special page for "Hip Fanpages," those Facebook Pages "that have distinguished themselves in terms of layout, navigational ease, interactive fanpage features, etc." Current members include Adidas Originals, Snooki, Livestrong, Star Wars and a German comedian named Linda P. That last pick is a clue that SocialMedia-live hails from Germany.

There are some useful comparison tools, too. Below is a chart comparing the growth of Adele, Jennifer Lopez and Katy Perry over the past 90 days. We can see that the popularity of Adele's Facebook Page spiked in January of this year. She has about 12.6 million fans at time of writing. Meanwhile Lopez is growing faster than Perry. Although note that Perry has more fans than Adele and Lopez combined. She has 37.6 million fans, while Lopez has 8 million. A likely explanation is that Perry is much nearer to peak popularity on Facebook than either Adele or Lopez. Growth rate could also be affected by when the fan pages were started. So, as always, take these statistics with a grain of the proverbial salt.

The big thing missing from SocialMedia-live is search. I could find no way to get statistics about our own ReadWriteWeb Facebook Page, for example. There also seems to be no easy access to the 36 million or so "little pages." Both of those issues severely limits the usefulness of the site for marketers, who would be a prime audience for this data.

But this is a beta site, so we hope it will expand over time. For now, if you're interested in finding out how fast certain brands are growing their Facebook Page fan bases, then SocialMedia-live offers an interesting set of statistics.
