Big news in Facebook land. Starting on June 12th at 11:01pm (to be exact), people and companies using the social networking giant, will be able to create their own “vanity URL”.

What does that mean to you and me? For you, it might mean an easier Facebook address to direct people to, for me it means new search engine optimization (SEO) and branding opportunities to explore.

On The Facebook blog, Facebook Designer, Blaise DiPersia writes,

“We’re planning to offer Facebook usernames to make it easier for people to find and connect with you. When your friends, family members or co-workers visit your profile or Pages on Facebook, they will be able to enter your username as part of the URL in their browser. This way people will have an easy-to-remember way to find you. We expect to offer even more ways to use your Facebook username in the future.”

Note, new Facebookers (those who joined after May 31, 2009) and those fan pages with fewer than 1,000 fans will not be eligible. Sorry newbies!

What does that mean for SEO? Simply put, individuals and companies will be able to market their brands much easier. Did I mention that MySpace and Twitter already offer vanity URLs? Facebook has always lagged behind in this area. Very soon, individuals and companies will be able to easily share their “branded” Facebook URL. For example, in the past, finding someone on Facebook was a bit of a pain. Now people can just use your name.

See Blaise’s example:

A couple of notes, if you want to remain anonymous, you may not want your vanity URL. If your name is John Smith, be prepared for a longer vanity like www.facebook.com/JohnGeorgeFranklinSmith, unless you’re very lucky.

I suspect that there will be a mad frenzy to snatch up popular names and brands. Remember back when those sneaky cyber squatters bought up lots of great domains just to turn around and sell them for mucho dinaro? Facebook says that it is setup to handle trademark infringement cases but still, expect lots of gray areas and legal battles.

One significant thing to note, Facebookers will not be able to register generic terms like ‘houses’. I’m sure there will be a lot of people pushing the envelope on this one. Will you be allowed to select MinneapolisGreenHomes? It’s still pretty generic but it’s a specific, generic term.

Another important note, once you select your vanity URL you cannot go back and change it. Now is not the time to make a typo because you were rushed. Carefully review your selection before hitting that save button.

On a related note, Facebook’s rollout seems to coincide with speculation that Twitter is going to implode because of its inability to scale. It’s a little reminiscent of the hysteria around Y2K. Remember that? Call me a cynic, but how is it possible that this weekend is significant for the two social media giants? I wish I could believe that it’s pure coincidence but…

Be sure to remember to get your Facebook URL rockin’! As for me, I’ll be busy celebrating my son, Jackson’s 9th birthday!
