People are using Twitter more then ever before. According to compete.com Twitter is getting around 24 million unique visits per month. Twitter is being used by many personal and commercial sites in order to drive people to their content. If you’re using your twitter account to market yourself or your services, then it is extremely important to utilize the background image as a way to market yourself. Many times it can be as simple as including your contact information on the left hand side. Best Buy even uses it in their marketing of Twelp Force through their twitter account http://twitter.com/twelpforce.
You can create the image yourself or utilize a company that specializes in professional custom twitter backgrounds. I personally used Twitter Backgrounds to make mine and was very impressed with their level of service. Twitter Backgrounds will allow you to revise your background up to 3 times, but in reality they’ll do it until you like it.
The long and short of it is, that don’t overlook the power of social media and what you need to optimize it. It’s not as simple as just blasting links to your site, but once you get the hang of it, it can certainly be a huge driver for you.
