Many social media networks enable a vanity URL to be set up in just a few clicks. A vanity URL for a private Facebook profile, for example, is automatically generated from your Facebook username, which you can edit via the "Username" option under the "Settings" menu. But be aware: With personal Facebook profiles, the selected username and resulting URL can only be changed once, so check your submission carefully.
If you are setting up a company fan page on Facebook—or if you already have one—and want to furnish it with a vanity URL, there are no restrictions when it comes to the first fan page. For every subsequent fan page however, you need at least 25 fans before you can set up a vanity URL. As with personal profiles, the username can only be changed once after the initial setup.
Twitter also generates the profile URL from the username—which cannot contain more than 15 characters—and thus also generates the vanity URL automatically. With Google+ however, URLs can be personalized. On LinkedIn, you can customize your URL as often as you like via the profile settings
Catchy vanity URLs can be integrated into your email footer, signature or newsletter as well as into your online advertisements and websites, and printed onto business cards and other offline promotional materials. Moreover, you can also use vanity URLs to neatly and professionally redirect from your own server
to your social media profile, for example by setting up a subdomain such as facebook.companyname.com or a website such as www.companyname/facebook. For 1&1 customers, the Control Panel contains brief instructions on how to conveniently link your domain with your social network profiles such as Facebook, Twitter, LinkedIn and Pinterest without creating a separate website or subdomain.
