In my opinion, URL’s are digital real estate because once they have been reserved, they’re gone! To keep your websites/blogs as streamlined as possible it’s no longer enough to see if your URL is available only for your website. I recommend to my clients to check their URL with LinkedIn, YouTube, Twitter and Facebook as well BEFORE they purchase their domain.
For example, lets say your new website idea is “MyBusiness.com” and let’s pretend that specific URL was available for purchase. Before you purchase it, make sure you go to Twitter first and see if “Twitter.com/MyBusiness” is available too. Then, go to Facebook and see if Facebook.com/MyBusiness is taken and so on. If you can find the right wording or phrasing that is not only available for your main website, but also available on various social media networks, it will create a clean, simple and familiar brand online across your various networks. It will also make it easy for people to find you on those networks.
If the URL you’re desiring doesn’t bring anything up on Facebook and Twitter, it doesn’t guarantee that the URL is not reserved, but the odds are definitely good if nothing loads up on the page. I would check in this order: Facebook, Twitter, YouTube then LinkedIn. If it looks like the URL is available, create it on Twitter and YouTube first. Once you see that it’s available, then go ahead and purchase your main domain URL. Facebook is tougher, because even if the URL doesn’t show up initially, it doesn’t mean that someone hasn’t reserved it necessarily. You will have to wait until you have launched your page and attained 25+ Fans before you can confirm the availability.
May I make another suggestion in regards to your choice of URL? I recommend doing your best to find a URL with .COM (as opposed to .ORG, .NET, etc). People are more familiar with .COM and usually assume that’s where your website is at. I have been involved with a .ORG website, and many people typed in our URL after hearing about the website from us, but then ended it with .COM and had trouble finding us.
The simpler you can keep your various URL’s, the stronger your association between your brand and your social media sites you will have.
