Google has this great tendency to experiment. They change things and then let us know a few days afterward. It appears that they are looking to compete with even more of the little guys and their ideas now.
Google has joined the ranks of Bit.ly, digg, and many others with their URL shortener. Aptly, their page is at http://goo.gl.
The short URL has really changed how we do SEO in the area of linkbuilding. Linkbuilding is simply getting links to your site on other sites. This can be done in many ways, blog comments being very common.
With the advent of Twitter (i.e. “a little bird told me”), mini blogs exploded. Facebook definitely contributed too. And social media was born! We found ALL of our friends! Then we shared cool links with our friends and business acquaintances. Why not share our new stories too?
Sharing our stories, posted on other sites of course, with business associates is really where social networking for SEO was born. Now we can share posts like this one with everyone we know in seconds. But who is really going to shove “http://tehchad.com/seo-google-entered-short-url-market/” into a tweet? When you’re limited to 140 characters, a URL like that is just too long. Ergo, we use things like bit.ly and goo.gl.
