Google has added another URL shortener to its arsenal and this time, it’s in the form of g.co. If you are familiar with Google’s other URL shortening service, goo.gl, you may be thinking to yourself, what is the difference between the two services?
Well, the older goo.gl service which was launched in 2009 allows you to shorten any web url, regardless of the domain and it is available through the Google Toolbar if you have this feature installed on your browser.
On the other hand, the g.co will be limited in use to Google only. When you see a url that has been shortened using g.co, you will know that the link will redirect you to either a Google page or a Google service. Additionally, only Google employees will be able to shorten urls using the g.co shortener, it will strictly be an internal redirect service.
As Gary Briggs said on behalf of Google, when you see a link that has g.co in it, you can be quite confident that the resulting page will be a safe page that will not lead you to either spam or porn. Google is not the first company to make the move towards a .co domain extension as it was last year that we saw Twitter scoop up the name t.co for their own URL shortener.
