I typed in a short, catchy, three-word domain name that I wanted into godaddy's domain name checker and to my surprise, it was available.
I didn't purchase it there and then because I wasn't 100% sure if I wanted it. I figured that because it looked like it had never been registered before (Server not found page was displayed) it would probably be safe for a couple of days.... Big mistake!
the next day I tried to register it only to find that www.widgetworld.com and www.widgetworld.co.uk had now been registered -Bugger!
I'm pretty sure that the names were registered as a direct result of me typing in www.widgetworld.com into godaddy's checker (thus alerting "someone" that www.widgetworld.com was a good idea for a domain name.)
only a few days ago, I checked the status of www.widgetworld.com again and was even more surprised to find that it was available again!
so within five minutes I owned
www.widgetworld.com
www.widgetworld.org
www.widgetworld.net
However, I could not get hold of www.widgetworld.co.uk, this had been registered by a company that had a website selling a very similar product to mine!
so should I be happy that I will get a small percentage of their traffic (I guess people invariably try .com first) or should I be concerned about not having a monopoly?
Yet it is normally in the interest of you, the competitor and the user that tha latter one ends up where he or she wanted to go in the first place.
If it is a good domain, forget about co.uk.
