I just checked out the first one posted by the OP. Very clever. They state that to get listed in their directory you must have a .us domain name and they give you a link and show the many domain sellers where you can purchase a .us domain name from. Wonder if they are affiliates of all of them. If so, very clever indeed!
Very cool idea, think I'll go do something like that. I already have some local city domain names, however, I like the zip code idea.
What do you all think is better? Get a zipcode name with .net, .biz, .info, or .org since the .coms and .us is not availalbe. OR get a zipcode+someword.us?
Please give opinions and why you feel this way.
Since the .com's are all taken and very unlikely to get type-in traffic on other tld's anyway, I say may as well go for the zipcode alone under any tld you can find it. However, may be clever use of a .us to use zipcode and a short keyword in your niche?
