Out of an estimated 100 million internet users, there may be thousands looking for your Web Site every hour of the day. If your Web Site does not come up in the top 20 results on at least a couple of major search engines, you are missing customers that are looking for you, and losing sales. For the most valuable publicity available on the Web, there is one most effective strategy. Arrange a domain name with your most desirable keywords. The new 67 character limit makes this possible.
All search engines prefer domain names that contain the searched for words.
Now that their exclusive government contract is ending, competitors have tossedthis artificial limit and are allowing longer names. I did some digging into the original name space RFC to assure myself that the longer names were valid. They must start with a letter, end with a letter or digit, and have as interior characters only letters, digits, and hyphen. There are also some restrictions on the length. Labels must be 63 characters or less.
