The importance of having a good domain name is that if you want your website
, product and services to be successful then having a good domain name should be top of your to do list.
The product or service that you are doing will have to be around your domain name in some way for instance if your website is about gardening and you have a name which is about fishing then you will have problems with traffic, so have your domain name on the same line as your site.
6 months old What you should look for when you are going to buy your domain name is to try and get one, which is over 6 months old, and you will be able to get a good check done on it.
Keyword rich The domain should be short and keyword rich in other words try not to get a long domain name that is hard to pronounce and not brandable.
Indexed in Google You will want to make sure that the domain name that you buy is not banned, blacklisted or sandboxed by Google. To find out about a name you might be interested in go to Google.com and enter the search term below. Site:http://domainname.com As long as the name shows up in the listings you will know it is indexed.
Page rank This is another very important part of your domain name as Google ranks a score to each page and it ranges from 0 to 10 (the higher the better).Ideally you should for a page rank 3 to make anything from your proposed site, but starting off with 1 and 2 is still not a bad start when you are just starting out.
Valid When you are buying a name you will have to make sure it is valid so double check the name and you could use the below tool.

Traffic Any name that you go for you will want it to attract traffic and we all know how that is important to your business, I would also put it through the alexa ranking for your site and that way you will have a good double check.
Domain deals So where do we go to find domain names, I would look in Ebay just enter the search term "domain names" and click search. Now what I have found in the past is some people selling the domain names do not know the real worth of some names so you could pick up a bargain. So with what I have told you about domain names go now and get one.
