Domain Names are an extremely important consideration in SEO.
If you’re selling used green pants, how do you think www.usedgreenpants.com or www.pants.com/usedgreen.hmtl would fare in the SERPs (Search Engine Results Page)? Well, I think you know – it would do great!
So what should we do about Domain Names, URLs and what are they?
Wikipedia’s entry on Domain Names says this:
A domain name is an identification label that defines a realm of administrative autonomy, authority, or control in the Internet. Domain names are also hostnames that identify Internet Protocol (IP) resources such as web sites. Domain names are formed by the rules and procedures of the Domain Name System (DNS).
Domain names are used in various networking contexts and application-specific naming and addressing purposes. They are organized in subordinate levels (subdomains) of the DNS root domain, which is nameless.
The first-level set of domain names are the top-level domains (TLDs), including the generic top-level domains (gTLDs), such as the prominent domains com, net and org, and the country code top-level domains (ccTLDs).
Below these top-level domains in the DNS hierarchy are the second-level and third-level domain names that are typically open for reservation by end-users that wish to connect LANs (local area networks) to the Internet, run web sites, or create other publicly accessible Internet resources. The registration of these domain names is usually administered by domain name registrars who sell their services to the public.
Use keywords as part of the domain name where possible. Purchase other domain extensions to protect the brand. Buy the .net, .org, .us, and other extensions so competitors do not. Keep URLs concise & descriptive. And ensure that the user should be able to determine where he is at based on the URL.
