Search engines use the relevance of your site to determine it’s value in their algorithms. As your site ages, it develops links to other websites and grows internally. It is just as important to use your internal pages to develop what is known as deep linking as it is to have similar websites linking back to you.
As each page is added to your site, use a slightly different set of keywords, but maintain at least one central keyword that is valid on every page of the site. Ordinarily, your domain name will be keyworded as well, and should always be associated with similar products and services. This branding at its most basic, and building domain relevance at its most complex.
For example, If your domain is www.perfectcopy.com, and your website is focused on delivering web content, reviews, articles and other copywriting services, you will want a main page which mentions everything you do, and will be keyworded to uniquely identify those services. From that main page, you will link to individual pages on the site, which may in turn be focused on each service. This allows you to build your site relevance, and has the added benefit of explanding your relevant keyword base.
After all, a domain is more than a web page, it is a site built to serve a particular need in the community it is addressed to, and should be well managed to enable people to find it using a wide variety of possible searches.
