Use intra-linking for better Google page rank. Just having your website links in the navigation system is not enough. Having links within the content of your website pages which link to other pages on your site is called intra-linking. This process, along with some article directory listings, bookmarking, and directory back links will result in many of your site pages having a page rank value of one to two. When I see a new client site that has zero page rank value I know they have not done a proper intra-linking and other free back linking methods available. Interlinking is a simple process and should be done every time a new page is created on your site. When I create a new page on my website, I always open up a few other pages that are related to that pages topic and create some links linking back to the new page I created. Likewise, on the new page I created, I always create a least one point to another page somewhere on the site. Interlinking is one of those steps required for good search engine optimization. Intra-linking is valuable for achieving an initial page rank with Google.
