There is much discussion in these last few months about reciprocal linking. In the last Google update, reciprocal links were one of the targets of the search engine's latest filter. Many webmasters had agreed upon reciprocal link exchanges, in order to boost their site's rankings with the sheer number of inbound links. In a link exchange, one webmaster places a link on his website that points to another webmasters website, and vice versa. Many of these links were simply not relevant, and were just discounted. So while the irrelevant inbound link was ignored, the outbound links still got counted, diluting the relevancy score of many websites. This caused a great many websites to drop off the Google map.
Make it as easy as possible for users to go from general content to the more specific content they want on your site. Add navigation pages when it makes sense and effectively work these into your internal link structure. Make sure all of the pages on your site are reachable through links, and that they don't require an internal "search" functionality to be found. Link to related pages, where appropriate, to allow users to discover similar content. Denver Page Rank Click Here
