Deep linking is very useful

Make sure you have links coming in to as many pages as possible. What does it tell a search engine when other web sites are linking to different pages on your site? That you obviously have lots of worthwhile content. What does it tell a search engine that all your links are coming in to the home page? That you have a shallow site of little value, or that your links were generated by automation rather than by the value of your site. Here is an example of deep linking, in this case to my personal happiness workbook.

Deep linking is very important but first of all we should focus on our home age and after that we should focus on inner page. If our inner page rank will be well along with our home page then it will be helpful to increase our site traffic and popularity.
