It is important for Search Engine Optimisation that you have incoming links to your website from other webpages on the internet. Links give the search engine important information about your website, so the placement of the link matters.
As we have discussed before, links are like recommendations from other websites. If these inbound links arrive at many different pages on your website you will tell the search engine that many different sites believe that your entire website is full of worthwhile content.
If, however, all your inbound links always arrive at your homepage, the search engine will be under the impression that your website is shallow, with little to offer, or that your links were generated by automation rather than the value of your site.
