Don’t Nest Your Pages

When Google crawls your site, it typically starts at the home page and then follows each link on the page to all your other pages. Google finds your home page in turn from following a link on another website that points to your site.

Generally speaking, Google seems to attach more importance to files that are closer to the root folder on your server - the folder on your Web server where the home page file is located. Bear in mind however that some web designers may create multiple folders on the server for ease in maintaining lots of files.

It is believed that Google assigns pages located in other folders a lower score than pages located in the root folder. In general, Google doesn’t like to index sites that are more than about two folder levels deep. Ideally, all pages should live in the same folder as your home page or at most be one level deep.
