Site Architecture in SEO
Your site architecture is the structure of your website; the way you organize your information. When building site architecture, the main focus is on your user, of course. However, website architecture is a critical component of SEO. To improve your SEO ranking, your site architecture needs to focus PageRank on the most important pages or the pages that generate the best profit margins.
Good website architecture helps search engines categorize your content. It also allows you to funnel link equity through your site. Inbound and outbound links on each page to support the hierarchical structure of a website promoting the most relevant pages to users. It also can strategically increase the value of most commercial pages.
Through proper site architecture you distribute the link authority throughout the website, starting from your home page. Your home page is most likely the most popular page on your website. Its link value (PageRank) is split between main navigation links and other links leading from the home page.
As you move deeper into your website, there is less and less link authority to go around. Think of it like a champagne pyramid - you pour one bottle of champagne into the top glass (your home page). Not all of the liquid will be distributed to the bottom layer of your glasses. To make sure one of the glasses important to you at the bottom of the pyramid gets filled, you could re-direct natural flow to go to that glass directly.
