When performing a site architectural review, one of the first things I look at is the site’s main navigation elements. This includes top, side and footer navigation. Together, they all play an important role in both the ability of the search engines to properly spider your website, as well as allowing your visitors to find important areas and information quickly and efficiently.
Site navigation can come in many different flavors. There isn’t just ONE way to do it correctly. If there were then every site would have navigation that looked exactly the same. So while navigation can vary greatly between sites and industries, there are certain navigational elements that should be implemented to ensure solid usability and effective website architecture.
