When visitors come to a dealership site, most dealers should want them to figure out how to navigate it quickly. Therefore, most websites have a navigation area ("menu bar") at the top or side of each page that stays the same and contains links to other areas of the site. Referred to by SEO experts as internal linking, this is incredibly relevant for SEO because every link in the top-level menu will rank better than pages further down in the navigational set up of the site.
To a search engine, top level menu links look like every page on a site is linking to the pages referenced. One way to take advantage of this is to cross reference important keywords with site categories and making sure that pages that need to be ranked highly in search engines are linked to in the main navigation of the site.
Another way to use site navigation properly is to identify what pages get the most traffic and making sure that they are easy to find via the menu. This will in turn show a lift on the already popular pages, driving up the SEO relevance even further.
Finally, one should examine exit pages and make sure that they are accessible in the menu as well. If clients are coming to a site looking for directions, phone numbers and/or a contact form, these should be easy to get to via the site navigation. This will help clients have a more intuitive visit on a site and increase chances they will return.
Site navigation seems to be used on every website, but many underestimate the user experience and SEO potential to be provided via internal linking. How are you all molding your site nav to best benefit SEO and user experience?
