Site Navigation is an important consideration in SEO.
The first step is to think about Usability. Always think about your visitors first; we’re not just wanting to be found via SEO – but we primarily want to increase revenue, or somehow convert.
With that in mind…If the site uses Javascript drop down menus, Flash, etc., for navigation, it’s be sure to create alternative text links for the Search Engine spiders, users and text-browsers to follow.
PageRank is an important consideration in SEO, however don’t get caught up in it.
PageRank is just one small piece of the SEO puzzle, being a Google-specific link analysis algorithm in its own right.
Google explains PageRank in their Technology Overview, as well as the life of a Google Query. This makes for great reading, and will help you grow your SEO understanding. I highly recommend checking it out.
So yes, PageRank is a factor in your SEO efforts, but it’s definitely not everything. Understand what it is – perhaps even track it – and then move on, to more important on-page and off-page SEO factors.
The two types of links we’re concerned with today are those on a page of your site pointing to another page on your site, and then there are those links from other websites pointing to a page on your site.
Links to your home page should obviously be found pretty much all over your site; on every page. Perhaps linked from your company logo in the upper left, and or in your main navigation, as well as in your footer. We know that links are an important consideration in SEO.
Go through and take a look at how you are linking to your home page throughout your site.
