"The “first link priority” rule is Google’s way of making sure a webmaster doesn’t add hundreds of anchor text links into the content of their website."
Basically, when the search engine spider crawls a page on your website and comes across two links pointing to the same page, it will only consider the anchor text of the first link and disregard the second. While this rule has been well documented by many SEOs, there seems to be some confusion on whether or not this rule applies to the navigation menu of a website.
