Google Experiment Results: The Power of Navigation Links

In our continued coverage of the a WebmasterWorld thread started by senior member CainIV, we learn two more things. These two items are likely obvious to most, but have been confirmed (at least to CainIV) that they are true based on his experiments.

  1. Changes to navigation links can have a serious impact on a site's ranking in Google. CainIV said, "there are certainly nav and footer link thresholds that cause a website - even a website into the top 5 - to spin out and down to pages 5 and 6 in ranking."
  2. Navigation links are treated differently then links within the content. CainIV said, "Google appears to handle thresholds from links within content different than those within nav or footer sections - this is to say, that content links have a fuzzier 'trust' logic about them, and I could more links to content, faster and more focused on the primary keyword pointed at the root url without the same threshold being crossed."

Like I said and like CainIV said in the thread, this is likely all assumed already but can't hurt to validate it.

I believe navigational links are powerful not because they are 'navigational links' but because of their position/placement on a site. A spider usually crawls a page from top to the bottom and links that are placed high above on a page certainly has higher authority over the other links that are placed in less important places (e.g. sidebar, footer etc.)

It appears to be a very poorly defined test. It really doesn't cover anything new and doesn't add any value to the SEO experience.
