Welcome to WebmasterWorld Guest from 220.127.116.11
The navigation appears on the bottom of every page, with the exact same links on each and every page.
So we got all information about the page at first, and beneath the page contents we currently have our entire navigation (drop down menu) listed in plain text followed by links. The navigation includes most of our keywords and anchor text to that specific page as well.
Would this be of any problem to Google?
We have moved all links to the very bottom of the page.
However, each and every page has the same 100 links that are included in our drop down menu..
Should I be concerned?
Our site is in supplemental results, could this be the cause?
There is another underlying cause for going supplimental. You may have duplicate content ... or at the very least similar content, or you could have the same title and description on the page. Without knowing your url i'm just throwing out some guesses.
Have you made sure someone hasnt copied your content? Are you using manufacturer descriptions?
