I've been working on a web site menu update and I would dislike doing anything that might mess up my google keyword rankings for individual pages.
This update is going to involve a new menu system. Currently the only full menu is on my index page. ie www.budgetlighting.com It's nothing fancy, just a bunch of links, but it works.
What I would be changing to looks like this ie. www.ballastlighting.com/index-test.html The links are all in the menu on the left, still not a big deal.
Any guess as to the what a menu (the same menu) on every page might do to current individual page placement in google?
The more I think about it the more I'm inclined to just have the menu on my index page and the agora index page (with a different header so it only appears once). That's the way the site menu is now but just in a different format.
I would like to have the menu on every page but..... If it doing so would have a negative effect I would not. I could possibly add the menu on each page by using an iframe instead (if that would be noticed less by the search engines).
Just looking for some input.
