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.
However, I was planning on adding this menu to every page on the website via an ssi tag and by putting it in the header for agoracart. FYI, the menu is css with only a very tiny bit of javascript to allow the menu to stay open when your mouse is not on it.
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.
Thanks
Steve
