Altering navigation tabs

I am looking to modify vB to add a number of tabs to the navigation bar (much like the "Buy Now", "Support" and "Download" tabs here). My concern is about the various hacks that are available at vbulletin.org interacting and interfering with vbSEO in any way.

Do you recommend any particular approach to adding tabs in a way that (a) does not interfere with vbSEO and that (b) is good from a SEO standpoint.

Thanks,

-Martin

The best way is to do a template edit, or use a template hook via your own plugin. We don't have any expereince with .org mods and cannot attest to their quality or compatibility.
