Listing Categories on each page versus in the drop-down navigation; which is better for SEO

[TopFloor]

My client, www.warehouse-lighting.com, has all the links to its category pages on a left-side navigation structure.  Their competitor, www.prolighting.com has all of its category-page links listed under the drop-down menu of the top-level navigation.  I’m wondering if one way is better than the other for SEO and why?

I don't use drop-down menus because some people will not see them.  I would rather have all of my navigation links out there and visible to the visitor.

If you want to know for sure you can run a simple text and see what delivers the  most action.

Just keep it as it is, the change isn't worth the decrease in usability. Plus, things like this usually don't have any significant impact on SEO. However, you should really work on improving the homepage, it's too cluttered and doesn't look very good either.

Thanks for your replay Marko.  I agree that the home page needs a lot of work.
