Clickable keywords and SEO

A friend pointed out that our competitor websites have clickable keywords on the product pages. Well, I was going to add this feature some time ago anyway, so today I finished it. Now we also have clickable keywords, only better then our competitors. Besides, this seems to be a good thing for Search Engine Optimization. Especially, when keywords go to static pages instead of dynamic pages. Try this page 3D model of a car rim and click on keyword tire. What will happen is that you will be transfered to the page http://www.exchange3d.com/cubecart/3D_catalog_tire.html which looks like a static HTML page. Thanks to apache mod_rewrite tricks!
