This contribution by breakmyzencart.com changes the way URLs are generated by Zen-Cart. Instead of referencing the destination page in parameters, meaningful paths and filenames are created. This helps getting your site indexed by search-engines faster if you have content that is worth indexing and feeds it with keywords to increase your page rank. Compare the following URLs and see for yourself.

Installation and configuration instructions are included in the downloadable contribution available at http://breakmyzencart.com/sefu or at the SEFU documentation page.
