A system and method for optimizing the rankings of web pages of a commercial website within search engine keyword search results. A proxy website is created based on the content on the commercial website. When a search engine spider reaches the commercial website, the commercial website directs the search engine spider to the proxy website. The proxy website includes a series of proxy web pages that correspond to web pages on the commercial website along with modifications that enhance the rankings of the pages by the search engines. However, hyperlinks containing complex, dynamic URLs are replaced with spider-friendly versions. When a human visitor selects a proxy web page listing on the search engine results page, that visitor is directed to the proxy web page. The proxy server delivers the same content to the human visitor as to the search engine spider, only with simplified URLs for the latter.
