A search engine to find what others can't

Start-up Dipsie is set to launch a beta of a new hosted service on Tuesday. The product, called Dcloak, is designed to show Web surfers the content in databases and on Web sites that is invisible to general search engines. Google, Yahoo and other search engines are not able to crawl Web pages of many sites, particularly online merchants and others that use cookies, page templates, forms and client-side scripts, said Jason Wiener, chief executive of Dipsie.

Palo Alto, Calif.-based Dipsie's Dcloak service automatically crawls customer Web sites, analyzes the semantics to identify relevant concepts and keywords and helps optimize pages so they will be ranked higher in search engine results. The beta service is free. After the service is officially launched in the first quarter of next year, the cost will be $29.99 a month for 50 pages or less.
