August 1 news, "Fortune" magazine wrote that unless Cuil develops an advertising platform comparable to Google's, it will be difficult for the new search engine Cuil to become a rival of Google. Author Yi-Wyn Yen said that comparing Cuil with Google is inevitable. Cuil was developed by several top engineers from Google, including Anna Patterson, who developed Google's TeraGoogle indexing system. In addition, Cuil claims that it can search 12 billion web pages, three times as many as Google. Moreover, Cuil's simple start page is very similar to Google's minimalist home page.
