The redesign will deliver advertising associated with a user's search on the results page, with saying it has upgraded the technology to give more relevant information.
Enhancements on the site include a related search tool, "Ask Jeeves Recommends", and a picture search. Unrelated advertising will disappear and all sponsored searches will be clearly marked on the site.
Adrian Cox, CEO of Ask Jeeves UK, said: "By enhancing our core search functionality, we believe we will drive consumer usage and frequency, which is key to further developing the Ask Jeeves media platform for advertisers."
Ask Jeeves remains one of the biggest brands on the net. But as people turn to Google and other search engines, the site has had to move from its launch positioning as the simple-language search engine that allowed users to ask a question such as "Where can I buy a stereo?".
