Ask.com is betting it will. The fourth-largest search engine company will begin a service today called AskEraser, which allows users to make their searches more private.

Ask.com and other major search engines like Google, Yahoo and Microsoft typically keep track of search terms typed by users and link them to a computer’s Internet address, and sometimes to the user. However, when AskEraser is turned on, Ask.com discards all that information, the company said.

Ask, a unit of IAC/InterActiveCorp based in Oakland, hopes that the privacy protection will differentiate it from more prominent search engines like Google. The service will be conspicuously displayed on Ask.com’s main search page, as well as on the pages of the company’s specialized services for finding videos, images, news and blogs. Unlike typical online privacy controls that can be difficult for average users to find or modify, people will be able to turn AskEraser on or off with a single click.
