A parental advice Internet site has sued Google Inc., charging it unfairly deprived the company of customers by downgrading its search-result ranking without reason or warning.
The lawsuit notes that rival search systems from Microsoft Corp.'s MSN and Yahoo Inc. feature Kinderstart.com at the top of their rankings when the name "Kinderstart" is typed in.
The complaint accuses Google, as the dominant provider of Web searches, of violating KinderStart's constitutional right to free speech by blocking search engine results showing Web site content and other communications.
The suit was filed the same day a federal judge denied a U.S. government request that Google be ordered to hand over a sample of keywords customers use to search the Internet while requiring the company to produce some Web addresses indexed in its system.
