( CNN ) -- Most parents think their children share too much information online -- and that search engines and social networks are n't doing enough to protect privacy , according to poll results released Friday . More than 90 percent of the parents surveyed by Zogby International said they are `` concerned '' that their children share too much information online , and 75 percent said they would rate the job social networks are doing to protect online privacy as `` negative . '' The results , released by the nonprofit advocacy organization Common Sense Media -- which commissioned the poll -- do not mention particular social networks or websites by name . Common Sense Media CEO James Steyer said the need for reform is clear . `` Parents want far more education and leadership about online privacy , and they clearly want the industry and the federal government to update privacy policies , '' Steyer said in a statement . The organization begins a campaign Monday aimed at protecting kids ' personal information and reputations online . `` We need a 'Do Not Track Kids ' approach ' similar to the 'Do Not Call ' policies that restrict telemarketers , '' Steyer said . The results also include a survey of 401 teenagers aged 15 to 18 . Common Sense Media said 79 percent of the teens surveyed also think their friends share too much personal information online , and 85 percent of them want search engines and social networking sites to ask for permission before using personal information to market products . `` The poll results present a clear divide between the industry 's view of privacy and the opinion of parents and kids , '' Steyer said . To conduct the online poll of parents , Zogby International used a sampling of 2,100 adults from its online panel , which the polling firm says is representative of the adult population of the United States . The sampling margin of error is 2.2 percentage points . The sampling margin of error for the online poll of teenagers was 5 percentage points .
