Some years ago, an article started showing up in news feeds from a seemingly skeptical investigative reporter who claimed to have tested the efficacy of an acai berry–based colon cleanse. Posted on a website called onlinenews6, the reporter’s article claimed she lost 25 pounds in only four weeks.
But the website was not owned by a legitimate news organization, and the reporter didn’t exist. Instead, it was part of a deceptive promotion by a company that was selling the acai cleanses and hoping to profit off of consumers’ trust in objective news.
Long before US president Donald Trump brought the phrase fake news into the mainstream, the Federal Trade Commission used it to justify shuttering 150 websites from 10 companies that made “false and unsupported claims” and deceptively represented their websites as objective news. Chicago Booth’s Anita Rao finds that not only do these types of fake news websites change readers’ beliefs about the products they deceptively promote, but they can separate consumers from their money.
While “native advertising” can often mimic legitimate news and is considered legal so long as it is properly identified, the FTC determined that these 10 companies’ pitches—selling mainly weight-loss supplements, colon cleanses, and natural diet supplements—conveyed “to consumers expressly or by implication that they’re independent, impartial, or from a source other than the sponsoring advertiser―in other words, that they’re something other than ads.”
Rao, who has previously analyzed false claims about products, examined 2010–11 data―before and after the FTC action―from Comscore, a media measurement and analytics company. Comscore tracks, at the domain level, browsing and buying behavior of 100,000 internet users across the United States, and its data set is based on a random sample drawn from a cross section of more than 2 million global internet users. Rao analyzed referral domains to see whether potential customers still went to a product page after the FTC shut down fake news sites. She finds that after the sites were closed, visits to their related product sites such as acaireduce.com dropped between 6 percent and 15 percent.
