Google plans to update its AdSense program policies to prevent placement of its ads on sites distributing fake news.
Facebook also said Monday it had updated the policy for its Audience Network, which places ads on websites and mobile apps, to explicitly clarify that it applies to fake news.
“In accordance with the Audience Network Policy, we do not integrate or display ads in apps or sites containing content that is illegal, misleading or deceptive, which includes fake news,” Facebook said in a statement. The company said its team will continue to closely vet all prospective publishers and monitor existing ones to ensure compliance.
False news stories have become a sore point after the U.S. presidential elections with critics blaming internet companies like Twitter and Facebook for having had an influence on the outcome of the elections as a result of the fake content.
