On Monday, the top trending story if you searched Google for “final election vote count 2016” was a fake story on a site called 70News claiming that Donald Trump had won the popular vote, even though he had not. And in the week before the election, Facebook and Google were being criticized about fake news on their sites, which critics believe could have swayed the presidential race’s outcome.

Google responded Monday with a pledge to restrict fake news sites from using its AdSense advertising network. Facebook, for its part, updated its policy to clearly state that its advertising ban on deceptive or misleading content applied to fake news.

“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. And Facebook chief Mark Zuckerberg on Saturday tried to put the kibosh on the idea that Facebook’s platform influenced the election.
