We characterize the effect of fake news on online browsing during the 2016 US presidential election. We estimate that weekday increases of 10 fake news articles — that were confirmed to be false by third-party services — increased the incidence of fake news site visits by 3.0%. To address endogeneity, we employ two approaches that attempt to isolate exogenous variation in fake news supply. We also estimate that weekday 10-article increases in fake news increase the odds of visiting one or more fake news sites by 3.7%. Overall, this evidence demonstrates the effectiveness of fake news production in reaching a diverse set of consumers.
