Twitter said on Tuesday that it would bring more transparency to advertisements on its site, including political ads, in the latest response by a technology company to criticism about its role in spreading foreign propaganda during the 2016 presidential campaign.
The company said that under its new rules, users would be able to see who had created an ad, how long an ad had been running and how the ad was targeted toward a particular user.
Political ads for a particular candidate or party would carry a special label to make them stand out. Twitter said it would disclose who had paid for the election advertisement and allow users to find information about the buyer, including ad spending history and ad targeting practices.
Twitter said it would also create stricter requirements for who could serve political ads. The company said it would also limit targeting options and create stronger penalties for violators.
Twitter’s announcement highlights the increasing pressure on social media companies. Twitter, Facebook and Google are scheduled to appear for congressional hearings on Nov. 1 about the role their sites played in Russian’s attempt to influence the 2016 presidential election.
Lawmakers like Senator Mark Warner of Virginia, the leading Democrat on the Intelligence Committee, have expressed frustration about Twitter. He has said Twitter was not fully cooperative when asked to provide evidence of Russian-linked advertising and accounts that spread misinformation or were used to favor a particular presidential candidate.
