Google is requiring those placing political ads during the upcoming US elections must prove they are US citizens or permanent residents.
This is just part of an update to its policies that tries to make political adverts more “transparent”.
In addition, advertisers must reveal who given the funds for the advert.
Social media firms have updated their policies in the wake of revelations that their ad platforms have been abused by Russian propaganda tactics.
Google’s new policy comes after changes at Twitter and Facebook on who can buy space for political adverts.
