Relevant Signatories will set up and maintain dedicated searchable ad repositories containing accurate records (in as close to real time as possible, in particular during election periods) of all political and issue ads served, including the ads themselves. This should be accompanied by relevant information for each ad such as the identification of the sponsor; the dates the ad ran for; the total amount spent on the ad; the number of impressions delivered; the audience criteria used to determine recipients; the demographics and number of recipients who saw the ad; and the geographical areas the ad was seen in.
