From Kathy (fixing formatting email issue): > Hi Rob, > > Answer to Q1: > The same identifier(s) will be used on ads on multiple sites, (e.g. campaign_id and creative_id) will usually be present on all sites, since it is the exposure to that piece of content that is being measured in systems designed to measure ad reach and frequency. > > If the question is about tracking an identifier across multiple websites so that it would be possible to display an ad to that user/browser again on a website, other than the one on which the identifier was first recognized, this does not apply since the normative description of audience measurement research specifically rules this out. > > Answer to Q2: > Although it is not entirely clear how to define aggregate scoring, if it is similar to the activity described in Peter Swire’s note to the W3C group, i.e. so that a company could keep andupdate a user profile linked to a unique identifier, so long as the specific URLs seen by the user were discarded, this is to confirm that Issue 25 excludes this additional use of the AMR data. > > Regards > > Kathy Joe
