I haven&#x27;t seen much on the ad data side of this.<p>Please correct me if I&#x27;m wrong, but if a publisher switches to AMP, then all of their ad serving data (and by extension impression data for all of their visitors that Google is able to identify) becomes Google&#x27;s data essentially.  Whereas before, if a publisher wasn&#x27;t running DFP, AdSense, or GA, then Google was essentially blind to their ad data.<p>So does this or does this not give Google that level of visibility into the ad layer of a site?  If so, that is a MAJOR strategic competitive data advantage once lots of sites switch over, which they will be encouraged to do due to higher mobile ranking as a result of getting their site&#x27;s sped up.
