The attribution data story is really weird here.<p>So outdoor advertisers can potentially pixel customers who see an &quot;impression&quot; like they do for online ads and track conversion behavior if they ultimately walk into a store?<p>The article doesn&#x27;t speak much to this, but what opt-in permission would a user give to actually allow their location to constantly be relayed to advertisers to make this possible? Would Target need to hide this in their T&amp;C of their app and then match it against the billboard&#x27;s data on an advertiser-by-advertiser basis...?
