It used to be that Flash-based cookies were pretty solid, but now there’s no more flash...

What matters to ad campaigns is lift and not accuracy. What about conversion attribution? Don’t you need cookies for Amazon/etc to figure out what website led you to a purchase?

What the article lacks is a breakdown of who the ad buyers are. In particular, there’s probably a big difference between today’s Facebook vs display ad buyers (especially vs 5 years ago).
