What do we really know about the effectiveness of digital advertising?
Great to see an article like this. This subject is almost suspiciously under-researched by journalists. There &#x27;s definitely something rotten in  the promises that internet advertising has become somehow more effective. If that were true, wouldn&#x27;t businesses notice? Wouldn&#x27;t they spend a bigger part of their revenue on ads ? Wouldn&#x27;t that return even bigger ROIs? Yet businesses spend roughly the same for over a century in ads, and it&#x27;s not like the 2000s-2010s were the period of massive growth in consumer spending.<p>We need more of this research, please, because advertising is a huge deal for the health of the internet, despite its vilification. And it doesn&#x27;t  begin and end with FB+Google<p>Also: It would be nice if people who comment here  and work for Google or FB declared their conflict of interest
