Did internet ad fraud con advertisers? Direct clicks and conversions are such lowest common denominator crap. Suitable for ponzi schemes and snake oil sales. Tesla advertises amazingly well online. Their conversion rate is clearly zero. Not close to zero, not "they don't care" It is zero, nothing, not one single conversion.

Across the breadth range of companies built on advertising from coca cola to chanel as far as I can see they don't use internet ads. These companies have not gone away. Google, Facebook, ebay etc etc all have poster ads in my town. I guess targeted internet ads didn't work for their purposes.
