Fair enough, there is a lot of wasted ad spend but a lot of it is accurately targeted. I work sales/biz dev in the digital marketing industry, so I do know all the pros & cons and many ads aren’t aimed at efficiency and optimization. I just billieve the fall of Deadspin had little to do with the ads on their site and more to do with the content. If valuable users regularly visited the site, the ad space would be much more expensive and the junk ads wouldn't afford to bombard the sites users
