The study isn't published yet so I withold my judgement. Given that the results are beneficial to people selling adverts caution should be exercised. (Two of their big problems are that click through rates are abysmal and many people dislike ads. They benefit if advertisers believe they achieve "additional sales".) EDIT: FOLLOW UP. I had a deeper look. The article is dated, "Posted in Business on February 3, 2017". I found one copy of the paper published December 29, 2015 and another July 26, 2016. Both same I think, but one author had moved from Google to Pandora. The article text seems off beam. The paper describes a method to better estimate advertising impact, not directly what that impact is. Odd.
