Scott Messer is founder of media advisory firm Messer Media and former svp of media at Leaf Group. Scott is in the weeds on the digital ad ecosystem, and he broke down the current state of play for publishers. We discussed why traffic declines are still the No. 1 challenge for publishers, why publishers are shifting from traditional monetization mechanisms, retail media as potential allies, and why “curation” is the latest hot new trend in ad tech, even if it sounds quite a lot like what ad networks have always done.
