The Death of the Click (axios.com)
Sara Fischer, writing for Axios: For the past 10 years, we've operated on the premise that the most important digital metric is the click that refers a person to a website. That click usually comes from a social distribution channel, like Facebook or Twitter, or a search engine, like Google or Bing. But according to industry experts, the click referral is becoming an idea of the past, soon to be replaced by content exposure. [...] Most publishers have designed their websites to measure user interaction through clicks, not scroll rates or time spent on stories. As the industry moves away from click-through rates (CTR's) as the most meaningful marketing metric, those publishers will have a difficult time justifying the effectiveness of their platforms for marketers.
