This article claims that traffic is the most important metric to consider when analyzing your website. Without traffic, you cannot analyze things like conversion, CTR, or any other metric.
While I do agree that traffic is important, I believe this article overemphasizes its importance and is a bit misleading. Obviously any website needs traffic to be successful, but I disagree that it is the main metric you should focus on. Aggregate visits mean nothing – conversions and actions are more important. What good are visits if people aren’t behaving the way you want. It is better to analyze behavior.
