Sitecore comes with a sophisticated set of analytics tools that uses not only for tracking site visits, bust most importantly for personalization and other marketing functionality. But what to do if the analytics does not work? Where is the problem?
The solution of the problem however might be fairly simple. Every Sitecore layout (i.e. ASPX) must contain the tag <sc:VisitorIdentification runat="server" /> . This tag allows Sitecore to recognize a human user from a robot (by generating a CSS script). If the tag is missing, the results in analytics might be either compromised or miss altogether.
