OK, of course referrers is undercounted. I've run enough of my own web servers, over the past fifteen years, to know that's impossible to avoid, whether you use javascript or the actual web server requests.
But the undercount I'm seeing here is absolutely ridiculous, and bizarrely inconsistent.
I can have my activity, for a specific article, increase by a factor of ten, because a specific high-volume website linked to me:
The total hits then skyrockets. This comes with a boost in the referrers from that website...but sometimes only a fraction of the overall increase in that page's loads.
As a parallel problem, I am puzzled by the times that the grand total of all specific page loads listed for a day, if you add them yourself, is a fraction of the number of views for the whole site in the chart. Now I know those can be inconsistent, but sometimes it's a huge multiple, other times it's only a percentage.
The blog I need help with is butnowyouknow.wordpress.com.
