|Readership statistics according to Blogspot|
This surprised me since I hadn't changed my blogging habits in any significant way. Therefore I decided to dig a little deeper. When I started the blog, I enabled Google Analytics tracking because the statistics provided by the Blogspot platform was much more limited. It turns out that the statics provided by each tracking platform were quite different and Google Analyitics doesn't see any similar growth in visitors.
The other thing that has changed is the location that the visitors come from. When I looked at the location of my visitors from 2011 most of my visitors came from Ireland (which is not a surprise) and I had no readers at all from China (I assume that this was because the great firewall of China was blocking access to the Blogger platform). However, I got my first visitor from China in 2012 and they now represent the a very significant proportion of the visitors (according to Blogger statistics, but not according to Google Analytics)
There is definitely something dodgy going on, because I don't think that I am suddenly popular in China. Perhaps this article from the BBC gives some clue.
