I thought I was going mad for a while – in fact I haven’t ruled it out.
When pulling segmentation data through the Google Analytics API for April 2011, I was getting 0 every time. After several head-scratching hours I could find nothing wrong with my software, so I ran a report on the web and got the same result.
It seems that source segmentation is unavailable for April 2011. I’ve tried across several accounts, UK and US, large and small.
Most other segments seem to work ok.
What’s surprising is that I can find no mention of this anywhere.
