Google Now Tells You Impressions & CTR For Organic SERPS
I don't look at it very often, so I don't know how long this has been the case (it wasn't the last time I looked) but, if you use Google's Webmaster Tools, have a look at the "Top search queries" section.
It was always the case that this told you which search terms you are ranking for (and where in the SERPS) but, now, it also tells you the number of impressions, the number of clickthroughs, and the CTR %.
From what I can tell, it also shows what the impressions, clickthroughs, and CTR were when you site was at other positions prior to where it is now.
Fantastic!
