    It's interesting to read, but what exactly are the data correlated *with*? Seems to be some measure of SEO, but I'd like to see the exact metric that's being used mentioned in the charts that display the correlation. All in all, very interesting!

    Hi James Sorry for not being more clear, the data is correlated against rankings i.e. how well are exact match domains correlated to ranking well in Google? The way the formula works is you feed in two sets of rankings, one set is obviously the set of rankings in Google e.g. #1,#2,#3,#4, etc. and the second set is the factor you are testing so for exact match domains 1 would represent if it was an exact match domain and 0 if it wasn't.
