For some time now I have been chasing a paricular keyphrase, and have been interested/annoyed/confused that if I turn it backwards I get listed well. Unfortunately people don't often put the keywords in the wrong order :)
Using thumbshots clever tool, here are a few examples (NOT the keywords I am chasing, just examples):

Or just check your rankings using your favorite tool with your keywords in a different order ... you may rank quite well ... for unlikely searches !
So, does this mean that we should put more emphasis (somehow) on the first word in any keyphrase? Mention it a little more often on our pages and IBLs? Or just hope people like putting words in the order wrong ...
