Seriously? Of course that's what they are doing,it's what they are supposed to do.
The operative word is "trying".
Guessing and failing!
My Adwords spend dropped dramatically when I switched of the Google guessing options like broad match and session based match -- but -- my conversions did not fall. As a result the cost per conversion fell dramatically. If you do Adwords look at your long tail 100% CTR 100% bounce rate search terms and you will see how Google guesses. Its a pile of doo.
Now recently they have done something to change how they are guessing on organic search and it is failing miserably.
