I have encountered the same problem on two different campaigns so I've decided to consult you girls & guys:
I have an adgroup which has only 3 keywords:
[keyword] "keyword" keyword
(same keyword in 3 matches)
Now, I did a search today for a competing product, and my ad has came up. My search was for *only* the name of my competitor product, and I can't see why is my ad shown. This happened also in another campaign.
I now think that I have been paying for untargeted traffic for a while without knowing..

did you see your ad listing on Google.com or one of the search partners. If you use a broad match and promote via the search partner network, then your ads are subject to Google's "expanded broad matching" feature which allows Google to display your ad listing whenever Google thinks that the user search is remotely relevent to your keyword listing.
So if you bid on the word "puff daddy ring tone" and the user types in "my dog has ring worm", then Google may decide to show your ad on a search partner site. Why? Google wants your money. They typically do this when your keyword CPC bid is higher than the norm.
