I'm in the same 'boat'. Almost all my traffic is from Google searches (I don't do AdWords or advertising like that). I don't worry about Yahoo or MSN, though. I look at long term growth in traffic/referrals from all sources. And when I say long term, I have data going back to about 2001. Some months are up, some months are down, but the trend every year of total traffic has been, and continues to be, up.
