I am a noob, so forgive me if I am missing something basic. I just signed up for Google AdWords. I chose only keywords that Google's Keyword Tool said have an Estimated Average CPC of $0.05. After one day, my actual average CPC is over $1.00. What's up with that? I feel like Google raised their price by 20x. Help!
most likely its a QS of your keyword. Improve it. lower QS would result in adwords being hungry to steal your pockets.
