Hi, I am trying to target high-paying keywords but not quite sure about how it works. E.g. if 'free car contest' has a high minimum bid how many times would I have to use the word 'car' in my article for these keywords to come through? 1? 10? 50? 0.1% of words? 1%? 10%? Or would I need to use the entire phrase 'as is'? or would mixed up (e.g. car contest for free etc.) work? Any help greatly appreciated. Thanks
