Is this a good strategy....I have a number of very closely related keywords that all get good enough traffic to try to rank for...so my thought is to try to optimize one post that has all the keywords in the one post as they are so closely related. So I think if I repeat each keyword 3 times that is good enough. Is this a good idea, is there such a thing as trying to rank 1 page for to many keywords? Is repeating the keyword 3x enough or even less ok??
