I'm ramping up on my SEO, and I've just begun using keyword utilities. One of the ones I'm using differentiates between "Keyword", "keyword" and "KEYWORD". I've always thought that the search engines would consider all three the same. Does this mean that if I want to come up for "keyword" that I also need to target "Keyword" and "KEYWORD"?

Thanks,
Chris
