If I have a 3 word keyword, does it work for just that sequence, or a combination of the words?

Yes you will show for various combinations and you can even show for abbreviations. You arre much more likely to rank higher for an exact match keyword though, so if someone types in siritual groth tools and thats your exact keyword you will rank higher than if somone types in another combination.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
