A little question about stop word and KW density

Hello I would like to know the following:
Let's say I want to rank the following keyword: Best products New York
If in my article I use the following variation:
Best product in New York
Best product [New York]

Will these count as the target KW I'm trying to rank or do they count as a different KW? If I use a stop word inside the KW Im trying to rank will be bad for my KW desnity?

Are you asking us if you should put the [ character around a keyword as if you were posting a broken spin?
