Whether to use British English or American English - does it matter from SEO perspective?

If you are marketing in english speaking countries, I don't think it matters as long it is a common word such a color or colour. I would use American English when different terms are used such as zed and zero, stop and period, trunk and boot, etc.

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.
