Apologies if this has been asked before. If it has, perhaps somebody could refer me to the correct thread.
From where I sit, Google returns 217 million results for optimization and 31.5 million results for optimisation (with 79.9 million results for SEO).
When optimising/optimizing a website whose business is SEO, which version of the word would we recommend going with, or do we go with both? Simple maths would suggest that you'd stand more of a chance on achieving a higher position on a SERP (on Google at least) with optimisation than with optimization but then you'd presumably be excluding an American audience which, if searching with that keyword, would be spelling it the "ize" way. The same question arises of course with other words which mean exactly the same but are spelt differently on either side of the Atlantic.
Is it generally recognised that SEO stands for Search Engine Optimization rather than Search Engine Optimisation?
I'd be interested in your thoughts.
