Jeffrey Cammack asked Google’s John Mueller if it matters if someone uses American English versus Australian English. John Mueller said “it doesn’t play any role for SEO” and added it might impact users “but not directly for SEO.”

Here are the messages on Twitter:

I’d think that Google would be able to pick up on the differences in the English and just like they process different languages to rank better for different localized versions of Google, they might do the same here? So a web site written in Australian English would rank different in Google Australia than it would in Google USA?

I guess I am wrong?

This is all without implementing href lang and Google Search Console’s country selector.
