Traffic referrers with two websites

[Jbabb]

Hello

Because shopify cannot do checkout in different currencies (unless it is shopify payments and Im not in the US), we have 2 websites, one .com (in usd) and another in .mx (in, well mx)

Both redirect based in geo-location. If you are in mx and type .com it will send you to .mx and viceversa.

My issue here is that I never trust traffic refferals (from shopify or analytics or meta for that matter), as I assume that the vast majority of the .mx visitors come from the .com website since we only advertise that one for simplicity.

Im sure that there are alot of people in my exact same situation, what do you suggest?

Thanks!
