Welcome to the Q&A Forum

Thanks for your comments Dana! I do appreciate the time you took to help explain more about hreflang.

I have implemented hreflang on multiple other websites in different languages without any issues. However, this situation is a bit different. To answer your questions...yes, our main site is the English site in the US & Canada. Same exact site, URL, content. We want every other visitor in the world to visit our international subdomain.

If implemented the code below, what would happen if I searched our website brand in the US? Would our main site come up? What would happen to a searcher in France? Would Google serve our international site?

By your comments above are you suggesting the below?

I wasn't suggesting to include both on the same page. Thanks!

You should have rel=canonical tags on your SEO state pages and noindex your PPC state landing pages.

My company is creating an international version of our site at international.example.com. We are located in the US with our main site at www.example.com targeting US & Canada but offering slightly different products elsewhere internationally. Ideally, we would have hreflang tags for different versions in different languages, however, it's going to be an almost duplicate site besides a few different SKUs. All language and content on the site is going to be in English. Again, the only content changing is slightly different SKUs, they are almost identical sites. The subdomain is our only option right now. Should we implement hreflang tags even if both languages are English and only some of the content is different? Or will having just canonicals be fine? How should we handle this?

Would it make sense to use hreflang this way and include it on both versions? I believe this would be signaling for US & Canda visitors to visit our main site and all other users go to the international site. Am I thinking this correctly or should we be doing this a different way?
