I googled around this for some time now and the answer is not completely clear for me. I found a similar question here Is defining an hreflang sufficient to avoid duplicate content penalties between US and UK sites with nearly identical content? but this was regarding a web-shop, which was exactly why it was easier to do.
The website I'm working on is not a web-shop. The us site will be on a subdomain: us.example.com
I wonder weather there is a way to make sure that google will not consider uk and us sites as duplicate? As the content on both sites will of course be quite similar. I do know about hreflang, but are there other things to be done to make it easier for google? Or do you have some good tips for this issue?
