Plan: example.com (US shop)
uk.example.com (UK shop)
example.com/blog (blog to promote UK and US shop with back links)
Problem: I want to push the US and the UK shop. So linking back to product and category pages would be good SEO wize.
On the other hand the user experience is bad, because you don't want to be directed to the US shop if you are a reader from the UK and vice versa.
Options: 1) Copy the blog for UK and US users on two different URLs and use hreflang tag (downside: split of backlinks, social shares and content due to comments)
2) Use cookies to redirect user (geolocation) to correct pages. No cookie=googlebot=no redirection. (downside: cloaking and reason for penalty?)
What would you do? More options?
