Here's the scenario... Client has two domain names:
Both have identical products, but different currencies (AU$ and US$).
The problem (as most of you will know) is that without using a sub-domain or country-code top-level domains, Google has no idea which domain should be served for which domain. Furthermore, because the root domain is different, Google doesn't see any connection between the two - other than the fact they have identical products!
My recommendation to the client is to change to:
Arguably, we could leave the second one alone. But I think it's better for the brand to use the same root domain for each.
Obviously this means both will need to be redirected. Since NONE of the pages within the sites will change, do we need to redirect every page, or just the root domain?
Any other risks or concerns we should know about?
