We have one client who has an established eCommerce Site and has created another site which has the exact same content which is about to be launched. We want both sites to be indexed but not be penalised for duplicate content.
The sites have different domains
The sites have the same host
We want the current site to be priority, so the new site would not be ranking higher in SERPs.
Any advice on setting up canonical, author tags, alternate link tag etc
Thanks
Rich
