Google announced support of cross-domain rel="canonical" link element to handle duplication across different websites, across different domains. “There’re situations where it’s not easily possible to set up redirects. This could be the case when you need to migrate to a new domain name using a web server that cannot create server-side redirects. In this case, you can use the rel=”canonical” link element to specify the exact URL of the domain preferred for indexing. While the rel=”canonical” link element is seen as a hint and not an absolute directive, we do try to follow it where possible. You could use the tag, to indicate that yourdomain.com/page1.html was the canonical version of yourdomain.com/page2.html, and avoid duplicate content issues by doing so.” Here’re ways of handling cross-domain content duplication: choose your preferred domain; Reduce in-site duplication before starting on cross-site duplicate; Enable crawling and use 301 (permanent) redirects.
