Do You Have Duplicate Content Issues Across Domain? Google Will Now Alert You

Today, Google webmaster tools has launched a new message alert to let site owners know when a particular URL doesnâ??t appear because Google sees it as duplicate of a URL on a different domain. In the blog post announcing the feature and in an in-depth help topic, they provide details on how they identify duplicate clusters of content and choose a â??canonicalâ? version of that cluster to display in search results.
â??When we discover a group of pages with duplicate content, Google uses algorithms to select one representative URL for that content. A group of pages may contain URLs from the same site or from different sites.â?
They note that when they choose a representative URL from a different domain, they call this â??cross-domain URL selectionâ?.
