The Google Webmaster Blog has posted some useful information on ways to manage the issue of duplicate content, which is becoming a common issue for many sites. This may be caused due to the difficulties of managing large dynamic sites, or very often due to syndicated content being shared between sites. The other main example used by Google relates to content which may be duplicated due to 'screen scraping' by third-party websites that are creating mass content from original sources, which can occur for various reasons.

The Google article provides links to previously published advice and tips on how to handle such situations. It also provides guidelines on ways to ensure that original content can be indexed by Google, which should be the main concern for the content creator.
