The web is full of duplicate content. Search engines try to index and display the original or "canonical" version. Searchers only want to see one version in results. And site owners worry that if search engines find multiple versions of a page, their link credit will be diluted and they'll lose ranking.

Today, Google, Yahoo and Microsoft (links are to their separate announcements) have united to offer a way to reduce duplicate content clutter and make things easier for everyone. Webmasters rejoice! Worried about duplicate content on your site? Want to know what "canonical" means? Read on for more details.

Multiple URLs, one page

Duplicate content comes in different forms, but a major scenario is multiple URLs that point to the same page. This can come up for lots of reasons. An ecommerce site might allow various sort orders for a page (by lowest price, highest rated...), the marketing department might want tracking codes added to URLs for analytics. You could end up with 100 pages, but 10 URLs for each page. Suddenly search engines have to sort through 1,000 URLs.
