> duplicate content On the same website or across the web (or a network) ? edit: ah, from the page you linked > Every page should provide unique content that doesn’t appear elsewhere on the site. Search engines will penalise or even completely hide pages that are too similar as showing duplicate search results is unhelpful to users. Duplicate pages can also reduce the search rank benefit of backlinks because it’s better to have backlinks to a single URL compared to backlinks spread over a set of duplicate page URLs. Crawling duplicates will also use up the resources search crawlers allocate to crawling your site which means important pages might not be indexed. You can eliminate sets of duplicate pages by consolidating them to a single URL using redirects or canonical tags. |

> Duplicate content generally refers to substantive blocks of content within or across domains that either completely match other content or are appreciably similar. Mostly, this is not deceptive in origin. ...
> Google tries hard to index and show pages with distinct information. This filtering means, for instance, that if your site has a "regular" and "printer" version of each article, and neither of these is blocked with a noindex meta tag, we'll choose one of them to list.
> In the rare cases in which Google perceives that duplicate content may be shown with intent to manipulate our rankings and deceive our users, we'll also make appropriate adjustments in the indexing and ranking of the sites involved.
