Duplicate content

Text that appears on the Internet in more than one place (URL).


Duplicate content refers to substantive blocks of content within or across domains that either completely match other content or are appreciably similar. Typically, it’s not deceptive in origin. Search engines like Google strive to provide users with diverse content options, hence, they might filter out duplicate content, affecting the visibility of such content in search results.

Usage and Context

Duplicate content can occur on different pages of the same website (internal duplicate content) or on different domains (external duplicate content). Causes include printer-friendly versions of pages, identical product pages on e-commerce sites, and content replication across domains.

Although not inherently manipulative, excessive duplication can impair user experience and dilute link equity, potentially harming a site's SEO performance. Understanding and managing duplicate content is essential for website owners and content creators to ensure their content is effectively indexed and ranked by search engines.
