Duplicate content refers to substantial blocks of content within or across domains that either completely match other content or are appreciably similar. Essentially, it’s when the same or very similar content appears in more than one place on the internet. This can happen for a variety of reasons, such as when website content is copied and pasted from one page to another either within the same site or across different sites, or when product descriptions are distributed across multiple e-commerce platforms. Search engines like Google try to provide the best user experience by presenting unique content in their search results. Therefore, when duplicate content is present, it can cause problems by making it difficult for search engines to decide which version of the content is more relevant to a given search query. This can result in the dilution of ranking signals, which may affect the visibility of the content in search results. Moreover, it can lead to a poor user experience if people encounter the same content repeatedly. To address duplicate content issues, website owners and content creators can use methods such as setting up 301 redirects, using the canonical link element, or improving content uniqueness across their web properties.
