Duplicate content refers to content that appears on the internet in more than one place, either on the same website or across different websites. This can include entire pages or parts of pages, such as paragraphs or images, that are copied from another source.
Search engines generally avoid ranking duplicate content highly, as it can confuse them about which version of the content to index and display in search results. This can lead to lower rankings for the pages involved. To avoid issues with duplicate content, it’s important to create original content and, if necessary, use tools like canonical tags to tell search engines which version of a page should be considered the primary one.
