External duplicate content refers to the presence of the same content on multiple web pages belonging to different websites. This phenomenon can affect an entire page or only a portion, such as a passage or paragraph. It can result from authorized content reuse, illegal copying of content, or distributors using the same information found on product pages often provided by the manufacturer.
Detecting duplicate content is crucial because when Google identifies this situation, it adjusts its search results to avoid displaying multiple pages with identical content. In cases of content duplication and filtering by Google, only the page considered the original or most reliable will be displayed in the results.
Cases of external duplicate content can be managed more easily from a technical standpoint when it involves authorized reuse and the website in question cooperates. However, management becomes more complex when content is reused without authorization, despite Google’s progress in this area.
