Duplicate content refers to the presence of multiple pages on a website that contain the same or very similar content. Search engines cannot decide which version is most relevant and therefore may ignore all versions, resulting in a drop in rankings. Duplicate content is categorized into the following main types:

1. Internal duplicate content: Multiple URLs within the same site contain the same content.
2. External duplicate content: Similar or identical content between different websites.

3. Dynamic URL parameters: The use of URL parameters may lead to duplicate content, e.g. the same page is accessed via different URLs.
4. Reproduced content: Content copied from other websites is considered duplicate content by search engines.
