The term duplicate content can be found especially in SEO search. It refers to identical content that can be found on two or more websites at the same time. Duplicate content can take a variety of forms, such as directly stolen content that has been taken from other sites without permission, or content that has been shared with the author’s permission, but this must be set up in a way that is obvious to SEO search engines. The problem that arises between duplicates can also be the same or similar URLs.
