It takes a random passage from the website copy and verifies whether it already contains the web content of that page or similar text. To this end, the Google Index is used. The duplicate content reviewer will indicate this if websites with the same or similar content are found.

The URL where the duplicate content is discovered, as well as the sections that may be duplicated, are saved. In most cases, the web pages will be compared word for word. Users can select how sensitive the duplicate content checker should be in various software packages, such as whether duplication is regarded to be as little as four consecutive, identical words or only after nine or ten.
