But, the software of the website only enables the same article that you have to retrieve via multiple URLs. In the developers’ eyes, the unique identifier is the ID that the article holds in the database and not the URL. But for Google, or any other search engine for that matter, the URL is the identifier for the content.

For this activity, you must give them a Session which is a brief history of the visitor’s activities on your website. To monitor that session, as soon as a user navigates from one page to another, you must store the Session ID somewhere else. And the most commonplace solution to do it is with the assistance of cookies. Also, you must note that search engines do not generally hold cookies. Now, at this point, some systems revert to operating Session IDs in the URL. This indicates that each and every link that is internal on the site, receives the Session ID which is added to the URL. And since the Session ID is unique, it forms a new URL thereby duplicating content.

At most times, the cause and reason for duplicate contents are probable human-made mistakes and errors. However, other websites seize and use your content, sometimes without your consent. Or sometimes, with your consent as well. However, they don’t regularly link to your authentic article and hence, the search engine fails to retrieve it. Therefore, it has to bring up another version of the original article. Note that your website’s popularity is directly proportional to the scrapers you receive.
