What is plagiarism?

Simply put, plagiarism is a form of cheating. It refers to the act of copying someone else’s content and presenting it as your own . Taking someone else’s photo and using it without permission and/or proper credits can be considered plagiarism. Similarly, taking text from a source and using it on your website without proper citation is also an act of plagiarism.

In academia, getting caught plagiarizing can result in expulsion and permanently jeopardize your future plans. Stealing content for your own blog is also not considered flattery, and it is not legal. Copying content for your own website can get you reported and result in your site being shut down.

The most common types of plagiarism

  1. Verbatim plagiarism – This is a common offense of copying text or content exactly as it is written, without any form of credit or citation.
  2. Mosaic plagiarism – This type of plagiarism involves copying content from different websites or sources and combining them without any form of credit or citation.
  3. Global plagiarism – This means deliberately claiming someone else’s entire work as your own.
  4. Self-plagiarism – This occurs when you resubmit your own work after you have already used it. It is also called self-plagiarism.
  5. Accidental plagiarism – This occurs when you unintentionally commit plagiarism by rewording content and failing to cite or add credits.

Content is an essential ingredient in SEO ranking, which is always a fierce competition. Websites are usually looking to produce more content than they expected. A group of writers usually solves the problem, but that’s also where a new problem arises: monitoring the content.
