plagiarism checkerPlagiarism Checker Tools are important tools for students and teachers, as well as for online bloggers, writers, and SEO agents. This is important in the sense that it allows authors to check their contents/materials for originality, and at the same time, allow them to check if any of their content/material has been stolen.

But before anything else, let us discuss what is Plagiarism?

Plagiarism (sometimes referred to as copypasta) is an act of stealing and passing off the ideas or words of another as one’s own. It is an act of presenting a content, product, or idea as new and original without giving any credit to the source. In other words, plagiarism is an act of fraud and literary thievery.

In the U.S. and other countries, the expression of original ideas is considered intellectual property and is protected by copyright laws. This includes all forms of expressions as long as they are recorded in some way (ie. book, computer file, or a published online article).

A Plagiarism Checker tool works for the purpose of detecting plagiarism. It allows users to check the web for duplicated contents. If you are an author, this ensures that your work is original. It also allows you to see if someone has been using your work without your consent. If you are a site owner or Blogger, a Plagiarism Checker can also be most helpful since it does not only ensure that your content is original and let’s you avoid legal issues in the future, but also because it could help you with the SEO (Search Engine Optimization). Some Search Engines, like Google, are checking the web for plagiarism and penalizes a website that does that. With the checker, site owners and bloggers can avoid that problem.
