15 Best Plagiarism Checker Online for 2020

Looking for best plagiarism checker online in 2020?

In the world of online publishing plagiarism is something that is being done by many writers and bloggers. You should stay away from this particular thing because it is unethical.

What actually the Plagiarism is?

According to plagiarism.org, the following are the forms of Plagiarism:

  • Pretending someone else’s work as your own
  • Copying the full content.
  • Copying ideas and words without giving credit to original author
  • Same sentence with the usage of synonymous without giving credit.

The popular dictionary Merriam Webster defines plagiarism as:

“The act of using another person’s words or ideas without giving credit to that person.”

Basically, copying others’ content is plagiarism.

If you are getting your content written by some writers, you must check the content for plagiarism before publishing on your website because you never know what the writer has done.

He might have given you a stolen copy of the content.  Thus, checking the content is very important because if you publish that content on your blog without checking then not only your credibility will hurt, but Google Panda can also hit your blog.

You must not use plagiarized content on either your blog or anyone else’s. In case if you need to copy a few words or phrase, then don’t forget to give credit to the original author or website.

In this blog post, I am going to list 15 free/paid tools that you can use to check the content for plagiarism. As they are used to check plagiarism, they are called Online Plagiarism Checker Tools.
