They detect copied content (plagiarised content) very fast. So you have to take care of your content not to get copied by others. Are you searching for free plagiarism checker tools? Let us know what the best plagiarism checker is?

What is Plagiarism?

Plagiarism is an act of Fraud. It includes taking or stealing others’ work, a person’s writing, conversation, song, or even idea and passing it off as your own. Just it is a part of cheating or similar imitation of previously published articles of another author’s content online without their permission.

How to check for Plagiarism?

I recommend that every blogger or existing blogger create a copyright page and keep the link at the footer side or any other visible places.

Create a new account on the DMCA (Digital Millennium Copyright Act) new account. Place the code on your blog. It starts working by scanning your pages and checking online about copy scrapers.

As a blogger, I am writing content regularly for my blogs by spending more time and Publishing 3 to 5 articles every week.

I know the pain of content theft. At the time of the beginning, RSS scrapers were stealing my content. I improved my WordPress security levels.

What is a Plagiarism Checker?

A plagiarism checker is a tool that helps us in checking the plagiarized content. By using the plagiarism checkers, you can check any document or some words of content to know whether it has been plagiarised by any chance. 

Once you paste your content in the plagiarism checker tool and hit enter, the tool will start searching all over the internet for the content, whether the same content is used elsewhere. While most of the tools check for similar content, some sensitive tools give out similar wordings too.

Once they searched the whole article, they will show all the plagiarised lines along with the sources. 

It is also an important thing to checking for plagiarism before publishing your newly written content. The chances are that any article written over 100 words may be plagiarised. Hence it is always good to hit the check plagiarism button before publishing. If you get non-unique sentences, you can quote them or rewrite them in your own words

What does a checker do?

Generally, a plagiarism checker searches all over the web for content that is similar to the content you put in the checker box. If it finds any content on the web which has similar wordings as in your content, then the checker concludes that the content in both cases is the same and displays it to you along with the link to the article. 

It searches individual sentences and phrases and checks for similarities. After checking all the sentences in the content, it will give the overall score of the plagiarised content.  

Benefits of using a plagiarism checker

While not having plagiarized content is crucial, there are some benefits of using plagiarism checkers other than manually checking over the web. 

  • You will get links to pages from which your content looks similar. 
  • You will get the overall percentage of the plagiarized content
  • Within no time, all the sentences will be plagiarism checked 
  • It helps you improve your paraphrasing or otherwise called content rewriting skills, which help complete your articles without any plagiarism.

    These tools are very good. I used ‘Grammarly’ for a long time, but unfortunately, I can admit that it’s good for checking grammar but not for plagiarism. I’ve tried a lot of good plagiarism checkers and some of them are really very nice and not so expensive.
