Also, we have to keep in mind always to make our content an excellent no-copy material. Here the term comes “Plagiarism.”

What is Plagiarism all around?

Plagiarism is an act of duplicating the content or ideas or expressions of others and publishing it as your own. It is nowhere appreciable. Instead, penalize.

It is immaterial; you may be a blogger, a freelance writer, or academic teacher or even a student.

Types of Plagiarism

For your update, there are two varieties of plagiarism.

I am aware that scenarios like you may not doing it intentionally. If someone’s writing styles exactly match yours, then the chances of duplication will be high. This way of duplicating falls under unintentional plagiarism.

However, check your content at least to know yourself that the content is fresh and unique. Before publishing, you can prove that you are genuine.

Still, there are enough people may be students or freelance writers, article spinners trying to steal or misuse someone else’s ideas or content to save time. Thus, completing their task with fewer efforts. This tactic of copying and misusing refers to intentional plagiarism.

Moreover, they may think that this will not be affecting them in any way. But it’s wrong. You will have to verify the content for originality using efficient best free online plagiarism checker tools or plagiarism detection tool and make your content free from copy or duplication.

Myths Behind Content Duplication

There are misconceptions that the domain that has duplicate content is subjected to Google penalty. Even, reading this line, you will be murmuring ‘yes, of course’. Perhaps, content duplication might impact your ranking, but Google has no such ‘content duplication penalty’.

Google never hunt for duplicate content and penalize. On behalf of online users, Google just needs content diversity to serve them. Not, the similar content or ideas over and over.

The search engine algorithms are built in a way to group different versions of content to form a cluster. Considering other few factors like the links from the page, originality, domain age, authority, etc. search engines consolidate the ‘BEST’ and rank that one.

Hope, you are now clear about ‘how Google or any other search engine handles duplicate content’?

Then, Why Demanding Plagiarism Check?

Then, why it is imperative to check for content plagiarism? Why should I invest my money in plagiarism checker tools?

Google has no such penalties for plagiarism though. Still, if content plagiarism can spoil your credibility among users and impact SE ranking, then what’s the need to do so?

Moreover, there is certain other regulations act that has rights to warn and penalize such fraudulent activities. If somebody duplicates your copyrighted content, then you deserve all the rights to file a request (under DMCA) to remove duplicate content.

So, if you are likely to withstand in the market with credibility and better search engine visibility, then your content must be unique.

Also, there are chances to produce duplicate content not even knowing that it is a plague (unintentional plagiarism).

In such cases, you must rely on these smart duplicate checkers. You can also keep yourself out of trouble from the webmasters. Make sure your content is original before publishing it online.

How to Check Plagiarism?

I could see more queries raised in forums and other discussion platforms by Professors and researchers about ‘how to check plagiarism?’

One of the significant problems they face is checking the content duplication in scientific documents, student’s academic essays, etc.

Whenever they get a document submission from their team or students or junior professional, they are worried about its originality.

To overcome all these, how do they check Plagiarism? Which is the best way to check content duplication?

How reliable are these best free online plagiarism checker tools?

By the way, manually verifying the documents is nearly impossible. How to check the Plagiarism in the research papers, Ph.D. thesis, journals, etc.?

Obviously, you have to rely on such a reliable plagiarism checker software programs.

    Thanks to mentioned these powerful plagiarism tools.

    1. Sumit,

      Why not, you may use multiple plagiarism checker tools to check same content to be unique. Still, if you are using a highly reliable tool, then why to invest in multiple tools. Grammarly compares your piece of content with billions of web pages and comes out with the percentage of content duplication. It also highlights the URL where the content is copied. You can easily spot it, request webmaster to remove the duplicate content if yours is original. Otherwise, you rewrite your content to be unique.

  7. Hey there Sathish,

    I never knew that a lot of proofreading tools are out there.

    I used to use Copyscape mostly when I publish article on my niche sites, and I always have Grammarly on my browser (it really helps a lot, especially when we are in a hurry)



    1. Melos,

      Yes, there are a plethora of English proofreading tools available. I have shred very few but curated list of plagiarism checkers here. And yes, Grammarly comes for free to help any writers write anywhere online. If you have got a chance, give a try to its premium version. You would love to use it forever.

  8. Hi Sathish!

    Thanks ever so much for your list of tools for helping to combat plagiarism. 🙂 I’ve been using Grammarly (the free version) for a while and had no idea it monitored duplicate content. So I’ll definitely have to upgrade.

    Over the last few weeks or so, just on the off-chance, I’ve caught out 5 websites that had duplicated a large chunk of one of my reviews. But luckily, I got Google to remove all 5 reviews.

    It just so turns out that someone on Fiverr had created the content-thin sites with the use of Black Hat link building strategies. All 5 reviews had actually outranked my original review lol.

    All Fiverr offered to do about it was “monitor” the seller who is no doubt still up to his/her old tricks.

    I have no idea if the person has other duplicate content from my site, but using a tool will definitely help.

    The annoying part is having to report the sites to various platforms like Google, Fiverr, domain registrars and also hosting companies for abuse. It’s so time-consuming, and valuable time taken away from my Biz.

    The thing I want to know is why Google allows these duplicate content-filled sites with shady link building tactics to rank on page 1 for so long? I thought Google is meant to take swift action against those individuals?


  9. I stand with you Neil. Those webmasters who are attempting content duplication must face the consequences. They might rank well but that would not be retaining for ling time. Google is more serious about identifying the plagiarism and taking actions. You may use tools like Grammarly, CopyScape to make sure your content is not stolen by anybody.

  10. A specialized paper requires plenty of skills and knowledge. And if you are not interested in writing it by yourself, then you will really get bored and irritated by such a difficult task. Therefore, in order to evade pressure and wastage of time, you can take help from one of most skilled dissertation writers.

    I have taken the services of assignment friend and must say they provide high-quality writing service, particularly in the area of the dissertation, and deliver professional assistance the students whenever they needed. They have employed the best dissertation writers who have acquired positive feedback from the clients.
