Plagiarism has been a pain in the ass for many content marketers, and if proper care is not taken to prevent publishing copied content on your prestigious blog, then, I’m afraid, you won’t be on this for long.
The painful truth is that people are lazy these days. Just ask most people who claim to be freelance writers to write a short 500-word article on any topic, and they will copy it from the internet and present it to you. Now, as someone busy with so many other things, you might end up publishing such stolen pieces on your blog, and what do you think might happen next?
Oh yeah, you guessed it right!
You will start getting embarrassing emails from the original owner of the article asking you to take it down, or, I guess, you already know.
However, the problem of plagiarism does not only surface when you outsource articles. Suppose you’re someone who accepts guest posts from other bloggers. In that case, chances are, some of the guest posts you often receive might not be original as well, and having such articles on your site will only be sabotaging your SEO efforts, thereby putting your blog on the line.

A survey carried out by the Psychological Record shows that 36% of undergraduates have admitted to plagiarizing written material.
Similar to publishing copied content on your blog, someone might also copy your own articles and publish them on their blog, and as you already know, this can result in Google penalizing your site. It is therefore essential to monitor your articles regularly to ensure no one copies you without proper permission and attribution.
Luckily, there is a good solution to this: always use plagiarism-checking websites to determine whether you’re dealing with original content. There are many such tools on the internet today, but many people can’t afford them, which is why I’m writing this post for you.
Are you searching for free plagiarism-detecting tools? Do you really desire to ensure every article that goes to your site is pure, immaculate and original?
Well, if you answered yes to the questions above, then search no further, you’re already in the right place.

What is Plagiarism?
Now, if you’ve been in the content marketing business for long, I bet you already know what plagiarism stands for. But in case you don’t, I will take a little time to explain.
Plagiarism is copying from other sources without giving credit. It’s like cheating and taking someone else’s hard work to claim it as your own. Due to the immense growth in website creation, more and more people are searching for easy ways to copy others’ content to get more traffic to their websites.
Though Google search engine crawlers are smart enough to know which is copied and which is not, but you have to take care of your content not to get copied by others.
As a blogger who works online most of the time, it isn’t unusual to stumble upon my work published on websites where I never gave permission to reproduce it. After all the painstaking effort put in, especially in writing my web hosting review articles, it is annoying and frustrating to find my work being irresponsibly copied by other “writers” on other web hosting blogs.
Plagiarism can simply be defined as the most “similar imitation” in which a particular work previously and originally done by an author is copied without the author’s knowledge or approval.
Plagiarism can simply be defined as the most “similar imitation” in which a particular work previously and originally done by an author is copied without the author’s knowledge or approval.
I recommend everyone who blogs to create a copyright page and place it on either the footer or the most visible places on their websites. This way if someone copies your content, you can ask DMCA or Google to remove that content from your websites, you can even take copyright infringement issues against them. Start immediately creating a copyright page for your blogs and websites.
Types of Plagiarism
It might interest you to know that plagiarism comes in two forms, namely: Intentional and unintentional plagiarism.
- Intentional Plagiarism: This is a case where someone intentionally copied your content; in other words, he did it consciously. This is what most cheap freelance writers often do. Article spinners and newbie bloggers who know nothing about the various laws guiding the internet are also victims of this.
- Unintentional Plagiarism: In this type, the copied content is done without you being aware of it. This can usually happen when you’re writing and there happen to be traces of some sentences similar to what you have on your content. Also, it can be detected when you quote someone else work without giving proper attribution and credit.
In either case, you’ve committed plagiarism and will face the consequences if nothing is done about it.

Why Use Plagiarism Detecting Tools?
To simply detect the copied content online. If you want to know who copied your content, plagiarism detectors help you easily figure that out. Google releases the latest updates to either penalize or reward websites.
If your websites have thin content or use bad strategies to build links, they will automatically get penalized by Google’s updates like Panda and Penguin. If you have quality content, you will get top results in SERP’s, it is as simple as that.
So if someone copies your content, Google crawlers see multiple pages on their search results with the same information. Even if you are not copying from others, your site might be penalized because others are stealing from you.
To prevent this, you need to regularly check Google search results to see whether anyone is copying your content. Then you need to take specific actions (DMCA, etc.) to remove that content from other pages.
To find who is copying your content on the Internet, plagiarism-detecting websites help you solve your problems. Yes, you can also use Google (by copying and pasting your own content) to find who is copying your content, but it becomes a mess when you want to search for bulk web pages.
That’s why I decided to write a specific post about using free duplicate content checker tools to find copied content. I hope you will like all of them. Try one after the other, and let me know which one you liked most in the comment section.
