Top 15 Online Plagiarism Checker Tools for Bloggers in 2019

Sharing is caring!

Writing is like

breathing for bloggers. If you want to grow your blog, one way to do it is to

increase your publishing frequency.

But what may break you is that you write great content and then find out that Google penalizes you, why that?

Because there was plagiarism in your articles. And all your hard work is gone because one article was a little bit similar to another’s. Annoying, right?

What is even more annoying is that you start hiring people because you want to grow your blog even more and start focusing on more important strategies.

In the end, you find that your blog is penalized and instead of growing your traffic, your traffic will drop dramatically in a day without any notice… and you lost the money you paid for the writer.

What if you could know if there are any similarities between your post and others on the internet with a quick check before publishing your post, so you don’t get penalized and all your hard work is gone without you notice.

That is what you are going to discover in this post.

But first, let’s discuss plagiarism, later we will discuss online plagiarism checker.

What is plagiarism

To put it in simple

words, plagiarism is stealing someone’s idea or work without referencing him.

So if you are writing an essay for your teacher and you are going to write about an idea that is already covered by someone’s else, you need to reference him at the end of the article.

If you don’t, then you have already done plagiarism.

When thinking about it, then most of the content you write isn’t your ideas. But copying the same content, even if you change the wording a little bit is considered stealing and plagiarism.

And what is worse is that you copy parts of different articles and think that by that way you have a unique article, and actually you don’t.

And this won’t do

you any good, so don’t try to do it if you are serious about blogging.

Types of Plagiarism

There are different

types of plagiarism, but here are the few that are common.

  1. Direct Plagiarism: This is plagiarism in its best shape. You are just copying a post or an article word by word and call it yours. If this is your strategy. Stop blogging right now because you are wasting your time and money

  2. Mosaic Plagiarism: This happens when you copy phrases from a source, but don’t put it in quotation marks

  3. Self Plagiarism: It occurs when you publish your work multiple times. This could be a problem if you don’t optimize your other posts right so Google doesn’t penalize you.

  4. Accidental Plagiarism: It occurs when you accidentally write a phrase or a sentence and someone has already written it the same way. This happens for the best of us, and this is what we are going to try to solve in this post.

How Google takes action against plagiarism

Google hates plagiarism. The least thing they want is to show their searchers content that is similar to each other, which provides a terrible user experience, and this will decrease the earnings of Google.

This is a simple

reason why Google hates plagiarism. In the end, it is going to affect their


So what they do?

Once they notice that any of your articles has parts of it copied from other

sources, they penalize your blog and make it unworthy of their trust, so your

hard-earned rankings for the other posts are affected as well.

And it happens in a


After that, you need to start diagnosing the problem to find why that happened, solve it, and then start trying to get them to rank you back. That would take months if they do get you back.

Sometimes, they won’t even take you out of it, so you are penalized for life.

Hard, right?

The solution could

be simpler. Just do a quick check for plagiarism before you publish the post

and you are good to go.

So which tool to use

to help you check for plagiarism before publishing your post without taking

much work from you?

The last thing you

want is a tool that is going to waste your time and not help you find if your

post is plagiarized or not.

Best Tools to Check For Plagiarism

To help you solve

this problem and not worry about plagiarism once and for all, this post was

created to share with you the top tools that check for plagiarism without much

work from you.

So you don’t need to worry if any of your articles accidentally contain similar phrases to others, or if any of your writers are copying content from other blogs without you knowing.

Of course, you won’t know all the content on other blogs writing about the same articles, and you don’t need to check them all every time your writer send you a new article. That is harder than writing the content yourself, right?

So without further ado, here are the top online plagiarism checkers…

1. Grammarly

online plagiarism checker

Grammarly is one of the first highly-sophisticated free online plagiarism checkers for students and editing tools that use its AI to understand what you are writing and offer you advice on how to improve your writing. It is not just a grammar and spelling editor.

And they can’t call

their tools one of the best if they can’t check for plagiarism. And that is why

they have their plagiarism checker.

Their checker catch

plagiarism from the ProQuest databases and over 16 billion web pages… yes,

you read that right.

So it is not only

created for academic purposes, but also for writers who don’t care about a

degree from their teacher and just want unique content that pleases Google.

And of course, you

won’t need to worry about your writing going public before you publish it, so

don’t worry about that.

And here is the thing, you could use their plagiarism tool for free, by going to this link.

And if you have the pro version, which I recommend you to do, then they will check it for you automatically, while you are editing your post, so you don’t need to do a separate check.

If you are wondering how I write good content without much errors in English and English is my second language, then I am sure you already know my secret 🙂

2. Copyscape

Copyscape is one of

the first popular plagiarism checkers created.  It is created to solve 2

problems as a blog owner.

  1. Find if your content is original or not. You don’t want to get laughed on by a writer who pays your hard earned money to just copy content from other sources. Their tools help you solve this problem

  2. Know if someone steals your content: it is easy for someone to steal your content and there is nothing to do about it if you don’t know that they exist. Their Copysentry program scans the web daily for copies of your content and emails you when someone copies your content, how cool is that?

There is a free version that lets you check your post after its published. Just enter the URL of the post, and leave them to do the rest.

If you want to copy and paste your content and benefit from their other tool that checks your content, copy sentry, then you need to get the premium version.

One cool feature is

that you could also check your entire site for plagiarism, how cool is that?

The price of the premium version is 3 cent per search (for up to 200 words.) Every extra 100 words will cost you 1 cent.

Not a bad investment for your site.

But if you are planning on benefiting from the editing capabilities in Grammarly, then spend your money there and don’t bother with extra tools, unless you are hit by Google and want to check your whole site for plagiarism.

You can do so here, without taking much time copying and pasting each of your articles, especially, when you have a long list of words.

3. Plag Scan

Plag Scan is another

tool that helps you find the “authenticity” of the word written as

they say. They check your content for any similarities with other content

on the web.

There are many

different plans that were created for education and big business purposes that

we won’t bother with.

Their private

plan is what may be of interest to you.

This tool is not for

free, but you could get a free trial to check the tool. Their payment is a

pre-paid system, where you pay depending on the number of words you want to

edit. They don’t care how many documents you scan, they only care about the

number of words.

The smallest plan

where you can check 6500 words for 5.99$. 25k words for 12.99. 62.5k words for

24.99$. 150k words for 49.99$.

As you can see, the

more you pay for, the cheaper it comes. In the beginning, you were paying

1$/1000 words. In the biggest package, you are paying 0.33$/1000 words. So keep

this in mind, if you plan to use this tool.

4. ProWritingAid

best online plagiarism checker

Pro Writing aid is another tool that is created to help writers make their content look like a professional writer has written them without being a professional yourself.

It helps you with editing style and grammar mistakes and helps you find the right words to use.

Again, like Grammarly,

they need a plagiarism tool to make their tool more complete and they did just

that. But there is no free version like Grammarly.

You need to either

have the premium version or purchase plagiarism check packages.

You get 50

plagiarism checks a year in any of their premium versions, where you pay for a

year or more in advance. There is also a lifetime option.

You could buy

plagiarism check packages depending on the number of checks you want to do. For

10 checks, you pay 10$. For 100, you pay 40$. For 500, you pay 120$. For 1000,

you pay 200$.

Again, as you see,

the more you pay for, the less money you are paying per check. So go higher,

when you can.

5. Quetext

Whitesmoke is

another one of the popular editing tools, that is used by many pro bloggers.

Their new layout has attracted a lot of people to it, and I am considering

testing it for some time to compare it with Grammarly again.

And as any editing

tool, it can’t be complete without a plagiarism checker, so there is one that

you get to use with other tools. There are no free trials.

And you need to

either pay yearly or for 3-years if you want to save so much.

And you get access

to the plagiarism checker in their different packages, so see the one that

suits your need from here, and then use it to edit

your post, and check for plagiarism as well.

Small SEO tools is a

set of free tools that you could use to help you with your SEO. There are

different tools to use beside the plagiarism checker like the Word counter,

grammar check, reverse image search and what is my IP.

plagiarism by pasting a web page, if you have your post published, or by

uploading a doc file, or by pasting it directly in the box that appears to you.

1000 words per search. Just cut your posts in part, if you need to search for

more than that.

Great tools to use,

if you are limited with your budget.

Plagiarisma is

another tool that helps you check for plagiarism. You could even do a grammar

check from their site.

You can do a quick

search from their site, or signup for free.

12. DustBall

Dustball is a

project created by Brian Klug. it is created to do a plagiarism check. There

are different plages with different languages for people who want to visit the

In 2017, the ability

if you care about these things or you need it to give it to your teacher and so
