Google is always on the lookout for original quality content, so trying to plagiarise someone else’s blog post, can really harm your site.
You can also be penalised if Google sees that your website contains duplicate content within the same website, so running your new piece of content through a plagiarism checker should really become a habit, prior to posting your new blog post.
If you are looking for the best free plagiarism checker of 2019, please carry own reading this post in which I have put together 3 tools that do not require you to register nor to pay to perform a plagiarism check.
What is plagiarism?
Plagiarism is when you use someone else’s ideas and take credit for them.
This doesn’t just apply to text. Using images, videos, music or anything else that was not produced by you, requires you to cite the source of origin.
Here is what is considered as plagiarism:
- Using someone else’s work without giving them credit
- Using pieces of text written by someone else, without putting them in quotation marks
- Making others think that a piece of work is your own, when it actually isn’t
Google is never happy to find plagiarised work, so it is important that the correct steps are taken and that research is done to avoid plagiarism.
Check this video from S.Wood, showing what plagiarism is:
Types of plagiarism
There are many types of plagiarism, but here are 4 of the most common ones:
This happens when the person using someone else’s content forgets to cite the original source.
It usually occurs to new writers, who might not know all the rules that need to be applied when using third party content.
Despite being an accident, this type of plagiarism is still considered as serious as any other type.
Direct plagiarism is when the exact work that belongs to someone else has been used without quotation marks or attributions.
It is basically copying and pasting someone else’s content into your work.
If you wish to use the exact same words of an article you like, then you must put the text within quotation marks and cite the source.
Mosaic plagiarism can be hard to spot, as it entails using bits of text from someone else’s work.
This is also called patchwork plagiarism.
Self-plagiarism occurs when someone re-uses their previous work without letting the reader know that this was already used in the past.
This type of plagiarism is also called auto-plagiarism.
What percentage of plagiarism is acceptable?
Even after doing an extensive internet search, I was not able to find an answer everybody could agree on.
Some websites say it is acceptable to use up to 15% plagiarism, which if you ask me, I think it is way too high!
Other websites say 0%, 1%, 10% and so on.
I personally would not go over 1%.
Always make sure that the borrowed text is not all in one continuous block!
Tool #1: Small SEO Tools – Plagiarism Checker
Small SEO Tools Plagiarism Checker allows you to perform a 1000 words search by either manually entering the text, uploading a document, entering a website’s URL or choosing a file from the cloud.
Here is how to use it:
- Copy the text you want to check and paste it into the blank box. Alternatively, you can upload a file, either from your PC or from a cloud service
- You can exclude URLs or enter a specific one to check if you wish, but it is not necessary
- Click on “Check Plagiarism” –> Page will automatically scroll down to the results
- Check “Sentence Wise Results” to view results by sentence
- Check “Matched Sources” to view title, text and website where your plagiarised text appears
- Check “Document View” for a plain view of plagiarised text
Both the “Sentence Wise Results” and “Matched Sources” feature present a “Compare” functionality which will take you directly on the website where the plagiarised text is. This way you will be able to view the entire article.
You have the options to download or share the report if you wish.
This tool also offers you the opportunity to rewrite the plagiarised sentence. Clicking on “Rewrite Plagiarised Content”, will take you to the “Article Rewriter” tool.
I have personally tested the article rewriter tool, and I recommend you do not use it. Rewritten sentences never made any sense when I tried it!
However, the plagiarism checker tool itself is quite accurate and all the little features make it a nice free tool to use.
Tool #2: Plagiarism Detector
Plagiarism Detector also has a limit of 1000 words and presents the “Enter URL” and “Upload Files” features just like the plagiarism checker tool above.
This plagiarism detector is very simple to use:
- Copy the text you wish to check and paste it into the text box
- Click on “Check Plagiarism”
- Scroll down to see the results
- Click on “Match” text to see the article that presents the same text
There is no option to download the report, nor to upload a file from the cloud but you can upload files from your PC or search for text by specifying the URL.
There is also no “re-write article” feature, but given that this never works really well, I don’t think it is necessary to have it as part of Plagiarism Detector.
Tool #3: Prepost SEO – Plagiarism Checker
Prepost SEO – Plagiarism Checker also has a limit of 1000 words. There is no “Enter URL” feature but you can exclude the ones you do not want to include in your check, such as your own website.
Two features offered by this tool which are not available with the other two, are:
- Google Chrome extension
- Language selection
Having the extension installed in Google, means that you will no longer have to manually enter text in the box or upload a file, which is quite handy.
All you would need to do is install the extension, select text, right click on it and then click on “Check Plagiarism of Selected Text”.
If you still wish to do things manually, then here is what you need to do:
- Copy and paste the text into the box
- Click on “Check Plagiarism” –> Page will scroll down to results
- View or download report
Plagiarism results, matched sources and document view features are available just like in the Small SEO Tools – Plagiarism Checker. However, this tool also offers 2 additional handy ones:
- Grammar Results: Check if any grammar errors are present in your text
- Readability: View tons of statistics, such as unique words, keyword density and flesh readability
Conclusion: Checking plagiarism should become a habit!
There are many things that can help you make Google be your friend and one of these is certainly checking plagiarism.
Setting 5 minutes aside for each article you write, won’t take much of your time and it will also be worth it in the long run.
