5 Simple Online Services for Checking Content Plagiarism

Many of us have faced the problem of dealing with plagiarised content, either while reviewing guest articles by low-quality bloggers, or inadvertently using common phrases in our own writing.

Even the most skilled blogger cannot possibly be familiar with all the pages of content which are already online in a specific niche. When writing about a particular topic, it is very easy to use phrases which are similar to ones used on other sites.

If similar issues are being discussed in the blogosphere, it is not outside the realm of possibility that some similar content may inadvertently appear—even if the work was made by the blogger personally and not copied and pasted from someone else’s site.

For that reason, running a plagiarism check should be part of your standard procedure of checks and balances before accepting work from a blogger. These five online services for blog post plagiarism checking can help you weed out any duplicate content.


Copyscape has the advantage of being easy to use: simply paste in a URL or a section of text you wish to check for plagiarism.

This well-known service charges $0.05 per search. Sign up for an account at the site to get started. You’ll need to buy credits in advance, whether you end up performing plagiarism checks or not.


This is a premium service for people who work with large text/content arrays. It gives an option to test the service free of charge right on the home page. The results will be available after a few-click registration. The pricing is $0.05 /1 page, and it takes less than 20 seconds to perform a scan of any size. The checker suits professional content writers and bloggers who outsource their content writing.


ArticleChecker is a free online service which is very simple to use. Simply copy and paste the blog post you wish to check into the text box on the site, or provide the article’s URL and click “Compare.” You can choose to check your text using Google or Yahoo searches. And for extra protection, you can choose to run your search twice, once against each search engine.

If any matched phrases are found, the results will show the number of times that content appears online. While this tool is very easy to use, you have no way to control the level of sensitivity of the search you are conducting, so it can miss results that the other tools will catch.


Duplichecker is a free online service which allows you to copy and paste your text into a box, upload the post file, or enter the URL of the website you would like to check.

Unregistered users can perform three searches per day. Registered users can perform unlimited searches. The service checks each piece of text on a line-by-line basis to look for duplicate content, which suggests it’s a bit more thorough than some of the other tools.


Plagiarisma has the advantage of supporting over 190 languages. This plagiarism detector allows users to check for duplicate content on Google or Yahoo by copying and pasting text into a text box, entering a URL to be checked, or uploading a file. Accepted file formats include .doc, .docx, .rtf, .txt, .odt, and .pdf.

Each query is limited to 5,000 characters if you are using the free version of the tool. If you have a long blog post you wish to check, you will need run more than one check on the text, or register with the site. Signing up is free and will give you faster and better results.

This tool will show you results from Google and Yahoo, which will allow you to determine whether the text was copied word for word, or simply contains similar phrases to the blog post you are checking.

Registered users are able to use the service up to five times per day, which may not be enough if you have a large volume of checking you need to do on a regular basis. To access all the features available through the service and do more searches, you will need to buy a premium membership.

Get to know your bloggers

Checking a blogger’s work is a good way to ensure that it is up to par, but there are some things you can do beforehand to increase the odds that you will be working with a good quality blogger. Most importantly, the person should have some experience writing for the web, even if only for their personal blog.

Make a point of checking references to make sure that the people you are working with are trustworthy. Someone who holds him or herself to a high standard in his or her personal life will likely carry the same attitude through to his or her work.

Take the time to ask writers some questions, either by email, phone, or Skype, to determine their level of knowledge about the importance of unique content and meeting deadlines. For your part, have a copyright and plagiarism policy that explains how you check and will respond to any copyright infringing content. Removing the temptation to copy text “just this once” because a blogger is rushing to meet a deadline may nip the issue in the bud.

Don’t underestimate the value of original content. Apart from its rankings potential, it’s probably the best way to manage your blogging reputation, so it’s worth it!

Follow this simple rule: better check twice than get penalized once. Make content checking a part of your daily routine.

  1. Great tools to help check for plagiarism. Thanks.

  2. Hi Kimberly, Thanks a lot for your post on plagiarism. I cannot imagine how much time i spend writing a post while someone somewhere is hungrily waiting to swallow quality baked content. Its just not fair. I also got to learn of the Articlechecker which i have seen is a good one and will use it. Thanks for the guide to help fish out the content bandits.

  3. Except copyscape all are new to me…hope i will find these services useful…i tried dustballs plagarism cheker earlier but that was not worth using :/

  4. wow nice list kimbersly… i didn’t know that there are so many goood tools available for plagarism checking…. :) will surely give a try to all of them and let you know my experience with all of them :)

  5. hi Kimberly ,
    nice you did a nice job listing all these cool tools at one place will be very useful for people like me to try each and every…..and people who were searching for such tools thanks

  6. Kimberly

    I’m a big fan of copyscape, this is a very important issue because so much people copy people’s stuff out here.

  7. I know most bloggers state in their guest blogging guidelines that all posts must be original, but I think we can take it a step further and say that submitted articles may be subject to a plagiarism test to ensure original work. Stating this may increase the quality of the guest posts we receive whether we perform the check or not. Thank you for sharing these great resources we can use to keep our sites clean from duplicate content.

  8. I use Copyscape and love their premium version, especially that it is so cheap anyone can afford it. I caught some posts there were copied from other blogs, in whole or just parts of it. Getting to know your bloggers is a great tip, especially if you want them to post more than once, but getting a lot of guest posting requests from people you don’t know dictates using one of the tools you mentioned.
    I’ve even seen some posts go unnoticed on bigger well known blogs, because they were “rewritten” in sense that it is the same post you can read on another blog, but in totally different words. Guess we live and learn :)

  9. I always use copyscape to check duplicate content. The only problem is that I am always short of credits. Thanks for giving some more links. This will help me to reduce my dependency on copyscape.

  10. Thanks for the lists Kimberly!
    That was exactly I needed.
    I did purchasing a content writing service, and these tools seems will work useful for me.
    Thanks for shared!

  11. Thanks for such a great inspiring. I only new about copyscape and articlechecker. others are actually new to me and I’m glad to learn more about them. Hope they give me a break-through in my blogs. I love the contents, keep up!

  12. Thank you a lot for such a great encouragement. Everything at first was new to me but I have to confess to have got a very crucial break-through! I like learning and making into active new skills and knowledge and your content falls under such. I hope they will actually help out. Thanks for sharing and I look forward into sharing more. Thank you for your inspiring information!

  13. Before posting any article on a website or blog, plagiarism check should be carried out. This will ensure that an article is unique and it avoids any allegations of copying another person’s work (article). I mostly use copyscape, I find it to be very accurate. It is also easy to use it just as mentioned above.

  14. These will be very helpful. Thanks a lot for the links. All except copyscape are new to me.

  15. Great tools! I guess most people will always default to the ole tried & true copyscape, but honestly there are probably some free tools out there that work just as well. Another one that I like is plagium.com. I’ve heard a lot of good things about it and some say it works just as good or better than copyscape in some instances.

    This is great! Thanks for posting.

    These tools work fine if you are prepared to enter in every post url. A major task if you have thousands of posts and want to continue to check them.

    Google should give credit to verified authors and then blacklist them if they copy/rewrite content.

    Some well known guest authors are without doubt the worst offenders in my opinion and its the responsibility of the domain owner to make sure they don’t rewrite content or risk being reported.

    Regardless of whether your domain has a high authority and is protected or not, you will pay the price if they receive multiple notices from different webmasters.

  18. really helpful for genuine content creators, except copyscape really don’t know about other similar tools. just got a question, is there some similar tool which allow you to check video duplication on different websites.

  19. Jacob says: 10/02/2012 at 6:11 pm

    If made a modification on the copied content, will this tool detect?

  20. Thanks for these – like others, I’d heard of Copyscape but not the others.

  21. Plagiarism is a menace to bloggers and glad i have found even more options to check my guest articles for plagiarism before publishing it on my blog so i don’t hurt my SERP and myself as its been proven that most freelance writers don’t care their only interest is to gain backlinks and traffic from their articles.

  22. Simply, amazing list of tools. Specially for content writers. Now my question is, how much tools are there in the market for content writers, which we can use to check the quality of content. Thanks!

  23. My method is very simple, i just take one para and paste it on google. If its copy paste it will show on results.

  24. I only User Copyscraper. It’s amazing tool.

  25. One of the best article i’ve ever seen.

  26. Nice Article About content plagiarism

  27. Thanks body, I check all Status amazing :)

  28. Thanks body Very helpful :)

  29. But I still think Copyscape is the best
