5 Best Online Plagiarism Checkers

Plagiarism is serious, but it is still highly common. It has become an epidemic across our education system too. As a website owner, there are two reasons why you should keep an eye out for plagiarism. First of all, you should consider running your website content through any of the best online plagiarism checkers available out there before posting it on your blog or website; even if you did not mean to copy someone, you might have accidentally strung a few words together in an order that would cause your website to fail for plagiarism.

You should also consider scanning the web periodically in order to make sure that no one is copying your content. Not only do you want your website or blog to be as original as possible, but you also have to realize that having copied content on your website can cause your page to fall in the search engine rankings very quickly, especially after the recent Panda update.



Copyscape is one of the most popular online plagiarism checkers out there. You can either copy and paste your content into this online plagiarism checker for a scan, or you can enter your URL to check for copied content.

Copyscape is inexpensive and easy to use, but you do have to purchase credits in advance.



PlagiarismDetect provides a premium online plagiarism checker. The site is easy to sign up for and use, and even beginners should have no problem getting accustomed to the service. It does provide a very intensive scan, but the cost can add up quickly for those with large websites.



Plagiarisma allows you to enter your website’s URL, copy and paste the text to be checked or upload a file of various different formats. One advantage of this free accurate plagiarism checker is the fact that it supports over 190 languages.

There is a handy free version for those who are on a budget, but the paid service is a better option for those who have a lot of content to check. It is probably the best free plagiarism checker that you will ever come across on the web.



If you are looking for a free service, you might want to try Duplichecker. Since Duplichecker actually checks every piece of text, some argue that it is more thorough than some of the other tools that are out there. As with Plagiarisma, you can either upload a file, copy and paste the text to be checked or enter your website or blog’s URL.

If you register for the service, you can conduct unlimited plagiarism checks each day. Even unregistered users can complete three checks per day, making it the coolest among all other online plagiarism checkers.



ArticleChecker is another free plagiarism detection service. Although it is not quite as thorough as some of the other online plagiarism checkers that are out there, it is still a handy tool.

You can use it to compare your website or blog post to results on both Yahoo and Google, but you will have to conduct two separate searches in order to check both sites.



The free online plagiarism checker offered by SmallSeoTools.com is really cool and efficient with no limitations at all. The interface and detection method are also quick and quite accurate. You are surely gonna love it!



Although there is really no foolproof way to check for plagiarism, using one or a combination of these tools can help to prevent you from inadvertently copying someone else’s content, and it can help you to find out if someone else has been using your words on their website or blog.

Since doing so can help to preserve your site’s originality as well as its search engine rankings, it is worth your while to use one or several of these online plagiarism checkers on a regular basis.
