Plagiarism online is a real issue, and an issue which simply cannot be ignored by the professional content marketer. A lot of hard work goes in to the production of high quality unique content, and the very thought of others trying to get a free pass and benefit themselves from our hard work is a tough thing to bear. So what can we as content writers and content marketers do to safe guard ourselves from plagiarists?

For blog owners, inserting an RSS footer on each new item within a feed works a treat against scraping bots. For business websites, disabling the ability to copy and paste text from web pages is a good – yet not fool proof – method of stemming content plagiarism. As well as these on-site methods to battle against plagiarism, there are also a range of tools online which aim to aid you in detecting plagiarised content before it gets published and also keep tabs on any web pages that knick your content in the future.

Five of the best online content plagiarism detectors

Let’s take a look at the 5 top anti plagiarism tools available to content marketers online, in no particular order of favouritism.

1. Copyscape – website.

The good: A trusted tool, good detection rate, some core features free.

No list of plagiarism detectors would be reputable without a thumbs up for Copyscape. Considered to be the original tool for detecting plagiarism, this tool has barely changed over the years and offers a no thrills user interface which gets the job done. In its most basic form Copyscape allows one to input any URL and scan for web pages which share the same content. Also of note is Copyscape Premium and Copysentry, two paid features which allow a content marketer to keep track of content and get the heads up towards any web pages that steal content, and also check content before it gets published online through uploading.

2. Plagspotter – website.

The good: Well designed user interface, good detection rate, ability to scan full websites.

I had only heard of this tool on April 15th from a commenter on our Copyscape blog post. Plagspotter is a well designed and very modern content plagiarism detector, which functions in much the same way as Copyscape. Plagspotter boasts well over 1000 daily users of its service and it offers the rather neat feature of allowing a content marketer to scan a whole website for duplicate content. This makes it a great tool for website designers and developers, not just the content marketer. The Plagspotter API also allows users to check both online and offline content for plagiarism. I recommend checking out this service as an alternative to Copyscape.

3. Duplichecker – website.

The good: Excellent copy and paste function, solid detection rate, reliable.

Duplichecker is an online software program which differs in initial user interface to any of the duplicate content detectors on our list. A very effective tool, Duplichecker allows you to copy and paste content in to its box with a maximum 1500 word count and search the internet for any websites that share the same or some of the same content. This is great for both online and offline content checking, to ensure that your content is unique. I have personally used Duplichecker a number of times when designing and developing websites. It is easy to use and best of all free.

4. Quetext – website

The good: It’s completely free and it works.

Quetext is a new find for us. This service works in the same way as Duplichecker, but the Quetext website is more modern. Simply copy and paste your text into the box, and press go. You will be presented with a list of URLs with identical or near-identical copy to your own, if there are any. This plagiarism detector is also available as a widget, should you wish to publish such a thing on your website (check out the bottom of this article to see the Quetext widget in action).

5. Copyleaks – website

The good: A good alternative to Copyscape.

Copyleaks works in much the same way as Copyscape. You paste a link into their search box, press go, and Copyleaks then checks your link against the web and lists any websites with the same content. Importantly – for developers at least – Copyleaks also has a published API, so you can include it as part of any software products you create and sell. To use this content plagiarism detection service, however, you do need to create an account. Thankfully, a basic account doesn’t cost anything. We recommend this service if Copyscape isn’t your bag.

    Hi Jakk,

    A really great list. I used a desktop client a short while back for checking content against the web and it worked a treat, yet my computer crashed, and now I can not find it online anywhere to buy again. Do you know what this could have been?

    Duplichecker is a great tool for content marketers, I can vouch for it if anybody tries it.
