What is unique content?

Search engines value unique content that you’ve taken the time to craft for your audience. However, in the early days of search marketing (and still now), many try to avoid doing the leg work and instead plagiarise others’ work.

Plagiarism is the act of copying someone else’s work and attempting to pass it off as your own for personal gain. It is unethical, and in some cases illegal, to plagiarise someone else’s work. Crucially, with regards to online content, plagiarism can significantly harm your search engine optimisation (SEO), meaning Google will not rank your content highly in its search results.

A simple example of plagiarism would be finding a webpage or blog post that covers the topic you need, using the ‘copy and paste’ function to lift that content from its original source, and then using it as if it were your own work.

So if you want to keep in Google’s good books, when you write copy that will be published online, whether for a website or blog, you should take care to check that your content is unique. This is particularly important if you are using an existing piece of content as the basis for your own work – yours needs to be adequately different to be read as unique.

Equally, even if you are writing a piece of content from scratch, it won’t hurt to do a little check down the line to ensure your content has not been plagiarised by someone else.

Why use a free plagiarism checker?

If your aim is to produce quality written content that is of real value to your readers, it is essential to check for plagiarism. It’s no exaggeration that content is king in the online world – that’s the driving force behind current SEO practices.

Take this essential step to protect your original content by learning about the different kinds of plagiarism, and avoid any unintentional plagiarism on your part. This will help you establish a reputation as a producer of excellent content and develop a solid foundation for your SEO.

How to check unique content online free: 7 tools

The good news is there are some great free tools to check your content is unique:

1. Duplichecker

Duplichecker is one of the most popular free tools out there. It is handy as it incorporates other automated processes like checking your spelling and grammar. The user interface is simple: just upload or copy and paste your content into the text box and wait to get your results.

You don’t need to create an account or enter your email address – Duplichecker will simply do the work for you. The only negative is that you are limited to 1000 words per search.

2. Copyleaks

Copyleaks is a free tool with a focus on accuracy and providing detailed information. The only catches with the free version are that you must create an account and you can only do 10 free scans per month. For this reason, it may not be a good option for people who produce a lot of content.

Checks can be done via plain text, a URL or uploading a file. In your account, you will find all your previous scans are saved, and there is a bonus grammar checker.

3. PaperRater

PaperRater is an all-round content checker that includes plagiarism detection, so be sure to select the plagiarism checker when configuring your webpage checkup.

With a little setup to do, this isn’t the fastest plagiarism checker out there, but the results are worth the wait. You also get spelling and grammar checks, a readability score, alternative word suggestions and a few other tabs.

4. PlagScan

PlagScan is aimed at students, but it is also good for online content. The interface looks a little cluttered, and you are required to create an account, but the ‘free trial’ allows you to do 20 scans. Import text via URL, uploading a file or pasting plain text into the box.

5. Plagiarism Checker

Though the interface looks very outdated, Plagiarism Checker is simple to use. Simply paste your text and click the ‘search’ button. It’s not the most accurate of tools, but it doesn’t impose any limitations on the user and can be very helpful for SEO purposes.

6. Plagiarisma

This one analyses content through Google and Bing to see if similar content exists anywhere. It makes it easy to identify copied content and is helpful for checking your online content for SEO purposes.

7. Quetext

With a slick, simple interface, Quetext requires you to copy and paste your text into the box and click ‘Check for plagiarism’. This is the only way to import text, but you will get results swiftly to simplify the process.

Something to consider

These are great solutions for how to check unique content online free, but they are limited. There is some uncertainty regarding the accuracy of plagiarism checkers, particularly when you use free options.

Generally speaking, these free tools are sufficient for your needs, but they don’t check absolutely everywhere. They tend to scrape content found through Google, Bing, Yahoo, etc. This is often all that’s required, particularly for SEO purposes, but it is a limitation that you should be mindful of if you’re publishing sensitive content or you have outsourced your content writing to someone else.

Whether you’re a student writing academic papers or a freelance copywriter, these tools are a powerful resource for ensuring your content is unique and original.

Frequently asked questions

Still got some questions? We’ve answered a few below:

How do free plagiarism checkers work?

They scrape through the index of websites from search engines, using an algorithm to check how your content compares to what already exists.

Are plagiarism and copyright infringement the same?

If the plagiarised content has a copyright sign in the website footer, you could potentially be sued for infringement.

How can I report plagiarised content?

The simplest method is to use Google’s Copyright Removal Tool. It requires you to report the page and provide supporting evidence. The result can be the removal of the page (and, potentially, the entire site) from Google’s index.

Is there a difference between plagiarised content and duplicate content?

Yes. Duplicate content is when there are 2 copies of the same body of text, which can happen within your own website. It may be damaging to your SEO, but it is not plagiarism.
