Are you certain that the content you’re publishing on your website is 100% original?

Steering clear of plagiarism is a top priority for content creators, educators, businesses, and others in order to maintain credibility and avoid legal issues – among other things.

While Copyscape has long been one of the most well-known and popular options for plagiarism checking, the range of available tools has expanded significantly, with various features designed to meet people’s unique needs.

In this article, we will cover the basics of plagiarism – what it is, why you should check for it, how to check, and what to do if someone plagiarizes your content – before highlighting some of the top alternatives to Copyscape, helping you keep your content unique and valuable.

What Is Plagiarism? 

Plagiarism is when you use someone else’s work, whether words or ideas, and present it as your own without proper attribution.

Plagiarism can range from directly copying someone’s work to closely paraphrasing something without acknowledging the source. Sometimes, it’s purposeful, while other times, the perpetrator might not even realize they’re doing it.

Regardless of intent, plagiarism is a widespread problem that is difficult to combat – but the first step is detecting it.

Why It’s Important To Check For Plagiarism

The consequences of plagiarism can be severe – you can lose credibility, harm your reputation, and even face legal repercussions.

Here are a few reasons why it’s essential to check for (and avoid) plagiarism:

• Prevent legal problems. Engaging in plagiarism or copyright infringement can expose you to a range of potential legal issues.
• Maintain your reputation. Trust is vital. But why should audiences trust you if you’re stealing somebody else’s work? Checking for plagiarism is crucial to preserving your reputation and trust with your audience or customers.
• Preserve your SEO efforts. Google and other search engines are actively trying to crack down on plagiarism and will penalize any plagiarized content. This can hurt your website’s ranking and visibility.

How You Can Check For Plagiarism

There are a handful of different ways to check for plagiarism, including:

• Manual checks. This is precisely what it sounds like: manually reviewing content for plagiarism by cross-checking text using search engines and academic databases. If you’re examining a small chunk of text, this can work, but it can get unwieldy fast.
• Use alerts. It’s possible to create your own plagiarism checker by setting up Google Alerts. Simply enter your content into the search query field and let Google know how frequently you want it to alert you of copied content. While not a totally accurate or complete method, it can be effective at times.
• Monitoring services. You can use existing tools that help flag unauthorized use of your content. They do so by scanning the internet and leveraging algorithms to detect plagiarized content.
• Online plagiarism checker tools. Software and tools designed specifically to analyze content and run a comprehensive check for plagiarism.

While checking text for direct plagiarism is one thing, identifying paraphrased content or ideas is much more complicated.

And while we will highlight many useful tools in this article, it’s worth remembering that no tool is perfect.

With the sheer amount of content available and more being produced and published every second, it’s nearly impossible to complete a full check. Hence, why plagiarism is an ongoing issue.

What To Do If Someone Plagiarized Your Content

So, what do you do if you discover that somebody else has plagiarized your content? Here are a few steps you can take:

• Collect evidence. Take screenshots, make notes, and save any URLs as proof of the offense.
• Contact the perpetrator. As we mentioned earlier, sometimes, plagiarism can be an innocent mistake. No matter the situation, we recommend contacting the offending party and requesting that they either remove your content or label it with the proper attribution.
• File a complaint. If that doesn’t work, you can file a Digital Millennium Copyright Act (DMCA) takedown complaint, which will send notice to the service provider (e.g., Google or web hosting companies) to remove the content or face legal liability.
• Seek legal advice. If the case is particularly egregious, or the above steps fail, you can consider speaking with a legal professional.
