What is copied content?

Copied content is information that appears on the internet in more than one place. You might know it as simply copy and pasting, but duplicate content can also apply to information that is copied on different pages on your site, for example, a company description or ‘boilerplate’ that’s pasted on every page. In some cases, duplicate content might be used accidentally or used as a placeholder text and not removed, but this can all still negatively impact a website’s SEO.

Does copied content online really matter?

Yes! For starters, content you find online might be copyrighted, exposing you to legal issues if you re-use it without authorisation. Even if you do have the authorisation, it’s still not a good idea for you or the original content owner.

When it comes to how you rank in search engines, duplicate content can really damage your site’s reputation. Search engines know that their users want to find quality content which offers value, different opinions and accuracy. So if you’re found to be reusing someone else’s content to ‘engineer’ or ‘manipulate’ Google, then you’ll likely be penalised. Even if you’re not doing it maliciously, search engines can still recognise it, which can cause problems with Google knowing which parts of your content to display to users.

So, if you want to improve your website’s ranking, then investing in quality, insightful and original content which shows thought-leadership is the best way to go about it.

Finding the right duplicate content checker for you

When you are deciding how to check copied content online, it’s important to use the right tool for you. Writers of long-form text may choose to sample sections throughout the piece or use a duplicate content checker which can scan large documents.

Many of the available tools to remove duplicate content issues also have integrated spelling and grammar functions which can be really helpful. For some online plagiarism tools, you simply copy and paste the text, but in others, you can upload full documents in a variety of formats.

Top 3 plagiarism checkers online

Knowing how to check copied content online isn’t just beneficial for writers or content creators, it can be a valuable skill for business owners, bloggers, students and freelancers. There are a number of different tools writers and editors use to make sure the content they are creating is unique. Here are three of the market leaders:

1. Copyscape

Copyscape is one of the most popular ways to check for copied content online. If you want to paste in your own content and see whether it matches any other pages online, then you’ll need to pay for this advanced feature. Or if you want to check whether your published content has been duplicated by another site, you can use the free checker.

2. CopyChecker

Copychecker.net is a simple website that offers a free content checking service, ideal for snippets of text or longer essays. Simply copy and paste your text into the plagiarism tool and it will highlight any potential duplicates.

3. Grammarly

This popular editing tool also has a plagiarism checker included in its premium features. Grammarly can be used on a variety of platforms, with browser add ons, and it can also advise on word choice and sentence structure.

Other ways to check for duplicate content

There are a number of other simple ways you can check copied content online. One of the quickest is to copy ten words from the beginning of a sentence and search it using quotation marks. If you have a large body of text, it might be worth checking a few sections for copied content by searching different quotes on Google. You can repeat this process for random bits of text throughout your website.

There are also a number of other free programs online; however, these are likely to be less effective than paid-for services so bear this in mind if your work is particularly sensitive.

If you have used other content to help research your piece and want to check that you haven’t unintentionally plagiarised sections, then you can run a side-by-side version compare with tools available online such as Check Plagiarism’s comparison search.

The benefits of plagiarism checkers

There are a number of benefits to using a duplicate content checker. Each has different features, such as keeping a record of your searches so it’s easier to prove content is yours if someone else copies it. Some plagiarism checkers also allow you to specify the length of text that they analyse so if there’s just one section you want to check for copied content this can be quicker or more affordable. Certain online plagiarism checkers can also inform you what percentage of the text is similar to other website sources.

The downsides of duplicate content checkers

Though duplicate content checking tools can be incredibly useful, there are some potential things to look out for. There are limitations to duplicate content checkers, for example, free services may not be as reliable as paid tools. If you’re using free tools, we recommend using several to cover your back.

Importantly, if a page hasn’t been indexed by Google yet it probably won’t find it. Some can also be exceptionally sensitive, which means they may flag common phrasing, data or quotes which is almost impossible to remove without losing the original sense.

How to check copied content online isn’t yours

There is another side to the copied content subject, which is how to check whether someone else has copied your content or plagiarised your work. If you think another site or company has copied your content, then you can use Copyscape’s free service to check whether there are any matches to your site’s content.

You can also use Google Webmaster Tools to check links to your sites. If your content has been stolen, you can contact the site asking them to remove it or provide accreditation and a link if it is a high-ranking site. You can also contact the host of the website to complain about stolen content.

The takeaway

Never take the results of a plagiarism checker at face value – always exercise due diligence and judgement. And of course, the best way to avoid duplicate content is to make sure you use several sources and conduct wide research when creating your content, fact-checking as you write and using your own tone of voice!
