Top 5 Free Duplicate Content Checker Tool Online

Best Free Duplicate Content Checker|There is a lot of confusion regarding the Duplicate content and it’s effect on Search Engine Optimization and content marketing.

According to Forbes, there are 2.5 quintillion bytes of data created daily. So if you want to stand out you have to produce original and meaningful content anyway. The competition is getting really hard for all the publishers out there.

In this time where the content is considered as the king, the duplicate content issue is probably one of the most striking problems around. In this post, I will provide you with the list of 5 free duplicate content Checker Tool which you can use to maximize your content marketing efforts and maintain your originality.

First of all the quick list of 5 Top Duplicate Content Checker Tool Online

  • Small SEO Tools Duplicate Content Checker
  • PREPOSTSEO’s Online Duplicate Content Checker
  • Dupli Checker

So let’s start the discussion!

What is the Duplicate Content Actually Means?

In simpler words duplicate content is some content block/text/images which are copied from another source in an exact manner or rephrased or modified for reuse.

Sometimes the source is mentioned, but most of the times it is taken from the source without assigning any credits to the source. It simply means stealing another’s property.

According to Matt Cutt, almost 25-30% of the total web’s content is duplicate.

But Why You Should Bother About the Duplicate Content?

If you are a content creator or blogger you probably know the value of the real content. It takes a lot of time and research to produce high-quality content.

Content is the pillar of any publishing platform. If you are an online publisher than you probably know the value of unique and original content in terms of getting search engine traffic.

So if someone just copies your own content and reproduce it for their own purpose without assigning any credit, then all your hard work has just been nullified.

But not only as a content creator, if you are a content marketing professional or simply a business owner who needs frequent content from content writers then you can also face the same problem of this content plagiarism.

If you are not careful then you may receive a bunch of duplicate content from the content writers which is of no value. This may also lead to Copyright infringement which is completely unaccepted in any case.

But Is There No Way to Stop This Duplicate Content?

Hopefully, Google is all aware of the fact and has taken some very serious steps to fight with this duplicate content issue.

Below is a quote from Google’s latest quality evaluator guidelines.

“Important: The Lowest rating is appropriate if all or almost all of the MC (main content) on the page is copied with little or no time, effort, expertise, manual curation, or added value for users. Such pages should be rated Lowest, even if the page assigns credit for the content to another source.” – Google Search Quality Evaluator Guidelines July 2018

According to Google’s Andrey Lipattsev Google does not imply a penalty for using duplicate content but also doesn’t add any true credibility to your content which can help you to rank better in Google.

Google simply loves unique content which adds value to its users. So if you are just using duplicate content, then Google will simple devalue your content.

In addition, if you notice someone stealing your content without your permission you can request to have it removed by filing a request under the Digital Millennium Copyright Act. By filling this request here

That’s it!
