Top 11 Free Plagiarism Checker for Blogs

Avoiding plagiarism is essential for bloggers – it is why free plagiarism tools exist! Our list of the best free plagiarism checkers for blogs will help you clean up your copy before publication. Also, why do you need to use plagiarism checkers when writing content in the first place? Let’s talk!


Whether you’re an aspiring blogger, a professional content creator, or someone who simply likes to write online articles from time to time, plagiarism is a mistake. You might accidentally copy someone else’s sentence or paragraph word-for-word without realizing it, or, include statistical data without listing its source.

Plagiarism can affect both how readers perceive your content and how Google ranks your links through its SEO algorithm. According to statistical reports‌, duplicate content can be found on 29% of existing internet pages, meaning that a lot of content creators plagiarize by accident.

To avoid that, you can use free plagiarism checker‌ tools for blogs and other online content. These tools will let you double-check the originality of your content before you publish it online and risk copyright infringement and potential legal issues.

Reasons to Use a Free Plagiarism Checker

Why go through the trouble of using a plagiarism checker? After all, if you’ve written your blog post as an opinion piece or a creative essay, there shouldn’t be any issues – right? According to the University of Oxford‌, plagiarism is defined as “presenting someone else’s work or ideas as your own…without full acknowledgement”. What does this mean in practice?

Plagiarism is often related to academic studies, where students are often short on time and don’t have the energy or resources to write papers systematically. In desperation, students often resort to plagiarism instead of reaching out to a professional service that can help write a best essay‌ for them. Students across the world have set a precedent for plagiarism and are unfortunately often scrutinized for it.

According to published findings‌, 38% of academic students admitted to paraphrasing or copying a few sentences from other sources without citing them. Moreover, 36% do so from internet resources, including blogs, which makes it even more important for you to use a free plagiarism checker in your content. Here’s why using plagiarism checkers is a good idea for your blog content writing:

  • Great tools for everyone from students to bloggers and literature writers
  • Maintain your online integrity and earn readers’ trust
  • Plagiarism checkers crawl the web for copies of your writing in mere seconds
  • Plagiarism checker tools use percentage values to give you an objective plagiarism estimate
  • Revise and rewrite your content properly before publishing it

Content Formats you can Use a Free Plagiarism Checker On

As a blogger, you are likely to create various types of content for your blog site. Differentiating content is important to ensure that your readers engage content and that your SEO ranking is healthy. But what does this mean for plagiarism? Any written content published in your name can be subject to plagiarism checks online.

Whether you create social media posts or blog articles, someone somewhere will be on the lookout for plagiarism. People whose intellectual property (IP) you’ve infringed on often won’t be happy about it. This is why protecting your blog content under a Creative Commons license‌ upfront is a good move. Here are the types of content you might want to pass through a free plagiarism checker before you put them online:

  • Website content (homepage, about us, contact us, etc.)
  • Blog content (articles, infographics, statistical reports)
  • Social media content (status updates, short-form tips, essays, questions, etc.)
  • Metadata content (title and description of each webpage on your site)

Keeping these content formats in mind when checking for plagiarism in your writing should cover most of your bases. Remember to also periodically pass your content through plagiarism checkers after it was uploaded. This will give you a great indication of whether someone, accidentally or deliberately, used your content somewhere online without attribution.
