Checking plagiarism manually is very time-consuming, exhausting, and practically impossible to do. There’s Google has indexed billions of webpages and is continual doing so. With that in mind, one of the major things Google does is looks for content that is plagiarized.

While it may be impossible for one person (or a team) to check if their content or third party content is plagiarized, there are now tools and applications that can really assist writers with this problem. With the evolution of machine learning and AI, plagiarism checkers have evolved to the point where they really can assist writers in verifying their content.

What does a plagiarism checker application do?

A plagiarism checker does what it sounds like it does – it checks plagiarism. It will scan millions of webpages to see whether or not there is overlap in paragraphs, sentences and even tone.

Several applications and tools are available for the users who want to check plagiarism.

There are two types of plagiarism checkers available to the public:

  • Mobile app plagiarism checkers
  • Desktop plagiarism checkers.

The majority use mobile phone apps to check plagiarism. These users are students, teachers, content writers, lawyers and article writers, etc.

Tools and apps made this whole exhausting process a very smooth process. By using a good application and tool, you’ll be able to plagiarism check your content in minutes.

Through these apps, you can create unique and good-quality content of your own.

Why is a Plagiarism Check good for SEO?

For Search engine optimization, using plagiarism checkers is a a regular strategy, especially when you have a 3rd party writing content. Ultimately, you’re looking to reduce the chance that there’s duplicate content being posted on a website you own or operate.

The Google algorithm is quite intelligent, and is able to understand whether you’re posting that new article as copied content, or original content. Since Google has access to billions of web pages, it’s easy for them to compare your content vs. everything else that’s out there.

If you have duplicate content, you’ll see issues with the actual indexing of your web page. In Google search console your web page may have two statuses associated with it.

  • Crawled – but not indexed
  • Discovered – but not indexed.

If you have either see either of these two crawl statuses, you could have a plagiarism issue with your article. In content marketing, content is extremely important. However, it’s not advantageous for a user to read content that may be duplicated from another source, especially if it’s not cited. It’s important to have someone on your team that can look out for these technical SEO / content issues, thankfully – I know how to handle these situations :).

For my personal blog and articles I write – I don’t normally use plagiarism checkers. I find myself regularly having to use these tools due to guest bloggers.

My process for guest bloggers is as follows:

  1. Agree upon the backlink, topic and strategy and method of handover of the content (Dropbox, Google drive, Google docs, Microsoft Live)
  2. Agree on a time / date that I will receive the content
  3. Receive the content on an appropriate date
  4. Plagiarism Check – to ensure that the content is plagiarism-free. Sometimes, when agreeing upon the topic, I’ve had guest bloggers provide links to Copyscape or plagiarism detectors upon delivering the blog to me.
  5. Grammar check – Here’s where I look for grammatical areas and issues (proofreading)
  6. Reformatting of layout and additions to content for uniqueness
  7. Publish article

As you can see, plagiarism check plays a crucial role in my content strategy for guest blogging.

1 thought on “Best plagiarism checkers for digital marketers”

  1. LOL it is really hard for me to put smallseotools on my favourite list. I have tried SmallSEOTool as many writers suggest but according to me the level of accuracy of this tool is pathetic. Even I was scolded by my supervisor which is disappointing.
    Later, I accidentally discovered the plagiarism checker pro of LittleSEOTools and compared it with quetext. The result was quite satisfying. As you know Quetext has limited search, so I use plagiarism checker pro of LittleSEOTools as an alternative. It is a free tool with unlimited searches but it has a drawback. You can only search 1k words at a time which is a pain 🙁 but I have unlimited searches 🙂.
    The most important thing is my Professor is now satisfied with my writing.
