How does plagiarism affect SEO? 7 tools to make our content plagiarism-free

SEO or search engine optimisation means all the tools that are used to enhance the ranking of a website or a blog. 

These include many practices and strategies because every website owner wants its website to rank higher among the Google index and they try to stay away from practices as much as possible that can harm the SEO ranking in any way. 

Plagiarised content is one such issue that jeopardises the ranking of a website. Well, what is plagiarised content? 

What is plagiarised content?

In simpler words, the intellectual property of other people or sources used as your own. This can harm the reputation of both you and as well as the original creator.  

Although it is common knowledge among people that using plagiarised content is generally a bad practice, we still come across this issue very often. Plagiarism can be of different types. It can be direct plagiarism, mosaic, or accidental plagiarism.

Types of Plagiarism

  • The direct type of plagiarism is the most dangerous one because it means the writer has copy-pasted the exact text without changing anything. It is mostly the deliberate kind of plagiarism and the person who is doing it is well aware of it.
  • Then there is mosaic plagiarism. It can confuse most plagiarism detection tools and even search engines. But the problem arises when the original content starts to rank lower and most users don’t even realise that they are consuming the plagiarised content. However, if the original owner finds out about it then websites with plagiarised content can be banned forever.
  • Accidental plagiarism is the least dangerous as the writer is usually innocent in this case. As the internet is filled with information that is increasing day by day, therefore, it is very common that your content gets matched with somebody else’s data.

How does plagiarism affect SEO?

The consequences are pretty much the same for every type of plagiarism. The website usually gets penalised for plagiarised content. 

Also, plagiarism can highly affect the SEO ranking because the internet does not work like human brains. It cannot detect which content is original and which one is copied. 

This confuses the search engines and gives irrelevant results which can harm both parties. No doubt it affects the reputation and is also a waste of money. 

However, if you are in the SEO business and worried about plagiarised content, you don’t have to. The Internet is flooded with tools that can make your content plagiarism-free. Most of them are pretty authentic and work free of cost. 

Best plagiarism checker tools

We would suggest using these websites extensively as there is no harm in it also making the work of content writers much easier.

2. Check-plagiarism.com
