How To Check Duplicate Content – A Detailed Guide With Example

Duplicate content check is a very necessary practice to be exercised by content creators and website owners as well. This is because the search engines like Google are developing strict rules for the websites which generate duplicate content.

How To Check Duplicate Content

Before we jump into the main topic that is “How to check duplicate content”, let us first learn what duplicate content is:

Duplicate Content:

Duplicate content, it is very obvious from this term that the content which has been copied from any other source is called duplicate content.

A lot of creators and website owners have started to duplicate content from websites with good ranking to rank better. Since search engines like Google function are entirely based on algorithms, earlier this kind of plagiarised content couldn’t be detected. Now that things have changed, and the internet is the medium for the limitless opportunities for people to make money, search engines had to develop algorithms for duplicate content check.

Duplicate content is not always intentionally created because over 2 million blog posts are being uploaded online every single a day which exponentially increases the chances of content being similar to another. These similarities could be adjusted through many online tools. While search engines still need to work on their algorithm function to become adept at the duplicate content check, many online tools have been developed which work very precisely for duplicate content check. Search engines like Google can detect suspicious behaviours such as whether or not a website is using bots to create and upload posts according to algorithm functions.

While search engines take time to detect such behaviour and have relatively less precision for the duplicate content check, the process of removing such websites when reported is done remarkably fast. The basic structure of search engines or any online tool for a duplicate content check is they pick blocks of content of a website and match the level of similarity of the content with any other site on the World Wide Web. The content that completely matches the content of any another website or has a larger percentage of it copied from another website could be considered as a duplicate content.

By 2016 the amount of duplicate content floating around the web was between 16 to 25 per cent. The process of handling duplicate content by search engines like Google is quite different than what we assume it to be. Here are some points that would give an idea about what happens to duplicate content and how is it being handled by search engines like Google:

Google Removes the Duplicate Content From the Search Results

As mentioned earlier, search engines like Google’s work are entirely based on a bunch of algorithms. These algorithms after detecting substantial blocks of a website which completely r partially match any other website, Google compares both the sites based on some parameters to judge and identify which website is authentic and which one is not.

These parameters include domain authority and other statistical facts of the website. The website which Google finds authentic appears of the Search results, while the one with duplicate content is kept hidden from the search results. Many times it has been seen that some websites copy the content from other websites which rank higher on Google. Being detected several times for duplicate content, the website loses its tendency to appear in search results.

Search engines like Google want the readers not to come across the same content again and again. Therefore through a duplicate content check, it removes such websites from the search list. There is no specified penalty for copying content but getting removed from the search results could be taken as punishment itself, for there is no point to have such a website. It is highly advised not to duplicate content from any website.

Get It Removed:

 There are lots of necessary content on Google which shouldn’t be copied and therefore the respective owners of the content being copied can report the website which duplicates content by requesting search engines to get it removed. While unique content is more likely to appear on search engine results, content creators have therefore become more cautious about their content being duplicate or similar to another website to some extent.

This is fairly possible because of such a huge number of articles, blog posts, and journal being published every single day. There are millions of blog posts available on the internet, therefore the chances of any content being similar to another are very high. This being the reason, people who have taken blogging and online industry seriously are practising duplicate content check.

While Google can detect it only after the content has been uploaded, there are online tools, which can perform duplicate content check while the content has not been uploaded. There are many online tools which perform the duplicate content check, and a lot of them have been verified by Google itself. These tools are very precise and detect similarity way easily through duplicate content check.

Because of such a huge number of content on Google, it could be difficult to compare and detect plagiarised content through duplicate content check. Whereas these online tools have to be handled individually, to perform a duplicate content check, which means the content creator or website owner has to upload the entire text of the content to check whether or not the content is similar to any other website.
