Duplicate content checker: Free SEO tools for your website

Duplicate content is the type of content that has been copied from another source, while not a piece of originally-written information. If you publish your own written content in more than one place, then you are likely to have duplicate content online.

When there is similar content in more than one website around the Internet, search engines find it difficult to determine which content is relevant for the query on their search engine. The main aim of search engines is to produce the best possible search results for their users. 

When plagiarized content is found, it is excluded from the search engine queries. Search engines apply sanctions on such websites, and the web owners can suffer traffic losses. Popular search engines like Google prioritize websites according to the value of the site’s content. Therefore, with plagiarism, your website will not be visible to your potential customers anymore. In the worst case, the penalty of plagiarized content can be imposed.

Due to this reason, website owners should use a free online plagiarism checker to ensure the content they are uploading on their website is free from plagiarism and has not been used elsewhere.

Since the Internet is flooded with websites and marketers use the content on the Internet in their marketing strategy, there is a high chance that you may be writing something that has already been discussed somewhere else. You might have penned down your thoughts from scratch, but it is always a good idea to pass your written article through a free online plagiarism checker before you publish it. Let’s take the example of a blogger who usually has to produce several blogs on the same topic.
