Google’s Matt Cutts says 25-30% of content on the Web is Duplicate Content.
Okay, let’s say, you publish a long 5000-word blog post, putting in hours or even days of comprehensive research and creativity to draft that piece of content. And the next day you find one of your competitors shamelessly plagiarized the whole of your content and published it under his/her name.
You will be furious, right? Who wouldn’t be?
Especially when search engines rank that plagiarized content over the original one.
And here’s another bummer, you would never even find out if your content is being plagiarized across the web without using effective Plagiarism Checkers.
On your luckiest day, you might catch your competitor doing such stuff but believe me, competitors are the most cautious people when it comes to copying content.
The culprits will always be some newbie or anyone who is doing it intentionally to earn a quick buck.
For the owner of a website, it is important to have content that is plagiarism-free to rank better and faster on search engines, and this holds relevance especially if you outsource the content for your website.
Checking the content of the outsourced article is vital for a webmaster or a blog owner in order to safeguard the authority and originality of the website.
Though Google has said many times in the past that it doesn’t penalize duplicate content, instead makes groups of similar content and shows the most relevant and engaging content to the searcher using its smart AI and algorithms.
But that being said, plagiarism is malpractice that not only creates a bad user experience but also degrades the quality of content available online and should be stopped by all means.
Whether you’re a student, writer, professional, or a business, plagiarized content can harm your reputation.
That is why a good plagiarism checker tool is recommended at all times now if you are into content generation.
