6 Free Duplicate Content Checker Tools

Duplicate content is the worst enemy for any blog and it can cost you a lot if google founds duplicate content in your blog. Your blog can either get removed from the search engine or its ranking can be dropped for all your targeted keywords.

As you know TechMaish was a guest posting blog where most of the posts are contributed by the guest bloggers, internet marketers and business owners. I always checked my articles before publishing, however as you know most of the people are hiring writers to write articles on different topics and then publish on guest posting blogs.

A article written by a freelancer has always the issue of duplicate content, because of excessive load on the writer. OR the quality factor can be ignored by the writer which makes the article unprofessional and promotional one. I always checked my published articles on regularly basis to check if any of my blog article contain duplicate content. I am using different tools to detect duplicate content and some of them are great tools available for free. Although the tools are free, but if you buy a premium package then you can get accurate and detailed result for your searches.

      Rohit@ This plugin is good but it is only the way to stop people copying from you. However the tools can help you find who has copied the content.
