tools to check duplicate content

If you have been blogging for a while, chances that you have faced content scrapping at least once.

It becomes a part of the web. Anyone can copy your content and publish it to their blogs without any permission.

While you cannot stop someone from copying your contents, but it’s your responsibility to find out who is copying your content and protect it.

The main problem of content copying is, it creates a lot of duplicate content on the web. It decreases the credibility of your original content and you may get penalize by Google for duplicate content issues. So it’s always a good idea to check who is copying your content.

In this post, I am going to share 7 free tools to check duplicate content. These tools help you to check the originality of a guest post or if someone copied your existing posts.

Using Google Search is the easiest way to find who has copied your content.

7. Google Webmaster Tools

Google Webmaster Tools is not a duplicate content checker tool. But it can help you to find the content scrapper sites. Just go to your site on the Webmaster tools and click on Search Traffic > Links to Your Site. Check ‘Who links the most’ list.

If there is any site that links a lot of your site and it is not a social network or bookmarking site, then it might be a content scraper site. Just go to that site and check if it copied your content.

 Get Email Alerts When Someone Published Your Content

Above tools help you to check the posts that already been published, but what about the post that your are publishing now?

Someone might copy your latest posts. The best way to get notified when someone published your post is, through Google Alerts.

Google Alerts is an e-mail notification service that will send an email to you when it finds the something on the web that matches your keywords or phrases. Just pick a unique phrase from your blog post or the title of the post and create a Google Alerts. You can use double quotes to get the exact match. Google will send you email alerts as soon as it gets the phrase elsewhere in the web.

    Hi Istiak,
    I totally agree with you, and I think it’s also hard to stay unique and original, that is why i prefer to check myself and use plagiarism checker as well, but I use Unplag, which has launched free plagiarism checker – It is fast and safe, so I’m sure that my papers won’t be publish elsewhere. Also it helps me to see plagiarized arias, if I have cited the source wrong, or even forgot to cite, which might be as well.

    Thank you for your list!
    Have a nice weekend.

      That’s why I suggest to using Google Alerts to get notification if someone copies your content. If you read the last portion of my post, you will understand. BTW thanks for your kind words.

    I have never thought you could set an alert for email focused on a particular phrase! That’s a nice way to stay informed! I wonder if it works well.
    I use copyact for automatic protection of my website and it is also recommended for bloggers.
    All the best,

    Thanks for this great article. Always good and to the point content. What do you usually do when you find other people re-using or scraping your content? These tools & tips are great to find out where your content is used without authorization but would be useful to know as well how you handle this situations when they occur to protect your hard earned content and duplicate content penalizations.

      The best way to deal with it is, ask them to remove the copied contents. But if they are not kind enough to do that, just report Google to remove copied content.
