Effective Tools and Tips to Check Duplicate Content

Duplicate content happens when your content (images, videos, text, etc.) appears twice or more times on the same website or on different websites.

Currently, Google’s algorithm is smart enough to detect this. If it detects duplicate content errors (without citing the source), Google might ignore them. Even your website can be penalized if it finds too many identical articles, especially for manipulating search results.

Hence, in this article, we will provide you the great tools to check duplicate content on your website as well as how to protect your original content. If you get ready, let’s start!

  1. What is duplicate content?

It is not difficult to understand what duplicate content means. Your website is always supposed to own original and unique content. In other words, your content only comes with one location on the Internet, which equals a unique website address (URL). 

If the content on your site and other sites has too many similarities, it is called duplicate content. Even if there is the same content on different pages on one website, it might have negative effects on your Google ranking. Duplicate content causes Google and other search engines to encounter difficulties in deciding which content is the most relevant and informative for users.

  1. Why does duplicate content matter?

2.1. For search engines

When receiving too similar content from different places, it is very time-consuming for search engines like Google to determine which version is original or plagiarism. Google’s algorithms do not allow the same content to be ranked in a query, so the majority of duplicate content is often excluded from the rankings.

In addition, if the same content is available at multiple URLs, then each of those URLs can attract different backlinks. That might result in a splitting of link metrics (e.g. URL Rating, anchor text, etc.) between URLs in biased ways.

And most importantly, duplicate content may not be shown at high rankings or may not show up on search results, as Google doesn’t know how to rank between the same duplicate assets. 

2.2. For website owners

Google has stated many times that it does not have a duplicate content penalty. 

If your duplicate content happens by accident such as store item descriptions or printer-friendly versions of content, there is nothing to worry about. However, if it is the result of the deliberate manipulation of search engine indexes or web spam, your site may no longer be available on Google. Even Google can use the Google Sandbox filter to put some restrictions on rankings for your website. A terrible result, right?

Along with that, your visitors also can get confused when they search for a query and are presented with too much duplicate content. Obviously, your website is failing at bringing meaningful and valuable user experiences to them.

Therefore, be careful and check duplicate content websites regularly. It might be a time bomb that hurt your SEO rankings eventually.

  1. How to protect your content website from stealers?

No one can deny that content thieves are a serious problem for any website owner. As we discussed above, duplicate content will certainly hurt your website. Have you ever been the victim of this issue and wondered whether there are any solutions to protect your original content?

Now, let me show you some tips.

  • Shorten URLs in the RSS feed

RSS is a file format in XML for sharing web content. The RSS format provides and summarizes the website content along with URLs to the full version of the content. When you publish content on your website, after a certain period of time, it will be updated to the RSS Feed. This is a loophole for thieves to take advantage of, they will use automatic software to scan your RSS Feed to get content information about their website and then complete the copy. So after only a few minutes, your post has been stolen.

The easiest way to prevent this issue is to shorten RSS, show only a portion of the content, and put a link back to your site. Even thieves who get information on the RSS feed cannot copy all of your content.

  • Copyright registration and information protection at DMCA

To prevent the theft of website content, you will register with DMCA (Digital Millennium Copyright Act). You will add a piece of code to the web page containing content that needs to be protected by the DMCA.

After that, the DMCA will give you a certificate. If you find that another website has stolen content from your website, you only need to report it to the DMCA. They will be responsible for informing the owner of the website you have reported, or DMCA will notify the service provider (such as OSP / ISP) for action.

  • Solutions after your content had been stolen

When you find out that someone has stolen your website content, keep calm.

You can send an email to the person who stole the content, asking them to remove your content from their website. You let them know that they are in breach of copyright (citing Google terms) and they will be penalized if they don’t take appropriate action.

If the content thief does not respond after 48 hours, DMCA will automatically remove the post on their website.

The Last Words,

We hope that this article has provided helpful and informative knowledge about duplicate content on the website. This SEO factor contributes to how Google and other search engines rank your content, hence, check it regularly. These duplicate content checkers will be the most powerful assistants for you!
