How to Manage Duplicate Content Issues in SEO 

Duplicate content doesn’t just happen because of your fault, but externally, too. Learn how you can avoid the penalty. ...

One of the persistent problems that has harmed search engine results page (SERP) rankings of businesses is content duplication. Why? Being punished because of dishonest attempts to manipulate search results. The fact that it happened accidentally won’t matter to the machines. Therefore, you should focus on avoiding SEO-harmful duplicate content on your site. 

Confusing content is bad for SEO. Search engines may be confused about which version of the information to prioritize or even punish your site by demoting it. Because of this, it’s essential to prevent and eliminate duplicates. 

So, let’s dive deep into unraveling the mysteries around duplicate content and how to manage them. 

What is Duplicate Content, And What Are Its Types?

Having content that is duplicated is like having digital twins. It describes sections of text that appear on multiple websites yet have minor variations. This resemblance might exist internally on your website or externally on other websites. 

There are two types of duplicate content. 

  • Internal Duplicate Content occurs when multiple pages within your site have similar or identical content. For instance, Having identical product descriptions appear on different product pages. 
  • External Duplicate Content – We’re referring to information that can be found on your site and elsewhere online. This can happen if someone else uses your work without giving you credit for it. 

SEO Best Practices to Avoid Duplicate Content

1. Canonicalization

Indicating to search engine crawlers which version of a page should be considered the “main” one is what canonical tags are for. By doing so, search engines will know that while you may have multiple pages with comparable content, you only want one of them to be prioritized. 

How do we implement canonical tags correctly? 

  • Find the duplicates that need fixing first. What kind of material is it, exactly? A blog post, maybe? A product page? 
  • You should include a canonical tag in the replica page’s HTML that links to the preferred (original) page. 
  • Always use the same canonical tag when dealing with duplicate content. 
  • Once the canonical tags have been implemented, they should be monitored in Google Search Console regularly to ensure that search engines are using them. 

2. URL Parameters and Pagination

Duplicate content problems caused by URL parameters are common. Go to ‘URL Parameters’ in Google Search Console to control them and tell Google how to handle them. You can tell Google to disregard specific parameters that cause duplicate content, for instance. 

You can prevent search engines from indexing duplicate content by including a robots.txt file that specifies the URLs and parameters that should be ignored. 

To minimize problems with duplication, you should also strive to put more effort into developing original material. 

How Do You Deal With Existing Duplicate Content Issues?

1. With the help of Redirects and 301s

Redirects are your traffic cops in the digital world. They guide users and search engines to the right destination when a page changes or moves. Here’s when and how to use them:

When to Use Redirects:

  • If you rename a page or change its URL, implement a redirect from the old URL to the new one.
  • When you remove a page, create a redirect to a relevant, similar page to prevent users from hitting a dead end.

How to Implement Redirects:

  • 301 Redirect: The 301 redirect is the most popular and is good for search engine optimization. It notifies crawlers that the location of a page has changed permanently. It requires server-side scripting or editing the .htaccess file (on Apache systems). 
  • 302 Redirect: Use this for temporary moves. It informs search engines that a page has temporarily moved. You can implement it in a similar way to the 301 redirect.

2. By Customizing Noindex and Nofollow Tags

Noindex and nofollow tags are like “do not enter” signs for search engines. 

Noindex Tags: Use these when you want to hide a specific page from search engines. Common scenarios include:

  • Duplicate Content: If you have a duplicate page that you don’t want to show up in search results, add a noindex tag to it.
  • Thin Content: For low-quality or thin content pages that you don’t want to impact your site’s overall SEO.

Nofollow Tags: To prevent search engines from following a link, use the nofollow tag. This is useful in scenarios like:

  • User-Generated Content: When you have user-generated content on your site (e.g., comments), insert nofollow links in those areas to prevent potential spam from affecting your site’s SEO.
  • Affiliate Links: If you have affiliate links on your site, adding nofollow tags ensures they don’t pass on SEO value to the linked websites. 

How to implement Noindex and Nofollow tags?

You can add a noindex tag to a page’s HTML in the <head> section. Alternatively, you can use the “noindex” directive in your website’s robots.txt file. To add a nofollow tag to a link, simply insert the attribute rel=”nofollow” within the link’s HTML code. 

3. By Content Scraping and Implementing Copyright Infringement  

Content scraping is like the online version of someone taking credit for your hard work. But if you want to stop it from happening, here is how to do it.

  • Create a robots.txt file to instruct search engines not to crawl specific parts of your site or specific files that contain valuable content.
  • Implement captchas on forms where users can submit content to deter automated scraping. 

Copyright infringement is also a serious matter that can harm your online presence and reputation. Here’s how to address it:

You should be aware that copyright Infringement may lead to:

  • Loss of Control: When others use your content without permission, you lose control over how it’s presented and where it’s published.
  • Negative SEO Impact: Copyright infringement can lead to duplicate content issues, hurting your search engine rankings.

What do you do if someone does copyright infringement on your website? 

  • DMCA Takedown Notices: File a DMCA takedown request with the hosting provider or platform where the infringement occurred if you discover your content has been used without authorization. 
  • Reach Out: Sometimes, a friendly email to the infringing party can resolve the issue. Politely ask them to remove or properly attribute your content.
  • Legal Action: In extreme cases, consult with legal counsel to explore legal actions against copyright infringers.

Monitoring and Regular Maintenance

Regular Audits

Think of regular content audits as routine check-ups for your website’s health. They’re essential for several reasons:

  • Quality Assurance: Audits ensure that your content remains high-quality and aligned with your SEO goals.
  • Detecting New Issues: The internet is a dynamic, ever-shifting environment. Duplicate content concerns can develop whenever new content is added to a website; thus, doing regular audits is essential. 
  • Improving User Experience: By identifying and addressing duplicate content, you provide a smoother and more engaging user experience.

Wondering how often you should conduct content audits, and what tools to use?

Well, quarterly or semi-annual audits are generally sufficient for most websites. However, if your site frequently adds or updates content, more frequent audits may be necessary.

To answer the second query, think about utilizing Screaming Frog, SEMrush, or Ahrefs, all of which are SEO auditing tools. Crawling your website with these tools might help you find duplicate content concerns and gain valuable insights. 

Monitoring Tools for Duplicate Content 

To maintain a vigilant watch over your website’s duplicate content, you’ll need reliable monitoring tools. Here are a few suggestions:

  • Google Search Console: This free tool will give you a treasure trove of information about your website’s performance. It provides alerts and insights into duplicate content issues.
  • Copyscape: As mentioned earlier, Copyscape is a fantastic tool for checking if your content has been duplicated elsewhere on the web.
  • Siteliner: Siteliner not only identifies duplicate content but also helps you track internal link structures and broken links. 

However, quick handling of duplicate content issues requires vigilant monitoring. In addition, you can have notifications sent to you anytime duplicate content problems occur. You may use Google Alerts to keep an eye on how often certain keywords or phrases appear in relation to your content. Google will give you a notification whenever it finds these terms on other websites. There are SEO auditing tools that include notification systems. Set up alerts for when duplicate content is found during regular crawls.


I’m hoping you were able to glean some useful information and tactics for combating duplicate content in SEO from this article. We recommend scheduling regular audits to ensure your SEO initiatives’ long-term success.

Remember that SEO is always changing and that the success of your website will ultimately hinge on how well you handle duplicate material.
