What is External Duplicate Content

Duplicate content refers to blocks of content that are identical or substantially similar across multiple URLs or domains. It can negatively impact search engine optimization (SEO) efforts, leading to reduced visibility and rankings. External duplicate content specifically refers to duplicated content found on external websites or domains other than your own.


In the digital landscape, content is king. Search engines value unique and high-quality content, considering it a vital factor in determining the relevance and authority of a website. However, the issue of duplicate content persists, posing challenges for website owners and SEO professionals alike. In this article, we will delve into the concept of external duplicate content, its impact on SEO, the causes behind it, methods to identify and prevent it, and best practices for maintaining SEO-friendly content.

Understanding Duplicate Content

Duplicate content refers to substantial blocks of content that are present on multiple URLs or domains. Search engines aim to provide the most relevant and diverse results to users, so they generally avoid displaying identical or similar content in their search results. Duplicate content can occur both within a single website (internal duplicate content) and across different websites (external duplicate content).

External Duplicate Content

External duplicate content refers to identical or significantly similar content found on external websites or domains other than your own. It can arise from various sources, such as content scraping, syndication, and improper URL handling. External duplicate content poses a challenge for website owners because search engines may not always attribute the original source of the content accurately.

Impact on SEO

External duplicate content can have a detrimental impact on SEO efforts. Search engines strive to deliver the best user experience by providing unique and valuable content. When multiple websites contain identical or highly similar content, search engines face difficulties in determining the most relevant and authoritative source. As a result, rankings may suffer, and organic traffic could decline.

Causes of External Duplicate Content

Several factors contribute to the presence of external duplicate content. Content scraping and syndication are common sources where websites copy and publish content from other sources without permission or attribution. Additionally, URL parameters and session IDs can generate multiple versions of the same content, leading to duplicate URLs. Canonicalization issues, such as improper implementation of canonical tags, can also result in external duplicate content.

Identifying External Duplicate Content

Identifying external duplicate content is crucial for taking appropriate measures to address the issue. Plagiarism detection tools can help identify copied content across different websites. Manual inspection and analysis are also valuable, involving the comparison of content across multiple domains and searching for similarities.

Preventing External Duplicate Content

Preventing external duplicate content starts with creating unique and valuable content. By providing original information, insights, and perspectives, you reduce the chances of others copying your content. Properly configuring canonical tags is essential to guide search engines in recognizing the preferred version of a page. Effective management of URL structures and parameters is another crucial aspect to avoid generating duplicate URLs.

Dealing with External Duplicate Content

When you encounter instances of external duplicate content, there are several actions you can take. Contacting the website owner and requesting removal or proper attribution of the content is a viable option. Implementing 301 redirects can help consolidate link equity to the original page. The rel=”canonical” tag can be employed to signal the preferred version of a page to search engines.

Handling Duplicate Content Issues

Handling duplicate content issues requires ongoing efforts. It is essential to communicate with search engines through webmaster tools, notifying them of the preferred version of a page. Monitoring and addressing any new instances of duplication that may arise is also crucial to maintain a healthy online presence.

Best Practices for SEO-friendly Content

To create SEO-friendly content, adhere to these best practices. Focus on producing unique and valuable content that serves the needs of your target audience. Incorporate internal linking to enhance navigation and provide search engines with a clear understanding of your site’s structure. Implement structured data to enhance search engine visibility and improve the display of your content in search results.


External duplicate content poses challenges for website owners and SEO professionals. Its presence can lead to negative SEO consequences, including reduced visibility and rankings. By understanding the causes, implementing preventive measures, and following SEO best practices, you can minimize the impact of external duplicate content and maintain a strong online presence.
