Definition and Purpose of Rel=’Noopener’ and Rel=’Noreferrer

The use of rel=’noopener’ and rel=’noreferrer’ attributes in HTML enhances the security and performance of links.

The rel=’noopener’ attribute prevents the linked page from accessing the window.opener object, thus preventing tabnapping and enhancing security. Additionally, rel=’noopener’ improves the performance of the linked page by eliminating unnecessary overhead.

On the other hand, the rel=’noreferrer’ attribute enhances security and protects user privacy by preventing the referrer information from being sent to the linked page. This attribute is particularly useful in preventing CSRF attacks and reducing data transfer.

Impact of Rel=Noopener on WordPress

Enhancing website security and protecting against cross-site hacking, the rel=’noopener’ attribute has a significant impact on WordPress.

By implementing rel=’noopener’ in WordPress, external links are secured against tabnapping attacks. This attribute prevents the linked page from accessing the window.opener object, ensuring that no malicious code can change the original page.

The benefits of rel=’noopener’ in WordPress include enhanced security and improved performance, as it eliminates unnecessary overhead.

While there are alternatives to rel=’noopener’ such as rel=’noreferrer’, rel=’noopener’ remains the preferred option for securing external links in WordPress.

It is important to note that rel=’noopener’ does not impact SEO rankings or overall WordPress performance.

Contrasting Rel=Noopener and Rel=Nofollow

One key difference between rel=noopener and rel=nofollow is their impact on website security and SEO rankings. While both attributes serve important purposes, they address different aspects of website optimization.

Here are three important points to consider when contrasting rel=noopener and rel=nofollow:

  1. Website Security: rel=noopener is crucial for protecting against cross-site hacking and maintaining the integrity of your WordPress site. It prevents malicious code from accessing the window.opener object and making unauthorized changes. On the other hand, rel=nofollow does not directly contribute to website security, as it primarily focuses on controlling the flow of SEO link juice.
  2. SEO Implications: rel=nofollow plays a significant role in SEO rankings by instructing search engines not to pass link authority to the linked website. This can be useful when you want to prevent certain links from influencing search engine rankings. However, rel=noopener does not impact SEO rankings directly, as it primarily addresses security concerns.
  3. User Privacy in Affiliate Marketing: While rel=nofollow and rel=noopener are important in their own right, the attribute rel=noreferrer is crucial for protecting user privacy in affiliate marketing. It prevents the referrer information from being passed to the linked page, ensuring that user data remains private. Affiliate marketers often use link cloaking plugins to redirect users through their own website, further safeguarding user privacy.

Difference Between Rel=Noopener and Rel=Nofollow

When comparing the attributes rel=noopener and rel=nofollow, it is important to understand their distinct roles in website security and SEO optimization.

Rel=noopener is primarily focused on enhancing website security by preventing cross-site hacking. It ensures that the linked page cannot access the window.opener object, protecting against tabnapping and malicious code.

On the other hand, rel=nofollow is primarily used to prevent passing SEO link juice to the linked website. It tells search engines not to follow the link and not to consider it for ranking purposes.

While rel=noopener is crucial for website security, rel=nofollow is more focused on SEO implications. In WordPress, adding rel=nofollow to external links usually requires the use of a plugin, but there are ways to do it manually.

It is also worth noting that rel=noreferrer, which prevents referrer information from being sent to the linked page, has its own impact on user experience and website performance.

Impact of Rel=Noreferrer on Affiliate Links in WordPress

Rel=noreferrer has no impact on affiliate links in WordPress. When it comes to preventing referrer leakage and ensuring user privacy, implementing rel=noreferrer effectively is crucial. Here are three reasons why rel=noreferrer does not affect affiliate links in WordPress:

  1. Preventing referrer leakage: Rel=noreferrer prevents the referrer information from being passed to the linked page. This is important for affiliate marketers who want to keep their referral sources private.
  2. Benefits of link cloaking: Many affiliate marketers use link cloaking plugins to redirect users through their own website. Link cloaking ensures that the clicked affiliate link appears as the website’s URL, providing a more professional and trustworthy appearance.
  3. Impact on affiliate marketing: Rel=noreferrer does not impact the functionality or effectiveness of affiliate links in WordPress. It solely focuses on enhancing user privacy and preventing referrer leakage, which are important considerations for both affiliate marketers and their audience.

Disabling Rel=Noopener in WordPress

To disable the rel=noopener attribute in WordPress, it is necessary to take specific steps to ensure website security and prevent any potential cross-site hacking. However, it is important to consider the security implications before disabling rel=noopener.

This attribute serves as a safeguard against malicious code altering the original page and is considered a best practice for website security. Disabling rel=noopener may expose the website to potential security vulnerabilities.

Alternatively, if disabling rel=noopener is still desired, there are alternatives to consider, such as using rel=noreferrer. However, it is crucial to understand the impact on user experience when implementing these changes.

It is recommended to consult with a WordPress developer or security expert to determine the best course of action.

Removing Rel=Noopener From New Links

To remove the rel=noopener attribute from new links in WordPress, it is necessary to follow specific steps to ensure website security and prevent potential cross-site hacking.

Here are three steps to remove rel=noopener from new links:

  1. Manually editing:
    To remove rel=noopener from new links, you need to edit the HTML of the link manually. This can be done by accessing the code editor or HTML editor in your WordPress dashboard.
  2. Security measures:
    While removing rel=noopener, it is important to ensure that proper security measures are in place. This includes regularly updating WordPress, using strong passwords, and installing security plugins to protect your website from potential vulnerabilities.
  3. Link optimization:
    After removing rel=noopener, it is a good practice to optimize your links for better usability and SEO. This can involve adding relevant keywords, using descriptive anchor text, and ensuring that the links are relevant and valuable to your audience.

While the block editor in WordPress may automatically add rel=noopener to new links, there are alternative block editor plugins available that allow you to customize link attributes and remove rel=noopener if desired.

Manually Editing Old Links

When manually editing old links in WordPress, it is necessary to implement the necessary changes to ensure website security and prevent potential cross-site hacking. Link security is crucial in maintaining the integrity of a website and protecting user information.

By updating old links with the rel=’noopener’ attribute, potential risks such as malicious code injection can be mitigated. This not only enhances website security but also improves the overall user experience by providing a safe browsing environment.

Additionally, updating old links with rel=’noopener’ attribute can have SEO implications, as search engines prioritize websites with enhanced security measures. Therefore, it is essential to prioritize the manual editing of old links to maintain link security, improve user experience, and positively impact SEO rankings.


In conclusion, the rel=’noopener’ attribute in WordPress enhances website security by preventing malicious code and tabnapping through links. It also improves the performance of the linked page by eliminating unnecessary overhead.

It is important to distinguish between rel=’noopener’ and rel=’nofollow’, as they serve different purposes in terms of preventing cross-site hacking and passing SEO link juice.

The rel=’noreferrer’ attribute further enhances security and privacy by preventing referrer information from being sent to the linked page.

Disabling rel=’noopener’ can be done manually in WordPress for both new and old links.
