What Is No opener-referrer and Why It Matters for SEO and Website Security

This paper discusses minor but crucial aspects of working on a website or its improvement. Two unimportant properties – ‘none’ and ‘no-referrer’ and the other four- are vital while controlling the external links’ behavior. Familiarity with and correctly utilizing these attributes enhance your site’s security and search engine results. In this article, the author defines what no opener and no-referrer mean, why they are helpful, and how they should be used.

Understanding no opener-referrer

No opener and referrer are attributes linked to the rel attribute of an HTML tag. This attribute informs browsers how links should be processed if users click them simultaneously.

• No opener dimension This value prevents the new page opened by a link from being controlled by the referring window via JavaScript. A linked page can run a script to change the original page or collect valuable data, such as a password, if no opener exists.
• No-referrer: This attribute enables you to stop the browser from sending HTTP referer information to the connected Web site. In other words, the destination page cannot identify the specific page that sent traffic their way.

These attributes help improve security and privacy. When combined, they can reduce some of the present security risks.

The Security Risks of not using no opener with no-referrer

If you fail to address link management, you may find your website severely attacked by other websites. One common issue arises from a vulnerability called window .opener exploitation:

• Window. Opener Vulnerability: Whenever you open another website on a new tab and then use the target=”_blank” attribute, the new tab is granted access to the window.opener property. This makes it possible for the external site to run JavaScript and, in the process, alter your original site.
• Phishing and Hijacking Risks: A malicious website can be used as a window opener, and the content of the original website can be changed to that of another phishing website, requiring users to input their sensitive credentials.

Adding rel=’noopener‘ turned off this connection to avoid suspecting such manipulations with your site.

The Privacy Aspect: usingreferrerr

The referrer attribute prevents copying the URL from the last website visited to the destination site. This adds to the user’s privacy and shields referral references from exposure to other domains outside the application. It may also be helpful in selected SEO techniques where one does not want to pass link juice or refer data to another website.

The SEO Implications of the no opener no-referrer

When it comes to SEO, using opener no-referrer has mixed implications:

• No Direct Impact on Rankings: Nothing putting these attributes to your website affects your search engine ranking. Search engines that use Google (such as Google itself) will not penalize a site for using these attributes, nor will they help the site’s rankings by following them.
• Link Juice Flow: The referrer attribute may restrict referral data, but that doesn’t mean it forces SEO away from link equity (link juice). Not all SEO experts, however, suggest that nofollow or no-referrer limits the SEO benefit of external links.
• User Experience and Trust Signals: Browsing security can have indirect SEO advantages. More engaging sites prioritize user security and privacy and build user trust.

How to use Noopener Noreferrerr

To decide to use no opener or no-referrer is easy and is as follows. Here is a sample HTML code showing how to apply these attributes:

<a href=”https://example.com” target=”_blank” rel=”no openopenererrerr”>Visit Example</a>

In this example:

• target="_blank" Opens the link in a new tab.
• rel="noopener noreferrer" ensures that your site remains secure by turning off the window.opener property and withholding referrer information.

Recommendations on the no-opener no-referrer

1. Always Use rel= “no opener-referrer” with target=”_blank”: Adding these attributes should be standard practice when creating links that open in a new tab.
2. Use rel=”nofollow” to prevent a passing link equity to specific sites, and use the appropriate referrer settings when applicable.
3. Review External Links Periodically: Regularly check your site’s external links to ensure they are secure and follow best practices for user privacy.

Tools to Help Implement reall Attributes

With many external links to your website, adding No opener-referrer can be time-consuming. Several tools and plugins can help streamline this process:

• WordPress Plugins: For example, plugins like “External Links” or “WP External Links” will automatically add no opener or no reference for links on your site.
• SEO Audit Tools: Tools like Ahrefs, Moz, or SEMrush can help you better understand how your site is ‘linked’ and recommend areas for improvement in security and privacy.

Conclusion

It can also benefit most websites by teaching them how to properly implement or change the no-referrer or open policy, which does not automatically send referer headers in subsequent links. This can boost security and privacy without negatively affecting SEO. Most of these attributes do not directly affect search engine rankings. Still, they protect your website and visitors. Adopting and using them shows that you have user safety and live in a safe city, which creates trust and, in turn, positive engagement.
