The digital landscape thrives on connections – links between websites are fundamental to how search engines understand and rank content. However, not all links are created equal. While some links signal trust and authority, others can be detrimental to your search engine optimization (SEO) efforts. This is where the nofollow attribute comes into play. In the context of WordPress, understanding and correctly implementing the nofollow attribute is crucial for maintaining a healthy website, avoiding penalties, and strategically managing link equity. This guide will delve into the intricacies of the nofollow attribute, explaining its purpose, benefits, implementation methods within WordPress, and best practices for maximizing its effectiveness.
The Foundation: What is the Nofollow Attribute?
At its core, rel="nofollow" is an HTML attribute used within the anchor tag (<a>) of a hyperlink. It serves as a directive to search engine crawlers, specifically instructing them not to follow that particular link. This means that the link will not contribute to the ranking of the linked page, and no “link juice” – a metaphorical term for the authority and equity passed from one page to another through links – will be transferred. Introduced by Google in 2005, the primary intention behind nofollow was to combat comment spam. Spammers were exploiting the ability to link back to their websites from blog comments, attempting to manipulate search rankings.
The nofollow attribute doesn’t prevent users from clicking the link; it simply tells search engines to disregard it for ranking purposes. It’s important to understand that nofollow doesn’t inherently make a link “bad.” It’s a tool for managing the flow of link equity and signaling trust (or lack thereof) to search engines. The attribute is added to a link like this: <a href="http://example.com/article" rel="nofollow">Article Example</a>.
Why Use Nofollow Links? A Multifaceted Approach
The applications of nofollow extend far beyond simply combating comment spam. Several scenarios warrant the use of this attribute, each contributing to a more robust and trustworthy online presence.
- Preventing Spam Comments: As originally intended,
nofollowremains a vital defense against comment spam. By applyingnofollowto all external links within comments, you discourage spammers, as their links won’t provide any SEO benefit. WordPress, thankfully, automatically adds thenofollowattribute to all links in comments by default, simplifying this process. - Managing Internal Linking: While counterintuitive, strategically using
nofollowon internal links can be beneficial. For example, if you have a large website with numerous internal links, you might usenofollowon less important links to concentrate link equity on your core, high-value pages. - Affiliate Links & Sponsored Content: Transparency is paramount in the world of SEO. When you include affiliate links or sponsored content on your website, you must use the
nofollowattribute. This signals to search engines that you are receiving compensation for the link, maintaining compliance with Google’s guidelines and avoiding potential penalties. - Untrusted Content: If you link to a website you don’t fully trust, or one with questionable content, using
nofollowprotects your website’s reputation. You’re essentially saying, “I’m linking to this page, but I don’t necessarily endorse its content.” - Links to Login/Registration Pages: Links leading to login or registration pages don’t need to be indexed by search engines. Applying
nofollowensures they aren’t crawled unnecessarily.
Implementing Nofollow Links in WordPress: Two Primary Methods
WordPress offers two main approaches to adding the nofollow attribute to your links: manual implementation and utilizing plugins.
1. Manual Implementation with the Gutenberg Editor
For infrequent use, manually adding nofollow is a straightforward process, especially with the Gutenberg block editor.
- Highlight the text you want to turn into a link.
- Click the link icon in the Gutenberg toolbar.
- Enter the URL in the provided field.
- Click the small gear icon next to the URL field to access "Advanced Settings".
- In the "Rel Attribute" field, type
nofollow. - Save or publish your post/page.
This method provides granular control but can be time-consuming if you need to add nofollow to numerous links.
2. Utilizing WordPress Plugins
For more extensive or automated control, WordPress plugins offer a convenient solution. Several plugins are available, each with its own features and capabilities.
- WP External Links: This popular plugin allows you to automatically add
nofollowto all external links on your website. You can configure it to open external links in a new tab as well. After activation, navigate to "Settings > External Links" and set the "Set follow or nofollow" dropdown to "nofollow." - Ultimate List of Dofollow & Nofollow Plugins: This resource provides a curated list of plugins offering various functionalities related to

While plugins offer convenience, be mindful of plugin bloat and choose a well-maintained, reputable plugin.
A Comparative Look at Implementation Methods
| Feature | Manual Implementation | Plugin (e.g., WP External Links) |
|---|---|---|
| Control | Highest - precise control over each link | Moderate - configuration options, but less granular |
| Time Efficiency | Lowest - requires manual editing for each link | Highest - automated application to all/selected links |
| Complexity | Lowest - simple HTML editing | Moderate - plugin installation and configuration |
| Resource Usage | Minimal - no additional server load | Moderate - plugin adds to server load |
| Best For | Infrequent use, specific links | Large-scale application, automated control |
Avoiding Common Pitfalls and Best Practices
While the nofollow attribute is a powerful tool, it’s essential to use it judiciously. Here are some key considerations:
- Don't Overuse: Automatically
nofollow-ing all external links is generally discouraged. It prevents you from passing authority to credible websites, which can be a positive SEO signal. - Manual Control is Preferred: Whenever possible, manually control your
nofollowlinks to ensure you’re strategically managing link equity. - Regularly Review: Periodically review your links to ensure the
nofollowattribute is applied correctly and remains relevant. - Understand the Tradeoffs: Be aware of the implications of using
nofollow. While it protects your website, it also means you’re not contributing to the ranking of the linked page. - Check Your Work: Use browser developer tools (right-click > Inspect) to verify that the
nofollowattribute has been correctly applied to your links.
Checking for Nofollow Links
You can easily verify if a link has the nofollow attribute using your browser's developer tools. Right-click on the link and select "Inspect" or "Inspect Element." This will open the browser's developer console, where you can examine the HTML code of the link. Look for the rel="nofollow" attribute within the <a> tag. If it's present, the link is nofollow.
Key Terminology
- Link Juice: A metaphorical term representing the authority and equity passed from one page to another through links.
- Dofollow Link: A link that passes link juice and contributes to the ranking of the linked page.
- Anchor Text: The visible, clickable text of a hyperlink.
- HTML Attribute: A modifier that provides additional information about an HTML element.
- SEO (Search Engine Optimization): The practice of improving a website's ranking in search engine results pages.
The Bottom Line
The nofollow attribute is an indispensable tool in the WordPress SEO arsenal. By understanding its purpose, applications, and implementation methods, you can effectively manage your website’s link profile, protect your reputation, and maintain a healthy online presence. While automated solutions offer convenience, a strategic, manual approach to nofollow implementation remains the most effective way to maximize its benefits and ensure long-term SEO success. Mastering this attribute isn’t just about avoiding penalties; it’s about taking control of your website’s link equity and building a more trustworthy and authoritative online presence.
