Master the strategic use of nofollow links to help guide link equity distribution, optimize internal linking structure, and support your e-commerce site's SEO performance as part of a broader content strategy roadmap.
RVshareKleinanzeigenWhat Is a Nofollow Link?
A nofollow link is a hyperlink that uses the rel="nofollow" attribute to tell search engines not to pass link equity (PageRank) to the destination page. The nofollow tag was originally introduced by Google in 2005 to combat comment spam, and understanding tools like the Google Search Console API can help you see how it has since become an essential tool for managing how authority flows across any website.

How the Rel Nofollow Attribute Works
When a search engine crawler encounters an a href element with rel="nofollow", it treats the link as a hint not to count that link as an editorial vote for the target page. This means no follow links do not directly contribute to the linked page's rankings.
- Prevents link equity from flowing to low-value pages
- Controls PageRank distribution across your site
- Can provide a signal about page importance hierarchy, though Google treats nofollow as a hint
- Complies with Google guidelines for paid and affiliate links
HTML Nofollow Link Code Examples
Impact on PageRank Flow
Since 2019, Google treats nofollow as a hint rather than a directive, so while nofollow links may discourage PageRank from passing, the effect is not guaranteed.
Google Treats Nofollow as a Hint
Since 2019, Google treats the no follow attribute as a hint rather than a directive. Crawlers may still follow and index nofollowed URLs.
User Experience
Nofollow links function normally for users who click them while helping you optimize your site's SEO architecture behind the scenes.
When to Use Nofollow Links
Knowing which types of links should be nofollow is critical for SEO. Here are the most common scenarios where you should add the nofollow tag to your HTML links.
Types of Links That Should Be Nofollow
Paid and Sponsored Links
Google Search Central guidelines state that paid links must use rel="sponsored" or rel="nofollow" to avoid penalties. This includes banner ads, sponsored content, and any link exchanged for compensation.
Nofollow Affiliate Links
Affiliate links should use rel="sponsored nofollow" per Google Search Central affiliate links guidance. This applies to Amazon Associates, ShareASale, and any commission-based outbound link, including iframe affiliate links.
User-Generated Content
Comments, forum posts, and community-submitted links should use rel="ugc nofollow" since you cannot vouch for content created by third parties.
Login, Cart, and Account Pages
Adding nofollow to links pointing to login, registration, and account management pages can discourage search engines from following those links, though for reliable exclusion from indexing, use robots.txt or noindex directives.
Nofollow Decision Framework
Nofollow Internal Links: Should You Use Them?
Using nofollow on internal links is not a reliable way to sculpt PageRank, since Google treats it as a hint and the PageRank assigned to nofollowed links may simply evaporate rather than redistribute. The risk comes from over-applying nofollow and accidentally reducing crawl efficiency or discoverability for important category or product pages. The key is to use nofollow internal links selectively, audit regularly, and rely on site architecture as the primary tool for prioritizing pages.
Keep as Follow (Internal)
- Main category to subcategory navigation
- Featured product links on homepage
- Category page to top products
- Product to related category links
Consider Nofollow (Internal)
- Faceted navigation and filter URLs
- Out-of-stock or discontinued items
- Login, cart, and checkout pages
- Deep pagination (page 4+)
How to Create a Nofollow Link in HTML
Adding a nofollow link in HTML is straightforward. You simply add the rel="nofollow" attribute inside the anchor (<a>) tag. Below are the most common nofollow code patterns you'll need.

Nofollow and Internal Linking Optimization
An intentional internal linking structure that thoughtfully applies follow and nofollow attributes can help signal which pages you consider most important, though since Google treats nofollow as a hint, results may vary. Similar AI's Linking Agent coordinates five specialized sub-agents to deploy data-driven internal linking strategies using GSC, SERP, crawl, and revenue data, including boosting high-value pages and creating related, cluster, and popular links.
Strategic Link Placement
Position your most important links prominently in navigation, category hierarchies, and featured content areas to help maximize PageRank flow to key pages.
- • Main navigation menus
- • Breadcrumb navigation
- • Featured product sections
- • Related product recommendations
Managing Large Product Catalogs
For large catalogs with thousands of product variations, use canonical tags and parameter handling in Google Search Console as the primary tools, and consider nofollow as a supplementary signal to help manage crawl budget. Ensure your best-selling items are prominently linked with follow links.
- • Concentrate follow links on top performers
- • Limit deep pagination crawling
- • Focus on conversion-optimized pages
- • Prioritize category landing pages
Navigation Structure Impact
Your site's navigation structure is one of many factors that influences how PageRank flows. While nofollow can provide a supplementary signal, clear site architecture and prominent follow links are the most reliable ways to help search engines discover and prioritize your most valuable content.
- • Clear category hierarchies
- • Logical product groupings
- • Streamlined user journeys
- • Crawl-friendly architecture

Nofollow vs Sponsored vs UGC: Which Rel Attribute to Use
Google now supports three distinct link attributes for controlling how link equity flows. Understanding the difference helps you stay compliant with Google Search Central's guidelines for paid links and affiliate content.
rel="nofollow"
The general-purpose no follow attribute. Use it when you don't want to pass link equity and no more specific attribute applies. Works on any HTML anchor tag.
Best for: general untrusted links, login pages, filter URLs
rel="sponsored"
Specifically for paid placements and nofollow affiliate links. Per Google Search Central guidelines, use this for any link that was created as part of an advertisement, sponsorship, or affiliate agreement.
Best for: paid links, affiliate links, sponsored content
rel="ugc"
Designed for user-generated content. Apply this to links within comments, forum posts, and other community-contributed content where you cannot fully vouch for the linked resource.
Best for: comments, forums, reviews, community links
Nofollow Best Practices for E-Commerce
Strategic nofollow implementation is one tool among several, including canonical tags, robots.txt, and thoughtful site architecture, that can help e-commerce sites manage crawl budget, prioritize important product pages, and address large-scale internal linking challenges.
User Account Pages
Adding nofollow to links pointing to login, registration, and account management pages can discourage crawlers from following those links. However, for reliable prevention of indexing, pair this with noindex meta tags or robots.txt rules.
Shopping Cart and Checkout
Consider using nofollow on cart and checkout links as a supplementary signal to help manage crawl budget. Note that Google treats nofollow as a hint, so for reliable results, also use noindex on transactional pages that shouldn't appear in search results.
Filtered Product Pages
Nofollow can be applied to heavily filtered product listings as one approach to managing crawl budget across numerous parameter combinations, though canonical tags and URL parameter handling in Google Search Console are typically more effective solutions.
In e-commerce, how does nofollow help?
In e-commerce, using nofollow can be part of a broader strategy to signal which pages you consider lower priority, such as login pages, filters, or affiliate URLs. However, since Google treats nofollow as a hint (not a directive), it should be combined with other techniques like canonical tags and proper site architecture for reliable results.
Linking low-value pages
Linking to low-value pages such as terms of service, privacy policies, and cookie consent pages can use crawl budget on large sites. While nofollow may discourage crawlers from following these links, the PageRank assigned to nofollowed links may simply evaporate rather than redistribute to other pages.
How Similar AI Helps
The Linking Agent can flag outbound links in product pages so your team can apply the correct rel attribute before publishing. This ensures compliance with Google's guidelines for sponsored and affiliate links.
Balancing Follow and Nofollow Links
A thoughtful mix of follow and nofollow links can help signal your page priorities to search engines, though since Google treats nofollow as a hint, the impact on PageRank distribution is not guaranteed. Focus on strong site architecture as the primary way to channel authority to your most important pages.
Frequently Asked Questions About Nofollow Links
What is a nofollow link?
A nofollow link is a hyperlink that includes the rel='nofollow' attribute in its HTML code. This attribute signals to search engine crawlers that the linking page does not endorse or vouch for the linked content. Since 2019, Google treats nofollow as a hint rather than a strict directive, meaning it may still choose to follow or index the linked page.
Do nofollow links help SEO?
Nofollow links do not reliably pass PageRank, but they can still benefit SEO indirectly by driving referral traffic, increasing brand visibility, and contributing to a natural-looking backlink profile. Because Google treats nofollow as a hint, some nofollow links may subtly influence crawling and indexing. A healthy mix of followed and nofollowed links is generally considered a sign of an organic link profile.
How do I fix internal nofollow links in WordPress?
In WordPress, internal nofollow links are often added by plugins or themes that apply nofollow attributes globally, including to internal links. You can fix this by reviewing your SEO or link management plugin settings and disabling the nofollow option specifically for internal links. Alternatively, a developer can audit your theme's code to remove any nofollow attributes being added programmatically to internal URLs.
How do I fix nofollow internal links for SEO?
To fix nofollow internal links, start by crawling your site with a tool like Screaming Frog to identify which internal links carry the nofollow attribute. Once identified, remove the rel='nofollow' attribute from those links in your CMS, templates, or plugin settings, since internal links generally should pass equity freely. Reserve nofollow for external links pointing to untrusted, paid, or user-generated content.
How do I nofollow iframe affiliate links?
Iframes load content from a third-party URL, so adding nofollow directly to the iframe element itself does not work the same way as on a standard anchor tag. The most reliable approach is to ensure any affiliate links within the iframe source are nofollowed at the source level, or to use a server-side redirect with a nofollow-tagged anchor link that points to the iframe destination. Consulting the affiliate network's technical documentation is recommended for platform-specific guidance.
