A nofollow link is a hyperlink that contains the rel="nofollow" attribute in its HTML. This nofollow tag tells search engines not to follow the link or pass link equity (PageRank) through it. Understanding when and how to use this attribute is crucial for any website's SEO success, especially for e-commerce sites with complex internal linking structures.
Why the Nofollow Attribute Exists
The rel nofollow attribute was originally introduced by Google in 2005 to combat comment spam. Today, it serves as a broader signal that helps webmasters control how link equity flows through their site. For e-commerce sites, the nofollow tag is a powerful tool for shaping internal linking architecture.
- Prevents link equity from flowing to low-value pages
- Controls PageRank distribution across your site
- Helps search engines understand page importance hierarchy
- Marks paid, sponsored, and user-generated links appropriately

Nofollow links don't pass PageRank, allowing you to concentrate link equity on your most important pages.
How Search Engines Treat Nofollow
Google treats the nofollow attribute as a "hint." Search engines still crawl these links but don't use them as direct ranking signals.
User Experience
No follow links function normally for users. Visitors can click and navigate them just like any other link on the page.

Common Use Cases for Nofollow
Login and Account Pages
Add rel nofollow to links pointing to login, registration, and account management pages to prevent search engines from indexing private areas.
Shopping Cart and Checkout
Use the nofollow tag on cart and checkout links to keep PageRank focused on product discovery and category pages.
Paid and Affiliate Links
Google requires that paid or affiliate links carry rel="sponsored" or rel="nofollow" to avoid manual penalties for selling links.
User-Generated Content
Apply nofollow (or rel="ugc") to links in comments, forum posts, and reviews where you cannot vouch for the destination.
Filter and Sort Parameters
Apply nofollow to heavily filtered product listings to avoid diluting link equity across numerous parameter combinations.

Nofollow vs. Sponsored vs. UGC: Which Rel Attribute to Use
In 2019, Google introduced two additional link attributes alongside the original nofollow: rel="sponsored" and rel="ugc". Understanding the differences helps you apply the right no follow tag for each scenario.
rel="nofollow"
The general-purpose nofollow attribute. Use it when you don't want to endorse a linked page or pass PageRank. This is the original no follow tag and remains the catch-all option.
Best for: Internal low-value pages, untrusted links
rel="sponsored"
Use this for links that were created as part of advertisements, sponsorships, or other compensation agreements. Google specifically requests this attribute for paid links.
Best for: Paid placements, affiliate links, ads
rel="ugc"
Stands for "user-generated content." Apply it to links within comments, forum posts, and other content created by your site's users that you haven't individually vetted.
Best for: Comments, forums, user reviews

Nofollow links don't directly pass PageRank, but they can still benefit SEO indirectly by driving referral traffic, increasing brand visibility, and contributing to a natural-looking link profile.

Are nofollow links good for SEO?
Nofollow links are good for maintaining a healthy, natural backlink profile and can drive valuable referral traffic to your site.
