Why Some Backlinks Have No Follow and What It Means for SEO 2025 Complete Guide

If you’ve ever analyzed your backlink profile, you might ask: why some backlinks have no follow? A nofollow backlink includes a special HTML tag that instructs search engines not to pass on ranking authority or “link juice” to the destination page. Unlike dofollow links which directly influence search rankings, webmasters strategically use the nofollow attribute for several key reasons: to prevent spam in blog comments, identify paid or sponsored content, manage user-generated posts, and ultimately protect their site’s SEO integrity and PageRank. While they don’t provide a direct ranking boost, nofollow links are a critical component of a healthy and natural-looking link profile.

What Is a “Nofollow” Backlink?

A “nofollow” backlink is a hyperlink with a special HTML tag. This tag tells search engines not to give ranking credit to the linked page. You can see this in the code as rel=”nofollow”. The tag shows the website does not support the other site or want to change its search ranking.

• A nofollow is a value added to the rel attribute in HTML.
• It tells search engines not to let the link affect the target’s ranking.
• Nofollow is an HTML attribute (rel=”nofollow”) that stops SEO value from passing through the link.

You might wonder why some backlinks have no follow. The reason is that websites want to protect their reputation and search rankings. Nofollow links help you choose which sites get your authority.

What is the Difference Between Do Follow Backlinks And No Follow Backlinks?

Why Do Websites Implement “Nofollow” Links?

Websites use nofollow links for many important reasons. You can find these links on blogs, forums, social media, and news sites. The main goal is to control authority and stop misuse.

• You can stop spam and bad links from hurting your site.
• You can show which links are paid so search engines know they are not natural.
• You can handle user-made or untrusted content without risking your reputation.
• You can keep your own authority by choosing which sites get credit.

If you want to know why some backlinks have no follow, look at these main reasons.

Preventing Spam and Unwanted Links

Spam is a big problem for many websites. You see spam in blog comments, forums, and user profiles. Nofollow links help stop spammers from getting ranking benefits. Sites like Wikipedia and WordPress use nofollow to stop comment spam from ranking in search results. Nofollow links do not block spam, but they stop people from tricking search engines with bad links.

Tip: If you remove the nofollow tag, you show you trust the link. Most site owners use nofollow to keep their links safe.

Sponsored and Paid Content

Paid links and sponsored posts are common online. You need to mark these links so search engines know they are business deals. Google says you should use rel=”nofollow” or rel=”sponsored” for paid links. This helps search engines sort links and keep things fair.

Evidence	Description
rel=”sponsored”	Use for paid links to show they are part of a paid agreement.
rel=”nofollow”	Prevents passing ranking credit to the linked page.
Proper attributes	Using these tags correctly helps search engines sort links effectively.

If you run ads or sponsored posts, you must use these tags to follow the rules.

User-Generated or Untrusted Content

Many websites let users post comments, reviews, or forum threads. You cannot always trust these links. Nofollow helps you avoid giving authority to sites you do not control. Google says to use rel=”nofollow” or rel=”ugc” for user-made content. This keeps your site safe and stops bad links from hurting your reputation.

Protecting Their Own Authority

You work hard to build your website’s authority. Nofollow links act like a shield. They stop spammy or unrelated links from hurting your credibility. SEO experts say nofollow links help protect your domain authority by stopping bad links from lowering your site’s rank. These links do not add to your backlink profile, so you keep control over your reputation.

Aspect	Dofollow Backlinks	Nofollow Backlinks
Definition	Standard links that pass link equity to the linked site.	Links that signal search engines not to pass link equity.
Impact on SEO	Directly influences rankings by passing authority.	Does not directly affect rankings but can drive traffic.
How Search Engines Treat	Followed by search engines, transferring ranking signals.	Not followed for ranking, but may still be crawled for context.

You need to know the difference between dofollow and nofollow links. Dofollow links pass authority and help with rankings. Nofollow links do not pass authority, but they can still bring traffic and brand awareness. Since Google’s 2019 update, nofollow links are hints. Search engines may pass value if the link is relevant and fits the context.

How do “Nofollow” Links Affect SEO?

Types of “Nofollow” Tags: More Than Just “Nofollow”

There are different nofollow tags in SEO today. Each tag has its own job. These tags help you control your site’s links.

• rel=”nofollow” tells search engines not to give ranking power to the link.
• rel=”sponsored” marks links that are paid or sponsored. This keeps things clear and stops ranking power from passing.
• rel=”ugc” is for user-made content like comments or forum posts. It helps stop spam and keeps your site safe.

These tags let you choose which links to support. You use them to keep your site strong and avoid giving value to risky sites.

Real-World Examples of “Nofollow” Links in Action

Many big websites use nofollow links for different reasons. For example:

• Wikipedia puts nofollow on all outside links in user content. This stops spam.
• News sites like Daily Mail and Yahoo use nofollow links in campaigns. The “Your Face as an Alcoholic” campaign got over 900 stories. “Hotel Hygiene Exposed” had more than 23,000 social shares. These started with nofollow links but still got lots of attention and brand growth.

Direct vs. Indirect Effects

Traffic and Brand Benefits
