Are nofollow links really ignored by Google?

What exactly is Google's link graph?

The link graph represents the interconnected structure of the web as perceived by Google. Each page is a node, each link an edge that transmits PageRank and authority.

When Google states that a link is not in this graph, it means it is not followed during authority calculations. The link technically exists, but it is invisible to the ranking algorithm based on link popularity.

Why did Google introduce the nofollow attribute?

The rel="nofollow" attribute was created to combat comment spam and link abuse. The initial goal? To allow webmasters to publish user-generated content without risking the transfer of authority to unreliable sites.

Google also wanted to prevent sites from selling PageRank through undisclosed sponsored links. Nofollow was meant to neutralize these practices by making such links invisible to the engine.

What does "irrelevant" mean for SEO?

A nofollow link brings no link juice. It does not contribute to the ranking of the target page in search results. It's as if this link does not exist from the PageRank perspective.

However, this does not mean the link is completely useless. It can generate direct traffic, boost brand awareness, or even help Google discover new pages (though this is no longer guaranteed since updates to the directive).

• Nofollow links do not transmit any PageRank according to this official statement.
• They do not count in the link graph used for ranking.
• Their main utility remains direct traffic and potential content discovery.
• Google can still crawl the target page, but there's no guarantee.
• The nofollow attribute should be used for sponsored, UGC, or untrustworthy links.

Is this statement consistent with field observations?

Google's position is clear on paper, but field experience tells a more nuanced story. Many SEOs observe that sites with a predominantly nofollow link profile (social media, forums) can still rank well.

The question is whether these results are due to other signals (brand mentions, traffic, engagement) or if Google sometimes uses nofollow links as contextual clues without formally incorporating them into the graph. [To be verified]: no public study has conclusively demonstrated the total lack of indirect impact.

What nuances should be added to this rule?

Since the update of link attributes (nofollow, sponsored, ugc), Google now treats nofollow as a hint rather than an absolute directive. This means Google can choose to follow a nofollow link in certain contexts.

This evolution partially contradicts the initial statement. If Google completely ignores these links in the graph, why treat them as hints? The likely reality: nofollow links can aid in content discovery and contextual understanding, without directly transmitting PageRank.

In what cases does this rule not fully apply?

Nofollow internal links are a common anomaly. Some CMS automatically add nofollow to navigation or pagination links. Google may ignore them, wasting crawl budget and diluting site architecture.

Another edge case: nofollow links from authority sites (Wikipedia, .gov, major media). Even without PageRank transmission, these links send a signal of contextual legitimacy that Google can exploit in other ways. A nofollow link from The New York Times remains more valuable than a dofollow link from a spam blog.

What should you actually do with nofollow links?

Focus your link acquisition efforts on high-quality dofollow backlinks. These are the ones that transmit authority and improve your rankings. Nofollow links can complement your natural link profile, but should not be your priority.

Use the nofollow attribute (or better: sponsored for paid links, ugc for user-generated content) on all outgoing links that you do not fully endorse. This protects your site from link pollution and adheres to Google’s guidelines.

What mistakes to avoid with the nofollow attribute?

The most common mistake? Putting nofollow on internal links to your own important pages. Some webmasters think they are "saving" PageRank, but they mainly prevent its strategic distribution to pages they want to promote.

Another trap: totally neglecting nofollow links in your strategy. Even without PageRank transmission, a nofollow link from a high-traffic site can generate qualified visits and enhance your visibility. SEO is not just about PageRank.

How can I audit the use of nofollow on my site?

Use a crawler like Screaming Frog or Sitebulb to identify all internal links marked as nofollow. Ensure that only non-strategic links (legal mentions, TOS, affiliate links) carry this attribute.

Also examine your outgoing links. Any commercial, sponsored, or unverified content link should be tagged (sponsored or nofollow). Conversely, an editorial link to a quality resource can safely remain dofollow.

• Prioritize acquiring dofollow backlinks in your link-building strategy.
• NEVER set your strategic internal links (navigation, thematic linking) to nofollow.
• Use rel="sponsored" for all commercial links or paid partnerships.
• Apply rel="ugc" to links in comments, forums, or user content.
• Regularly audit your internal links to detect accidental nofollows.
• Accept nofollow links from authority sites (traffic, reputation, context).
