Should you really ignore NoFollow links from negative attacks?

Why does Google differentiate NoFollow links in negative attacks?

The NoFollow was originally designed to block the transmission of PageRank. When a malicious site points thousands of spammy links to your domain with this attribute, no ranking signal passes through. Google simply ignores them in its authority calculations.

John Mueller's statement aims to reassure practitioners who panic at sudden spikes in dubious backlinks. If these links carry the NoFollow attribute, they pose no algorithmic threat. The disavow file becomes unnecessary for this specific category.

What exactly is a link attack?

A negative SEO attack involves artificially creating hundreds or thousands of toxic backlinks pointing to a competitor. The goal? To trigger a Penguin or manual penalty by polluting their link profile. Classic techniques include link farms, networks of hacked sites, or mass spam comments.

Historically, Google has always downplayed the actual impact of these attacks, claiming that its algorithms know how to discern. Yet, many SEOs report sharp drops after waves of spam. The on-the-ground reality does not always match the official narrative.

Is the disavow still useful in other contexts?

Absolutely. The disavow file retains its usefulness for toxic DoFollow links that you cannot manually remove. Typically: old PBN networks, identified link purchases, backlinks from penalized or hacked sites that actually transmit juice.

Google recommends using the disavow only as a last resort, after attempting a manual clean-up. But when faced with hundreds of poor DoFollow referring domains, it's often the only option. NoFollow links escape this logic since they do not count in the PageRank equation.

• NoFollow blocks the transmission of PageRank: no impact on the target site's authority
• 100% NoFollow attacks require no disavow action
• The disavow remains relevant for immutable toxic DoFollow links
• Google claims to automatically handle the majority of negative SEO attempts
• Panic over NoFollow backlink spikes is unfounded from an algorithmic standpoint

Does this statement truly reflect how the algorithm works?

In principle, yes. NoFollow has always been designed to cut off the flow of PageRank. Tests conducted by the SEO community confirm that these links do not directly influence ranking. Mueller's statement is consistent with what we observe in crawling and backlink analysis.

But here's the catch: pure negative attacks using NoFollow are incredibly rare. Attackers are well aware that NoFollow does nothing to harm. They favor mass DoFollow links specifically to trigger algorithmic alerts. This statement thus addresses a theoretical case rather than a real SEO threat in the field.

What nuances should be applied to this rule?

First point: some SEO tools include NoFollow in toxicity metrics. A profile displaying 10,000 NoFollow backlinks from dubious sites may raise concerns for a client or a junior auditor. Even if Google ignores them, the external perception can be problematic. [To verify]: the potential impact on the trust of business partners or investors scrutinizing KPIs.

Second nuance: mixed attacks. A clever competitor may mix 80% NoFollow (for apparent volume) and 20% toxic DoFollow links (for algorithmic impact). In this case, you must address the DoFollow via the disavow. Ignoring everything just because “it’s NoFollow” would be a misjudgment.

In what cases might this rule not be sufficient?

If NoFollow links come from hacked sites displaying illegal content or phishing, your domain may appear on third-party blocklists used by antivirus software or browsers. Google will not penalize you in ranking, but your digital reputation takes a hit. In these extreme situations, a disavow can serve as proof of good faith to authorities or blacklists.

Another scenario: a manual penalty already imposed for link spam. If Google asks you to clean your profile, it's better to disavow all suspicious links, including NoFollow, to demonstrate your seriousness in reconsideration. The manual spam team does not always apply strict algorithmic logic.

What should you do in response to a NoFollow attack?

Start by checking the link attributes in your favorite backlink tool (Ahrefs, Majestic, Semrush). Filter by NoFollow and DoFollow. If 95%+ of the suspicious links are NoFollow, breathe easy: no technical action is required on the disavow side. Focus solely on toxic DoFollow links if you detect any.

Document the attack in a spreadsheet: detection date, number of links, source domains, anchor texts used. This record can be useful if you need to justify a suspicious spike to a client or partner. But do not waste hours compiling NoFollow: it's noise without impact.

What mistakes should you avoid in this context?

Number one mistake: uploading a giant disavow file containing thousands of NoFollow domains “just in case.” You clutter your Search Console account unnecessarily and risk accidentally disavowing legitimate domains mixed in the list. The disavow is not a safety net to deploy blindly.

Second mistake: panicking over alerts from third-party tools that artificially inflate toxicity scores with NoFollow. These metrics are purely indicative and do not reflect how Google interprets them. Learn to distinguish between marketing KPIs and actual algorithmic signals.

How can you effectively monitor your link profile?

Set up weekly alerts on your backlink tools to detect abnormal spikes. Configure a threshold (for example: +50 referring domains in 7 days). If an alert triggers, audit the nature of the links: NoFollow or DoFollow, anchor texts, themes of the source sites.

Regularly check the “Links to your site” section in Search Console. Google displays the referring domains it has actually crawled and taken into account. If you detect suspicious DoFollow domains appearing there, it's time to take action. NoFollow links often won't even show up, confirming their lack of impact.

• Filter backlinks by attribute (NoFollow vs DoFollow) in your analysis tool
• Only disavow toxic DoFollow links that are impossible to remove manually
• Document detected attacks with dates, volumes, and sources
• Set up automatic alerts for spikes in new referring domains
• Check Search Console to identify the links actually counted by Google
• Never upload a disavow file containing massive NoFollow “just in case”
