Should you still use the disavow file for SEO?

Is the disavow file still relevant today?

Google's official position is clear: this file only makes sense in a very specific context. If you have received a manual action notification in Search Console for "artificial links" and you have attempted to have these backlinks removed without success, then it becomes relevant.

In all other cases, Google states that its algorithms automatically handle problematic links. The underlying idea is that the engine ignores or devalues these links without you needing to intervene. This assumes that Google correctly identifies toxic signals, which remains a black box for practitioners.

What exactly is a manual action?

A manual action occurs when a human reviewer at Google detects a blatant manipulation of links and applies a penalty. You receive a notification in Search Console, traffic drops sharply, and you must submit a reconsideration request after cleanup.

Without this notification, you have no manual action. Traffic drops can have a hundred causes: algorithm changes, technical issues, failed migrations, increased competition. Disavowing links in this context is more about SEO superstition than rational optimization.

Does Google really detect all toxic links automatically?

This is the central claim of this statement, and it deserves scrutiny. Google claims that its automated systems identify and neutralize artificial links without external help. Theoretically, this means that a clean site should never suffer from a link profile polluted by a competitor or a former unscrupulous provider.

In practice, field observations show cases where negative SEO campaigns or previously purchased links seem to have a negative impact despite no declared manual action. Google does not disclose the error rate of its algorithms or the rate of false positives. The opacity remains total.

• The disavow file is only useful when a confirmed manual action exists in Search Console
• Without a declared penalty, Google claims to manage problematic links automatically without intervention
• A manual action requires proven cleanup + reconsideration request + disavowal of the rest
• No transparency regarding the automatic detection rate or the false positives of algorithms
• Preventive disavowal is considered unnecessary by Google, even potentially counterproductive

Does this statement align with real-world observations?

Partially. It is true that most manual actions have disappeared since Google refined its automatic filters (especially post-Penguin 4.0). Pure manual penalty cases have become rare and are reserved for blatant and repeated abuses. Most link issues are now resolved through algorithmic ignorance rather than punishment.

However, practitioners regularly report cases where manual cleanup + disavowal seems correlated with a recovery of positions, even without prior manual action. These observations are anecdotal, scientifically non-reproducible, and may be coincidental. Google provides no means to objectively measure the impact of a disavowal outside the context of a penalty.

When might this rule not be sufficient?

If you inherit a site with a shady history (expired domain purchase reused, former PBN network), you may find yourself with thousands of spammy links that Google has never addressed. Officially, these links are “ignored.” In reality, some sites inexplicably stagnate despite solid content and a clean technique.

Another edge case: orchestrated negative SEO. A competitor may massively point bad links to your site. Google asserts that this has no negative effect, but isolated reports contradict this assurance. Without visible manual action, you theoretically have nothing to do. Nonetheless, some choose to disavow as a precaution, which Mueller explicitly discourages.

What nuances should be applied to this official position?

Google has an interest in minimizing the use of the disavow file: each submission generates verification work on the engine side, and encouraging massive disavowal would open the door to errors (accidentally disavowing good links). Mueller's statement also protects Google from accusations of not providing enough tools: “You don’t need it, except in extreme cases.”

The problem is that Google publishes no data on the real effectiveness of its automatic filters. How many toxic links go unnoticed? How many good links are mistakenly devalued? Impossible to know. This asymmetry of information places SEOs in an uncomfortable position: blindly trusting or disavowing out of caution, risking a loss of link juice.

What should you do if you don't have a manual action?

Nothing. Really. Do not use the disavow file if Search Console shows no manual penalties. Focus on acquiring quality links, improving content, and fixing technical issues. Time spent auditing thousands of backlinks for preventive disavowal is statistically better invested elsewhere.

If you notice a traffic drop, start with a complete diagnosis: server logs, Core Web Vitals, cannibalization, content freshness, recent algorithm changes. Toxic links are rarely the primary cause of a drop unless proven otherwise. The obsession with disavowal often distracts from a structured analysis.

How to proceed in the case of a confirmed manual action?

You receive an explicit notification in Search Console > Manual Actions. At this point, and only at this point, the disavow file becomes a necessary tool. The standard procedure: identify problematic links, try to have them removed (emails to webmasters, removal requests), then disavow what remains.

Google expects you to demonstrate a serious cleanup effort before lifting the penalty. Sending only a disavow file without proof of prior contact can lead to a reconsideration request rejection. Document every step: screenshots, emails sent, responses received. This file accompanies the reconsideration request.

What mistakes should you absolutely avoid?

Never disavow an entire domain without valid reason. Some SEO tools flag directories or aggregators as “toxic” that, while mediocre, do not actively harm. Disavowing a legitimate domain that sends you qualified traffic is a costly mistake that is difficult to reverse.

Another classic trap: disavowing links simply because they have a “high spam score” according to a third-party tool. These metrics are approximations, not Google verdicts. A link from an old forum poorly rated by Moz may be perfectly harmless in Google's eyes. Prioritize human judgment over automated scores.

• Check Search Console: no manual action = no need to disavow
• Document all cleanup efforts: emails, dates, responses received before disavowing
• Disavow by URL rather than by domain, except in cases of obvious mass spam
• Do not blindly rely on toxic scores from third-party tools without manual analysis
• Test the impact gradually: disavow in small batches, measure, adjust
• Regularly reevaluate your disavow file to remove what no longer applies
