In early September 2026, a site owner asked Google directly why rankings never recovered after they disavowed a set of links. Google's Search Liaison, John Mueller, gave a clear answer: the tool "does have effects, but it has its place & time." The problem in that specific case was not the tool failing - it was what led the owner to need it in the first place.
For US site owners, "should I disavow this" tends to come up in the exact same moment every time: after a ranking drop, after a suspicious jump in backlinks, after suspecting a competitor of targeting the site with negative SEO. This breaks down when disavow is the right move and when it just eats time while adding risk.
What Happened in This Case
The site had been buying guest posts and links through Fiverr - a freelance marketplace known for exactly this kind of manipulative link. The owner disavowed a batch of those links expecting rankings to bounce back. They did not, and the owner asked Mueller whether the tool even works.
Mueller's response reframed the whole situation: "does have effects, but it has its place & time." He also noted specifically that disavowing a handful of links will not tank a site out of search - meaning this site's real issue was never a broken tool. The purchased links created the risk to begin with; disavowing them after the fact does not erase that.
When Disavow Actually Helps
- You have a manual action in Search Console specifically for unnatural links, with Google pointing directly at your backlink profile.
- You know for certain you previously bought or built links at scale - link marketplaces, bulk guest posts, spun comment spam - and want to formally cut ties before rebuilding cleanly.
- The site is under an active negative SEO attack: dozens or hundreds of obviously spammy links from clearly toxic domains showing up in a short window.
When Disavow Wastes Time
- Rankings dropped but the link profile looks otherwise normal - no sudden anomalies, no manual action. The cause is almost always something else: content, technical SEO, or an algorithm update landing around the same time.
- You are disavowing links "just in case" without checking whether they are actually toxic. Google already ignores most low-authority or directory links automatically.
- You are treating disavow as a substitute for figuring out why purchased links ended up in the profile in the first place - without fixing that source, the problem repeats.
The Real Mistake Behind This Case
The genuine mistake was never the disavow submission - it was buying links from Fiverr in the first place. Disavow here treats a symptom after the fact instead of preventing the problem. A link profile built through bulk guest posts and link marketplaces makes a ranking drop a matter of when, not if, and no disavow file undoes a signal Google's systems already picked up on.

How to Use the Tool Correctly
- Check Search Console for a manual action first, under "Manual Actions." Without one, disavow is unlikely to fix a current ranking issue.
- Export your full backlink profile and look for real anomalies - a sudden spike from one domain type, obviously spammy sources, anchor text you never built naturally.
- Build the disavow file narrowly - specific domains or URLs with proven toxicity, not the whole profile "to be safe."
- Submit through the official disavow tool and wait for recrawling - the effect is not immediate and usually takes weeks.
- Fix the underlying source at the same time: stop buying questionable links if that has been happening, and shift toward earning links naturally.
Why This Question Keeps Coming Up
The same "should I disavow" question resurfaces every few months, almost always right after a ranking drop that has nothing to do with links at all. Panic pushes people toward the most actionable-feeling option, and disavow feels more actionable than "diagnose properly and wait." That pattern is exactly why a documented, specific case like this one is worth more than general advice - it gives site owners something concrete to compare their own situation against instead of reasoning from anxiety.
What a Clean Link Profile Looks Like
Sites that never end up needing disavow tend to share a pattern: links accumulate slowly through genuine mentions, coverage, and outreach rather than being purchased in bulk from one source at one point in time. That gradual, varied buildup is itself one of the signals Google's systems already use to separate natural growth from manufactured link building - which is a big part of why disavow rarely helps a site that never manipulated its own profile in the first place.
FAQ
Can disavow hurt a site? The tool does not penalize a site directly - it asks Google to ignore the listed links. The real risk is disavowing genuinely valuable links by mistake, which can cost you some of their positive effect.
How many links need disavowing before there is an effect? Mueller stated plainly that disavowing a handful of links will not sink a site out of search. The real effect depends on how large and toxic the underlying problem actually is.
How fast does disavow show results? Google has not given a fixed timeline - the effect kicks in after the disavowed links get recrawled, usually a matter of weeks.
Should disavow be part of routine site maintenance? No, Google does not recommend it as a routine practice. Regular preventive cleanup with no specific problem to fix is a waste of time, and sometimes a sign worth investigating where questionable links are coming from.
What if rankings dropped and disavow doesn't help? Look at more likely causes: content changes, technical issues like speed or indexing, or timing that lines up with a Google algorithm update.
Bottom Line
Google's disavow tool works exactly as described - but only for a specific, proven toxic-link problem, not as a fix for falling rankings in general. Check for a manual action first, look for real anomalies in the profile, and fix the root cause if it involves buying manipulative links, as it did here.
