$ cat Disavow Links: The Real Rules
What the Google disavow tool actually does, the two conditions Google says justify it, why "toxic backlinks" scores mislead, and a checker that fixes your disavow file before you upload it.
To refuse to accept responsibility for, or connection with, something. In SEO: to ask Google to ignore specific links pointing at your site when it assesses your site.
The Google disavow tool lets a site owner upload a list of URLs or domains whose links Google should ignore. It was launched in 2012 for sites cleaning up after paid-link penalties. [2] Since then a whole industry has grown up around "toxic backlinks" audits, and many sites disavow links that were never hurting them. This chapter sets out what Google actually says, how to build a valid file if you need one, and why negative SEO spam usually does not call for it.
1 · What the disavow tool does
You upload a plain text file to the tool for a Search Console property. Google then ignores the listed links when it evaluates that site, after reprocessing that "can take a few weeks". The links still appear in your Links report; disavowing doesn't delete them from the web. [1] confirmed
Four details catch people out: [1] confirmed
- It does not support Domain properties. Use a URL-prefix property.
- There is one list per property. Uploading a new file replaces the old one completely, so always upload the full list.
- A list applies to that property and its child properties; if you have separate http and https properties, each needs its own.
- You can withdraw everything with Cancel disavowals, which also takes weeks to take effect.
2 · When Google says to use it
Google's help page gives two conditions, and both must be true: you have a considerable number of spammy, artificial, or low-quality links pointing at your site, and those links have caused, or likely will cause, a manual action. It adds that "in most cases, Google can assess which links to trust without additional guidance." [1] confirmed
In practice that means: you have a manual action for unnatural links in Search Console, or you (or an agency you hired) built or bought links at scale and want to get ahead of one. Random spam links you didn't create are not on that list. interpretation
3 · The "toxic backlinks" myth
Many SEO tools grade backlinks with a "toxicity" score and recommend regular disavowing. Google's John Mueller has been blunt about it: "The concept of toxic links is made up by SEO tools so that you pay them regularly." He has also said the tool is not something you would need on a regular basis, and that he'd treat a tool recommending routine toxic-link cleanup as a red flag. [3] [4] confirmed
The risk runs the other way too. Disavowing good links by mistake removes value you had. Third-party toxicity scores are guesses from outside Google; none of them can see how Google is treating a link. interpretation
4 · Negative SEO and link spam floods
Sites regularly get hit with waves of junk links: scraper pages, auto-generated blogs, foreign-language spam, links from hacked sites. Google's position is that its systems ignore links like these, and Mueller told a site owner worried about hundreds of thousands of links from junk blog posts that they are "just the usual junk that you can ignore." [5] confirmed A flood like this is unpleasant to watch in a backlink tool, but on its own it isn't a reason to disavow. If rankings drop at the same time, look first at algorithm updates, technical changes and content quality before blaming the links. interpretation
The search manipulation chapter covers how negative SEO attacks are attempted and why most fail. practitioner
5 · Disavow file format
The rules are strict and an error rejects the whole upload. [1] confirmed
| Rule | Detail |
|---|---|
| File | Plain text, name ending in .txt, UTF-8 or 7-bit ASCII |
| One per line | A full URL (https://spam.example/page.html) or a domain (domain:spam.example) |
| Domains | Use the domain: prefix to cover a domain or subdomain and everything on it |
| No subpaths | You can't disavow a folder such as spam.example/blog/; list URLs or the whole domain |
| Comments | Lines starting with # are ignored |
| Limits | 100,000 lines (blank and comment lines count), 2 MB, URLs up to 2,048 characters |
Paste your disavow list. The checker flags lines Google would reject, rewrites bare hosts and subpaths into valid lines, removes duplicates and URLs already covered by a domain: line, and checks the size limits. Everything runs in your browser; nothing is uploaded.
6 · Uploading and checking a disavow file
- Export your links from Search Console's Links report (or a backlink tool) and decide line by line. Prefer
domain:for sites that are spam throughout. - Try to get the worst links removed at the source first. Google recommends this before disavowing. [1]
- Open the disavow tool, choose the URL-prefix property, and upload. Errors show immediately and the old list stays in place if the new one fails.
- To check what is currently disavowed, open the tool and select the property: it shows a summary of the disavowed pages and domains. Keep your own master copy of the file, because the next upload replaces it.
- If you have a manual action, file a reconsideration request that explains what you removed, what you disavowed, and how you stopped building those links.
___________________________________________ / \ | I, the undersigned webmaster, do hereby | domain:spam-network.example | DISAVOW all links from the following, | domain:linkfarm.example | which I did not ask for, did not want, | # processed in a few weeks | and Google was probably ignoring anyway. | # still in your Links report \___________________________________________/
7 · Is the disavow tool going away?
Bing removed its disavow tool in 2023. Asked whether Google would follow, Mueller replied in May 2024: "At some point, I'm sure we'll remove it." No date has been given and the tool remains available as of this revision. [4] confirmed The direction is clear: Google expects its systems to handle unnatural links without help from site owners. interpretation
8 · What experts get wrong
"Disavow monthly as maintenance." Google's guidance is the opposite: use it only for large-scale artificial links tied to a manual action risk. confirmed
"Disavowing will bring my rankings back." If Google was already ignoring those links, disavowing them changes nothing. confirmed
"Upload just the new domains." Each upload replaces the whole list. Upload the complete file every time. confirmed
"Disavow will clean up a hacked site." Spam on your own site is a hack cleanup problem, not a links problem. interpretation
Disavow links: common questions
What does disavow mean in SEO?
It means telling Google to ignore specific links pointing at your site. You do it by uploading a list of URLs or domains to Google's disavow tool in Search Console.
Should I disavow toxic backlinks?
Usually not. Google says it can assess which links to trust in most cases and recommends disavowing only when you have many artificial links that caused, or likely will cause, a manual action.
What is the format of a disavow file?
A .txt file in UTF-8 or 7-bit ASCII with one URL or one domain: entry per line, optional # comments, up to 100,000 lines and 2 MB.
How do I check which links I have disavowed?
Open the disavow tool and select the property to see a summary of what is disavowed. Keep your own copy of the file. Disavowed links still show in the Links report.
How long does a disavow take to work?
Google says it can take a few weeks to incorporate the list after a successful upload.
Can I disavow links for a Domain property?
No. The tool does not support Domain properties; use a URL-prefix property, and upload separate lists for http and https if you have both.
