What Is a Disavow File?
Definition
A disavow file is a plain text file uploaded to Google Search Console that tells Google to ignore specific backlinks when evaluating your website. It's used to distance your site from spammy or harmful links that could negatively affect search rankings.
When to use a disavow file
Google is generally good at ignoring spammy links on its own. You should only consider disavowing links in specific situations:
- Manual penalty: Google has issued a manual action for "unnatural links" in Search Console.
- Negative SEO attack: A competitor has pointed thousands of spammy links at your site intentionally.
- Past link schemes: You (or a previous SEO provider) participated in paid link schemes and want to clean up.
For most websites with a normal backlink profile, a disavow file is unnecessary. Disavowing the wrong links can actually hurt your rankings.
A competitor's low-DA blog links to your site. Should you disavow it?
Right! Low-DA links aren't automatically harmful. Google ignores most low-quality links on its own. The disavow tool is for serious problems like spam attacks or manual penalties.
A single low-DA link is harmless. Google is smart enough to ignore it. Disavowing should only happen in serious cases: manual penalties, spam attacks, or cleaning up past link schemes.
Disavow vs. remove vs. ignore
| Approach | When to use | Effort |
|---|---|---|
| Ignore | Random low-quality links that Google handles automatically | None |
| Request removal | Clearly spammy links where you can contact the webmaster | Medium — requires outreach |
| Disavow | Manual penalties, negative SEO attacks, or links you can't get removed | Low — upload a text file |
Most SEOs over-use the disavow tool. For the vast majority of sites, Google's algorithms handle spam links without intervention.
How to create and submit a disavow file
- Identify harmful links. Use tools like Ahrefs, Semrush, or Moz to find links from spammy, irrelevant, or penalized domains. Look for patterns: foreign-language spam sites, link farms, or sites with extremely low Domain Authority.
- Try to remove them first. Contact the webmasters of spammy sites and ask them to remove the links. Document your removal attempts.
- Create the file. A disavow file is a plain text (.txt) file. List one URL or domain per line. Use
domain:prefix to disavow all links from a domain. - Upload to Search Console. Go to Google's Disavow Links tool and upload your file for the relevant property.

Do I need a disavow file?
Probably not. Most websites don't need one. Google is good at ignoring spammy links automatically. You only need a disavow file if you've received a manual penalty, you're under a negative SEO attack, or you're cleaning up past link schemes.
Can disavowing links hurt my rankings?
Yes. If you accidentally disavow good links that are helping your rankings, your site can drop. Only disavow links you're confident are harmful. When in doubt, leave them alone.
How long does it take for a disavow file to work?
It can take weeks to months. Google needs to recrawl and reprocess the disavowed links. There's no instant effect. After uploading, be patient and monitor your rankings over the following months.
Can I undo a disavow?
Yes. Upload a new disavow file that removes previously disavowed domains or URLs. Google will eventually reprocess and start counting those links again. You can also remove the disavow file entirely.
