Disavow Link

Tells Google to ignore specific backlinks to your site when evaluating ranking signals, used as a last resort for harmful links you cannot remove yourself.

If you have ever disavowed links based on a third-party toxicity score without checking them first, you already know the tool is easy to misuse.

Key points

  • Use the disavow tool only after you have tried to remove the links by contacting site owners.
  • Upload a new file replaces the old one for that Search Console property, so always keep a backup.
  • Domain-level entries are more efficient than listing individual URLs when spam affects many pages on one domain.
  • Google ignores many spam links algorithmically, so disavow is often unnecessary unless you have a manual action.

The site owner who disavowed too early

An e-commerce site ran a backlink audit and found 300 links flagged as toxic by a third-party tool. Without checking the links, the owner uploaded a disavow file listing all 300. Six weeks later, rankings dropped. A review showed that 200 of those links were nofollow links from legitimate forums and news sites — links Google would have ignored anyway. The owner had removed a natural part of the link profile, and recovery required a new file to rescind the disavows.

Three situations where disavow changes your decision

  • Manual action received If Google issues a manual action for unnatural links, you must disavow the harmful links you cannot remove before you can request reconsideration.
  • Spammy links you cannot remove When outreach fails and the linking site ignores removal requests, disavow is the only way to ask Google to discount those links.
  • PBN networks detected If a backlink audit reveals links from PBN networks, disavow those domains to reduce the risk of a link-spam penalty.

Three ways it goes wrong

  • Disavowing good links Using only third-party toxicity scores without manual review can remove valuable links, including nofollow links that pose no risk.
  • Skipping removal attempts Using disavow as a first step instead of a last resort ignores Google's guidance and may waste the only tool you have for persistent spam.
  • No backup of old file Uploading a new file replaces the existing one; without a backup, you cannot revert if the new file causes problems.

Common questions

Should I disavow toxic backlinks?

Only if you have a clear problem: a manual action, a history of link spam, or links you cannot remove. Third-party toxicity scores alone are not enough.

How do I use the disavow tool?

Create a plain text file listing the URLs or domains you want to disavow, then upload it through Google Search Console's disavow links tool.
