Identifying & Disavowing Toxic Links
Not all backlinks are beneficial. Toxic or spammy links can harm your search rankings and potentially result in a Google penalty. Learn how to identify and handle problematic links.
Only disavow links if you have a manual penalty or are certain the links are harmful. Google is good at ignoring low-quality links on its own.
Signs of Toxic Links

- Links from hacked or malware sites
- Exact-match anchor text from many sources

- Comment spam links
- Links from thin or duplicate content sites

The Disavow Process
1
Audit
Export your backlinks from Google Search Console
2
Analyze
Review each link for quality and relevance
3
Remove
Try to get links removed manually first
4
Disavow
Submit remaining toxic links to Google
Creating a Disavow File
The disavow file is a plain text file (.txt) that you upload to Google Search Console.
# Example disavow file
# Disavowing individual URLs
https://spam-site.com/bad-link-page.html
https://low-quality-blog.net/spammy-post
# Disavowing entire domains (recommended for link farms)
domain:linkfarm.com
domain:spam-directory.net
domain:pbn-network.org
Disavow Best Practices
- Be conservative - Only disavow links you're certain are harmful
- Try removal first - Contact webmasters to request link removal before disavowing
- Document everything - Keep records of removal requests for potential reconsideration requests
- Use domain: prefix - For spam domains, disavow the entire domain, not individual URLs
- Review periodically - Audit your backlinks quarterly to catch new toxic links
When NOT to Disavow
- Links from sites you simply don't recognize
- Low authority links that aren't actually spammy
- Competitor sites (unless they're actual spam)
- Nofollow links (they don't pass PageRank anyway)
- Links you're unsure about - when in doubt, leave them out
Manual Penalty Recovery
If you've received a manual action for unnatural links, follow these steps:
- Download your complete backlink profile from Google Search Console
- Analyze each link and categorize by toxicity level
- Send removal requests to webmasters (document your efforts)
- Create and submit a disavow file for links you couldn't remove
- Submit a reconsideration request with documentation of your cleanup efforts
