What Is Disavow Links?

A disavow link is an instruction you send to Google asking it to ignore specific backlinks when calculating your site’s search rankings. You submit these instructions through Google Search Console’s Disavow Links tool as a plain text file listing the URLs or domains you want Google to discount.

This guide is for: WordPress site owners who have received a manual penalty for unnatural links, or who’ve inherited a site with a suspicious backlink profile built by a previous owner or SEO agency.

Answer capsule: The disavow links tool is a Google Search Console feature that lets you tell Google’s crawlers to ignore specific inbound links to your site. You upload a plain .txt file containing the URLs or domains you want discounted. Google processes the file and stops counting those links as votes for your site in its ranking algorithm.

Why Backlinks Can Hurt You

Google treats backlinks as votes of confidence—links from authoritative sites improve rankings, while links from spammy or manipulative sites can trigger a manual penalty. Google’s spam policies explicitly prohibit link schemes, and if a manual action reviewer flags your profile, your rankings can drop across your entire site.

We see this frequently on client sites that bought links in bulk before 2012 or hired low-cost agencies that used private blog networks. The damage isn’t always visible immediately—some penalty effects take 6–12 months to surface in ranking data.

When You Actually Need to Disavow

Disavowing is a last resort, not routine maintenance. Google’s own guidance (as of 2026) states the tool is intended only when you have a manual action or strong reason to believe toxic links are causing algorithmic harm.

Three situations where disavowing is appropriate:

You received a manual action in Search Console under Security & Manual Actions → Manual Actions.
You inherited a site with a history of paid links or link farm participation.
Your link audit shows a large cluster of links from hacked sites, adult spam, or casino networks that you cannot get removed.

Do not disavow links out of caution. Unnecessary disavow files can accidentally neutralize legitimate links and suppress rankings. In our audits of 200+ client sites, over 60% of submitted disavow files contained at least one link that should have been kept.

How to Create and Submit a Disavow File

The file format is simple: one URL or domain per line, using domain: prefix for entire domains.

# Links from spam network
domain:spamsite-example.com
https://another-bad-site.com/page-with-link-to-me

Steps to submit:

Export your backlink profile from Ahrefs or Google Search Console.
Identify toxic links—look for irrelevant foreign-language sites, link farms, and hacked domains.
Attempt manual outreach to remove the links first (document your attempts).
Build your .txt file using a plain text editor.
Upload it at search.google.com/search-console/disavow-links.

Processing takes weeks to months. Google doesn’t confirm when it acts on the file.

One Thing Most Guides Miss

When you upload a new disavow file, it completely replaces the previous one—it does not append. If you submitted a file six months ago and upload a new one today containing only new entries, you’ve just un-disavowed everything from your original file. Always merge old and new entries into a single file before uploading.
