What Is a Disavow File? A Complete Beginner's Guide
Learn what a Google disavow file is, when you need one, how to create it, and how to upload it to Google Search Console. Plain English, no jargon.
What is a disavow file?
A disavow file is a simple text file that you upload to Google Search Console. It tells Google to ignore specific backlinks when deciding where to rank your website in search results.
Think of it like a blocklist. You're saying to Google: "These websites are linking to me, but I don't want you to count those links. Please ignore them."
Why would you need one?
Every website on the internet has backlinks — other sites that link to it. Some of these links are good. They come from reputable websites and help your search rankings.
But some links are bad. They come from spammy, low-quality, or suspicious websites. These are called toxic backlinks, and they can drag your rankings down.
Common sources of toxic backlinks include:
- Spam directories and link farms
- Fake news wire services
- Private blog networks (PBNs)
- Hacked or abandoned websites
- Automated link-building tools you didn't authorise
If your site has accumulated too many toxic backlinks, a disavow file tells Google to stop counting them against you.
When should you use a disavow file?
Google themselves say you should only use the disavow tool when you have a substantial number of spammy or low-quality links pointing to your site, and those links are causing problems.
You might need a disavow file if:
- Your search rankings have dropped and you suspect bad backlinks
- You received a manual action from Google for unnatural links
- A competitor is running a negative SEO attack against you
- You previously used link-building services that created spammy links
- An audit of your backlink profile shows a high proportion of toxic domains
You probably don't need one if your backlink profile is mostly clean. A few spam links here and there are normal — Google is generally good at ignoring them automatically.
What does a disavow file look like?
It's a plain text file (.txt) with one entry per line. Each line starts with domain: followed by the domain you want Google to ignore.
# Spam directories
domain:spamsite.xyz
domain:linkfarm.top
domain:seomanipulation.club
Fake news wires
domain:fakenewswire.com
Lines starting with # are comments — they're just notes for yourself and Google ignores them.
You can also disavow individual pages instead of entire domains, but domain-level disavows are almost always the better choice. If one page on a domain is spammy, the whole domain probably is.
How to create a disavow file
There are two approaches:
Manual approach: Export your backlink data from Google Search Console, review every link, decide which ones are toxic, and type the domain names into a text file. This works but takes hours, especially for sites with thousands of backlinks. Automated approach: Use a backlink audit tool like Disavow that scans your backlink profile, classifies each link as toxic, suspicious, or clean, and generates the disavow file for you. This takes minutes instead of hours.How to upload it to Google Search Console
Google will process the file. It can take 2 to 6 weeks before you see any effect on your rankings. Google needs time to recrawl the disavowed links and update their index.
Will disavowing links hurt my rankings?
Only if you disavow the wrong links. If you accidentally tell Google to ignore a high-quality backlink from a reputable website, you lose the ranking benefit of that link.
This is why accurate classification matters. A good backlink audit tool should never flag legitimate sites like BBC, Wikipedia, or industry publications as toxic.
What if I make a mistake?
You can always upload a new disavow file to replace the old one. Google only uses the most recently uploaded file, so you can remove any entries you added by mistake.
That said, it takes another 2-6 weeks for Google to process the change, so it's better to get it right the first time.
How often should I review my disavow file?
We cover this in detail in our guide on how often you should audit your backlinks, but the short version:
At minimum, check your backlink profile quarterly. If your site is in a competitive niche or has been targeted by spam before, monthly reviews are safer.
New toxic backlinks appear constantly. Spammers don't stop just because you cleaned up last month. Regular audits catch new threats before they accumulate enough to affect your rankings.
