TL;DR: A list of backlink URLs or domains submitted through Google Search Console asking Google to ignore them when ranking your site.
In a nutshell
Once useful for cleaning up after manipulative link building, the disavow file is rarely needed in 2026. Google’s SpamBrain algorithm ignores most low-quality links automatically. Only use it for active manual penalties or clear negative SEO attacks. Example: a site recovering from a black-hat agency’s spam links may genuinely need one.
Quick answer: A disavow file is a list of backlink URLs or domains submitted to Google through Search Console asking Google to ignore them when assessing your site. Once useful for cleaning up after manipulative link building, the disavow file is rarely needed today: Google’s algorithms now ignore most low-quality links automatically.
What Is a Disavow File?
A Disavow File is a file used by webmasters to inform search engines, such as Google, that they do not want certain backlinks to be counted as part of their website’s backlink profile. This is often used to prevent spammy, low-quality, or toxic backlinks from negatively impacting a website’s search engine rankings. By submitting a disavow file, webmasters can disassociate harmful backlinks from their site, preventing penalties or ranking drops caused by those links.
At BrisTechTonic, we help businesses manage their backlink profiles by identifying and disavowing harmful links. By proactively using disavow files, we ensure that your website stays in good standing with search engines, improving your SEO performance.
Why Disavow Files Matter
Disavow files are important for maintaining a healthy backlink profile and protecting your website from penalties caused by toxic or spammy backlinks. Here’s why they matter:
- Protects from Penalties: Search engines like Google can penalise websites that have unnatural or low-quality backlinks. By submitting a disavow file, you can prevent these links from negatively impacting your rankings.
- Improves Link Profile Health: A disavow file helps ensure that only high-quality, relevant backlinks are considered part of your link profile, which strengthens your SEO efforts.
- Reduces Risk of Google Penalties: Google’s Penguin algorithm, which targets spammy link building tactics, can result in ranking drops for websites with toxic backlinks. A disavow file helps to mitigate the risk of being penalised.
- Maintains Trust with Search Engines: By proactively managing your backlink profile and disavowing harmful links, you demonstrate to search engines that your site follows best SEO practices, which can improve long-term rankings. Google’s own guidance on what counts as a quality link sits in the Google Search Central docs.
How to Create and Submit a Disavow File
Creating and submitting a disavow file involves several key steps. Here’s how we help businesses manage their disavow process:
1. Identify Harmful Backlinks
Before submitting a disavow file, it’s crucial to identify harmful backlinks. We use tools like Google Search Console, Ahrefs, and Majestic to analyse your referring domains and find links that are spammy, irrelevant, or from low-quality websites. For a beginner’s primer on what makes a link worth keeping, see the Moz Beginner’s Guide to SEO.
2. Review and Prioritise Links
Not all backlinks are harmful, so we carefully review and prioritise links that should be disavowed. Links from websites with poor domain authority, irrelevant content, or suspicious behaviour are typically flagged for disavowal.
3. Create the Disavow File
The disavow file is a plain text file (TXT) that contains a list of URLs or domains you want to disavow. Each URL or domain should be listed on a separate line in the file. We ensure that the disavow file is formatted correctly for submission to Google’s Disavow Tool.
4. Submit the Disavow File to Google
Once the disavow file is created, we submit it to Google via the Disavow Tool in Google Search Console. This notifies Google that you no longer want certain backlinks to be counted as part of your website’s backlink profile.
5. Monitor Your Backlink Profile
After submitting the disavow file, we monitor your backlink profile regularly to ensure that no new harmful links are added. We continue to use tools like Google Search Console to track any changes in your rankings or backlink profile.
How Disavow Files Affect SEO
Disavow files can have a significant impact on SEO by improving your backlink profile and protecting your site from negative SEO effects. Here’s how disavowing harmful links affects SEO:
- Improves Search Rankings: By removing toxic backlinks, your website’s backlink profile becomes healthier, which can lead to improved rankings in search engine results pages (SERPs).
- Restores Trust with Google: Removing harmful links signals to Google that you are following best SEO practices, which can restore trust with the search engine and prevent penalties.
- Prevents Ranking Declines: Toxic backlinks can cause your website to experience ranking drops, particularly with algorithms like Google Penguin. By disavowing these links, you can prevent ranking declines and maintain a strong SEO performance.
- Boosts Organic Traffic: By improving your backlink profile and search rankings, disavowing harmful links can result in increased organic traffic over time, bringing more targeted visitors to your website.
Common Disavow File Mistakes
- Disavowing Good Links: Disavowing high-quality backlinks can harm your SEO efforts. We carefully review each backlink before adding it to the disavow file to ensure that only harmful links are included.
- Not Monitoring Backlink Profile: After submitting a disavow file, it’s essential to continuously monitor your backlink profile to ensure new harmful links don’t appear. We conduct regular audits to maintain a clean backlink profile.
- Submitting Inaccurate Files: An incorrectly formatted disavow file can cause issues. We ensure that the disavow file is created and submitted properly, with the correct URLs or domains listed.
- Waiting Too Long to Disavow Links: Waiting too long to address toxic backlinks can result in long-term damage to your SEO. We take a proactive approach and act quickly when we identify harmful links.

Frequently Asked Questions
Should I use a disavow file?
Rarely. Google’s SpamBrain algorithm now identifies and ignores most low-quality links automatically. Disavow is only useful when you have evidence of a manual penalty for unnatural links, or when you can clearly identify deliberate negative SEO attacks. For most sites, leaving links alone is safer than disavowing.
How do I submit a disavow file?
Through Google Search Console’s Disavow Links tool (search.google.com/search-console/disavow-links). Upload a plain text file listing the URLs and domains you want Google to ignore. Each entry on its own line; domain entries prefixed with "domain:". Google takes weeks to fully process changes.
Can I damage my SEO by disavowing the wrong links?
Yes. Disavowing legitimate backlinks loses ranking signal. The risk is highest for sites with smaller backlink profiles where each link contributes meaningfully. The conservative rule: only disavow when you have specific evidence (a manual penalty notice, identifiable spam attack) rather than out of general worry.
Is the disavow file still relevant in 2026?
Less than it used to be. Google has consistently said it discounts low-quality links automatically and most sites do not need to disavow. The exception remains active manual penalties for unnatural links and clear cases of negative SEO. For everyone else, time is better spent on positive SEO work.

Disavow files are a niche tool that most sites should not be using. We assess each client’s backlink profile and only recommend disavow when there’s genuine evidence it’s needed.
