Disavowing backlinks is a technical SEO process used to tell Google to ignore specific inbound links that may harm your website’s rankings. These links often come from spammy, irrelevant, or manipulative sources that violate Google’s quality guidelines and can trigger manual actions or algorithmic suppression.
The Disavow Tool in Google Search Console allows site owners to submit a list of domains or URLs they want excluded from link evaluation. This is not a general cleanup method—it’s a defensive action reserved for serious link-related risks. Related concepts include toxic backlinks, negative SEO, unnatural links, and manual penalties.
SEO professionals, marketers, and site owners use this tool to recover from penalties, mitigate link spam, and protect their backlink profile. It helps maintain ranking stability in competitive or high-risk SEO environments.
In this guide, you’ll learn when to use the Disavow Tool, how to identify harmful backlinks with tools like SEMrush and Ahrefs, how to format a disavow file correctly, and what mistakes to avoid.
What Does It Mean to Disavow Backlinks?
Disavowing backlinks means you are telling search engines like Google to ignore certain links that point to your website. These are usually links from bad or spammy websites that you don’t want associated with your domain. If your site has too many of these harmful links, your rankings can suffer in search results.
When you disavow links, you’re not removing them from the internet. Instead, you are asking Google not to count them when evaluating your site’s authority and trustworthiness. This can help prevent penalties or mitigate damage from manipulative backlinks.
To disavow backlinks, you need to:
- Create a .txt file listing the unwanted links or domains
- Upload the file using Google’s Disavow Tool
- Let Google decide whether to honor the request based on its link evaluation systems
A few important points to remember:
- Google treats your disavow file as a suggestion, not a final decision. It will only ignore the links if they appear genuinely harmful.
- The links are not deleted. They remain visible in reports but are no longer factored into rankings if disavowed successfully.
If used correctly, disavowing can help clean up your backlink profile and reduce risk. But if you remove good links by mistake, it can weaken your SEO performance instead of improving it.
Let’s now explore when disavowing backlinks is actually necessary—and when it’s better to leave them alone.
What Types of Links Should You Disavow (And Which to Keep?)
Disavow only backlinks that clearly violate Google’s guidelines or threaten your SEO integrity. These include links built through manipulative practices such as link farms, paid placements, or irrelevant PBNs (Private Blog Networks). Google may interpret these as attempts to manipulate PageRank and apply penalties.
If a link is not causing harm or violating policies, it should not be disavowed.
Disavow if the Backlink
- Comes from spammy directories, scraped content sites, or auto-generated blogs.
- Is part of a known PBN or interlinked low-quality domain cluster.
- Appears in bulk across foreign-language sites unrelated to your niche.
- Uses over-optimized anchor text (e.g., exact-match keywords repeated unnaturally).
- Belongs to a domain that has been deindexed or penalized.
Do Not Disavow if the Backlink
- Comes from a niche-relevant blog with low traffic but real content.
- Was naturally earned through citations, mentions, or editorial value.
- Has low Domain Rating (DR) or Domain Authority (DA) but does not violate guidelines.
- Has no clear signs of manipulation, even if unexpected or unfamiliar.
Manual review is required. SEO tools like Semrush or Ahrefs can assist with link scoring (e.g., Toxic Score or DR), but human judgment must guide the final disavow list. Over-reliance on automated tools can result in loss of valuable link equity and unnecessary disavowal of safe backlinks.
Common Types of Bad Backlinks
Bad backlinks typically originate from domains built solely to manipulate search rankings. These links offer no editorial value, lack relevance, and may violate Google’s spam policies. They should be disavowed if they are verified as harmful through a structured review process.
Common Sources of Toxic Backlinks Include
- Paid links that pass PageRank without disclosure (e.g., not marked as nofollow or sponsored).
- PBNs (Private Blog Networks) used to build artificial link authority between low-quality sites.
- Spammy blog comments with keyword-rich anchors placed across unrelated sites.
- Low-quality directories that accept any submission without vetting.
- Auto-generated pages with scraped, duplicated, or AI-spun content linking to your domain.
- Foreign-language domains with no topical or regional relevance to your website.
- Deindexed or penalized domains identified through tools like Ahrefs or Google Search.
Manually Verify Each Domain Before Disavowing
- Website type (e.g., directory, scraper, blog network)
- Site content quality and originality
- Publisher intent (informational vs. SEO manipulation)
- Moz spam score, ideally using MozBar or Link Explorer
- Organic traffic and index status via tools like Ahrefs or Google Search
Only include a domain in your disavow file if multiple red flags confirm that it poses a real SEO risk.
Step-by-Step Guide: How to Use Google’s Disavow Tool to Remove Toxic Backlinks
Google’s Disavow Tool allows you to ask Google to ignore harmful backlinks that may damage your site’s SEO. This is a recovery action—not a routine SEO task—and should only be used when there’s a clear risk of penalties from spammy or manipulative links.
Follow these steps to safely disavow backlinks using Google’s tools:
1. Export Your Backlink Profile
Use Google Search Console to download the backlinks that Google currently associates with your website.
- Navigate to Links > External Links > More sample links > Export
- This list represents the backlinks that are actually recognized by Google and eligible for disavowal.
Optional: Tools like Ahrefs or Semrush can help identify toxic patterns, but they are not required for submitting a disavow file. Only links visible in GSC matter to Google.
2. Identify Toxic Backlinks for Disavowal
Manually review each domain or URL to determine whether it violates Google’s link quality guidelines.
Evaluate:
- Site type and purpose (e.g., link farm, scraper, expired domain)
- Content relevance and originality
- Link intent (natural mention vs. paid placement)
- Anchor text manipulation
- Moz Spam Score
- Domain index status and authority signals
3. Create the Disavow File (.txt)
Format a plain text file using UTF-8 encoding. Each entry must appear on a separate line.
Examples:
# Disavow list created August 2025 – toxic link cleanup
domain:spamdirectory.example
domain:pbn-network.example
http://lowqualitysite.example/page.html
- Use domain: to disavow all links from a domain
- Use full URLs only if disavowing a specific page
- Use # for internal notes—Google ignores these lines
4. Upload the File to Google’s Disavow Tool
Access the Google Disavow Tool.
- Choose the correct URL-prefix property (the tool does not work for domain properties)
- Upload your .txt file
- Confirm submission. Google will show the number of domains and URLs disavowed
Important Notes
- Uploading a new file replaces the old one
- Google does not provide notifications or success confirmations
- Changes may take several weeks to several months to reflect in rankings, depending on crawl and index frequency
Used correctly, the disavow tool helps you defend your site from link-based penalties and algorithmic suppression. Misused, it can remove valuable link equity and damage your SEO performance.
Here is the T-Rank–aligned version of H3: How to Format a Disavow File Properly, written for clarity, technical accuracy, and snippet readiness:
How to Format a Disavow File Properly
A disavow file must follow Google’s exact syntax to be accepted. It is a plain text file (.txt) that lists the specific URLs or entire domains you want Google to ignore when evaluating your site’s backlinks.
Formatting Rules
- Use one entry per line.
- Use domain: to disavow all links from a domain or subdomain.
- Use a full URL to disavow a single page only if necessary.
- Use # at the beginning of a line to include comments. These are ignored by Google but help document reasons or dates.
Examples of Correct Format
# Disavow file – submitted Sept 2025
domain:spam-example.com
http://badsite.com/page-with-link.html
domain:expired-directory.net
Technical Requirements
- File must be saved as .txt
- Encoding must be UTF-8 or 7-bit ASCII
- Maximum size: 2MB or 100,000 lines
Avoid Common Mistakes
- Do not use site: (only domain: is accepted for domains)
- Do not use quotes, wildcards, or trailing slashes
- Do not include entries with typos or incomplete URLs
Once the file is correctly prepared, upload it through the Google Disavow Tool. Google will ignore improperly formatted lines.
Tip: Always keep a backup of each submitted version. Uploading a new file replaces the previous one.
How Long Does It Take to See Results?
Google does not process disavow files instantly. The impact of disavowing backlinks is gradual and depends on how quickly Googlebot recrawls and reindexes the disavowed domains or URLs.
Estimated Timeline
- Initial processing: Begins within a few days of uploading the file.
- Ranking adjustments: May take 2 to 6 weeks, depending on crawl frequency.
- Full effect: Can take 3 to 6 months or longer for widespread link removal to reflect in rankings.
Important to Know
- You will not receive any confirmation or alerts from Google after submitting a disavow file.
- If the disavow is related to a manual action, rankings will not improve until Google reviews and lifts the penalty—often through a formal reconsideration request.
- If there is no penalty, ranking improvements (if any) will appear incrementally, especially if toxic links were suppressing authority.
Disavowing does not guarantee a rankings boost. Its purpose is to stop further harm from low-quality or manipulative backlinks.
How to Update or Cancel a Disavow File
Google’s Disavow Tool does not allow you to add or remove entries line by line. Any new upload fully replaces the previous disavow file.
To Update an Existing Disavow File
- Download your current file from the Disavow Tool.
- Add new entries or remove old ones as needed.
- Save the revised version as a .txt file in UTF-8 encoding.
- Re-upload the full file using the same Disavow Tool.
To Cancel All Disavowed Backlinks
- Log into the Disavow Tool.
- Choose the relevant URL-prefix property.
- Click “Cancel Disavowals” to delete the current file entirely.
- Google will begin reassessing previously ignored links during future crawls.
Key Notes
- Google does not notify you after an update or cancellation.
- Restored links (after canceling) will not affect rankings immediately.
- Use version tracking and backups to avoid unintentional loss of previous entries.
Tip: Maintain a master disavow file with timestamps and comments. This ensures consistency across updates and avoids mistakenly un-disavowing harmful domains.
How to Identify and Disavow Toxic Backlinks Using SEMrush and Ahrefs
SEO tools like SEMrush and Ahrefs make it easier to identify harmful backlinks that may be affecting your search rankings. While they do not directly remove or disavow links, they provide data-driven insights to help you build a clean and accurate disavow file for submission in Google Search Console.
These tools assist in:
- Flagging suspicious domains based on link quality signals.
- Analyzing anchor text, domain trust, and link context.
- Exporting filtered lists in a format ready for manual or tool-assisted disavowal.
Using SEMrush to Audit and Disavow Backlinks
SEMrush offers a dedicated Backlink Audit tool that helps identify toxic backlinks using algorithmic signals. It also provides an interface to organize disavow lists for Google Search Console. While SEMrush does not directly remove backlinks, it streamlines the audit and export process.
Follow these steps to disavow backlinks using SEMrush:
Step 1: Open the Backlink Audit Tool
Navigate to the Projects section in SEMrush. Select your domain, then click on Backlink Audit under the Link Building tools.
Enter your domain in above project section.After that scroll down the page and click on Backlink audit tool.
Step 2: Analyze Toxicity Score and Backlink Overview
Once loaded, SEMrush displays an Overall Toxicity Score. This metric categorizes your backlinks into:
- Toxic
- Potentially Toxic
- Non-Toxic
It also shows how many domains and backlinks were analyzed, along with key metrics like follow/nofollow percentage and Authority Score.
Step 3: Review and Verify Suspicious Links
Go through domains flagged as toxic. Click on each to review the:
- Referring domain
- Anchor text
- Target URL
- Link placement context
- SEMrush risk indicators (e.g., deindexed domain, link directory patterns)
👉 Important: Manually validate each domain by checking content quality, domain intent, and link placement relevance. Do not blindly rely on automation.
Step 4: Move to Disavow List
Select confirmed toxic domains or URLs and click “Move to Disavow”. SEMrush will store them in a dedicated disavow list within your project.
Step 5: Export and Submit the Disavow File
From the Disavow list section, click “Export to .txt”. The file is already formatted for upload to Google’s Disavow Tool. If you’ve connected your Google Search Console, you can submit it directly through SEMrush.
Final Notes
- Only disavow domains that clearly violate Google’s link guidelines.
- Maintain a local backup of the disavow file before submission.
- Recheck toxicity scores quarterly or after major link-building campaigns.
Using Ahrefs to Build a Manual Disavow List
Ahrefs does not include a built-in disavow submission feature, but it remains one of the most effective tools for backlink analysis and disavow file preparation. Its vast link index, filter options, and domain-level metrics help SEOs identify toxic or unnatural backlinks with precision.
To identify backlinks for disavowal using Ahrefs:
Step 1: Open Site Explorer and Enter Your Domain
Navigate to Site Explorer, enter your domain, and click Search. This loads your backlink profile with detailed metrics on referring domains, anchor text, and link context.
Step 2: Filter Low-Quality or Suspicious Domains
Go to the Backlinks or Referring Domains tab and apply the following filters to identify high-risk links:
- DR (Domain Rating): Sort from low to high. Focus on DR 0–10.
- Traffic: Filter domains with zero organic traffic.
- Language: Flag domains in unrelated or foreign languages.
- Platform/Ref type: Identify forums, directories, or comment-based links.
Check for:
- Over-optimized anchors (e.g., exact-match keywords)
- Links from deindexed domains
- Multiple links from the same suspicious domain
Step 3: Manually Review Each Link
Click into suspicious referring domains and evaluate:
- Site structure and content relevance
- Link placement (sidebar, footer, or article body)
- Whether the site is part of a known link network
- Spam indicators using MozBar or third-party overlays
📌 Only include links in the disavow list after confirming they are manipulative or irrelevant.
Step 4: Build and Format Your Disavow File
Manually collect the toxic domains or URLs and compile them into a .txt file using this format:
# Disavow list – Ahrefs review (October 2025)
domain:spam-example.com
domain:expired-pbn.net
http://lowtrustdomain.com/spammy-post.html
Save it in UTF-8 encoding and ensure:
- No use of site:, wildcards, or trailing slashes
- Use domain: for domain-level disavows
- Limit full URLs to rare, page-specific cases
Step 5: Upload to Google’s Disavow Tool
Access the Google Disavow Tool and upload your finalized file.
Note: Ahrefs no longer stores disavow lists. Maintain a local version for future updates and always back up your file before changes.
Why Google Warns Against Overuse
Google advises using the Disavow Tool only in high-risk cases involving unnatural links or manual actions. It is not a general SEO maintenance tool. Overusing it can backfire and harm your search performance more than the backlinks themselves.
The Risks of Improper Disavowal Include
- Loss of legitimate link authority: Disavowing links without strong evidence can remove valuable PageRank signals. Even low-authority or foreign domains may provide real, relevant trust indicators if earned naturally.
- Disrupting natural link patterns: Google’s algorithms assess backlink profiles holistically. Removing links that appear unusual—but are actually harmless—can weaken the semantic structure and contextual relevance of your site.
- Reacting to temporary ranking drops: Not all traffic fluctuations require a disavow. Short-term dips may recover on their own. Acting without verifying a real penalty or pattern of toxic links often does more harm than good.
- Treating low-quality links as toxic by default: Low traffic, low Domain Rating (DR), or unrelated geolocation do not automatically make a link toxic. Many legitimate sites start small. Disavowing them blindly can remove future ranking potential.
Google’s guidance is clear: if there’s no manual penalty and no evidence of link manipulation, you don’t need to disavow anything.
Avoid Disavowing When
- The only issue is a sudden dip in rankings with no penalty.
- You’re relying entirely on automated “toxicity” labels without manual validation.
- The linking site is simply unfamiliar, small, or inactive—but not harmful.
Best practice is to manually verify before taking action. Review each link’s context, anchor usage, and the linking site’s content quality and purpose. If a link doesn’t violate guidelines or manipulate PageRank, it’s usually best left alone.
In most situations, the better strategy is not link removal—but building new, high-quality backlinks that strengthen your authority.
Disavow is a precise recovery tool. It should be used with caution, not as a shortcut or safety net.
Mistakes to Avoid When Disavowing Links
Disavowing backlinks is a high-impact technical process. Incorrect use can damage your SEO more than the backlinks you’re trying to avoid. To prevent this, it’s critical to follow strict criteria and avoid common missteps.
1. Disavowing Links Without Evidence of Harm
Do not disavow links just because they come from low Domain Rating (DR) sites, appear unfamiliar, or seem inactive. Many small or niche websites link naturally and are safe. Disavowing them removes healthy link equity.
2. Using Automated Tools Without Manual Review
Toxicity scores and link audits from SEO tools are helpful—but not always accurate. Always verify flagged links manually. Review site content, anchor text patterns, and the intent behind the link before making a decision.
3. Targeting Individual URLs Instead of Domains
Disavowing individual URLs from a spammy domain often misses the bigger issue. Use domain: for full coverage unless you have a clear reason to isolate a specific URL. This simplifies management and reduces future risk.
4. Incorrect File Formatting
Formatting errors can cause Google to ignore parts of your disavow file. Common issues include:
- Using site: instead of domain:
- Leaving spaces after domain:
- Adding wildcards, slashes, or unsupported symbols
- Submitting non-UTF-8 encoded files
5. Forgetting to Update After a Site Migration
Disavow files are tied to the specific property in Google Search Console. If you move from HTTP to HTTPS or change your domain, you must re-upload the disavow file under the new URL-prefix property.
6. Removing Previously Fixed Links Without Updating the File
If you successfully remove a bad link or if the linking domain improves (e.g., rebranded, cleaned-up content), you can remove it from your disavow file. Leaving unnecessary entries won’t cause harm but adds clutter and can lead to confusion in future audits.
7. Reacting Emotionally to Ranking Drops
Disavowing in panic—especially after a Google update—often leads to errors. A small dip in rankings could be algorithmic, temporary, or unrelated to backlinks. Assess carefully before acting.
8. Uploading a New File Without Preserving the Previous List
Each disavow file upload replaces the old one. If you forget to include earlier entries, you risk undoing your previous protections. Always work from your master disavow list and keep versioned backups.

FAQs About Disavowing Backlinks
What is a disavow file?
A disavow file is a plain text (.txt) document that lists domains or URLs you want Google to ignore when evaluating your backlink profile. You upload it through Google’s Disavow Tool to prevent harmful links from affecting your rankings.
Will disavowing links hurt my rankings?
Yes, if done incorrectly. Removing good or neutral backlinks can reduce trust signals and harm rankings. If done correctly—targeting only spammy or manipulative links—it can help stabilize or recover SEO performance.
How often should I disavow backlinks?
Every 3 to 6 months or after major link-building campaigns. Also consider running an audit if you notice a sudden ranking drop or receive a manual action in Google Search Console.
Can I undo a disavow?
Yes. You can remove entries from your .txt file and re-upload it, or delete the file entirely by selecting “Cancel Disavowals” in Google’s Disavow Tool. Changes will take effect gradually as Google recrawls the web.
Should I disavow links proactively?
Only in high-risk cases. If you’ve engaged in aggressive link-building, purchased links, or suspect negative SEO, a proactive disavow may be useful. Otherwise, it’s best to leave Google’s algorithms to ignore low-quality links on their own.
How do I know if a link is toxic?
Check for clear red flags: spammy anchor text, irrelevant content, auto-generated sites, PBN footprints, or domains with a high Moz Spam Score. Use tools for discovery—but always verify manually before adding to your disavow list.
