How to Disavow Backlinks: Complete Beginner’s Guide

When you disavow a backlink, you are telling Google to ignore that link when it evaluates your site.

It does not delete the link. The link still exists on the other website. But Google stops counting it as a signal for or against your site.

Think of it like this. Imagine someone you do not know keeps associating your name with bad company. You cannot stop them from talking, but you can tell the people who matter, "That is not my association." That is what disavowing does.

Google introduced the Disavow Tool in 2012. It was meant as a last resort for webmasters dealing with link spam they could not remove on their own.

According to Google Search Central, the disavow tool is for advanced users only. Google itself states that most sites do not need to use it.

You submit a plain text file to Google Search Console, and Google processes it during future crawls.

Why Low-Quality Backlinks Can Damage SEO

Not every backlink helps you. Some links come from spammy or manipulative websites that Google already has low trust in.

When a large volume of unnatural links point to your site, Google may interpret your backlink profile as manipulated.

In serious cases, this can lead to a manual action or contribute to algorithmic ranking issues.

It is worth noting that Google's systems automatically ignore many spam backlinks without any action from you.

You only need to act when the volume is significant or when you receive a manual action notice.

Common sources of harmful referring domains include:

• Private blog networks (PBNs) built purely to manipulate link signals
• Paid link farms that sell links in bulk with no editorial value
• Foreign-language spam directories with no real content or audience
• Hacked websites that were forced to link to yours without consent
• Sites using over-optimized anchor text in an unnatural pattern

In large quantities, these links may create problems if Google interprets them as manipulative and ties that pattern back to your site.

Signs You May Need to Disavow Backlinks

Not every site needs to go through this process.

But here are signs that you might:

• You received a manual action notice in Google Search Console under Security and Manual Actions
• Your rankings dropped sharply after a Google algorithm update, and your backlink audit shows a spike in low-quality referring domains
• Your site was previously involved in paid link building or black-hat tactics
• You notice a sudden wave of spammy backlinks that look coordinated, which could point to a negative SEO attack

If any of these apply to you, run a full backlink audit first. That is always step one before you touch anything.

When You Should NOT Disavow Backlinks

Google has been clear about this. The disavow links tool is an advanced feature. Misusing it can do more harm than good.

According to Google's spam policy, they already have systems in place to detect and ignore many manipulative links.

Manual disavowing is only needed in serious cases where those systems are not enough.

Do not disavow if:

• You have a clean backlink profile with no signs of manipulation
• You are trying to remove low-DR domains out of caution without any evidence of harm
• You received a traffic drop that has nothing to do with links

I have seen sites lose good links by accident because someone disavowed too aggressively. Take your time before you file anything.

Can Negative SEO Cause Harmful Backlinks?

Yes. Negative SEO is when a competitor deliberately points large volumes of spammy backlinks at your site to try to hurt your rankings.

The good news is that Google's algorithms are fairly good at detecting and ignoring coordinated spam attacks. In most cases, you will not even notice the effect.

But in more serious situations, especially if you already have a thin or low-quality backlink profile, a sudden blast of manipulative links can cause a real problem.

If you see an unusual spike in low-quality referring domains in your backlink data, that is worth investigating. Run an audit, document what you find, and then decide if a disavow is actually needed.

Manual disavow action is only the right call when the attack is large enough that Google has not automatically filtered it out.

How to Audit Your Backlink Profile Before Disavowing

Before you touch any disavow file, you need a full picture of who is linking to you.

Start by pulling your backlink data from Google Search Console. Go to Links and check your top linking sites.

Then run an audit using a third-party tool like Ahrefs or SEMrush.

Look for:

• Links from domains with very low authority scores
• Links with over-optimized or keyword-stuffed anchor text
• Links from irrelevant or foreign-language sites
• Links from sites flagged for spam or unrelated adult content

Create a spreadsheet. Mark each link as good, neutral, or harmful. Only work with the ones you are confident are manipulative or spammy.

Best Tools to Find Spammy Backlinks

These tools will make your work easy:

Google Search Console

Free and shows all links Google has found pointing to your site. A solid starting point but lacks deep filtering options.

Ahrefs

One of the largest backlink databases available. I use it to check domain rating, spam scores, anchor text patterns, and new or lost links. Its Site Explorer is solid for backlink audits.

SEMrush

Has a built-in Backlink Audit tool that automatically flags unnatural links and lets you build your disavow file from within the platform. Very beginner-friendly.

Moz

Uses a spam score metric to help identify low-quality backlinks. Good for a second opinion when cross-checking audit results.

Majestic

Focuses on Trust Flow and Citation Flow. A large gap between the two numbers on a linking domain is a red flag worth looking into.

How to Use the Google Disavow Tool Step by Step

Follow these steps and you are good to go:

Step 1: Export Your Backlinks

Pull your full backlink list from Google Search Console and your chosen third-party tool. Export as CSV. Combine both lists into one spreadsheet and remove duplicates.

Step 2: Identify Harmful Links

Go through the list manually. I know it takes time, but it matters. Flag links that look spammy, come from irrelevant niches, use unnatural anchor text, or are from known link farms.

Do not rush this step. One wrongly flagged link can remove a valuable signal from your profile.

Step 3: Create a Backlink Disavow File

Open a plain text editor like Notepad. List each URL or domain you want to disavow. Use the domain-level format when a whole site is problematic. Use the URL format for individual bad pages.

Save the file as a .txt file with UTF-8 encoding.

Step 4: Use Correct Domain Syntax

For a full domain:domain:example.com

For a single URL:https://example.com/bad-page

You can add comments by starting a line with #. Google ignores these lines but they help you stay organized.

Step 5: Upload the Disavow File in Google Search Console

Go to the Google Disavow Tool page inside Google Search Console. Select your property. Click Disavow Links and upload your .txt file.

Google will confirm the upload. After that, it takes time for changes to take effect.

Step 6: Monitor Rankings and Link Signals

Keep an eye on your rankings after uploading. Check Google Search Console regularly. It can take several weeks before you see any real movement.

Log everything: date of upload, which links you disavowed, and what changes you notice over time.

How to Submit a Reconsideration Request

If your site received a manual action from Google, uploading a disavow file alone is not enough. You also need to submit a reconsideration request through Google Search Console.

Submit one only after:

• Completing a thorough backlink audit
• Making genuine outreach attempts to remove unnatural links yourself by contacting site owners
• Uploading your disavow file with all remaining harmful links included

What to include in your reconsideration request:

• A clear explanation of what happened and what caused the unnatural links
• Documentation of every outreach attempt, including emails sent and responses received
• A statement confirming your disavow file has been submitted and what it covers

Google typically responds within a few weeks. If your request is denied, they will usually explain why so you can fix the gaps and try again.

Keep your tone factual and honest. Google reviewers respond better to straightforward explanations than long justifications.

Correct Disavow File Format Explained

Here is what a proper backlink disavow file looks like:

# Links from spammy directories

Domain:spamsite.com

Domain:linkfarm.net

# Specific bad pages

https://badwebsite.com/links/my-site

Rules to follow:

• One entry per line
• No commas or special formatting
• File size must be under 100,000 lines and 2MB
• Use UTF-8 or 7-bit ASCII encoding

If you upload a new file later, it replaces the old one completely. Always include everything you want disavowed, not just new additions.

How Long Does a Backlink Disavow Take to Work?

There is no fixed timeline. Google processes the file during future crawls. That can take anywhere from a few weeks to a few months.

If you also submitted a manual reconsideration request, expect a response from Google within a few weeks after they review your case.

Do not expect overnight results. Be patient and keep monitoring.

Common Mistakes to Avoid When Disavowing Backlinks

• Disavowing good links by mistake. Always double-check before you list any domain.
• Uploading an incomplete file. A new file replaces the old one entirely. Always include your full list.
• Skipping the link removal step. Google recommends trying to contact site owners before using the disavow tool.
• Using the wrong file format. A poorly formatted file will not be processed correctly.
• Acting too fast after a ranking drop. In many cases, the issue has nothing to do with links.

Can Disavowing Backlinks Improve Rankings?

It depends on the situation.

If your site received a manual action due to unnatural links, successfully disavowing those links and filing a reconsideration request can lift the penalty and help rankings recover.

If it is an algorithmic issue, results may take longer and are less predictable. Google's systems weigh many signals, not just links.

Disavowing is not a fix-all. It works best when paired with strong on-page SEO, original content, and a clean linking strategy going forward.

How to Prevent Spammy Backlinks in the Future

The best move is to build a strong, natural backlink profile so you rarely need to run a disavow campaign at all.

Here is what helps:

• Run monthly or quarterly backlink audits
• Set up Google Search Console alerts for unusual link spikes
• Focus on earning links from relevant, high-authority sites in your niche
• Avoid buying links or participating in private blog networks
• Use a reputable link monitoring tool on an ongoing basis

Prevention is always easier than recovering from a penalty after the fact.

Disavow Backlinks vs Link Removal Requests

These are two different approaches, and knowing when to use each one matters.

A link removal request means contacting the website owner and asking them to delete the link. This is the preferred first step, especially when dealing with a manual action.

Using the Google Disavow Tool is what you do when you cannot get the link removed. Maybe the site owner did not respond, the site is abandoned, or the domain is a pure spam operation.

In practice, I usually try removal requests for two to three weeks. If nothing happens, I add the link to my disavow file and move on.

Keep records of all outreach attempts. If you need to file a reconsideration request, Google wants to see that you made a real effort to remove the links first.

Official Google Resources on Disavowing Links

Google has published clear guidance on when and how to use the disavow tool. You can find the full documentation at Google Search Central Disavow Documentation.

It is worth reading before you start. Google's position is that the tool is only for advanced users who have clear evidence of unnatural links causing harm.

Their spam policies also explain how their systems already handle many forms of link manipulation automatically.

Conclusion

Knowing how to disavow backlinks is a skill that can protect your site from penalties you may not have even caused.

Spammy and manipulative links can be a real problem in large volumes, but Google handles many of them automatically. You only need to step in when the situation is serious.

Always audit first, try link removal before disavowing, and follow the correct file format. Keep your records clean, especially if a reconsideration request is involved.

Pair this process with solid content and honest link building, and your site will stay on strong footing.

Frequently Asked Questions

Does disavowing a backlink remove it from the internet?

No. Disavowing tells Google to ignore the link during evaluation, but it still exists on the other website. Only the site owner can actually delete it.

How many links should I include in a disavow file?

Only include links you are confident are manipulative or harmful. Disavowing good links by mistake can remove positive signals from your profile.

Can I undo a disavow submission?

Yes. You can upload a new disavow file that excludes previously listed links, or you can delete the entire disavow file from Google Search Console.

Do I need to disavow if I never did any link building?

Probably not. If you have never used risky tactics, your backlink profile is likely clean. Only audit and act if you see clear signs of a penalty or a negative SEO attack.

What is the difference between a manual action and an algorithmic penalty?

A manual action is a direct decision made by a Google reviewer and shows up in Google Search Console. An algorithmic penalty is automatic and does not come with a direct notification.
