Disavow is the process of asking Google not to consider specific backlinks when determining your website’s rankings. Instead of trying to remove every unwanted backlink yourself, which often is not possible.
You can upload a text file listing the domains or URLs you want Google to ignore. This does not delete the backlinks from the web. Alternatively, it tells Google not to count them as ranking signals for your website.
For most websites, using the Google Disavow Tool is not necessary; Google is good at recognizing and ignoring many forms of link spam on its own. However, if your site has accumulated a significant number of harmful or unnatural links, disavowing them may help your SEO.

When Should You Use Disavow Links
Most website owners will never need to use the disavow tool. But there are situations where it makes sense that you should consider using disavow links, if:
- Your website receives a manual action for unnatural links.
- A backlinks audit uncovers a large number of toxic backlinks.
- Your site is targeted by a backlink spam attack.
- Your rankings suddenly drop because of harmful backlinks.
- You have already tried removing the bad links, but the website owners never responded.
Before assuming backlinks are the problem, check for other possible causes of ranking losses, including:
- Server downtime
- Website security issues or hacking
- Technical SEO errors
- A recent Google algorithm update
- Stronger competitors
A drop in rankings does not automatically mean you should disavow backlinks. Always investigate the root cause first.
Harmful Backlinks You Should Consider Disavowing
Not every suspicious backlink deserves to be disavowed. Focus on links that are clearly manipulative, spammy, or violate Google’s spam policies.
1. Links From Irrelevant Websites
A backlink should make sense within its context. If your website is about digital marketing but receives links from unrelated websites with no connection to your niches, those links may provide little or no SEO value. If they are clearly spammy, they are worth reviewing.
2. Backlinks From Low-Quality Websites
Some websites exist solely to publish spam or manipulate search rankings; common examples include websites that contain:
- Adult content
- Gambling content
- Malware
- Automatically generated pages
- This or copied content
These websites rarely provide value to users and can damage your backlink profile.
3. Automatically Generated Backlinks
Some services promise thousands of backlinks overnight using automated software. While that may sound appealing, these links are usually low quality and often violate Google’s guidelines. Large numbers of automatically generated backlinks can increase your risk of an SEO penalty.
4. Over-Optimized Anchor Text
Anchor text is the clickable text used in a hyperlink. A natural backlink profile contains a healthy mix of branded, generic, and descriptive anchor text. If hundreds of backlinks use the same keyword, Google may view those links as manipulative rather than natural.
5. Suspicious Foreign Websites
Receiving backlinks from international websites is not always a problem. Despite that, if your local business suddenly gains hundreds of backlinks from unrelated foreign-language websites with spammy content, it is worth investigating. When those links appear unnatural, you may want to disavow them.
6. Comment Spam
Comment spam is one of the oldest black-hat SEO tactics. It involves posting low-quality comments filled with promotional links across blogs and forums. These backlinks rarely provide any real value and can clutter your backlink profile.
7. Private Blog Networks (PBNs)
Private Blog Networks, sometimes called dummy blogs, are groups of websites created to pass link authority to another website. These sites often publish low-quality or duplicated content and exist only to manipulate rankings. If your backlinks come from obvious PBNs, they may belong in your disavow file.
8. Link Farms and SEO Poisoning
Link farms are networks of websites built specifically to exchange or sell backlinks. Some attackers also create spam links through hacked websites or malware, a tactic often referred to as SEO poisoning. These backlinks are typically harmful and should be reviewed carefully.
9. Sitewide Footer, Banner, or Widget Links
Links that appear across every page of another website-such as in footers, banners, or widgets- can look unnatural, especially when they use keyword-rich anchor text. If these links were created solely to manipulate rankings, consider disavowing them.
How to Identify Harmful Backlinks
Before you create a disavow file, perform a complete backlink audit. Several SEO tools can help you review your backlink profile, including:
- Google Search Console
- Ahrefs
- Semrush
- Moz
- Majestic
As you review your backlinks, look for patterns such as:
- Spammy or suspicious domains
- Irrelevant websites
- Unnatural anchor text
- Sudden spikes in backlinks
- Links from hacked or malware-infected websites.
Do not disavow links simply because a website has a low Domain Authority. Always evaluate the quality and relevance of the backlink before making a decision.

How to Disavow Links in Google
Once you have identified harmful backlinks, follow these steps.
Step 1. Create a Disavow File
Open a plain text editor like Notepad. List the domains or URLs you want Google to ignore. In most cases, it is better to disavow an entire domain instead of individual pages, especially if the website is clearly spammy. Save the file as a .txt file.
Step 2. Review Your File
Before uploading the file, double-check every entry. Disavowing high-quality backlinks by mistake can reduce your website’s authority and negatively affect your rankings. If you are unsure about a link, it is usually safer to leave it out.
Step 3. Upload the File
Often, the Google Disavow Tool uses the same Google account connected to your Google Search Console property. Select your website, upload the text file, and submit it.
Google will process your request over time as it crawls and re-evaluates the listed domains. Changes won’t happen immediately, so do not expect instant ranking improvements.
Best Practices for Using Disavow Links
Because the disavow tool directly affects your backlink profile, it is important to use it carefully. Here are a few best practices to follow:
- Perform a backlink audit before taking action.
- Contact website owners and request link removal whenever possible.
- Disavow only backlinks that are clearly harmful or manipulative.
- Monitor your backlink profile regularly.
- Treat the disavow tool as a last resort.
In many cases, Google already ignores spammy backlinks automatically. Unless your website has a manual action or a significant number of harmful links, you probably do not need to use the tool.
Quality Over Quantity
Backlinks continue to play a major role in SEO, but quality always matters more than quantity. A handful of authoritative backlinks will almost always outperform thousands of spammy ones. That is why maintaining a healthy link profile is so important.
If your website has accumulated toxic backlinks or received a manual action from Google, disavowing links can help reduce the impact of those harmful signals. Just remember that the Google Disavow Tool is not designed for routine maintenance.
Use it carefully, rely on data from a thorough backlink audit, and only disavow links when you have a clear reason to do so.
