Backlinks are one of the most powerful ranking signals in SEO. When a trusted website links to your website, Google sees it as a vote of confidence. But what happens when bad websites start linking to you? That’s where the Disavow tool comes in.
In this guide, you’ll learn what it means to disavow backlinks, when you really need to do it, and how to do it step by step – without making mistakes that could hurt your rankings.
What Does “Disavow Backlinks” Mean?
Disavowing backlinks means telling Google to ignore specific links pointing to your website. When you disavow a link, you’re basically saying, “Hey Google, I didn’t ask for this link. Please don’t hold it against me.”
You do this through Google’s Disavow tool, which lives in Google Search Console. By uploading a simple text file, you tell Google to stop counting specific URLs or entire domains when evaluating your site’s rankings.
Do You Actually Need to Disavow Backlinks?
Here’s the honest truth – most websites never need to use the disavow tool.
Google’s algorithm, especially after the Penguin 4.0 update, has become very smart at detecting and ignoring low-quality links. If some random blog from another country scrapes your homepage 200 times and links to it, Google will most likely ignore it.
Google itself also warns users that this is an advanced feature and should only be used with caution. In fact, Google has intentionally made it difficult to find the tool in Search Console because it doesn’t want site owners to accidentally use it.
Disabling bad links can actually hurt your SEO by accidentally removing good backlinks from your profile.
When Should You Disavow Backlinks
Only consider disavowing backlinks when both of these conditions are true:
- You have a large number of clearly manipulative or toxic backlinks pointing to your site
- You have received a manual action in Google Search Console, or you have strong reason to believe that some are coming
Here are the specific situations where disavowing makes sense:
- You received a manual penalty – Google Search Console shows a warning labeled “Unnatural links on your site”
- You bought backlinks or used black-hat link building -such as private blog networks (PBN), paid link schemes, or link farms
- You are the victim of a negative SEO attack -a competitor is deliberately sending toxic links to your site to push you down
- Your traffic dropped suddenly and a backlink audit shows a spike in spammy links
Do NOT disavow when:
- You notice just a few random spammy links (Google handles these automatically)
- You are reacting emotionally to a scary-looking backlink report
- You have not yet tried to contact the website owner to remove the link manually
What Are Toxic Backlinks?
Not all bad backlinks look obviously harmful. Toxic backlinks usually come from websites that exist only to manipulate search rankings, not to provide real value to readers.
Common sources of toxic backlinks include:
- Spam directories and automated listing sites – sites that list thousands of random websites with zero editorial quality
- Link farms and private blog networks (PBNs) – networks of sites created solely to sell or trade links
- Hacked or malware-infected websites – Google marks these sites as dangerous
- Irrelevant low-authority blogs – sites completely unrelated to your niche with no real audience
- Over-optimized anchor text patterns – when too many links use the same commercial keyword as the anchor text, it looks unnatural
When these links pile up, Google may view your site as one that is trying to cheat the system. The result can be a ranking drop or a manual penalty.
How to Disavow Backlinks: Step-by-Step Guide
Step 1 – Run a Full Backlink Audit
Look for red flBefore you disavow anything, you need to know exactly what you are dealing with. Use a backlink monitoring tool like Ahrefs, SEMrush, or Google Search Console’s own link report to pull a full list of all websites linking to yours.
ags like:
- Links from sites with very low domain authority
- Sites in completely unrelated industries
- Websites marked as spam, adult, gambling, or malware
- A sudden increase in new backlinks from unknown sources
- Heavily repetitive anchor text that looks like keyword stuffing
Take your time here. Rushing into this step is one of the most common mistakes people make. Accidentally marking good links means you could be losing real ranking power.
At Santhya Infotech, we always recommend completing a thorough backlink audit before touching the Disavow tool.
Step 2 – Try to Remove Bad Links Manually First
This is a step that many people skip, but Google actually expects you to do this before using the disavow tool.
Contact the webmaster or site owner of the harmful domain. Send them a polite, clear email to remove the link or add a nofollow tag to it. Be specific – include the URL of their page and the URL of your page that the link points to.
Keep a record of all your outreach efforts. Save the emails you sent, the dates, and any responses you received. If Google ever asks for a reconsideration request, this documentation shows that you acted in good faith.
If the site owner doesn’t respond after one or two follow-ups, or if you’re dealing with hundreds of spammy domains, move on to creating a disavow file.
Step 3 – Create Your Disavow Fil
A disavow file is simply a plain text (.txt) file saved in UTF-8 format. Each line contains a specific URL or an entire domain to disavow.
A properly formatted disavow file looks like this:
# Disavow specific pages
# Disavow entire domains
domain:spammylinkfarm.com
domain:lowqualitydirectory.net
Important formatting rules:
Important formatting rules:
- Use the domain before the domain name so that it disavows all links from the entire website
- Each link or domain goes on its own separate line
- You can add comments using the # symbol at the beginning of the line (Google ignores these)
- The file must be plain text – do not use Word documents or HTML files
- Keep the file to less than 100,000 lines and less than 2MB in size
The decision to disavow an entire domain versus a single URL matters. If a domain has multiple toxic pages linking to you, disavowing the whole domain is cleaner and more efficient. If only one page on an otherwise decent site links to you harmfully, disavow just that page URL.
Step 4 – Submit the Disavow File to Google Search Console
Once your file is ready, here is how to upload it:
- Go to the Google Disavow Links Tool page (search for “Google Disavow Tool” to find direct links)
- Select your website property from the dropdown menu
- Click “Upload Disavow List”
- Select your .txt file and upload it
- Google will then process the file, which can take a few weeks to fully implement. Don’t expect overnight results – the process is gradual.
Google will then process the file, which can take a few weeks before it fully takes effect. Do not expect overnight results – the process is gradual.
Important: Uploading a new disavow file completely replaces any previous file. It doesn’t add to it. So always maintain a master disavow file and add to it over time instead of starting over every time.
Step 5 – Submit a Reconsideration Request (If You Have a Manual Penalty)
If your site has received a manual action in Google Search Console, uploading a disavow file is only part of the solution. You also need to submit a reconsideration request.
In this request, explain to Google what happened, what manipulative link building was done, what steps you took to clean it up, and what your disavow file covers. Be honest and transparent.
Google will review your request and, if satisfied, lift the manual penalty. Rankings usually improve gradually over the next few weeks.
Good Links vs. Bad Links – A Quick Reference
| Type | Good Links | Bad Links |
| Source | News sites, government, educational, high-authority blogs | Spam directories, PBNs, hacked sites |
| How They Were Earned | Organically through great content | Bought, traded, or built to manipulate |
| Anchor Text | Natural, varied | Over-optimized, repetitive keywords |
| Result | Boosts trust and rankings | Risks manual penalty and ranking drops |
Common Mistakes to Avoid When Disavowing
Disavowing too aggressively – Some site owners get scared when they see unknown links and disavow them altogether. This is dangerous. You could be removing links that are actually helping your rankings.
Not trying manual removal first – Google expects you to at least try to contact site owners before using the tool.
Forgetting to update your master file – if you submit a new disapproval file, it completely overwrites the old file. Always maintain a master file and update it over time.
Expecting instant results – The disavow process takes time. Give it a few weeks before assessing impact.
Disavowing without a penalty -If your site is healthy without manual action, using a disapproval tool is unnecessary and risky. Instead, focus on building quality links through guest posts, digital PR, and content marketing.
After Disavowing – What Comes Next?
Disavowing bad links is damage control, not a growth strategy. Once your backlink profile is clean, focus on building strong, natural links through original research, high-quality content, guest posting, and digital PR. This is what creates lasting SEO growth.
Santhya Infotech helps businesses recover from Google penalties and rebuild their backlink profiles using white-hat strategies – including guest post services, competitor backlink analysis, and ongoing backlink monitoring.
Frequently Asked Questions (FAQs)
A: Google can take a few weeks to process and apply the changes. Ranking improvements can take longer as Google recrawls your site and recalculates the signals.
A:Yes, technically you can. But Google advises against it unless you have a real reason, such as a history of black-hat link building or a negative SEO attack. Disavowing without reason can accidentally remove good links.
A: No. Disavowing does not remove the link from the other site. It simply tells Google to ignore it. The link still exists on the internet – you are simply telling Google to count it.
A: If a specific page from a domain is linking to you with a spammy link, disavow the URL. If multiple pages from the same low-quality domain are linking to you, it is more efficient to disavow the entire domain using domain:example.com.
A: Yes, but not partially. You can upload a new disavow file with the links you want to keep removed. However, the process is not instant, and there is no true “partial undo.” This is why careful review before submitting is so important.
Final Thoughts
Disavowing backlinks isn’t something most websites need to worry about every day. Google is already good at ignoring junk links. But if you’ve received a manual penalty, participated in a link scheme in the past, or been the victim of a negative SEO attack, knowing how to properly disavow them can mean the difference between recovery and continued decline.
The key is to be careful and methodical – audit first, remove manually where possible, create a clean disavow file, and give Google time to process it.
Done correctly, disavow backlinks protects your site without damaging the SEO rankings you’ve built.
