So, your website’s rankings are tanking. You’re buried on page five of Google, the digital graveyard nobody visits. Why? Bad backlinks. Those pesky toxic links are like leeches, draining your site’s credibility and making Google’s algorithm side-eye you harder than a skeptical TSA agent.
Here’s the good news: you CAN clean up your backlink profile and save your site’s reputation. Let’s break down how to spot bad backlinks and how to perform a thorough backlink cleanup step by step.
Key Takeaways:
- Identify toxic backlinks using tools like Google Search Console, Ahrefs, SEMrush, and Majestic to protect your site’s SEO health.
- Remove harmful links by contacting site owners, disavowing them via Google’s Disavow Tool, or reporting violations directly to Google.
- Prevent future backlink issues by monitoring your profile regularly, conducting audits, building high-quality links, and avoiding shady link-building tactics.

What Are Bad Backlinks?
Bad backlinks are low-quality, irrelevant, or manipulative links pointing to your site. They’re usually easy to spot once you know what to look for:
- Links from spammy websites or directories
- Unrelated links (e.g., a plumbing website linking to a pet store)
- Links from hacked sites or link farms
- Paid links or links from Private Blog Networks (PBNs)
- Sites with a high spam score or a low domain authority
Google’s algorithm—especially post-Penguin updates—has a sixth sense for these kinds of links. When it detects them, your site’s reputation takes a hit. It’s like showing up to a job interview with a resume written in Comic Sans. 🚩
These types of backlinks violate Google’s guidelines and can lead to penalties, dropped rankings, or worse—Google simply ignoring your site altogether.
Some common types of bad backlinks include links from link farms, which are networks of websites created solely for link-building purposes without providing any valuable content to users.
Another example is acquiring paid links from websites that sell links to manipulate search rankings artificially. Backlinks from irrelevant directories unrelated to the website’s niche or industry are considered harmful.
Having such toxic backlinks can lead to severe consequences for a website, such as a drop in search engine rankings, reduced organic traffic, and a negative impact on user experience.
Google penalizes websites with bad backlinks through manual actions or algorithmic penalties, further decreasing their visibility in search results and potentially causing long-term damage to their online presence.

How Do Bad Backlinks Affect Your Website?
Bad backlinks are like SEO landmines—step on too many, and your website’s performance can blow up. They can wreak havoc on your SEO rankings and organic traffic and even put your site at risk of penalties from search engines like Google.
Here’s the breakdown of the damage bad backlinks can cause:
- SEO Performance Hits: Search engines may interpret toxic links as an attempt to manipulate rankings. This can lead to lower visibility, ranking drops, and reduced organic traffic.
- Risk of Penalties: Accumulating too many spammy or irrelevant links can trigger Google penalties, such as manual actions or algorithmic filters (hello, Penguin!). These penalties can tank your rankings and bury your site in the search results.
- User Trust Issues: Bad backlinks often direct visitors to irrelevant, spammy, or malicious content like phishing sites or malware. When users associate this with your site, it erodes their trust and discourages them from coming back.
In short, bad backlinks don’t just hurt your SEO—they damage your website’s credibility, trustworthiness, and long-term growth. Keeping them in check is non-negotiable.

How to Identify Bad Backlinks?
You can’t fix what you can’t see, so your first step is auditing your backlink profile. Here’s how:
1. Use a Backlink Audit Tool:
Grab a tool like Ahrefs, SEMrush, Google Search Console, or Majestic to analyze your backlinks. These tools can help you find spammy links by flagging:
- Links with high spam scores
- Low-quality domains
- Sudden backlink spikes (a red flag for spammy campaigns)
2. Watch for Red Flags:
Pay attention to links from:
- Sites with irrelevant content
- Non-English websites unrelated to your niche

How to Use Google Search Console for Backlink Analysis
Google Search Console (GSC) is a must-have tool for anyone serious about SEO. It’s Google’s own platform to help webmasters monitor their website’s performance in search results, including the backlinks pointing to their site. Beyond tracking rankings and performance, it’s also a vital resource for spotting and tackling potential link spam that may require disavowing.
1. Navigate to the ‘Links’ Section:
In GSC, head to the Links tab to uncover valuable data about your backlink profile. You can view:
- Total number of backlinks
- Referring domains linking to your site
- Your site’s most linked pages
- The anchor text commonly used to link to your content
2. Look for Red Flags:
- Unnatural link spikes: If you notice a sudden surge in backlinks, it could indicate a negative SEO attack or spam campaign.
- Foreign characters: Backlinks with odd Japanese or Chinese characters often indicate toxic links or negative SEO efforts targeting your site.
3. Check for Keywords:
Use the data to analyze what kind of keywords those linking sites are ranking for. If they’re unrelated to your industry or niche, that’s another red flag.
Manual Actions: Spotting Link Penalties
Google Search Console provides a Manual Actions report, your first stop if you suspect your site has been penalized. Google flags issues like:
- Unnatural backlinks
- Link schemes
- Paid or manipulative links
If your site is hit with a manual penalty, this report outlines the exact violation and provides steps for recovery.
Disavowing Toxic Backlinks in Google Search Console
When you’ve identified harmful backlinks dragging down your SEO performance, you can use GSC to disavow them. Here’s how:
1. Create a Disavow File:
- Gather the toxic URLs or domains you want Google to ignore.
- Format the file as a simple
.txt
file, listing domains like this:makefileCopyEditdomain:spammywebsite.com domain:badlinkfarm.net

2. Upload the File:
- Go to the Google Disavow Tool.
- Upload your disavow file and submit it.
By doing this, you’re telling Google to disregard these backlinks when assessing your site’s authority.
Pro Tips for Using GSC to Monitor Backlinks
- Regularly audit your backlinks via GSC to stay ahead of potential spammy links.
- Pay attention to anchor text—over-optimized or irrelevant keywords can signal manipulative linking practices.
- Use the Manual Actions report as an early warning system for any penalty risks.
Google Search Console isn’t just a tool—it’s your SEO surveillance system, ensuring your backlink profile stays clean and compliant.

Ahrefs: Your All-in-One Backlink Analysis Tool
Ahrefs is a powerhouse SEO tool that offers deep insights into your backlink profile, helping you uncover toxic links, assess domain ratings, and analyze spam scores. If your goal is to clean up bad backlinks, Ahrefs is your go-to tool for identifying and disavowing harmful links.
Here’s a step-by-step guide to finding and handling bad backlinks using Ahrefs:
Step 1: Analyze Your Backlink Profile in Site Explorer
1. Open Ahrefs Site Explorer.
2. Paste your website URL into the search bar and hit enter.

3. Navigate to the Backlink Profile section to see a detailed breakdown of referring domains, anchor text, and the total number of links pointing to your site.
Step 2: Check for Spammy or Toxic Keywords
1. Go to the Organic Keywords report.
2. Review the anchor texts and referring domains for red flags. Common spam indicators include:
- Keywords like “login,” “sex,” “slots,” or “casino”
- Anchor texts with gibberish or foreign characters
- Links coming from unrelated or suspicious niches

If you see a pattern of spammy or irrelevant keywords, there’s a strong chance these backlinks pass toxic link juice to your site.
Step 3: Filter Links
Ahrefs doesn’t allow you to filter out spammy domains but lets you filter the best backlinks (or exclude them, domain rating (DR), or anchor text. Use these filters to drill down on suspicious links:
1. Go to Ahrefs, click Site Explorer, and type in your domain name.
2. Now go to Backlinks in Backlink profile on the left-hand side.
3. Click on Best links. You will see a dropdown menu. Select Exclude all best links.
4. Select Dofollow and hit Show results.
5. Sort your links by DR to get the lowest-rated ones on top of the list.
6. Export the backlink report as CSV.

Step 4: Create a Disavow File
Once you’ve identified the toxic backlinks, you’ll need to compile them into a disavow file. Ahrefs simplifies this process with its built-in Disavow Tool:
1. Add the bad links or domains to your disavow list directly within Ahrefs.
2. Export the disavow file in the proper .txt
format.
How to Prevent Bad Backlinks in the Future
Preventing bad backlinks is a non-negotiable if you want a strong SEO profile and sustainable organic traffic. Think of it like regular maintenance for your car—if you don’t keep tabs on what’s happening under the hood, things can spiral out of control.
Monitor Your Backlinks Regularly
Keeping an eye on your backlink profile is the first step. Regular monitoring helps you catch shady links before they cause damage. You can choose any tool to track new backlinks and spot anything suspicious.
Set up alerts to notify you of sudden backlink spikes or odd patterns. If something looks off, you’ll know right away and can take action to protect your rankings.
Look for large spikes in the Backlinks profile in Ahrefs.
Perform Regular Link Audits
Link audits are like spring cleaning for your backlink profile—they help you find and address harmful links lurking in the background. I personally use Ahrefs, but SEMRush or Moz are just as good.
Categorize links into “keep,” “disavow,” or “remove” buckets based on their quality and relevance. Toxic links? Either disavow them or try to get them removed. A clean backlink profile keeps your site in Google’s good books.
Build High-Quality Backlinks
What is the best defense against bad backlinks? A rock-solid offense. Focus on building high-quality, niche-relevant backlinks that boost your authority. Start by creating killer content that naturally attracts links from reputable sites.
Next, put on your outreach hat and share your content with industry leaders, bloggers, or influencers. Organic, earned backlinks are always better than anything you could buy. Remember: quality over quantity wins every time.
Avoid Spammy Link-Building Tactics
Here’s the deal: shortcuts like buying links or joining link farms might seem tempting, but they’re an SEO death trap. Google is smart—its algorithms can sniff out black-hat tactics like irrelevant anchor text, hidden links, and spammy link schemes. Stick to white-hat SEO practices and earn links that actually move the needle for your rankings.
