1. The Honest Truth About “Bad Links”
Let me start with something I wish someone had told me years ago: not every ugly-looking link is going to get you penalized.
I remember the first time I ran a backlink audit on a client’s site. I saw hundreds of links from random blogs in languages I couldn’t read, directories that looked like they were built in 1999, and forum profiles with usernames like “seo_guru_123.” Panic mode? Absolutely. I spent weeks emailing webmasters, begging them to remove links, and stressing over Google penalties.
Then I learned something that changed everything.
Google has gotten pretty good at ignoring garbage links on its own. According to Google’s own documentation, “Any links that are intended to manipulate rankings in Google Search results may be considered link spam” . The key word there is intended. A random spam link from a hacked site pointing to your homepage? That’s annoying, but it’s not you manipulating rankings. Google knows the difference .
Here’s what I’ve come to understand: there’s a massive difference between “spammy links you attract” and “manipulative links you build.” And that difference determines whether you’re at risk or just wasting time worrying about noise .
2. Wait—Are These Links Actually Bad, or Are SEO Tools Just Scaring Me?
Okay, let’s be real for a second.
A lot of SEO tools out there use the term “toxic backlinks” . And honestly? That term was made up by tool vendors. As Ahrefs openly admits, “Toxic backlinks’ is just a term made up by certain SEO tools to describe backlinks they think could hurt your website’s rankings based on several so-called ‘markers'” . That doesn’t mean you should ignore everything—but it does mean you need to apply some critical thinking.
Here’s what I’ve learned from auditing dozens of sites across different industries:
Links that are just “low quality” often don’t matter. Every site gets them. Spammers don’t discriminate. If you’ve been online for more than a year, you probably have links from sites you’ve never heard of, in niches you’ve never touched. Google’s algorithm is smart enough to say, “Eh, we’ll just ignore that” .
Links that are “manipulative” are what actually get you in trouble. These are links you (or someone you paid) actively pursued to game the system . Think paid links, excessive link exchanges, private blog networks—stuff that’s clearly designed to trick Google into thinking you’re more popular than you really are.
The difference? Intent. And honestly? Google is pretty good at figuring out intent .
3. The Real Types of Unnatural Links You Need to Worry About
Let’s get specific. Based on what I’ve seen and the official Google guidelines, here are the link types that actually pose a real risk:
3.1 Paid Links (The Obvious One)
If you’re paying for links that pass PageRank without using a rel="sponsored" or rel="nofollow" tag, you’re playing with fire . Google is very clear on this: “Text advertisements with links that pass SEO signals because they haven’t been identified with ‘nofollow’ or ‘sponsored'” violate their guidelines .
Real example: I once worked with a client who had bought a bunch of links from a “guest posting service.” The articles were on random sites about completely unrelated topics, but they all had exact-match anchor text like “best plumber in Chicago” linking to his HVAC site. He ended up with a manual action. It took six months to recover.
3.2 Excessive Link Exchanges
Trading links—”you link to me, I’ll link to you”—isn’t automatically bad. If it happens naturally because both sites genuinely find value in each other’s content? Fine. But when you enter into an explicit agreement to swap links for SEO purposes, you’re crossing the line .
What this looks like: You get an email that says, “Hey, let’s exchange links.” Or you see a pattern where every site linking to you has a reciprocal link back to them. That’s a pattern Google can detect .
3.3 Private Blog Networks (PBNs)
PBNs are networks of sites owned by the same person or organization, built solely to pass link juice to a central site . In theory, they look like real blogs. But in practice, they’re all connected. Same hosting, same content patterns, same linking behavior. Google’s been cracking down on these for years .
PBNs used to work really well. Now? They’re a fast track to a penalty. I’ve seen sites get hit hard by Google updates because they were leaning too heavily on PBN links .
3.4 Automated Links (Bots, Spam Comments, Forums)
Links built through automation—bots posting comments, automated forum profiles, scraped content with embedded links—are a huge red flag . Google considers “automating links at scale” to be spam .
I audited a site that had thousands of backlinks from blog comments. All of them had generic anchor text like “click here” or the exact same keyword. Every single comment was on a different blog, but they all looked identical. That’s a pattern.
3.5 Low-Quality Directories and Bookmarking Sites
Back in the early SEO days, submitting your site to every directory under the sun was standard practice. Now? Google explicitly calls out “low-quality directory or bookmark site links” as problematic .
The nuance: Not all directories are bad. If you’re a local business listed in a legitimate local directory? That’s fine. But a site that exists purely to collect links and has zero editorial standards? That’s trouble .
3.6 Keyword-Stuffed Anchor Text
I can’t stress this enough: anchor text is one of the clearest signals of unnatural links . If your link profile is full of exact-match keyword anchors like “cheap widgets” or “best SEO services,” that’s a sign you’re trying to manipulate rankings.
Natural links usually have anchor text like:
- Your brand name
- “Click here”
- “Read more”
- Generic phrases like “this article”
When I audit a site, the first thing I look at is the anchor text distribution. If it’s overwhelmingly commercial keywords, I start getting concerned .
3.7 Sitewide Links (Footer, Sidebar, Navigation)
Links in footers, sidebars, or navigation that appear on every page of a site are usually a sign of a paid arrangement . Why? Because natural links are typically contextual—placed within the content of a single page, not plastered across an entire website.
A client had a link in the footer of dozens of unrelated sites. All of them said “check out [client’s site] for great deals.” That’s a pattern that screams “paid links” .
4. Which Links Hurt vs. Which Links Just Look Ugly
To help you prioritize your cleanup efforts, here’s a breakdown based on what I’ve seen across multiple industries:
| Link Type | Risk Level | Likely Google Response | What You Should Do |
|---|---|---|---|
| Paid links (no nofollow/sponsored) | High | Manual action or algorithmic penalty | Disavow immediately if you can’t remove them |
| PBN links | High | Algorithmic penalty | Disavow—these are usually obvious to Google |
| Excessive keyword-rich anchor text | Medium-High | Algorithmic devaluation | Disavow the worst offenders; focus on building natural anchors |
| Sitewide footer/sidebar links | Medium | Could trigger manual review | Remove or disavow if they’re clearly paid |
| Link exchanges (excessive) | Medium | Devalued by algorithm | Disavow if they’re part of a formal exchange agreement |
| Spammy blog comments/forums | Low (if you didn’t build them) | Usually ignored by Google | Monitor but rarely disavow—Google ignores most of these |
| Low-quality directories | Low-Medium | Devalued by algorithm | Disavow the really bad ones; keep legitimate local listings |
| Random ugly links you didn’t build | Very Low | Automatically ignored | Do nothing—spend your energy elsewhere |
5. How to Actually Find These Links (Without Losing Your Mind)
Here’s the practical part—what I actually do when I need to clean up a site’s link profile:
Step 1: Start with Google Search Console
This is free, and it’s the most reliable source of data . Export your backlinks and look for:
- Sudden spikes in link numbers
- Domains you’ve never heard of
- Anchor text that looks unnatural
Step 2: Use a Third-Party Tool
I’ve used Ahrefs, Ubersuggest, and Majestic at various points. They all do a decent job of surfacing suspicious links. But here’s what I’ve learned: don’t blindly trust their “toxicity scores.” As Ahrefs points out, you can’t use metrics like Domain Rating alone to decide what to disavow .
Step 3: Manual Review (The Important Part)
This is where most people skip and just disavow everything their tool flags. Big mistake.
Look for these red flags when reviewing individual links:
- Unrelated niche: Is a link from a site about “toddler toys” pointing to your B2B software site? That’s a sign it might be unnatural .
- Keyword-focused anchor text: As I mentioned earlier, this is the #1 giveaway .
- Link location: Is the link in a footer, sidebar, or a page that exists solely to list links? Look for page titles or URLs containing “links,” “resources,” or “directory” .
- Content quality: Is the linking page just gibberish? Is it obviously spun content? That’s a bad sign .
6. The Disavow Debate: Should You Even Bother?
Here’s where my opinion might differ from some SEOs. I don’t think most sites need to disavow links.
Here’s why:
First, Google has said multiple times that they’re good at ignoring low-quality links . If you didn’t build those links, and they’re just random spam, Google likely already isn’t counting them against you.
Second, the disavow tool comes with risks. If you disavow the wrong links—legitimate links that are actually helping you—you could hurt your rankings .
When I DO recommend disavowing:
- You’ve received a manual action from Google for unnatural links
- You actively participated in a link scheme (paid links, PBNs, etc.) and want to clean it up
- There’s a clear pattern of manipulative links that you can’t remove manually
When I DON’T recommend disavowing:
- You just see a bunch of ugly-looking links and your tools say they’re “toxic”
- You’re feeling anxious about a Google update
- You have less than 100 questionable links
The process if you do need to disavow:
- Create a
.txtfile listing the URLs or domains you want Google to ignore .
- Use
domain:example.comfor an entire domain - Use the full URL for specific pages
- Upload it through Google Search Console’s Disavow Links tool .
- Wait—it can take weeks or months for Google to process .
7. Frequently Asked Questions
Q1: What’s the difference between a toxic link and an unnatural link?
“Toxic” is a marketing term made up by SEO tools to describe links they think could hurt you. “Unnatural” is Google’s actual term for links that violate their guidelines—links built specifically to manipulate rankings .
Q2: Will I get penalized for random spam links I didn’t build?
Usually not. Google is good at ignoring low-quality links that aren’t part of a manipulative scheme . The risk comes when you intentionally build links to game the system.
Q3: Should I disavow links with keyword-rich anchor text?
Only if they’re excessive and clearly part of a manipulative pattern. A few here and there? Not a big deal. A profile that’s 80% exact-match commercial anchors? That’s a problem .
Q4: How do I know if a link is paid?
Look for patterns: links from unrelated sites, links in footers or sidebars, keyword-stuffed anchor text, and content that’s clearly written just to host links .
Q5: What’s a private blog network (PBN)?
A group of websites owned by the same entity, built solely to pass link authority to a central site. They’re against Google’s guidelines and can lead to penalties .
Q6: Is guest posting still safe?
Yes, but only if you’re doing it right. Guest posts with natural contextual links and relevant content are fine. Guest posts that exist purely to insert keyword-rich links across dozens of random sites? That’s a problem .
Q7: How long does it take for Google to process a disavow file?
Weeks to months. There’s no instant fix . If you’re expecting immediate results, you’ll be disappointed.
Q8: What should I do if I get a manual action for unnatural links?
Remove or disavow the offending links, submit a reconsideration request, and be prepared to wait. It took a client of mine six months to recover after a manual action .
Q9: Can negative SEO attacks hurt me with bad links?
Potentially, but it’s rare. Google is typically good at ignoring spammy links, even if they’re pointed at you by a competitor . Unless the attack is massive and clearly manipulative, you probably don’t need to worry.
Q10: How often should I audit my backlink profile?
I recommend a quarterly review for most sites. If you’re in a competitive niche or actively building links, monthly is better .
