Unnatural Links
Unnatural links are backlinks built primarily to manipulate search rankings — not to help users. Google's spam policies treat them as link schemes, and sites caught with them risk manual actions or algorithmic suppression. The fix is boring but effective: remove what you can, document every attempt, and disavow only the leftovers you can't control. Blind disavow files are a recipe for self-inflicted damage.

Analysis
What Are Unnatural Links?
Unnatural links are backlinks created primarily to manipulate search rankings, not to serve users. Google treats link schemes, paid links, excessive exchanges, and other manufactured patterns as spam. According to Google's spam policies, any link intended to manipulate PageRank or rankings — inbound or outbound — is a violation. Common patterns include paid placements, link exchanges, private blog networks, automated links, widget/footer abuse, and non-editorial directory submissions. The intent is what matters, not the attribute. A nofollow link can still be unnatural if it's part of a paid scheme.
Analysis
How Google Detects Unnatural Links
Google's link analysis algorithms look for patterns that don't happen naturally. The usual suspects:
- Anchor text with more than 15% exact-match commercial keywords
- Links from known PBNs or link farms
- Reciprocal link patterns that exceed a 3:1 ratio
- New links growing faster than organic traffic — a dead giveaway something is bought or manufactured
Machine learning models compare your profile to industry benchmarks. Not every low-quality link triggers a penalty. Google often ignores spammy links algorithmically, but manual actions still happen for obvious schemes. If your link profile looks like a paid advertising campaign, you're asking for trouble.
Analysis
Remediation Options for Unnatural Links
| Option | Best use | Risk | Notes |
|---|---|---|---|
| Manual removal request | First-line cleanup for links you control or can get taken down; most defensible for reconsideration requests. | Low if documented | Requires outreach and follow-up; Google expects actual cleanup when possible, not just a disavow pass. |
| Disavow file | Use when removal fails or is impractical — legacy paid links, networks you can't reach, foreign-language spam. | Medium if used too broadly | Does not delete links; tells Google to ignore specified URLs/domains. Over-disavowing removes real equity. |
| Do nothing | Only defensible when links are low-quality but not clearly manipulative, and there is no manual action. | Low immediate effort | Risky if the profile is scheme-heavy. You're gambling that Google won't notice. Some people win that bet; others get a manual action surprise. |
| New clean link building | Replacement strategy after cleanup: editorial PR, real outreach, branded anchors, relevant mentions. | Low policy risk | Slower and harder. Works only if the links are genuinely earned. No shortcuts. |
Analysis
Step-by-Step Cleanup Process
- Run a backlink audit filtering for toxic signals. Look for high link velocity, unnatural anchor text, and low domain quality.
- Prioritize removals by link velocity and anchor text. Start with the most obviously manipulative domains.
- Document at least three outreach attempts per link (screenshots, emails). Google wants to see you tried.
- Disavow remaining toxic links via Google Search Console only after removal attempts are logged.
- Build three natural links for every one you removed. Rebalance the profile with real editorial content.
Successful reconsideration cases in my experience averaged around 70% link removal before filing the request. Google is not impressed by a disavow file that covers 90% of your profile.
Analysis
When to Disavow vs Remove vs Ignore
Disavow: Links from penalized sites, foreign language spam, hacked pages, or networks you can't contact.
Remove: Paid links, PBNs, guest post exchanges, any link you can honestly ask a site owner to take down.
Ignore: Low-quality but non-manipulative directory/bookmark links. If they're not clearly part of a scheme, let them be.
Never disavow more than 60% of your backlinks without rebuilding. Over-disavowing legitimate links removes real equity and makes recovery harder. I've seen sites drop 30% of their organic traffic because someone disavowed an entire domain out of fear.
Analysis
Risks of Ignoring Unnatural Links
- Google manual actions for unnatural links can suppress rankings until the issue is cleaned up. That's weeks or months of lost traffic.
- Money spent on paid posts, PBNs, link exchanges, and automated links is often wasted because Google may ignore or discount the links anyway. You're paying for nothing.
- Over-disavowing legitimate links can remove real equity and make recovery harder. Don't be trigger-happy.
- Ignoring outbound unnatural links creates a site-level spam risk if your site is selling or participating in manipulative linking.
- Relying on exact-match anchor manipulation increases footprint visibility and detection risk. It's the easiest signal for Google to spot.
Answers
Frequently asked questions
Are all bad backlinks unnatural links?
No. Most bad backlinks are just low-quality or irrelevant. Unnatural links are the subset created mainly to manipulate rankings — paid, exchanged, or manufactured. A bad link from a spammy comment section is not the same as a paid link from a PBN.
Does Google always penalize unnatural links?
No. Google can algorithmically ignore spammy links rather than penalize them. The real risk is when the pattern is obvious enough to trigger a manual action. Most sites with a few bad links never get hit. It's the consistent, aggressive schemes that get caught.
Should I disavow every spammy backlink?
No. Disavow only links you believe are manipulative and that you cannot remove. Broad disavow files can delete legitimate equity and make things worse. I've seen sites lose rankings because someone disavowed a whole domain that had a few good links mixed in with the bad.
What is the first step in fixing unnatural links?
Classify the links. Separate the obviously manipulative from the merely low-quality. Then request removals from the linking sites and keep records of all outreach. Use disavow only for the leftovers you can't remove.
Are nofollow and UGC links unnatural?
Not by default. Nofollow and UGC are attributes meant to describe or limit trust. The issue is whether the link exists mainly to manipulate rankings. A paid nofollow link is still a violation.
Do expired domain redirects count as unnatural links?
Yes, if the redirect exists solely to pass equity. Google's 2023 spam update specifically targets purchased expired domains with 301 redirects. Using an expired domain for its link juice is a clear scheme.
Can AI-generated content links be unnatural?
Only if placed in manipulative contexts — PBNs, paid placements, automated link farms. Editorially placed AI content links don't inherently violate guidelines. The content source matters less than the intent behind the link.
