Unnatural links aren’t new. But in 2025, they’re riskier than ever.
For years, spammy link building was one of the fastest ways to increase rankings. Marketers bought links, swapped links, and joined shady networks to climb the search engine results pages.
Some brands got away with it.
Others got hit with manual actions or algorithmic drops.
Today, Google’s Spam Policies and AI-driven updates make it nearly impossible to hide manipulative tactics. The webspam team, Search Console warnings, and advanced link analysis can spot toxic backlink patterns.
Once you’re flagged, your search rankings drop. Worse, your trust and credibility are on the line.
The problem is, many businesses still don’t know the difference between natural backlinks and manipulative link schemes.
But there’s a clear path forward. You can build a strong backlink profile, avoid penalties, and earn repeated mentions from reputable websites.
In this guide, we’ll break down everything you need to know about unnatural links in 2025 and how to protect your SEO strategy.
Highlights:
- Google’s AI and Spam Policies can now detect manipulative link schemes, which lead to penalties or search ranking drops.
- Natural backlinks build long-term authority. Links earned from reputable, relevant sites signal trust and credibility that algorithms reward.
- Content quality drives organic links. Authentic, data-driven, or experience-based content earns citations naturally.
- Repeated mentions matter more than one-offs. Consistent links from trusted publishers compound authority and drive steady organic traffic.
What are unnatural links?
Unnatural links are inbound or outbound links that violate Google Search Essentials and spam policies for Google Search. They’re manipulative, spammy, or deceptive, instead of being earned organically through ethical practices.
Types of unnatural links
Here are some examples of unnatural links that violate Google’s guidelines:
- Link schemes: PBNs (private blog networks), link farms, excessive reciprocal links.
- Automated links: Spam bots, comment sections, or forum posts generated for links.
- Irrelevant guest posting: Posting content on unrelated sites just to gain a link.
- Hidden or cloaked links: Links not visible to users but present for crawlers.
- Paid links without disclosure: Buying links to boost PageRank.
- Over-optimized anchor text: Keyword stuffing in backlinks.
Why brands shouldn’t have unnatural links
Here’s why you shouldn’t have unnatural links pointing to your website:
1. Google’s AI is more advanced
Modern algorithms analyze link intent, context, and patterns.
Even previously “safe” paid links or guest post networks can now trigger manual or algorithmic penalties.
2. Unnatural links can trigger manual actions or be discounted, which can cause steep visibility loss
Sites with spammy links risk manual actions, partial or full de-indexing, or algorithmic suppression.
3. Anchor text and link context matter
Google in 2025 evaluates and takes semantic relevance seriously. Keyword-stuffed links or unrelated anchors get flagged as manipulative.
4. Link pattern-based risks
Sudden spikes in unnatural links indicate manipulative intent.
This is easier to detect now with AI-powered pattern recognition.
5. Even historical links can hurt you
Links earned years ago from PBNs, forums, or low-quality directories may now count as toxic if the source degrades or becomes penalized.
Here’s what else you need to know about unnatural links. 👇
What’s important to know about unnatural links?
Unnatural links kill your SEO efforts.
The real problem with unnatural links isn’t solely penalties.
It’s signal dilution.
When Google sees links coming from irrelevant or manipulative sources, it may start questioning how trustworthy all of your backlinks are. So, even high-quality, earned links can be discounted if your link profile looks artificial.
Unnatural links also distort data for your own strategy.
Metrics like referral traffic, domain authority, and link velocity become noisy. So, it’s hard to even identify which efforts support growth. Strategically, you could be investing in content or partnerships that appear effective but are undermined by spammy signals elsewhere.
Think about a B2B SaaS brand participating in a “guest post network” — where dozens of unrelated blogs link back with exact-match keywords.
Initially, rankings may jump for competitive terms.
But over time, Google will detect the repeated manipulative pattern, flag the profile, and either apply an unnatural links penalty or ignore these links.
Now, the links you thought were helping become neutralized. And your genuinely earned mentions (like case studies or expert roundups) carry less weight. Because the algorithm can’t separate the signal from the noise.
That’s because it’s pivotal to avoid any tactics that might appear manipulative.
➜ Instead, focus on building links that reinforce your authority naturally. Get contextually relevant anchors and repeated mentions from sites that influence your target audience.

What’s important to know about natural links? And how to get them!
Natural links signal trust and authority to Google. Unlike unnatural links, they reinforce your credibility and demonstrate that your site is a go-to resource in your niche.
Here’s a natural mention SoFi received in a blog post on Bulkly’s website:
When high-quality domains link to you repeatedly, it’s a clear vote of confidence that your content is relevant and useful.
This is E-E-A-T and authority score building heaven.
Natural links also provide cleaner data you can use to refine your link building strategy. With a closer eye on referral traffic and engagement metrics, you’ll know which content formats, topics, and campaigns are moving the needle.
Here’s what we’ve learned about natural links and how you can earn them in an ethical way:
Authentic content earns natural links
At uSERP, we’ve consistently seen that content that’s credible, sharp, and brand-aligned gets the best link building results.
And the best part is, no outreach is required.
In an SEO Power Plays conversation with Dmitry Dragilev and Jack Lau, we talk about how
“honest, opinionated, and real-experience content” trumps keyword-stuffed guides.
Or AI fluff.
“When someone puts skin in the game — their story, their process, their belief — that’s what gets shared. That’s what people link to,” Dmitry says.
TL;DR: Skip generic blog posts and focus on creating stuff people want to cite, quote, or use to prove a point.
Look at our examples below to start planning your authentic content assets. 👇
Content assets you can create to attract natural backlinks
Start earning natural links by creating the following valuable content types:
- Content about experiments: “We tried this and here’s what happened” content.
- Controversial takes content: Sharp opinions that challenge the status quo.
- Use case content: Product use cases explained clearly with examples.
- Citation-worthy content assets: Original data, research, or stats.
- Thought leadership content: Founder or expert POVs.

➜ Create source material at scale, and watch how you’ll start to earn links passively.
Repeated natural links matter more than one-off mentions
One-off mentions don’t do much for SEO. Repeated, natural links help build authority at scale.
Here are some reasons repeated natural links are important:
- Neighborhood influence: Being cited alongside other authoritative content improves your “link neighborhood,” which increases trust.
- Anchor text diversity: Multiple links allow varied anchor text naturally. This helps boost topical relevance without over-optimization.
- Contextual evolution: Links in new or updated articles show your content stays relevant as the topic changes.
- Long-tail authority: Multiple mentions help you rank for niche queries that one-off links rarely capture.
- One-off mentions slip away: One-off mentions can vanish or lose relevance over time.
- Consistent traffic: Repeat backlinks drive steady referral traffic and support SEO.
TL;DR: Short, one-time links are nice. But repeated, evolving backlinks build authority and sustainable SEO value.
How to get repeated natural link mentions
The best way to get repeated natural link mentions is by building relationships with high-authority publishers who consistently produce quality content.
You want to pitch co-created resources, recurring expert columns, data collaborations, or joint research studies.
(Consistently provide value to these partners via unique data, actionable insights, or exclusive case studies — and they’ll gladly cite your work multiple times across different articles or updates.)
Your backlink profile is also a living asset.
➜ Track which sites are already referencing your content and identify opportunities to deepen those relationships. When you release new insights, expand existing research, or create complementary content, reach out to these sites with contextual pitches.
Instead of conducting random cold outreach, you’re using a targeted, value-driven approach that encourages repeat mentions.
More actionable tips include:
- Included branded visuals with valuable insights. Infographics, tool screenshots, and static data visuals give publishers easy, reusable assets to link back to. (Notice the one we shared above!)
- Design your content so individual sections, stats, or case studies can each stand alone as linkable assets. Publishers often reference discrete elements instead of entire pages.
- Create a content series around a single topic or framework. Publishers who link to one piece may reference other parts of the series over time.
Here’s a marketing content series publishers can easily binge and link out to:
Maximize discovery to earn more natural links
Even the most authoritative content won’t earn links if no one sees it.
Discovery is the missing piece most brands ignore. You don’t need manipulative outreach, but you do need to make sure the right people can find, reference, and reuse your content.
How to maximize content discovery to earn more natural links
Start with syndication.
Share your best assets through trusted industry newsletters, roundup sites, and niche publications that already influence your audience. Pick channels with real domain authority and editorial standards.
Once your content is in those networks, you unlock co-citation opportunities.
Here’s a quick 3-step checklist you can use:
Discovery Checklist
1. Build relationships with editors from niche publishers. They’ll reuse and cite your work repeatedly if you make their job easier.- 2. Pitch inclusion in roundups or industry newsletters with your strongest stat, framework, or takeaway.
- 3. Highlight discrete elements (charts, data points, visuals) that other sites can quote or use directly to increase co-citations.
For example, if you publish a conversion optimization report, pitch one key chart to a SaaS newsletter. From there, multiple blogs could pick it up, link to that chart, and cite the broader study. One piece of content now earns layered mentions across different contexts.
The key piece here, though, is long-term content partnerships.
You need to start thinking about how to link arms with authoritative publishers for the long haul.
Remember, that’s our speciality. We have a whole outreach team that’s trained on building valuable relationships with publishers at scale.
