Private Blog Networks (PBNs): What They Are & Whether They Actually Work
What Is a PBN?
A private blog network (PBN) is a collection of websites created solely to link to another site in order to boost its Google rankings. The goal is to artificially increase that site’s authority in the eyes of search engines.
SEOs build PBNs by launching new websites or purchasing expired domains that already have authority. They then place links from those sites to the website they want to rank higher.
Those who rely on PBNs do so to maintain complete control over their link building.
In simple terms:
Instead of naturally earning backlinks, a PBN allows you to add links to your site whenever you choose, using the exact anchor text you prefer, and pointing to any page you want to strengthen.
It may seem appealing.
But it’s not.
Using PBNs for SEO directly violates Google’s Webmaster Quality Guidelines and can lead to serious penalties.
Yet they’re still discussed and used. Why?
Let’s explore.
PBNs Break Google’s Webmaster Quality Guidelines
We strongly advise against using private blog networks as a link building strategy.
Google’s link spam policy clearly states:
“Any links that are intended to manipulate rankings in Google Search results may be considered link spam. This includes any behavior that manipulates links to your site or outgoing links from your site.”
PBNs clearly fall under this definition.
These links are created to influence search results. They aren’t earned naturally—they’re placed intentionally to impact rankings.
PBN sites don’t provide genuine value. Their purpose is simply to game the algorithm.
The right way to build strong backlinks is by producing original, valuable content.
High-quality content naturally attracts links because people genuinely find it useful.
In fact, legitimate websites usually carry far more authority than low-quality PBN sites.
PBN links aren’t editorial endorsements earned through merit.
They’re artificial attempts to influence rankings—and they don’t deliver lasting results.
To see whether a website has backlinks from PBNs, you can use Semrush’s Backlinks tool. Enter the domain and analyze it.
Then navigate to the “Network Graph” tab to view a visual breakdown of its backlink profile.
If red nodes appear in the graph, it may indicate the use of PBNs and a violation of Google’s policies.
The Risks of Using Private Blog Networks
Since PBN links go against Google’s guidelines, what could happen?
There are two main possibilities:
1. Your Website Gets Penalized or Drops in Rankings
If manipulative link building becomes excessive, Google may issue a manual action against your site.
This can result in lower rankings—or even complete removal from search results.
If this occurs, you’ll receive a notification inside the “Manual Actions” section of Google Search Console.
To recover, you must resolve the issue by removing problematic links or submitting a disavow file, followed by a reconsideration request.
Even if the request is approved, your rankings may not fully recover. The most reliable long-term strategy is to focus on producing useful, relevant content.
Pro tip: Only use the disavow tool if you’ve received an “unnatural link” manual action or are confident harmful links exist. Disavowing links can affect rankings, so proceed carefully and follow Google’s guidance closely.
2. Google Ignores the Links
If Google’s algorithm determines that a backlink is unnatural, it may simply ignore it.
That means the link won’t influence your rankings—positively or negatively.
Google’s John Mueller has confirmed that links unlikely to occur naturally are often ignored.
Over the years, SEOs have submitted countless disavow files, helping Google better identify manipulative link sources.
If the links have no impact, then the time and money spent building them are wasted.
No one wants to invest resources in something that provides zero return.
Why Do Some People Still Use PBNs?
Considering the risks, why are PBNs still used?
There are two primary reasons:
1. Earning Links Is Challenging and Uncertain
Securing high-quality backlinks takes time, and success isn’t guaranteed.
Effective link building methods include:
- Email outreach
- Digital PR
- Broken link building
- Link reclamation
- Resource link building
- And more
All of these involve contacting journalists, bloggers, or site owners and persuading them to link to your content.
The goal is to increase visibility and hope they find your content valuable enough to reference.
But outcomes can’t be predicted. Even strong campaigns can’t promise a fixed number of links each month.
A PBN may appear to offer greater control and predictability—but it comes with significant risk. Earning quality backlinks is still the better approach.
2. Control Over Anchor Text
Anchor text is the clickable text within a hyperlink. Relevant anchor text helps Google understand what a linked page is about.
Because of this, some turn to PBNs. Many PBN owners allow you to select your preferred anchor text for each backlink.
When links are earned naturally, journalists and webmasters may use anchor text such as:
- “Click here”
- The article title
- A plain URL
- A brand name
However, many SEOs prefer keyword-rich anchor text that clearly signals page relevance.
Through outreach, controlling anchor text is difficult. With PBNs, it’s easy—which is why some are tempted to use them.
Common Myths About PBNs
Despite the dangers, misunderstandings about PBNs remain common. Let’s clarify four myths.
Myth 1: PBN Links Don’t Help Rankings
Although PBN links break Google’s rules, they can temporarily improve rankings.
However, the boost rarely lasts.
If Google detects manipulative behavior—through its algorithm or a manual review—your site’s visibility can drop sharply.
The risk of losing rankings outweighs any short-term gain.
Myth 2: Google Easily Identifies Every PBN
Google looks for patterns, or “footprints,” that suggest a network built solely for links. These may include:
- Shared IP addresses
- The same hosting provider
- Domains purchased from auctions
- Blocking third-party SEO tools
- And similar signals
However, those who build PBNs often try to hide these footprints.
Still, Google continues to improve at identifying low-quality links—regardless of their source.
Even if a PBN avoids penalties, its links may simply be ignored.
That means wasted effort and expense. Low-quality link schemes rarely succeed long term.
Myth 3: All Paid Links Come from PBNs
While PBNs often involve paid links, not every paid link comes from a PBN.
Many bloggers openly sell sponsored posts. But that doesn’t automatically make them part of a network.
That said, paying for links typically violates Google’s guidelines—whether or not a PBN is involved.
Myth 4: Any Group of Interlinked Sites Is a PBN
It’s common for businesses to own multiple websites and link them together.
These links are usually natural and don’t automatically form a PBN.
Companies often link related sites in their footer so visitors can discover other properties they own.
There’s generally no issue with this—provided the links aren’t used to manipulate rankings.
A network only becomes a PBN when its primary purpose is to create links solely to influence search results.
What If Your Site Has PBN Links?
If you suspect your site has links from a PBN or other low-quality sources, it’s wise to investigate.
Use Semrush’s Backlink Audit tool to locate potentially harmful links. Enter your domain and set up a project.
In the “Audit” section, you’ll see possible link networks flagged.
Click “Review backlinks” to view suspicious links, which may originate from spam pages, comment sections, PBNs, or link directories.
The report includes details such as source URL, target URL, anchor text, authority score, and toxicity score.
Google generally recommends ignoring toxic links.
If you believe a link is damaging your site, you can contact the site owner and politely request removal.
Disavowing links is also an option—but it carries risk.
Only consider disavowing if you’ve received a manual action or strongly suspect one is imminent due to purchased links.
If you proceed, select the backlinks you want to disavow, and the tool will generate a file for submission to Google’s disavow tool.
Again, exercise extreme caution when disavowing.
The Right Way to Build Links
We do not recommend using PBNs as a link building strategy. The risks outweigh any potential short-term benefit.
Instead, focus on ethical, transparent methods such as outreach, digital PR, broken link building, and other legitimate strategies.
It requires consistent effort—but it’s the safest and most sustainable way to earn high-quality backlinks for your website.
