What Is a PBN? Private Blog Networks Explained by a PBN Host

At a glance

• A PBN (private blog network) is a group of blogs on domains with existing authority, hosted on different servers and IPs, built to give the owner’s money site links that look natural.
• Most PBN blogs sit on expired, closeout or auction domains that still have backlinks from their previous life.
• A network is private when only its owner links from it. Once anyone can buy a link on it, it is a public network.
• SEOs use PBNs to control where links come from, which anchor text they use and how relevant the linking site is.
• PBNs break Google’s guidelines, which in our view makes them grey hat, the same as buying links, outreach and guest posts.

In SEO, PBN stands for private blog network. (In aviation it means Performance-Based Navigation, which is a different subject.) “Private” refers to who controls the network, not to password-protected personal blogs.

We’ve hosted over 100,000 PBN sites since 2014, so this explanation comes from the host’s side.

How a PBN works

Links from other sites are one of the signals search engines use to rank pages. A new domain has no links, so a PBN starts with domains that already have them.

The guide’s example: your client is a plumber in your city. You find a domain that once belonged to a different plumber, who was featured as a local businessman in a few newspapers, which brought his site plenty of links. He retired and let the domain expire. You register it and build a new plumbing blog on it. Most of the links to the domain are still live, so the new blog keeps much of the authority the old owner built. A post on that blog then links to your client’s site.

In four steps:

1. A domain with backlinks expires or goes to auction.
2. You buy it, and the backlinks still point to it.
3. You put a new blog on it, ideally restoring the old pages that had links.
4. The blog links to your money site and passes some of that authority on.

Repeat that across several domains, each hosted separately, and you have a network.

PBN sites, PBN links and PBN link building

The terms get mixed up, so here they are side by side:

Term	Meaning
PBN	The whole network: all the blogs one owner controls.
PBN site (PBN blog)	One blog in the network.
Money site	The site the network links to, the one that earns.
PBN link	A link from a PBN site to a money site, usually inside a post.
PBN link building	The process of buying domains, building blogs on them, hosting them separately and linking from them.

A network of 10 blogs gives you 10 linking domains. Each blog can link to several pages, but it is still one referring domain to the money site.

PBN link building in brief: find domains with clean backlinks, host each blog on a different server and IP, restore and add content, test each blog, then link. The full process is in how to build a PBN.

PBN blogs should not only link to your money site. A blog that links to nothing but your sites is easy to spot. Each one should also link to other small niche sites that don’t compete with you.

Private vs public blog networks

This is the distinction most definitions skip.

A private network is one where only the owner places links. Nobody else knows which blogs belong to it, and nothing about the blogs ties them together.

A public network sells links. Our guide puts it simply: “If anyone can buy a link, those are coming from public blog networks.” Public networks are much easier for Google to find, because anyone, including Google, can buy a link and see the other blogs and clients. Most “PBN link” offers you see for sale are placements on public networks.

That’s why our stance is to build your own network and never sell links on it, not even to friends. If you’re considering buying links instead, see buying PBN links.

What a PBN is built on

Domains with history come from four places:

Source	What it is	Trade-off
Expired (dropped) domains	Domains nobody renewed, now free to register at a normal price	Cheap, but good ones are now very hard to find
Closeout domains	Expired domains the registrar sells after the auction, before they drop	Often the best value when you find them
Auction domains	Expired domains sold to the highest bidder	Easier to find, can be expensive
Existing blogs	Live sites whose owners lost interest and will sell	Hard to find, and takes your own research

Tools like SEO Domain Finder list auction and closeout domains so you can filter by metrics. For what to do with a domain once you have it, see expired domains for SEO.

Why SEOs still use PBNs

Control. When you own the blog, you decide where the link points, which anchor text it uses and how relevant the linking site is. Every other link-building method leaves those decisions to another site’s owner.

Content no longer separates pages. Our guide’s view is that first-page content looks more and more alike, because everyone writes with the same content tools. When content is equal, links decide the order, and in very competitive niches your competitors are using PBNs.

Some niches barely get links any other way. Local services are the classic example: it is hard to get anyone to link to a plumber’s website.

Do PBNs still work? Yes. As long as search engines count links, a well-built network moves rankings. In our experience as a host, plenty of SEOs who publicly recommend other methods run networks of their own.

Are PBNs black hat?

No, in our view. Black hat means hacking or exploiting other people’s websites. A PBN is your own property and affects nobody else’s site.

PBNs are against Google’s guidelines, which makes them grey hat. So is most link building. Google’s spam policies define link spam as “the practice of creating links to or from a site primarily for the purpose of manipulating search rankings,” and the examples include buying or selling links and “links with optimized anchor text in articles, guest posts, or press releases distributed on other sites” (Google Search Central, fetched 2026-10-28).

That covers the “white hat” methods as well. In practice, any link you build on purpose to rank a page is against the rules. Google’s guidelines serve Google, and they don’t make one method ethical and another not. For the actual black hat tactics, see black hat link building.

The risks

There are three, and how you build the network decides how big each one is:

• Links get ignored. If a blog looks unnatural, its links may simply stop counting.
• Blogs get deindexed. If Google ties blogs to each other through shared footprints, it can drop them from the index, and their links count for nothing. Our guide traces the big wave to the end of 2014.
• The money site gets penalized. Google’s spam policies say violating sites “may rank lower in results or not appear in results at all” (fetched 2026-10-28). This mostly happens with public networks.

Footprints are what turn the risk from small to large. See PBN footprints, and for the full risk picture, are PBNs safe.

Who should build one

A PBN makes sense if you have a money site in a niche where links decide rankings, a budget for domains and time to spend on the network every month. Agencies and owners of several sites get more out of each blog, because one network can support all of them.

It isn’t a beginner method. If you’re just starting out, put your effort into the money site first.

The guide’s starting point is a network of 10 blogs for a site in a niche that isn’t too competitive. Plan on US$500 to US$2,500 in domains, spread over a few months, plus hosting.

Where Easy Blog Networks fits

FAQ

Is a PBN illegal?

No. It is against Google’s guidelines, not the law.

How many sites are in a PBN?

Any number. Our guide suggests starting with 10 blogs and adding from there.

Is a PBN the same as a link farm?

No. A link farm is a set of pages that exist to link to each other or to anyone, usually with no real content. A PBN is a set of separate blogs that look like ordinary sites. More in what are link farms.

What are PBN blog posts?

Posts on PBN blogs. Some carry links to the money site, and the rest keep the blog looking like a normal site. Many owners now write them with AI tools, and Easy Blog Networks can post them on a schedule with your own OpenAI API key.
