What is a PBN, and what should you do if one links to you?

If you've ever looked into buying backlinks, you've probably been offered PBN links.

"High DR guest posts, permanent, $40 each." The sites look decent at first glance. The authority numbers look great.

Here's what's usually behind those offers, and why I don't buy them.

What a PBN is

PBN stands for private blog network.

Someone buys a pile of expired domains that used to belong to real businesses or blogs. Those old domains still have links pointing at them from their past life, so they come with a high DR or authority score. The owner puts a simple blog on each one, publishes thin articles, and sells links from them.

The point of the network isn't readers. It's passing link value to whoever pays.

That's the key difference from a real site. A real blog links to you because the link helps its readers. A PBN links to you because you paid, or because it's padding out a fake-looking site with links to real ones.

How to spot one

PBN sites tend to share the same tells:

• High authority, almost no traffic. A DR 50 site that gets no visits from Google is a red flag. Real sites with that much authority usually rank for something.
• A strange history. The domain used to be a dentist's office, and now it's a general "lifestyle" blog. Old pages from its previous life still have links pointing at them.
• Everything and nothing. Articles about crypto, pets, home loans and travel, all on the same site, all about the same length.
• Outbound links everywhere. Nearly every post links out to a different business, often with keyword anchor text.
• No real people. No author bios that check out, no social accounts, no comments.

That's what DR Buddy's Link Health Check looks for when you paste in a list of sites someone is offering you. It flags sites whose traffic has fallen while their authority stayed high, sites with high spam scores, and sites that barely rank for anything. A real site rarely trips those checks. A PBN often trips several.

Why buying PBN links is risky

Google's spam policies list buying or selling links that pass ranking credit as link spam. That includes paid guest posts with followed links and low-value content created mainly to pass links. A PBN is basically both of those at scale.

Two things can happen:

1. The links just stop counting. Google's link spam systems are built to neutralize unnatural links automatically. You paid for something that does nothing.
2. A manual action. If it's a big part of your link profile, a reviewer can flag your site for unnatural links. Then you're cleaning up, and that's when the disavow tool comes in.

Either way, the money's gone. And PBN links often vanish when the network gets caught or the owner stops paying for the domains.

What if a PBN links to you and you didn't ask?

This is the question I get most, and the answer is calm: usually nothing.

Sites in these networks link to well-known and random real sites to look more natural. Your site might be one of them. You didn't pay, you didn't ask, and Google has no reason to hold it against you. The same systems that neutralize paid links neutralize these too.

You don't need to disavow them. In DR Buddy, ignore them in your backlink scan and they'll stay out of your way.

The only time to act is the same as with any junk link: if you, or someone working for you, bought them. Then read Should you disavow backlinks?

What to do instead

Real links come from real sites with real readers. A guest post on a small blog that actually gets traffic is worth more than a "DR 60" PBN post that nobody reads.

Before you pay for any link, run the site through Link Health Check. It takes a minute, and it's the cheapest way I know to avoid paying for a link that does nothing.
