PBN

PBN explained

A PBN, or private blog network, is a group of websites controlled by one person or company and used mainly to link to other sites to manipulate rankings. They're often built on expired domains with old link histories. Google's spam policies cover them under link spam and expired domain abuse.

How it affects trust

PBN links are often sold quietly inside cheap SEO packages or "high authority guest posts". The business paying for them may not even know. When Google detects the network, the links stop working at best, and at worst the site receives a manual action for unnatural links.

Risky habits

• Buying links because a provider says they're "safe" or "white label".
• Trusting third-party authority scores on sites with no real audience.
• Building your own network of sites to link to your business.
• Ignoring the risk because results looked good at first.

A realistic example

A dog groomer pays a low monthly fee for "SEO with backlinks". Months later she looks at Search Console's Links report and finds dozens of links from unrelated blogs with recipes, crypto news and her grooming link all on the same pages. That's a typical PBN footprint. She cancels and asks how to clean it up.

How to review yours

Look through Search Console's Links report for sites that link to you but have no obvious reason to, especially blogs with random topics and thin posts. Ask any current or previous provider exactly where links came from and whether they were paid for. Get answers in writing.
