Private blog network
Also called PBN.
A set of sites owned by one person for the purpose of selling links from them.
A PBN is cheap because the audience is not real. The sites exist to link out, often built on expired domains that once had a reputation, and the economics only work at a scale that leaves a footprint: shared hosting, shared templates, the same outbound patterns, the same handful of advertisers.
The risk does not arrive gradually. When a network is identified, everything on it loses value at once — which is the opposite of how a portfolio of links is supposed to behave.
The tell before you buy is refusal: a seller who will not name the domain is protecting a margin or a footprint, and both are your problem after the invoice.
How LinkBourse handles it
Every listing names its domain, and ownership of that domain is proven before it can be sold. A marketplace where the site is anonymous is a different product.
Terms it depends on
- Verification
- Proving that the person selling a placement actually controls the property it will run on.
- Domain rating
- A third-party score for how strong a domain’s own backlink profile is, on a 0–100 log scale.
- Sponsored disclosure
- The label that tells a reader the placement was paid for — "Sponsored", "Paid partnership", "Ad".
