Zinn® Guest Posts
Features
Zinn® Guest Posts is where you buy guest posts, PBN links, high-authority links and SEO services on the Zinn Digital® marketplace. Every seller is approved by a person, every listing is checked against our content policy before it goes on sale, and your money is held until you have the work and have accepted it.

What the marketplace does for you
The parts that make buying and selling here safer than paying a stranger directly.
Order chat, kept on the record
Buyer and seller talk in a chat attached to the order. It is part of the order record, so it is evidence if something goes wrong, and messages that try to swap contact details are masked or held for review.
- Part of the order record
- Messages that swap contact details are masked or held for review
Revisions written into the package
Each package states how many revisions it includes before you buy, so "one more change" is a term of the order rather than a favour.
- The number of revisions is stated in every package
- Requested from the order page
A reminder before anything is final
Service orders are accepted automatically five days after delivery if you do nothing. We remind you before that happens, so silence never costs you a dispute.

Domain Rating measured, not claimed
Guest post listings show the site's Domain Rating from Ahrefs, read by the marketplace itself, so you can filter for high-authority sites without trusting a seller's screenshot.
- Domain Rating from Ahrefs
- Filter by a minimum Domain Rating
Domains stay private in public
Listing pages show masked domains to anonymous visitors and crawlers, so a publisher's sites are not listed in public. Signed-in buyers see the real domain before they pay.
- Anonymous visitors see a masked domain, such as site****.com
- Signed-in buyers see the full domain

Metrics measured, not declared
Trust Flow, Citation Flow, Topical Trust Flow and referring domains on link and guest post listings are measured by the marketplace from Majestic, not typed in by the seller.
- Trust Flow and Citation Flow
- Topical Trust Flow and referring domains
Host the sites you sell placements on
Publishers selling guest posts need sites that stay fast and online. Zinn Digital® hosting runs on our own servers with a CDN, DNS, TLS and daily backups included — and footprint-free hosting for networks of sites.
