Link Building Marketplaces, Guest Post Platforms & SEO Carts

Link building marketplaces: carts, media catalogs, and rental networks

Last reviewed: 15 July 2026

Research directory of ~207 link building marketplace platforms (guest-post carts, media catalogs, regional specialists, rental networks, freelance gig platforms, and managed hybrids). A listing is research, not an endorsement — and this directory is not RankSupply’s fulfillment inventory (~100k publishers we can place through as a white-label desk). Profiles with a full write-up carry a verdict and a last-checked date; the rest of the grid is a filterable index. Labels: Researched, Verified profile, Tested by RankSupply, or Community reviewed. Verdicts run from Recommended to Not recommended. Marketplace methodology →

How to use this directory

A map of marketplace models — not a price list

A link-building marketplace is a platform where a buyer (or an agency acting for a client) pays a third party to place content or a link on a publisher site. That sentence covers guest-post carts, sponsored-news catalogs, insertion networks, rental-credit systems, and managed hybrids. It does not mean those products are interchangeable. The failure mode is treating every login as “a place to buy links.”

RankSupply is a white-label fulfillment desk, not a marketplace. This hub exists so agencies can see how the platforms they already hear about actually differ before they add another vendor — or before they hand the brief to us. A card in the grid means the company is in the database. It is not a quality warranty, a cheapest-marketplace claim, or a RankSupply test unless the profile says Tested by RankSupply.

Six marketplace models that are not the same product

FIG. 01 — A guest-post cart, a media desk, and a rental network solve different jobs.

FIG. 01 — RankSupply files platforms by how they actually sell. A listing is research, not a recommendation. Policy: marketplace methodology.

How the six models differ in practice

Guest-post carts (Adsy, Collaborator, iCopify) sell a new article on a site the publisher listed. You pick a domain, submit or buy copy, and wait for an editor. Media / PR catalogs (PRNEWS.IO, Getfluence, Medialister) sell sponsored coverage on news and magazine titles. Follow attributes and “Google News” status vary by outlet and are not a RankSupply promise. Regional specialists (HULC for Benelux, Linkhouse and WhitePress for CEE/EU) are useful when the language and the publisher set are the brief.

Rental and insertion networks (Serpzilla) spend credits on existing pages or recurring links. That is a different risk and a different reporting story than a new URL. Managed hybrids (BuildALink) take a brief as well as a cart. Buyer-only catalogs (SearchEye on this record) let agencies shop inventory without a confirmed open publisher counter. If you need to list a site, that distinction matters.

The same research set also includes PRWiz (a cart that publishes per-listing link-validity windows and publisher payout terms), ReputePost (a smaller cart with an explicit white-label tier), and LinksManagement (an older automated shop that still sorts on DA bands). Those three are not synonyms of Adsy. The filterable grid below is the rest of the database, including limited-research listings and platforms our research advises against, which stay noindex.

Reviewed is not Tested

Three evidence classes. None of them is a numeric quality score.

FIG. 02 — A Reviewed timestamp means we read the public record. Tested means we placed an order. Community data is a moderated first-hand account. Policy: marketplace methodology.

How to read a RankSupply profile

Every substantial profile is supposed to cover the same research questions: research status, buyer workflow, publisher workflow, placement types, regions and languages, pricing model, quality controls, strengths, limitations, best fit, Reviewed vs Tested, community reviews, alternatives, FAQ, and last-checked date. The answers should not be synonyms. If two pages only differ by the brand name, the write-up failed.

Claims on these pages are source-backed from the platform’s public site, help center, or directory fields we recorded. Catalog sizes (“100,000 media,” “24,000 publishers”) are the vendor’s marketing unless we say we counted them. We have not. Seller payout terms on file are directory research, not a live contract. RankSupply does not operate these platforms.

Self-serve versus a fulfillment desk

Keep the login when you already know the cart, you will inspect every URL, and you will own replacements. Hand the campaign to RankSupply when the agency needs one unbranded report across guest posts, niche edits, and digital PR — and does not want five marketplace invoices in the client folder. Existing side-by-sides live on compare. How fees sit next to managed pricing: link building costs.

What this directory will not do

Fake ratings like 4.8/5 or an invented Intelligence Score
Declare a cheapest marketplace without transaction data
Treat vendor catalog sizes as RankSupply-verified counts
Mark a profile Tested because we read the marketing site
Name any marketplace as a RankSupply fulfillment source

Link building marketplace FAQ

Is every marketplace in this directory recommended?

No. A listing means the company is in the RankSupply database. A recommendation requires a RankSupply verdict of Recommended and enough first-hand evidence to stand behind it.

What is the difference between Reviewed and Tested?

Reviewed by RankSupply is an editorial timestamp on a public record. Tested by RankSupply means we placed an order or ran a documented fulfillment test. They are not the same badge.

Why are most marketplace profiles noindex?

Thin profiles stay in the database so the set is complete. They stay noindex until the page has a substantial write-up, RankSupply testing, or useful community reviews.

Do you publish marketplace prices or inventory counts?

Not as verified RankSupply figures. Platforms publish their own catalog sizes and rate cards. Those are marketing claims until we have order data. Price intelligence fields stay empty on purpose.

When should an agency self-serve a marketplace instead of using RankSupply?

Self-serve when you already have the login, the vetting time, and the appetite to own replacements. Use RankSupply when you want one white-label desk across publishers, content, live URLs, and reporting.

A map of the marketplace stack — not a price list

Queries like “guest post marketplaces,” “backlink marketplaces,” “SEO marketplaces,” and “link building platforms” all belong here. We are not spinning a /guides/ clone for each synonym. Agencies do not lose campaigns because they cannot find “a marketplace.” They lose them when they juggle five logins, mixed follow labels, and publisher quality they never inspected. This directory maps guest-post carts, PR desks, insertion networks, managed services, publisher counters, and aggregators — before you add another vendor.

RankSupply is a white-label fulfillment desk, not a marketplace. We list platforms we and the market actually encounter. Thin profiles are live so the database is complete, but they stay noindex until the page has a substantial write-up, RankSupply testing, or useful community reviews. That is how we launch 190+ URLs without asking Google to rank 190 identical stubs.

Price intelligence is not here yet. We do not have enough reliable marketplace order data to publish lowest/median prices or a RankSupply Intelligence Score. Those fields exist on every record and stay empty on purpose. When we have samples, they will appear under Market Intelligence — not as a 4.8/5 badge we made up this week. How marketplace fees sit next to managed and white-label pricing: link building costs.

Featured profiles (the first set people actually search) are indexable. Everyone else can still be opened, reviewed, and claimed. As reviews clear moderation, those pages can move from noindex to index without rebuilding the site.
