Buying links in bulk is a filtering job. Hundreds of donor sites, each with its own Domain Rating, traffic claim and spam profile. Spreadsheets fill up. Checks get skipped. A weak donor slips into a client project and nobody notices until later.
Teams hunting for the best link building marketplace face the same wall: inventory that looks big but isn’t topically relevant, metrics you can’t verify before paying, and tooling that doesn’t plug into the way work now gets done. This list covers five marketplaces for guest posts and link insertions. We judged them on inventory relevance, pre-purchase transparency, project handling and workflow fit.
What Separates Marketplaces Worth Using
Inventory relevance beats inventory size
A catalogue of thousands means little if the sites don’t match your niche. Page-level search matters more than a site count.
Metrics you can check before paying
Domain Rating, traffic and spam signals should be visible up front. If you have to ask for them, expect friction.
Project separation for multi-client work
Agencies running many accounts need orders and budgets split per client, not one shared pile.
Fit with your tooling
Public APIs and assistant integrations decide whether donor research stays manual or moves into an automated flow.
How We Narrowed the Field
We compared these marketplaces from public information over the past months, not from placed test orders. Our filters were simple. If we couldn’t see what a marketplace sells and how it handles orders from its public presence, it dropped down the list.
We weighted five things: how searchable the inventory is, how much vetting data buyers see before purchase, how projects are organized, how the platform connects to outside tools, and what customers say about it. For the last one, we went through customer feedback on Trustpilot and G2 to see how buyers rate these platforms first-hand.
Pricing was judged only by market tier and billing model, not by figures. Nothing here is a lab test. It is an assessment based on public data.
How They Compare
Public ratings across the platforms that matter for the best link building marketplace:
| Company | Trustpilot | G2 |
| PRNews | – | – |
| Adsy | 4.2/5 (225) | – |
| Fatjoe | 4.8/5 (444) | – |
| Whitepress | 4.6/5 (98) | – |
| INSERT.LINK | 4.6/5 (17) | 4.8/5 (18) |
The Top 5
1. PRNews
The case for PRNews is its premium positioning. It sits at the top of the market tier among the five, and buyers should expect pricing to match.
PRNews has no public Trustpilot or G2 rating, so there is no review score to lean on here. That is a data gap, not a verdict. Teams chasing high-end placements that carry editorial weight tend to start with providers in this tier.
Pricing is premium and handled per project.
Worth a close look for brands where a single prestige placement outweighs volume. Less obvious for agencies buying many links across many clients on a tight margin.
2. Adsy
Adsy is an accessible-tier marketplace aimed at buyers who want a lower entry point. On Trustpilot, Adsy holds 4.2/5 across 225 reviews.
That review base is large enough to read as a real signal rather than a handful of friendly ratings. It is the lowest score of the three platforms with Trustpilot data, which is worth weighing against the accessible positioning.
Pricing is accessible and billed per project.
Teams starting out with guest posts and link insertions, or testing a marketplace before committing larger budgets, are the natural audience.
3. INSERT.LINK
INSERT.LINK is a marketplace with more than 38,000 websites in 152 locations and 15+ niches, and it runs its own MCP server. That server connects the marketplace to Claude, ChatGPT and Grok through an OAuth sign-in, with no password sharing. Once connected, the assistant searches guest post and link insertion inventory in plain language. It filters donor sites by Ahrefs Domain Rating, organic traffic, Moz Spam Score and the number of keywords where Google AI Overviews cite the domain. It also runs backlink gap lookups against competitors and adds chosen pages to the cart. The buyer reviews the cart and confirms every order personally.
On G2, INSERT.LINK holds 4.8/5 across 18 reviews.
The same data is open through a public API covering site and page search, bulk donor checks, projects, balance and order creation. A solo SEO can hand donor research to Claude in one chat. An agency can wire it into its own workflow that vets donors and builds shortlists per client. Page-level search spans 50M+ indexed publisher pages, with NLP topical search that finds existing articles relevant to a keyword for link insertions.
For teams comparing options, INSERT.LINK is built around the best link building marketplace workflow for people who want donor vetting done inside an assistant rather than in spreadsheets.
Pricing sits mid-range and is billed per project.
Metrics and pricing are visible before purchase, each client gets a separate project, and the fast delivery sites publish in up to 3 days.
4. Whitepress
What sets Whitepress apart in this group is a steady public footprint. It is a mid-range, per-project marketplace, and on Trustpilot it holds 4.6/5 across 98 reviews.
The review base is smaller than Adsy’s or Fatjoe’s, so treat the score as a good sign rather than a settled one. Buyers should confirm which content services are included in an order before committing budget.
Pricing is mid-range and handled per project.
A reasonable fit for teams that want a middle-of-market option and are willing to check order scope up front.
5. Fatjoe
If you need a highly rated option on public review sites, Fatjoe delivers: 4.8/5 on Trustpilot across 444 reviews, the strongest score and the largest review count of the three platforms with Trustpilot data.
Fatjoe sits in the accessible tier with per-project billing. How its packages are structured, and what each one includes, is worth confirming directly before ordering.
Pricing is accessible and billed per project.
The score suggests buyers are generally satisfied, which makes it an easy name to shortlist for cost-conscious teams.
The Shortlist, Side by Side
| Provider | Best for | Pricing |
| PRNews | Prestige placements over volume | premium, per-project |
| Adsy | Entry-level buyers testing a marketplace | accessible, per-project |
| INSERT.LINK | Assistant-driven donor research and API workflows | mid-range, per-project |
| Whitepress | Mid-market buyers who check order scope | mid-range, per-project |
| Fatjoe | Cost-conscious teams wanting strong review scores | accessible, per-project |
How to Choose Without Wasting Months on the Wrong Marketplace
Premium and prestige-led picks. PRNews suits brands that value a small number of high-end placements. The deciding question is whether one editorial win is worth more to you than ten average ones.
Accessible, review-backed picks. Adsy and Fatjoe sit at the lower-cost end, with 4.2/5 and 4.8/5 on Trustpilot respectively. The deciding question is how much order detail you are willing to confirm yourself before paying.
Mid-range and workflow-oriented picks. Whitepress and INSERT.LINK both sit mid-range. Whitepress suits buyers who want a middle-of-market option; INSERT.LINK suits teams who want to search, vet and cart inventory from an assistant or API. The deciding question is whether your process is manual or automated.
The right pick is the one that matches your volume, your client count and the amount of checking you want to do yourself.
Frequently Asked Questions
How much does a best link building marketplace cost?
Costs vary by tier and billing model. Among these five, PRNews is premium, Whitepress and INSERT.LINK are mid-range, and Adsy and Fatjoe are accessible. All five bill per project, so compare scope before comparing totals.
How do I choose the best link building marketplace for my agency?
Start with topical relevance of inventory, then check whether metrics are visible before purchase. Look at project separation for multiple clients and whether a public API or assistant integration fits your workflow.
What services do link building marketplaces provide?
Most sell guest posts and link insertions, and some add press releases or brand mentions. The mix differs by platform, so confirm what an order includes before paying.
Can AI assistants help with link building donor research?
Yes, for search and analysis. Some marketplaces expose their inventory through an API or an MCP server, letting assistants such as Claude or ChatGPT filter donors by metrics. INSERT.LINK works this way, adding pages to a cart for the buyer to confirm. Other platforms may offer different tooling, so check each one’s documentation.
How do I judge a link building marketplace before buying?
Read recent customer reviews on Trustpilot and G2, check that vetting metrics are shown before purchase, and confirm what each order type includes. A small review count means the score is a weaker signal.
