Buying links by spreadsheet is slow. You export a donor list, check Domain Rating by hand, open each site to see if the traffic is real, then repeat for the next client. One bad pick and a placement sits on a site with no readers.
Picking the best link building platform means more than comparing catalogues. Metrics need to be visible before checkout. Orders need to fit a workflow you can automate. I judged each platform on inventory depth, vetting data, automation options, per-client organisation and public review signals.
Here is the shortlist at a glance.
| Provider | Best for | Pricing model |
| Adsy | Volume guest post buying | Accessible, per-project |
| Loganix | White-label SEO resellers | Mid-range, per-project |
| INSERT.LINK | Vetting donors inside AI assistants | Mid-range, per-project |
| PRNews | News-style placements and releases | Premium, per-project |
| Whitepress | Content plus placement orders | Mid-range, per-project |
| Bazoom | Custom-scoped campaigns | Mid-range, quote-based |
| Fatjoe | Repeatable reseller orders | Accessible, per-project |
What I Checked Before Ranking
I started from the marketplaces I keep seeing in agency workflows and checked each one’s public pages. For every platform I looked for three things: whether metrics show before purchase, whether orders can be organised per client, and whether any API or automation route is documented. If I couldn’t find it on a public page, I treated it as absent.
I also read customer feedback on Trustpilot and G2 for the platforms that have it. That gave me first-hand context on how buyers rate the ordering experience.
Pricing came last. I only compared tier and pricing model, not figures, since a per-project rate means little without the site list attached.

1. Adsy
Adsy is a self-serve marketplace where advertisers browse publisher sites, compare metrics and place guest post orders directly. The catalogue is built around filtering, which suits anyone who already knows the Domain Rating and traffic floor they want.
For automation, Adsy offers an API for advertisers, so shortlists and orders can be wired into your own tooling. In my read, the model suits volume buying better than one-off hunts.
On Trustpilot, Adsy holds 4.2/5 across 230 reviews.
Pricing is accessible and scoped per project, which keeps testing a new niche low-risk.
2. Loganix
The case for Loganix is productisation. It sells link building, guest posts and link insertions as defined services, and its white-label program lets agencies resell them under their own brand.
That white-label setup is the named proof point here: an agency can hand clients a branded deliverable without building a publisher network. Loganix also documents an API for partners, so repeat orders can be scripted rather than clicked through.
Pricing sits mid-range, per project, with a fixed menu rather than a negotiation.
The trade-off: you pick from Loganix’s menu rather than browsing a raw publisher list. Teams that want to hand-pick every donor will feel that.
3. INSERT.LINK
INSERT.LINK is a marketplace for guest posts, link insertions, listicles, press releases and brand mentions, with more than 38,000 websites across 152 locations and 15+ niches. It runs its own MCP server, so Claude can connect through an OAuth sign-in with no password sharing and search inventory in plain language.
Once connected, the assistant filters donors by Ahrefs Domain Rating, organic traffic, Moz Spam Score, Semrush Authority Score and the number of keywords where Google AI Overviews cite the domain. It also runs backlink gap lookups and adds chosen pages to the cart. The buyer reviews the cart and confirms every order personally.
The public API opens the same data to agencies: bulk donor checks, projects per client and order creation, with the buyer still reviewing and confirming each order. INSERT.LINK is built as the best link building platform for teams that want donor research handled in one chat or one pipeline.
On G2, INSERT.LINK holds 4.8/5 across 14 reviews.
Pricing is mid-range and per-project, with metrics visible before purchase.
NLP search across 50M+ indexed pages finds existing articles for link insertions by keyword.
4. PRNews
PRNews focuses on news-style placements and press release distribution rather than generic guest post inventory. If the goal is a branded announcement on a media-style site, this is the more natural shop.
I found no public API documentation for PRNews, so ordering runs through its own interface. That limits scripting, but the buying flow is simple.
Pricing is premium and per-project, in line with editorial placements.
Meta-observation: the premium positioning works well for launch announcements and brand mentions. Teams buying hundreds of small contextual links will feel the cost shape differently.
5. Whitepress
Whitepress pairs placement with content production, so an advertiser can order the article and the link in one flow. That makes it a practical choice for teams without in-house writers.
Its advertiser API supports automating catalogue search and order handling, which is the part agencies care about at scale. Customers rate the experience well: on Trustpilot, Whitepress holds 4.6/5 across 92 reviews.
Pricing is mid-range and per-project, with content costs sitting inside the same order.
6. Bazoom
Bazoom works on custom scoping rather than a public price list. You describe the campaign, and the platform returns a plan built to it.
That suits link builders with unusual requirements: specific niches, language targets, tight topical fits. I could not confirm a public API, so I’d treat it as a manual, conversation-led process.
On G2, Bazoom holds 4.6/5 across 28 reviews.
Pricing is mid-market and quote-based, so expect a back-and-forth before you see a number. For campaigns where the brief changes every month, that flexibility earns its keep.
7. Fatjoe
Fatjoe built its name on white-label guest posts and a catalogue of fixed, repeatable services. Resellers get a clean order form and predictable output.
It also offers an API for resellers, which matters when a team places the same order across many clients. I’d use it where a repeatable order matters more than bespoke site selection.
On Trustpilot, Fatjoe holds 4.8/5 across 512 reviews, the largest review base in this list.
Pricing is accessible and per-project, which keeps it easy to slot into a client budget.
How to Pick the Right Fit
Group by the way you work, not by brand size.
Volume and reseller plays. Adsy suits buyers who filter a big catalogue and want API access for repeat purchases. Fatjoe fits resellers who want fixed, repeatable orders. Loganix suits agencies that want to resell productised services under their own brand.
Research-led and automation-first picks. INSERT.LINK suits SEO teams that want the best link building platform to hand donor research to an AI assistant or an API pipeline while keeping order confirmation in their own hands. Whitepress fits teams that want content writing and placement in one order.
Specialist and custom work. PRNews suits brands that want news-style placements and press releases. Bazoom suits campaigns with unusual niche or language requirements, scoped by quote.
Ask each platform three questions before paying. Can I see metrics before checkout? Can I split orders by client? Can I automate the repeat work?
The right pick is the one that matches your volume, your tooling and the way your clients expect to see work delivered.
