How we compared them
Every marketplace below is evaluated against the same seven criteria. Sources are public pricing pages, publisher count claims from each vendor, and our own purchasing experience where applicable.
Disclosure. Adbassador is a guest post and ad marketplace that we operate. We are listed first in alphabetical order, not ranked first. We did not exclude direct competitors. Competitor data is sourced from their own published claims at the time of writing.
The seven criteria
- Starting price. Lowest publicly listed placement price, USD.
- Publisher count. Vendor-claimed inventory at the time of writing.
- Model. Self-serve marketplace, fully managed agency, or both.
- Vetting. How sites are reviewed before listing (manual, automated, none disclosed).
- Metrics shown. Which third-party site metrics buyers can filter or sort by.
- Link guarantee. Replacement or refund terms if the placement is removed.
- Format range. Guest posts only, link insertions, or multi-format (banners, PR).
We did not assign star ratings or “best of” tiers. Marketplaces serve different buyer profiles: a self-serve $5 placement is not directly comparable to a $200 fully managed outreach campaign. Use the comparison to filter by what matters to you.

Frequently asked questions
What is a guest post marketplace?
A guest post marketplace is a platform where advertisers can buy sponsored articles, link insertions, or other content placements on third-party websites at listed prices. Marketplaces aggregate publisher inventory so buyers can filter, compare, and purchase without manual outreach.
How do guest post marketplaces differ from managed link building agencies?
Marketplaces are self-serve: you browse listings, filter by metric, and order. Managed agencies do outreach on your behalf, charge more, and typically take 4 to 8 weeks per placement. Some platforms (FatJoe, VefoGix) offer both models. The HOTH, Loganix, and GetMeLinks are agency-only.
Are guest post marketplaces safe for SEO?
It depends on the marketplace. Manually vetted marketplaces (Adbassador, GuestPostOn) reject low-quality and PBN sites at intake. Bulk databases with minimal vetting carry more risk because you may end up linking from spam-tagged domains. Always check spam score and the publisher’s outbound link profile before placing an order.
What is the cheapest guest post marketplace?
Adbassador, GuestPostNow, and VefoGix all start at $5 per placement. Pricing scales with site DR and traffic, so a $5 entry point on any of these will be a low-DR site. Mid-DR placements in the $50 to $150 range are more comparable across marketplaces.
What does “vetting” actually mean across these platforms?
Vetting varies widely. Manual review (Adbassador, GuestPostOn) means a human checks each site for PBN signals, real traffic, and editorial quality before listing. Light or automated vetting checks DA, DR, and spam thresholds. “Not disclosed” means the platform does not publish its review process. Bulk databases (Serpzilla) skip vetting and rely on metric filters.
What is a link guarantee?
A link guarantee is the marketplace’s policy if your placed link gets removed by the publisher within a stated window. The HOTH and GetMeLinks offer 12-month replacement. Link Publishers and GuestPostNow offer 90-day or 6 to 12 month replacement. Adbassador focuses on editorial QA before publish so removals are rare; refund and replacement are handled case by case.
Should I use a self-serve marketplace or a managed agency?
Self-serve is faster and cheaper if you can evaluate publisher metrics yourself: DR, traffic, niche fit, outbound link profile. Managed agencies are worth the premium when you need outreach to sites that aren’t on any marketplace, when you have no time to filter listings, or when you need predictable monthly placement volume from a fixed budget.
How long does a guest post placement take?
Self-serve marketplaces: 2 to 14 days depending on the publisher’s editorial backlog. Adbassador reports 96% of orders live within 48 hours. Managed agencies (HOTH, Loganix) take 4 to 8 weeks because they include outreach, negotiation, and content production.
Why is Adbassador listed first in this comparison?
Alphabetical order. We did not exclude direct competitors and we did not assign rank-based scores. The methodology section above discloses that we operate Adbassador. Use the seven-criteria table to filter by what matters to your campaign.
Do these marketplaces accept all niches?
Most marketplaces restrict adult, gambling, CBD, crypto, and pharma to specific publishers who allow those niches, often at premium prices. General B2B, SaaS, ecommerce, finance, and lifestyle niches are accepted across all 15 platforms. Always check the niche filter on the platform before assuming inventory exists.
