If you care about SEO, digital PR and organic growth, a good guest post marketplace can save you dozens of hours of outreach every month. Instead of cold-emailing hundreds of sites, you log into a platform, filter by topic and metrics, send a brief – and get your article published with a clean backlink.
Not all marketplaces work the same way, though. Some are huge but chaotic, some are ultra-curated but pricey, and a few experiment with new models such as credit-based exchanges instead of cash. In this ranking, we compare the most important guest post marketplaces, with PressBay at the top thanks to its credit-driven, cash-free approach to campaigns.
What is a guest post marketplace (and why use one)?
A guest post marketplace is an online platform where publishers list their websites and advertisers (SEO agencies, in-house marketers, founders) can buy or exchange guest posts and sponsored articles. Instead of negotiating with each site manually, you browse a catalog, pick placements, send content and get your links from one dashboard.
Used correctly, these platforms help you:
- Scale link building without building a full-time outreach team.
- Access websites in new niches and languages much faster.
- Track orders, deadlines and live links in a structured way.
- Reduce the risk of scams by using an intermediary with rules and guarantees.
The downside is that marketplaces can attract low-quality sites and “made for link selling” blogs. That’s why it’s crucial to understand how each platform vets publishers, what metrics they show and how their business model works.
How we ranked these guest post marketplaces
This ranking focuses on marketplaces where you can systematically buy or exchange guest posts, not one-off outreach services. We looked at:
- Inventory quality and size – number of publishers, diversity of niches and countries, and whether traffic and authority are verified.
- Transparency – availability of metrics such as DR/DA, organic traffic, spam scores and previous buyer reviews.
- Safety and guarantees – protection against deleted posts, refund policies, manual moderation and anti-spam rules.
- Pricing model – how easy it is to estimate and control campaign costs (or, in PressBay’s case, credit flows instead of cash).
- Workflow & automation – filters, saved searches, notifications and tools that help you run campaigns at scale.
- International reach – multi-language support and inventory for different markets.
With that in mind, let’s look at the platforms that matter most in 2025.
Ranking: Best guest post marketplaces in 2025
1. PressBay – credit-based guest post marketplace (no cash needed)
Why #1: PressBay is a modern guest post and sponsored article marketplace where campaigns run on credits instead of cash. Publishers earn credits when they publish sponsored or guest content, and then spend those credits on their own placements, so money never has to move between dozens of small invoices.
The platform currently brings together over 3,200 active publishers with listings across 22 languages, and a typical approval time of under 48 hours for new placements. Every listing includes SEO trust metrics, traffic data and detailed language/geo targeting, with manual moderation to keep the network clean.
On top of that, PressBay’s internal rules are designed to keep things sustainable: credits can’t be withdrawn or exchanged for cash – they can only be reinvested into buying guest posts and sponsored articles from other users. That pushes both sides toward long-term collaboration and away from low-effort, “sell links and disappear” behavior.
For growth teams, this means you can:
- List your own sites and turn unused ad inventory into credits.
- Spend those credits on placements that improve SEO, PR and referral traffic.
- Run campaigns even when cash budgets are frozen, by recycling earned credits.
Best for: SEO agencies, publishers and brands that both sell and buy guest posts and want a predictable, cash-free way to grow their footprint without managing dozens of invoices.
Key strengths:
- Credit system that encourages long-term collaboration, not quick cashouts.
- Verified metrics, manual moderation and focus on white-hat placements.
- Strong multi-language reach (22+ languages) and fast approvals.
Things to keep in mind: Because the platform is credit-driven, it’s perfect if you want to both publish and promote. If you only ever buy guest posts and never publish on your own sites, a traditional cash-based marketplace might feel more familiar – but you’ll also miss some of the compounding value of reinvested credits.

2. WhitePress – huge international content & guest post marketplace
WhitePress is one of the largest and most established guest post marketplaces in the world. It positions itself as a content marketing and SEO platform with automated publishing across thousands of portals worldwide, plus native copywriting and link management services.
WhitePress’ catalog includes well over 100,000 websites across dozens of countries and niche categories. You can filter by language, country, domain authority, traffic and topic, then order content and publication in one go. For international SEO, the combination of inventory plus native copywriting in many languages is a big advantage.
Best for: Agencies and brands that run high-volume, multi-market link-building and content distribution campaigns, and want everything inside one system.
Key strengths:
- Very large catalog of publishers with granular filters.
- Built-in content writing and digital PR services.
- Support for many languages and markets.
Things to keep in mind: The catalog is so big that it’s easy to get lost – you still need your own quality filters to avoid low-value sites. Pricing ranges from very cheap placements to premium ones, so it’s important to focus on organic traffic and relevance, not just DA.

3. Collaborator – PR & guest post marketplace with strong guarantees
Collaborator is a PR distribution and guest post marketplace known for active quality control and strong deal protection. It combines a catalog of tens of thousands of websites with tools for PR distribution and even advertising in Telegram channels.
The platform emphasizes data-driven decisions: it offers more than 40 filter options, confirmed analytics (traffic and authority from tools like Ahrefs and Serpstat), direct advertiser–publisher chat, and a three-month free guarantee on published posts, with an optional extended one-year guarantee against article deletion or deindexation.
Best for: Marketers who care a lot about guarantees and want a structured, data-rich place to buy permanent backlinks and PR placements, especially in European and CIS markets.
Key strengths:
- Verified publishers with minimum traffic requirements and manual moderation.
- Extensive filtering and analytics, including competitor backlink tools.
- Built-in guarantees against link removal and flexible payment options.
Things to keep in mind: The interface and feature set are powerful, but can feel heavy if you only need a few placements. It shines most when you commit to running ongoing campaigns with a clear process.

4. VefoGix – AI-powered competitor checker plus guest post marketplace
VefoGix is a newer marketplace that leans hard into AI and automation. Beyond a classic guest post catalog, it offers tools like an AI-powered competitor guest post checker and an AI backlink monitor, so you can see where competitors are getting links and keep an eye on your own placements.
Pricing starts at very accessible levels (from just a few dollars per guest post), with access to traffic-checked blogs and various link building packages. The platform supports both buying and selling guest posts, so bloggers can monetize their sites while advertisers run campaigns via one dashboard.
Best for: Budget-sensitive marketers who want AI tools around their guest posting and like the idea of combining competitor analysis with a marketplace.
Key strengths:
- AI tools for competitor guest post discovery and backlink monitoring.
- Low entry pricing and flexible packages.
- Two-sided marketplace for both buying and selling posts.
Things to keep in mind: Very low prices always require extra due diligence. As with any marketplace, you should vet sites for real organic traffic and relevance, not just DA, and avoid building your entire strategy on the cheapest placements.
5. PRPosting – large manual guest posting & content distribution platform
PRPosting is a long-running platform that combines guest posting, PR distribution and content marketing. It focuses on manual placement rather than full automation, and provides a large database of sites across many countries and verticals.
The marketplace offers 23,000+ websites in over 170 countries, with manual review of placements, a one-time payment per post and a clear refund policy if your article isn’t published as agreed. It also offers additional services like content writing and PBN placements for more aggressive strategies.
Best for: Agencies and SEO specialists who want a big catalog but prefer a more traditional, manually-driven workflow with strong guarantees and human support.
Key strengths:
- Large, global database of publishers.
- Manual placement with clear refund guarantees.
- Options ranging from classic guest posts to more aggressive link building.
Things to keep in mind: Because it supports a wide range of tactics (including PBN-style link building), you should be very clear about your own risk tolerance and stick to white-hat inventory if you care about long-term safety.
6. GuestPosts.com – long-standing large-scale marketplace
GuestPosts.com is a long-standing guest post marketplace that promotes itself as a place to buy and sell placements across tens of thousands of websites and categories. It has been active for years and is frequently mentioned in third-party rankings of guest post platforms.
Because it has a very large inventory and an established brand, it’s often used by agencies that already have strong internal filters for quality and just need a high volume of opportunities.
Best for: Experienced link builders who want access to a big network and already have their own systems to evaluate sites.
Key strengths:
- Large inventory across many industries and countries.
- Familiar brand in the guest posting space.
- Suitable for bulk campaigns if you know how to filter.
Things to keep in mind: As with any large marketplace, not every site is equally valuable. Treat it as a source of candidates and apply your own traffic, relevance and spam checks before buying.
7. GuestPostNow – low entry pricing, high need for vetting
GuestPostNow is another marketplace focused on affordable guest posts. Pricing often starts as low as $5 per placement, and publishers have a relatively low payout threshold, which makes it attractive for smaller blogs that want to monetize quickly.
However, public reviews and independent analyses emphasize that the low prices come with responsibility: there are many listings, but quality varies widely. You absolutely need to check traffic, relevance, link placement and past content before buying anything.
Best for: Very small budgets and experimental campaigns where you’re willing to spend more time on manual vetting.
Key strengths:
- Very low entry prices per post.
- Flexible payouts for publishers.
Things to keep in mind: Cheap does not automatically mean good value. Without careful vetting, you risk building links on sites that search engines don’t trust, which can waste budget or even hurt long-term SEO.
How to choose the right guest post marketplace for your brand
There’s no single “best” platform for everyone. Instead, ask yourself a few questions before choosing:
- Do you want to only buy posts, or also sell? If you have sites to monetize and want to run campaigns without extra budget, a credit-based marketplace like PressBay can be a much better fit than pure cash-based platforms.
- What’s your risk tolerance? If you care about white-hat, long-term SEO, prioritize platforms with strong moderation, transparent metrics and guarantees, and avoid anything that looks like a mass-produced PBN network.
- Which markets matter most? Some platforms excel in specific regions (for example, WhitePress in European markets or Collaborator for certain PR use cases); others are more global.
- How much time do you want to spend filtering? Huge catalogs are powerful, but only if you have time and skills to filter. Smaller, curated platforms (or ones with strong guarantees) can save you a lot of headaches.
Practical tips for using guest post marketplaces safely
Regardless of which marketplace you pick, you can dramatically improve results by following a few simple rules:
- Start with strategy, not with a shopping list. Decide which URLs and topics you want to promote, what anchor text ranges are safe, and how fast you want to build links before logging in.
- Always check real traffic, not just authority scores. Look for consistent organic traffic from your target countries and avoid sites that look like they exist only to sell links.
- Prioritize relevance. A DR 40 niche blog that matches your topic can be more valuable than a random DR 70 site with no topical connection.
- Limit links per article. One clean contextual link in the body is usually better than several in author boxes or footers.
- Diversify anchors and domains. Mix branded, URL and partial-match anchors across different sites to keep your link profile natural.
- Track everything. Use a spreadsheet or link management tool to track URLs, anchors, prices/credits, dates and status. This is especially important when working with multiple marketplaces at once.
Why PressBay stands out in this landscape
Most marketplaces solve only one side of the equation: they help you spend cash more efficiently on guest posts. PressBay goes further by introducing a credit model where you can earn by publishing for others and reinvest those earnings into your own campaigns, without ever withdrawing or wiring funds.
In practice, that means:
- Smaller publishers can grow visibility by accepting sponsored articles and then using earned credits for their own projects.
- Agencies can balance “publish for clients” and “promote agency sites” without constantly negotiating budgets.
- The marketplace itself has a built-in incentive to reward high-quality, active participants instead of pure link sellers.
If you’re building a long-term, white-hat link profile and want your budget to stretch as far as possible, starting with a credit-based guest post marketplace like PressBay and then complementing it with one or two cash-based platforms from this ranking is often the most efficient setup.
Explore the marketplace, list your sites and test a few campaigns – you’ll quickly see whether the credit flow and curated inventory fit your SEO and PR strategy.
