B2B marketplaces don’t have one content problem. They have two.
A B2B marketplace has to serve two audiences with its content. One side is trying to attract buyers. The other is trying to attract suppliers. Each group has different questions, search behavior, and reasons to convert. Content that works for one side often does little for the other.
Hiring a content agency for a B2B marketplace requires a different evaluation process. Beyond content quality, you need an agency that understands two-sided growth, can build authority in competitive categories, and knows how to create content that drives marketplace activity, not just traffic.
The six agencies on this list were selected because they have either worked with marketplace-type businesses or bring a methodology that maps to how marketplace content actually needs to work. Each one is evaluated on what they do, who they work with, how they price, and how they approach content strategy differently.
What B2B Marketplace Content Actually Requires
Understanding what marketplace content actually demands will help you ask better questions during any agency evaluation and filter out agencies that don’t understand the problem you’re trying to solve.
Buyer Content and Supplier Content Need Equal Attention
Standard SaaS content is written for one buyer. Marketplace content has to work for at least two. On the buyer side, that means comparison guides, category pages, trust-building case studies, and use-case content that answers “why should I source from this platform instead of a direct relationship?” On the supplier side, it means acquisition content, onboarding resources, and practical guides on how to win business through the platform. Vendors need content that explains why listing on your platform is worth their time, who the buyers are, and what winning looks like after they’re on board.
These two audiences search differently, distrust for different reasons, and need different things before they take action. Running one content strategy and hoping it serves both rarely produces results for either side. An agency that understands this will build separate keyword maps and intent frameworks for each audience from day one.
A Blog Alone Won’t Scale a Marketplace Programmatic SEO is part of the job
Marketplaces with multiple product categories, supplier types, or geographic coverage quickly outgrow what a standard editorial calendar can produce. That’s where programmatic SEO comes in, building templated, search-optimized pages systematically across every meaningful combination of category, location, and buyer intent. Searches like “B2B wholesale office supplies for small businesses” or “procurement software for manufacturing teams” exist at volume, and they convert. Most content agencies aren’t equipped to execute this. The ones on this list that can are noted in their profiles.
Domain Authority Is Usually the First Obstacle
Newer and mid-stage B2B marketplaces are almost always competing for category keywords against incumbents that have years of domain authority built up. Publishing more blog posts won’t close that gap quickly enough. What actually moves domain authority is content that earns links: original research, data-backed industry reports, and assets that publishers and industry sites want to reference. Agencies that pair strong content production with a genuine link-earning capability are significantly more useful at this stage than those focused purely on content volume.
Awareness Content and Conversion Content Both Have a Role
A post ranking for “what is B2B procurement” builds visibility over time and can be valuable, but it will not grow a marketplace on its own. The content that drives platform metrics like supplier sign-ups, buyer transactions, and demo requests targets people further along in the decision process. These are buyers comparing platforms, suppliers weighing distribution options, and decision-makers with a clear problem and a willingness to act.
A strong marketplace content strategy covers both levels of the funnel. The difference is that most agencies default to top-of-funnel content because that’s where the search volume is. Conversion-focused content should be prioritized first, and awareness content built on top of that foundation.
AI Search Has Changed How B2B Buyers Find Platforms
B2B buyers don’t start their research exclusively on Google anymore. A growing share of purchase decisions now begins with a query in ChatGPT, Perplexity, or Google AI Overviews. According to Adobe Analytics data, generative AI referral traffic to U.S. websites grew 1,200% between July 2024 and February 2025. If your platform isn’t appearing in those AI-generated answers, you’re invisible to a meaningful and growing segment of buyers before they ever reach your organic rankings. Any agency worth hiring in 2025 should have a specific answer for how they build AI search visibility — not just a line item that says “GEO available.”
How We Selected These Agencies
Four things guided this list. First, documented experience with B2B marketplace clients or two-sided platform businesses. Second, a methodology that directly addresses the real content challenges marketplaces face. Third, transparent or independently verifiable pricing. Fourth, published case studies or independent third-party reviews confirming real client work.

Here are 6 of the best SEO agencies for B2B marketplaces:
1. Your Content Mart
Most content agencies measure success with traffic. At Your Content Mart, we measure it with signups. That one difference shapes everything about how we approach a content program: what we research at the start, what we produce, and what we report on at the end.
Every engagement starts with customer interviews and hands-on product research. We interview your recent buyers and active platform users to understand the exact language they used when searching for a solution before they found you. Alongside that, we spend time inside the product itself, working through the platform, mapping features to real use cases, and understanding how different user types would actually use it. The interviews surface what buyers search for. The product research ensures we write about it accurately, which is what separates genuinely useful content from generic SEO content.
For a B2B marketplace, those interviews reveal searches happening on both sides of the platform. Buyer-side interviews surface queries like “[current workflow] alternatives for procurement teams” or “how to manage [supplier category] across multiple locations.” Supplier-side interviews uncover searches like “how to reach enterprise buyers in [industry]” or “best platforms for [product category] vendors.”
From there, every piece of content we produce falls into one of these categories, each targeting a specific stage of the buyer’s evaluation:
- Alternative pages: These capture buyers in active evaluation mode. A search like “[marketplace competitor] alternatives” means someone has already considered a leading option and is now looking at what else exists. We write these to position your platform within that consideration set, with specific product context and real evidence.
- Comparison pages: “[Your platform] vs [Competitor]” pages handle the direct evaluation question before a prospect raises it in a sales call. We write these with actual product comparisons, use-case specificity, and clear positioning rather than generic feature tables.
- JTBD (Jobs-to-be-Done) content: These intercept buyers before they know your platform exists. If your marketplace connects businesses with logistics providers, a buyer searching “how to manage freight procurement for a distributed team” is a live prospect. We answer their current problem and introduce your platform naturally as the next step.
- Solution guides: Practical, product-integrated guides that demonstrate your platform’s value while solving a specific workflow problem. They walk buyers through the platform for a real task, with screenshots and actual product examples.
- Use case content: Industry and role-specific content that shows exactly how your marketplace works for a particular type of buyer or supplier. This builds trust on both sides of the platform with content that speaks directly to a reader’s situation.
We build every article as a mini sales page, in the sense that the product is woven into every section with purpose. Real product examples, actual platform screenshots, and CTAs that match where the reader is in their evaluation. We also write with AI search in mind from day one: clear structure, direct answers, and entity-rich content that language models pull from when buyers ask for platform recommendations in ChatGPT or Perplexity.
Results we’ve achieved using this process
OneCal is a bootstrapped calendar sync SaaS that came to us competing against other well-funded competitors. When we started, OneCal had 8,000 monthly clicks and sat at position nine for its core keyword.
We identified three things: thin pages that needed updating, JTBD content opportunities around searches their buyers were already making, and alternative page gaps that better-funded competitors had left open. Five months later, OneCal was at 31,300 monthly clicks; a 291% increase. They ranked #1 in Google’s AI Overview for “calendar sync software,” above Calendly and Reclaim.ai.
By September 2024, seven months after the engagement ended, traffic had grown to 40,000 monthly clicks without any additional work from either side. The content kept compounding on its own.
With Copysmith, an AI copywriting SaaS, the starting problem was different. Organic traffic existed but wasn’t converting, they had 529 monthly organic sign-ups despite a consistently published blog. Customer interviews revealed the issue: the content was targeting informational keywords while buyers were searching comparison and alternative queries. They were ready to buy, but the content wasn’t meeting them at that stage. We rebuilt the strategy around comparison and alternative pages targeting those high-intent searches.
Copysmith’s traffic and conversion rates before working with Your Content Mart
Over eight months, monthly organic sign-ups grew from 529 to 3,457, a 553% increase. Organic conversion rate improved from 13.2% to 23.7%, and organic search became their number one acquisition channel.

How Content Strategy Changes for B2B Marketplaces
Understanding the content challenges is one thing. Knowing how to sequence and structure the strategy is another. These are the practical decisions that separate a marketplace content program that compounds from one that produces traffic with no clear connection to platform growth.
Start with the searches closest to a transaction
The natural instinct is to start at the top of the funnel because that’s where the search volume is. For an early-stage marketplace, that usually means months of content that builds impressions but doesn’t drive sign-ups. Comparison pages, alternative pages, and category-specific content targeting buyers who are actively evaluating options convert faster and connect more directly to platform transactions. That doesn’t mean awareness content gets ignored permanently. It means the conversion-focused work gets built first, and awareness content follows as the program matures and the platform has the authority to rank for broader terms.
Set different success metrics for each side of the platform
Buyer-side and supplier-side content should be measured separately. Buyer content success looks like demo requests, trial sign-ups, and first transactions. Supplier content success looks like vendor registration rates, listing completions, and onboarding completion. Running both under a single traffic-based KPI makes it nearly impossible to see what’s actually working. Programs with separate measurement tracks produce more useful data and make optimization decisions significantly cleaner.
Build category by category, not all at once
Treating the entire marketplace as one content project produces a sprawling editorial calendar that’s hard to prioritize and harder to measure. A more effective approach is to sequence content by category or vertical, building complete coverage for one buyer or supplier segment before moving to the next. This creates topic clusters that rank better, builds internal link equity more efficiently, and lets you observe actual category-level conversion data before scaling the same approach across the whole platform.
Supplier spotlight content earns more trust than platform claims
Buyers on a B2B marketplace carry more risk than buyers of a SaaS tool. They’re not evaluating software; they’re trusting a platform to connect them with real vendors who will deliver real goods or services. A page that says “we have 5,000 verified vendors” is a claim. A content series that profiles actual vendors with specific examples, real client outcomes, and verifiable details is evidence. Supplier spotlight content builds buyer confidence and gives listed vendors a reason to invest in the platform. It’s one of the most underbuilt content types in marketplace programs.
Finding the Right Content Agency for Your B2B Marketplace
The best content agency for a B2B marketplace understands that growth isn’t just about attracting more traffic. It’s about bringing buyers and suppliers onto the platform and creating enough momentum for transactions to happen.
That’s why marketplace content requires a different approach from traditional SaaS content marketing. The strategy has to account for both sides of the marketplace and guide each audience toward meaningful actions.
At Your Content Mart, that’s how we approach every engagement. Using our Signup Engine Framework, we research both sides of your marketplace, identify the buyer-intent keywords that matter most, and build separate content tracks for buyers and suppliers. Every piece of content is designed with a clear conversion goal in mind, whether that’s generating supplier applications, driving quote requests, or increasing product signups.
If you’re evaluating agencies from this list, one question you should be asking is: How would you approach content for our buyers differently from content for our suppliers?
The answer will tell you a lot about whether the agency truly understands marketplace growth.
Frequently Asked Questions (FAQs) About Best Content Agencies for B2B Marketplaces
What does a B2B marketplace content agency do?
It creates content that drives buyers and suppliers to your platform and moves them toward transactions, including SEO content, buyer guides, category pages, comparison pages, and programmatic SEO at scale. Strong agencies also optimize for AI search tools like ChatGPT and Perplexity, not just Google.
How is B2B marketplace content different from SaaS content?
A SaaS company writes for one buyer. A marketplace has to serve at least two: buyers who need to trust the platform and suppliers who need a reason to list. Those audiences have different search behaviors and require separate content programs to convert.
How much does a B2B content marketing agency charge?
The agencies on this list range from $3,500 to $10,000+ per month, depending on scope and services. Your Content Mart starts at $3,500/month (Standard) and $5,500/month (Growth), while Omniscient Digital’s full-service engagements begin at $10,000/month.
Can a content agency handle content for both sides of a B2B marketplace?
Some can, but most don’t approach it that way by default. Ask any agency you’re evaluating how they’d build separate strategies for your buyers and suppliers.
