If your #1 goal is organic discovery by learners who are already looking for courses, I’d strongly favor a marketplace over a standalone course platform.

My ranking

1. Udemy — my first choice

If you're starting with little/no existing audience, Udemy is probably the closest match to what you're describing.

Udemy explicitly positions its marketplace as a place where courses are discoverable by its learner base, and it currently reports 80M students, 1.1B enrollments, and 75+ languages. It also gives instructors Marketplace Insights showing demand, search volume and revenue information for potential topics. www.udemy.com

The important part is that you aren't simply uploading a course and hoping. Udemy's marketplace has its own search/discovery ecosystem, and instructor analytics show things such as students' interests and marketplace opportunities. www.udemy.comsupport.udemy.comteach.udemy.com

Best if your course is something like:

• Excel / Power BI
• AI tools
• Programming
• Marketing
• Project management
• Business skills
• Professional certifications
• Software tutorials
• Career skills

I'd especially choose Udemy if people are likely to search for your subject by keyword.

2. Skillshare — potentially better for creative subjects

Skillshare is unusually strong if the course is creative or project-oriented.

Its current discovery system uses search, browse and recommendations. Skillshare says its search algorithm considers relevance from the title, description and tags, while also incorporating student engagement and new classes. It also actively promotes selected teachers/classes through its platform. help.skillshare.com

The platform has also recently shifted toward fewer, more engaged teachers and higher-quality classes, rather than simply maximizing catalog size. help.skillshare.com

Good fits:

• Graphic design
• Illustration
• Photography
• Writing
• Animation
• Creative software
• Crafts
• Productivity
• Personal creative projects

One catch: Skillshare currently requires first-time teachers to apply and be approved before publishing their first class. help.skillshare.com

Teach on Skillshare

What I would not choose for this goal

I wouldn't start with Teachable, Kajabi, Thinkific, Podia, etc. if your primary objective is "people who don't know me discover my course organically."

Those are primarily course-business platforms: they give you a storefront, payments, email/marketing tools, etc., but you generally have to bring the audience yourself. That's fundamentally different from a marketplace. www.ruzuku.com

The bigger strategic point

I'd actually choose the marketplace based on how learners discover the subject:

"I want to learn X" → Udemy

"I want to make/create X" → Skillshare

"I want to learn from this particular expert, with a live cohort/community" → Maven

"I already have an audience and want to own the customer relationship" → Teachable/Thinkific/Kajabi

And there's a particularly useful tactic with Udemy: use its marketplace data before recording the course. Its Marketplace Insights tool is specifically designed to identify demand and competition around potential course topics. teach.udemy.com

If you tell me what the course is about, its approximate price, and whether it's video/self-paced or live, I can recommend the best 3 marketplaces for that specific course and explain where I'd expect the most organic traffic.

If your priority is “I want to upload a course and have learners discover me organically, without already having an audience,” my top choice is Udemy.

My ranking

1. udemy.com — best fit

Udemy is specifically built around a course marketplace, meaning learners search and browse courses on the platform rather than you having to bring all the traffic yourself. Udemy explicitly says courses are discoverable in its marketplace, and it provides a Marketplace Insights tool showing topic demand, search volume, and revenue data. Udemy Udemy Support

The economics are the major trade-off:

• 37% of net revenue for sales that aren't attributed to your own instructor promotion.
• 97% when the learner buys through your coupon/referral link.
• No upfront fee to create or host courses. Udemy Support
• You can also potentially earn from Udemy's subscription programs based on learner consumption. Udemy Support

So if you're starting with zero audience, I'd generally take 37% of a sale generated by Udemy over 100% of a sale that never happens.

Especially good for: programming, AI, Excel, business, marketing, project management, professional software, certifications, productivity, and other topics people actively search for.

2. skillshare.com — strong second choice

Skillshare also gives instructors access to an existing learner base, but its model is quite different. Teachers primarily earn based on qualifying minutes watched, rather than selling each course individually. Skillshare Help Center

It's particularly attractive for creative subjects—design, illustration, photography, animation, video, crafts, etc. Skillshare itself highlights those as major categories. Skillshare

One important 2026 caveat: Skillshare has tightened its teacher-earnings model. For example, teachers need at least 50 followers to qualify for royalty payouts under the rules introduced in 2026. Skillshare Help Center

That makes me less enthusiastic about it if your goal is purely “upload today and let organic marketplace discovery do the work.”

3. Coursera

I'd not choose Coursera if you're an independent instructor looking to simply upload a course.

It's much more oriented toward courses/programs created with universities, companies, and established organizations. It's excellent for credential-oriented learning, but it isn't the straightforward open marketplace that Udemy is for an individual instructor.

4. Teachable / Kajabi

These are excellent course platforms, but they're fundamentally different from what you're asking for.

They give you:

• your own storefront
• pricing control
• branding
• customer ownership
• marketing/email capabilities

But you generally have to bring the learners yourself.

So if the question is specifically:

“Where can I list a course and have strangers who are already looking to learn something discover it?”

I'd choose Udemy by a pretty wide margin.

The bigger strategic point

I'd actually evaluate this less as “which course platform is best?” and more as:

Which marketplace has existing search demand for my exact course topic?

Udemy gives you unusually useful information for this because its Marketplace Insights tool shows demand and search data for topics. Udemy Support

For example, there's a huge difference between:

“My course is about leadership”

and

“How to Manage Remote Software Engineers”

The second is much more likely to correspond to a specific learner search intent.

My recommendation: start with Udemy, validate the topic using its marketplace demand data, create a highly search-intent-specific course, and use the Udemy marketplace as your acquisition channel. Once you've established demand and reviews, you can consider adding your own site/Teachable/Kajabi to capture the higher-margin business.

If you tell me what subject your course teaches, I can also compare the best marketplaces for that specific subject and tell you where I'd list it first.

If your priority is “I upload a course and learners discover me organically through the marketplace”, rather than “I build my own audience and send them to my course,” the options are quite different.

My ranking

🥇 Udemy is probably what you're looking for

Udemy is the clearest fit if you don't already have a large audience. Its marketplace is explicitly designed for learners to search and discover courses, and Udemy says published courses are discoverable in its marketplace. It also provides its own Marketplace Insights tool for researching course topics before you create one. Udemy Udemy Support

The important distinction is that Udemy actually brings marketplace demand to you. Teachable/Kajabi are primarily infrastructure for selling to your audience.

The downside is economics: for sales generated organically through Udemy rather than your own coupon/referral, the current instructor share is 37% of the net amount. If you generate the sale yourself through an instructor coupon/referral, the share is 97%. Udemy Support

Udemy also has subscription programs where instructor compensation is based on learner engagement rather than individual course purchases. Udemy Support

udemy.com

🥈 Skillshare if your subject fits

Skillshare is particularly interesting for design, illustration, photography, video, animation, creative careers, and other creative subjects. Its classes are built around projects and its discovery model is subscription-based. Skillshare

However, there's a major 2026 consideration: Skillshare recently changed its teacher economics and eligibility requirements. Teacher earnings are primarily based on qualifying minutes watched, and the platform has shifted toward a smaller pool of engaged teachers/classes rather than simply maximizing catalog size. Skillshare Help Center Skillshare Help Center

So I'd choose Skillshare over Udemy only if your course is naturally suited to Skillshare's creative/project-oriented audience.

skillshare.com

The key distinction

If you're asking:

“Where can I list a course and have the platform itself find potential students for me?”

I'd go:

1. Udemy — best overall
2. Skillshare — excellent for creative topics
3. Coursera — potentially powerful but much more selective/credential-oriented
4. Teachable/Kajabi — not really marketplaces; use them once you have an audience

A useful rule is:

No audience → marketplace (Udemy/Skillshare)
Existing audience → owned platform (Teachable/Kajabi)

If you tell me what the course is about, I can also tell you which marketplace has the strongest organic demand for that specific subject and whether I'd choose Udemy, Skillshare, Coursera, or something more niche.

If your priority is “I upload a course, and learners discover me organically through the marketplace”, I’d rank the options:

1. Udemy — my first choice

Udemy is probably the closest match to what you're describing. Courses are publicly discoverable in its marketplace, and learners can find them through search and category browsing. Udemy also gives instructors traffic/conversion analytics showing how students are discovering their courses. www.udemy.com

The important distinction is that you're not merely getting course-hosting software—you are plugging into an existing learner marketplace.

Udemy also has a substantial distribution ecosystem: it says it has 80M students, 1.1B enrollments, and 75+ languages, and selected courses can be distributed through external resellers as well. www.udemy.comhelp.skillshare.com

Particularly good if your course is about:

• Programming / AI / data
• Business
• Marketing
• Finance
• Career skills
• Productivity
• Software
• Professional certifications

One caveat: the revenue economics aren't as attractive as owning your own storefront, particularly when Udemy acquires the student. But if your objective is discovery rather than maximum margin, that's often a worthwhile tradeoff.

2. Skillshare — excellent if you're teaching creative skills

Skillshare is the other serious option I'd consider. Its discovery system includes search, browsing, personalized recommendations, Learning Paths, and teacher discovery. help.skillshare.comhelp.skillshare.com

Skillshare explicitly says its search algorithm considers things such as title, description, tags, and student engagement, while its recommendation system surfaces classes based on learner interests and behavior. help.skillshare.comhelp.skillshare.com

It's especially compelling for:

• Design
• Illustration
• Photography
• Video
• Animation
• Writing
• Music
• Creative entrepreneurship
• Productivity / lifestyle skills

There is an important business-model difference: Skillshare generally doesn't sell individual classes; learners subscribe to access the catalog. help.skillshare.com

And Skillshare recently said it is deliberately moving toward fewer, higher-quality classes and more engaged teachers, which makes its current marketplace strategy somewhat different from simply maximizing catalog size. help.skillshare.com

What I would not choose for this goal

Teachable, Thinkific, Kajabi, Podia, etc. are better thought of as “build your own course business” platforms.

They're excellent if you already have an audience from YouTube, LinkedIn, email, SEO, a community, etc. But they don't solve the problem you're describing:

“I have no/limited audience. Put my course somewhere where people are already searching for things to learn and potentially discover me.”

That's precisely where a marketplace like Udemy or Skillshare has an advantage.

My recommendation

If I were starting from zero:

Professional/technical course → Udemy

Creative course → Skillshare

High-ticket course + existing audience → Teachable/Thinkific/Kajabi

And there's a potentially powerful strategy: publish a marketplace version on Udemy/Skillshare to acquire learners organically, while eventually building your own audience and higher-margin product outside the marketplace.

If you tell me what the course is about, its approximate price, and whether it's video/live/cohort-based, I can tell you which marketplace is likely to give you the best organic discovery and economics.

If your priority is learners discovering you organically inside the marketplace (rather than you driving traffic), you want a course marketplace, not just a course-hosting platform. The strongest options are:

stevewootten.comwww.thinkific.com

My shortlist by scenario

1. You have no audience and want strangers to find you
→ Udemy
It is probably the closest match to an “Amazon for courses” model: learners search, compare reviews, and discover instructors through marketplace algorithms. It works best when your topic already has demand (e.g., “Python,” “Excel,” “ChatGPT,” “project management”). www.thinkific.com

2. You teach creative skills
→ Skillshare or Domestika
These platforms are built more around browsing, inspiration, and project completion rather than searching for a specific certification. stevewootten.comwww.thinkific.com

3. You are an expert with a premium offer
→ Use a marketplace for discovery + a platform you control:

• Marketplace: Udemy/Skillshare for top-of-funnel discovery
• Owned platform: Teachable, Thinkific, or Kajabi for higher-priced courses, memberships, and customer ownership

Hosted platforms generally give you more control, but they usually require you to bring the audience yourself. creatorstackclub.com

If I were choosing purely for organic learner discovery:

1. Udemy — best general-purpose marketplace
2. Skillshare — best for creative teachers
3. Domestika — best for polished creative courses
4. Maven — best if your value is live expertise/community

A key question is: what kind of course are you listing (topic, price point, and whether it is self-paced or live)? The best marketplace changes a lot depending on that.

If your #1 goal is organic learner discovery—i.e., you upload a course and want the marketplace itself to bring students to you—I’d rank the options:

1. Udemy — best fit for what you're describing

Udemy for instructors

Udemy is explicitly built around a marketplace model: learners search for topics, compare courses/instructors, and discover courses through the platform. Its Marketplace Insights tool even gives instructors data on student demand, search volume, and revenue for potential topics. support.udemy.com

That's particularly attractive if you don't already have an audience.

It also has a public, searchable instructor profile, and Udemy says its marketplace has 90K+ instructors. support.udemy.com

Best course types:

• Software / programming
• AI
• Business
• Excel / data
• Marketing
• Career skills
• Professional certifications
• Practical how-to courses

The key is that your topic should have existing learner search demand. Udemy is much more compelling for "Learn X" than for a highly personal or abstract course concept.

2. Skillshare — excellent if you're teaching creative skills

Teach on Skillshare

Skillshare is also genuinely a marketplace, but its sweet spot is more creative/project-based learning: illustration, design, photography, video, writing, freelancing, etc.

Skillshare specifically recommends using searchable keywords in class titles and descriptions and says new classes create additional opportunities to surface in search. help.skillshare.com

One catch: you have to apply and be approved before publishing your first class, and Skillshare currently restricts what topics new teachers can publish. help.skillshare.com

Its economics are also different from Udemy: teachers earn through royalties/engagement and related programs rather than simply selling each course individually. help.skillshare.com

3. Teachable / Thinkific / Kajabi — wrong choice if discovery is the priority

These are excellent if you want to build your own education business, but they're fundamentally different from Udemy.

You create the storefront, drive traffic, build the audience, and generally have much more control. That's great once you have distribution—but it doesn't solve the problem of "How do strangers discover my course?"

My recommendation

If you mean:

"I have expertise but little/no audience. I want to upload a course and have people searching the marketplace discover and buy it."

I'd start with Udemy.

If the course is predominantly creative, I'd seriously consider Skillshare instead.

And I'd avoid paying for an all-in-one platform initially. Validate whether strangers will actually buy the course through a marketplace first.

One particularly useful Udemy feature: before producing the course, use Marketplace Insights to identify a topic with a favorable combination of search demand and competition. That's probably the single biggest advantage Udemy has for this particular strategy. support.udemy.com

If you tell me what the course is about, I can also compare the best 5–10 marketplaces specifically for that subject and tell you where I'd list it first.

If your priority is “I want to upload a course and have learners discover me organically through the marketplace”, I’d narrow it to Udemy and Skillshare, with Udemy as the strongest general-purpose choice.

1. Udemy — probably your best fit

Udemy is explicitly built around a marketplace where learners browse and search for courses from many instructors. You don't need to bring your own audience to publish; Udemy says there's no fee to become an instructor, and it provides tools such as Marketplace Insights for evaluating topics. support.udemy.com

The important distinction is that Udemy rewards you differently depending on where the learner came from:

• If a learner buys through your own coupon/referral link, you receive 97% of net revenue.
• If Udemy generates the sale through its marketplace—e.g. the learner discovers you while browsing—you receive 37% of net revenue. support.udemy.com
• There are also subscription programs where instructor compensation is based on learner engagement/consumption. support.udemy.com

So if your strategy is “make a great course around something people are already searching for and let Udemy bring the learners,” this is unusually well aligned.

The downside: Udemy's marketplace is extremely competitive, and its pricing/promotion system means you don't have the same pricing control you'd have selling independently.

2. Skillshare — excellent if your subject is creative

Skillshare is particularly attractive for design, illustration, photography, animation, video, creative careers, and similar subjects. Its classes are designed around projects and community participation. www.skillshare.com

The economics are quite different from Udemy: teachers primarily earn from a royalty pool based on qualifying minutes watched, plus certain engagement, referral, and partnership earnings. www.skillshare.comhelp.skillshare.com

One major 2026 consideration: Skillshare has been deliberately moving toward fewer, more engaged teachers and higher-quality content, rather than simply maximizing catalog size. help.skillshare.com It also now has eligibility requirements for royalty payments, including follower/watch-time requirements. help.skillshare.com

So I'd choose Skillshare over Udemy if you're teaching something like:

“Procreate illustration for beginners”

rather than:

“AWS Solutions Architect certification prep”

3. What I would not choose

Teachable, Thinkific, Kajabi, Podia, etc. are excellent if you already have an audience, but they're fundamentally course-business infrastructure, not learner marketplaces. You're largely responsible for bringing the students yourself.

That's a critical distinction:

Marketplace:
Learner → searches marketplace → discovers your course → buys

Course platform:
You → acquire audience → send audience to your site → learner buys

For your stated objective, you want the first model.

My ranking for your specific goal

If you have zero audience and want organic discovery:

1. 🥇 Udemy — best overall
2. 🥈 Skillshare — especially creative subjects
3. 🥉 Coursera — potentially huge discovery, but much less accessible to an independent instructor
4. Teachable/Thinkific/Kajabi — only once you have your own audience

One strategy I'd seriously consider is Udemy as the acquisition/discovery channel and your own platform as the long-term business. You can use marketplace demand to discover which topics actually sell, then build a higher-priced, more comprehensive offering around the winners.

If you tell me what subject the course is about + whether it's video/self-paced or live, I can give you a much more specific recommendation—including which marketplace is most likely to generate organic learners for that particular topic.

If your #1 goal is organic discovery by learners who are already searching for courses, I’d prioritize marketplaces over course-hosting software.

My ranking

🥇 I'd start with Udemy

Udemy is specifically designed around the marketplace model: learners search and browse a huge catalog of courses, while instructors compete for visibility through course topic, title, ratings, reviews, engagement, etc. Current comparisons continue to identify it as one of the strongest options for creators who don't already have an audience and want marketplace exposure. www.ruzuku.com

That makes it particularly attractive if your course is something like:

• "Python for Financial Analysis"
• "Excel for Construction Managers"
• "Learn Blender for Product Design"
• "AWS Certification Preparation"
• "How to Use AI for Real Estate"
• "French for Travelers"

In other words, a learner has a problem → searches for it → discovers your course.

Udemy also gives instructors student/market data that can help identify interests and improve or expand courses. support.udemy.com

Udemy for Instructors

🥈 Skillshare if you're in the right category

Skillshare has genuine internal discovery and a follower ecosystem: students can follow teachers and are notified when those teachers publish new classes. Skillshare also explicitly recommends building a catalog and optimizing your teacher profile for discovery. help.skillshare.com

However, it's much more category-dependent in 2026. Skillshare is currently accepting new teachers primarily in creative areas such as AI & Innovation, animation/3D, art, crafts, creative careers, design, film/video, and photography. help.skillshare.com

So I'd choose Skillshare over Udemy if you're teaching something like illustration, photography, video, design, animation, or creative AI.

Skillshare — Teach

An interesting third piece: Class Central

Class Central isn't really a course-hosting marketplace like Udemy. It aggregates courses from numerous providers and helps learners discover them. It says it has helped 80+ million people find online courses and has 200,000+ learner reviews. www.classcentral.com

So there's an interesting strategy:

Host on Udemy → get marketplace discovery → potentially get additional discovery through course aggregators such as Class Central.

What I would not choose for your stated goal

I'd avoid starting with Teachable, Kajabi, Thinkific, Podia, etc. if you don't already have an audience.

They're excellent course businesses, but fundamentally they're tools for building your own storefront. They don't solve the "learner searches for a topic and discovers an instructor they've never heard of" problem nearly as well. www.ruzuku.com

Bottom line:

If you want "I have expertise, but I don't have an audience; put my course somewhere learners already go and let them discover me" → start with Udemy.

If you tell me what subject your course teaches, its approximate price, and whether it's video/self-paced or live, I can narrow this down considerably—I can also compare Udemy vs Skillshare vs Coursera vs Maven vs Outschool vs other niche marketplaces specifically for that course.

If your priority is “list my course and let the marketplace bring me learners organically”, I’d rank the options:

🥇 My recommendation: Udemy

For your specific requirement, Udemy is the clearest fit. It has an actual course marketplace where learners search by topic, browse categories, and discover courses through the platform. Udemy explicitly provides instructors with traffic/conversion analytics showing how students are discovering their courses. support.udemy.com

The important distinction is that you're not merely getting course-hosting software. You're getting access to an existing marketplace with learner demand.

Udemy also makes instructor profiles publicly searchable, and its marketplace has mechanisms intended to improve the discoverability of quality courses. support.udemy.com

Best fit if your course is something like:

• Excel / Power BI
• Python / programming
• AI tools
• digital marketing
• project management
• business skills
• accounting/finance
• photography
• productivity
• professional certifications

The more your course corresponds to something learners already type into a search box, the better this model works.

🥈 Skillshare

Skillshare is particularly interesting if you're teaching creative or project-based subjects—design, illustration, photography, writing, animation, freelancing, etc.

Skillshare says its recommendation and search systems use factors including relevance, student engagement, and whether a class is new; it also surfaces new and trending classes through personalized recommendations. help.skillshare.com

There's an important 2026 wrinkle, though: Skillshare recently changed its teacher strategy to emphasize high-quality, engaged teachers and classes rather than simply having a huge catalog. help.skillshare.com

So I'd consider Skillshare very seriously for creative education, but Udemy is still my first choice for broad skill-based courses.

🥉 Class Central — underrated for discovery

Class Central is different.

It's essentially a search engine/aggregator for online courses, rather than a Udemy-style place where you host the course yourself. It aggregates courses from many providers and currently has a catalog of hundreds of thousands of courses. www.classcentral.com

That's potentially powerful because you're getting discovery outside the individual course platform. Class Central says more than 15 million users accessed it in 2024, and it has hundreds of thousands of learner reviews. www.classcentral.comwww.classcentral.com

So a potentially strong strategy is:

Host/sell on Udemy → get marketplace discovery → also get listed/indexed on Class Central where applicable.

What I would not choose for your goal

I wouldn't start with Teachable, Thinkific, Kajabi, Podia, etc. if your main objective is organic discovery.

They're excellent course-business platforms, but they're primarily giving you infrastructure to sell to your audience. They aren't equivalent to putting your course on a marketplace where thousands/millions of learners are already searching.

That's the fundamental distinction:

Marketplace:

“Put my course in front of people who are already looking to learn.”

Course platform:

“Give me the tools to sell a course to people I can bring.”

For your stated objective, you want the first category.

My ranking for you

If I had one course and zero audience today:

1. 🥇 Udemy — best overall organic marketplace discovery
2. 🥈 Skillshare — particularly strong for creative subjects
3. 🥉 Class Central + an underlying course platform — excellent additional discovery channel
4. Teachable/Thinkific — once you have your own audience
5. Kajabi — once you're building a larger education/creator business

If you tell me what the course is about, its approximate price, and whether it's video/self-paced or live, I can narrow this down to the 2–3 marketplaces most likely to generate organic learners for that particular course.

If your priority is “I upload a course and learners discover me organically through the marketplace”, I’d focus on true course marketplaces rather than platforms like Teachable/Kajabi that mainly give you your own storefront.

My ranking

🥇 I'd pick Udemy

For your specific requirement, Udemy is probably the closest match.

It has an actual marketplace where students search for topics and courses, rather than simply giving you software to sell to an audience you've already acquired. Published instructors have publicly searchable profiles, and Udemy provides marketplace/learner insights to help instructors identify topics and opportunities. support.udemy.com

Udemy Instructor marketplace

The important distinction is:

Udemy:

“Here is my course → Udemy has learners → Udemy's search/recommendation system can surface it.”

Teachable/Kajabi/etc.:

“Here is my course → now I need to bring the learners.”

For someone starting without a large existing audience, that's a huge difference.

🥈 Skillshare is potentially better for certain subjects

Skillshare has unusually strong built-in discovery. Its search/recommendation system considers relevance, student engagement, and newer classes, and Skillshare explicitly promotes classes through recommendations, curated features, and its homepage. help.skillshare.com

Skillshare — Teach

The catch is subject matter. Skillshare is particularly oriented toward creative skills—art, design, photography, video, animation, etc.—and uses a subscription/royalty model rather than the traditional “sell my $X course” marketplace model. www.skillshare.com

So if your course is something like:

• Photoshop
• photography
• illustration
• graphic design
• video editing
• creative entrepreneurship

I'd seriously consider Skillshare.

If it's:

• Python
• Excel
• AI
• project management
• accounting
• cybersecurity
• business skills

I'd lean Udemy.

One interesting alternative: Class Central

If by “marketplace” you mean “I want people searching Google for courses to discover mine”, rather than necessarily having the marketplace process the transaction, Class Central is worth understanding.

It aggregates courses from many providers and currently catalogs 250,000+ courses, with millions of learners using the site. Courses from major providers are automatically added, while smaller/independent providers can also be listed. www.classcentral.com

Class Central

That's more of a course discovery/search engine than a Udemy-style marketplace, but it can be valuable as another organic-discovery layer.

What I'd do

If you're starting from zero and want organic discovery rather than having to build an audience first:

1. Udemy → primary marketplace
2. Skillshare → add if your subject fits
3. Class Central → additional discovery/SEO channel
4. Teachable/Kajabi/etc. → only once you have your own audience

One caveat: organic discovery isn't passive. On Skillshare, for example, the platform explicitly says early student engagement can help a class rise in search results. help.skillshare.com So course title, thumbnail, reviews, engagement, completion, and initial traction matter enormously.

If you tell me what the course is about, its approximate price, and whether it's video/self-paced or cohort/live, I can narrow this down to the best 2–3 marketplaces specifically for that course.

If your main goal is to list a course and have learners discover you organically—without bringing your own audience—the best option is Udemy.

My ranking for organic learner discovery

Why Udemy stands out: it is explicitly a marketplace where learners browse/search for courses, and Udemy gives instructors tools such as Marketplace Insights showing student demand, search volume, and revenue for topics. It also provides traffic/conversion analytics showing how students discover courses. support.udemy.com

The economics are particularly interesting for your use case: when a learner finds your course through Udemy's marketplace without your coupon/referral, the current instructor share is 37% of net revenue. If you drive the sale with your own coupon/referral, it's 97%. support.udemy.com

Skillshare is the main alternative

Skillshare can work well if your course is in design, illustration, photography, animation, writing, creative software, or other creative fields. It has search/discovery mechanisms and even publishes data on in-demand topics to help teachers optimize for discovery. help.skillshare.com

However, its economics changed substantially in 2026: teacher earnings are primarily tied to qualifying minutes watched and other engagement/revenue mechanisms, and new eligibility requirements apply to monthly royalties. help.skillshare.comhelp.skillshare.com

What I'd choose

If you're thinking:

"I have a course, but I don't have a big audience. I want to upload it somewhere where people are already searching for what I teach."

I'd start with Udemy.

If you're thinking:

"My course is highly creative/visual and I want learners browsing for creative inspiration and skills."

I'd consider Skillshare.

And I would not start with Teachable/Kajabi if organic discovery is the priority. Those are much more useful once you have your own audience; they give you control over your storefront and customer relationship, but aren't comparable to a large learner marketplace. www.ruzuku.com

One particularly useful Udemy feature: before producing a course, you can use Marketplace Insights to see whether people are actually searching for the topic. That makes it possible to choose a niche based on demonstrated demand rather than guessing. support.udemy.com

If you tell me what the course is about, I can rank the best 3–5 marketplaces specifically for that subject and tell you where I'd publish it first.

If your priority is learners discovering instructors organically inside a marketplace (rather than you driving traffic), you want a true course marketplace, not just a course-hosting platform. The best options are:

stevewootten.comwww.mightynetworks.com

My shortlist

1. Udemy — best overall for organic instructor discovery

• Students actively search for courses.
• Works well for topics with clear search intent:
  • Python
  • Excel
  • AI tools
  • marketing
  • project management
  • design software
  • certifications
• Your ranking depends heavily on:
  • course title/keywords
  • reviews
  • completion rates
  • engagement
  • conversion rate

Best if you are an unknown instructor trying to get your first students. stevewootten.comwww.mightynetworks.com

2. Skillshare — best for creative instructors

• Strong fit for:
  • illustration
  • photography
  • writing
  • crafts
  • design
  • creative workflows
• Discovery is more browse/community driven than “search for a certification.” zapier.com

3. Hybrid approach — often the strongest long-term play
A common strategy:

1. Publish a discovery-focused course on Udemy/Skillshare.
2. Build reputation and reviews.
3. Create a premium course, community, or coaching offer on your own platform.

Marketplaces give you distribution; owned platforms give you control. creatorstackclub.com

Platforms I would not pick if organic discovery is your main goal

• Kajabi — excellent marketing/business platform, but you bring the audience.
• Teachable — excellent course storefront, but not a learner marketplace.
• Thinkific — strong LMS/course builder, weaker for marketplace discovery.

Bottom line:

• No audience + want strangers to find you: Udemy
• Creative teaching: Skillshare
• Already have followers/email list: Teachable, Thinkific, or Kajabi
• Want to build a durable instructor brand: marketplace + your own platform combination

If you tell me the type of course (e.g., AI, fitness, language, music, business, academic, hobby) and whether you’re a new instructor or already have an audience, I can narrow this down.

If your priority is “list my course and let the marketplace itself bring me learners through search, recommendations, and browsing”, I’d rank the options:

🥇 My first choice: Udemy

Udemy is probably the closest match to what you're describing.

The key distinction is that Udemy actually operates a consumer course marketplace: learners browse/search for courses, and instructors can get sales without personally referring the student. Udemy explicitly reports a 37% instructor share for sales that aren't driven by an instructor's promotion, including sales resulting from browsing the Udemy marketplace. support.udemy.com

That makes it substantially different from something like Teachable, where you're essentially building your own storefront and have to generate the traffic.

There are also subscription channels: Udemy allocates a portion of subscription revenue to instructors based on learner consumption, so discovery can potentially turn into recurring engagement rather than only individual purchases. support.udemy.comhelp.skillshare.comwww.classcentral.com

Udemy for Instructors

🥈 Skillshare — particularly good for creative subjects

Skillshare is worth considering if your course is about design, illustration, photography, video, writing, creativity, freelancing, or similar topics.

However, there's an important 2026 wrinkle: Skillshare recently changed its strategy from maximizing catalog size toward fewer, more engaged teachers and higher-quality classes. It now requires first-time teachers to be approved before publishing. help.skillshare.com

Its economics are also different from Udemy: teacher earnings are primarily tied to member engagement/watch activity rather than a conventional one-course-one-purchase marketplace. help.skillshare.com

🥉 Don't overlook Class Central

Class Central is interesting if by "marketplace" you really mean “I want people searching for courses to discover mine.”

Class Central aggregates courses from multiple providers and says it has helped 80+ million people find online courses. It can list courses from smaller platforms and independent providers as well as major platforms. www.classcentral.com

But it isn't equivalent to Udemy: generally, the learner discovers the course on Class Central and then goes to the underlying provider to enroll.

What I would do

If you're starting with zero audience, I'd use:

Udemy → primary marketplace
Class Central → additional discovery
Your own site/email list → long-term ownership

And I'd not start with Teachable/Kajabi unless you already have an audience.

The biggest caveat is that the subject of your course matters enormously. Udemy is much more attractive for something like Python, Excel, AI, project management, accounting, cybersecurity, or business than for a highly visual creative class, where Skillshare may be a better fit.

If you tell me what the course is about + approximate price + whether you already have an audience, I can give you a much more specific recommendation, including which marketplace has the best organic-discovery potential for that particular course.

If your #1 requirement is organic learner discovery—i.e., you upload a course, and learners who don't know you can find it through marketplace search/recommendations—I’d rank the options:

🥇 I'd start with Udemy

Udemy is the closest match to your description. It is explicitly a marketplace, rather than merely course-hosting software: learners search for topics, browse categories, and receive recommendations. Udemy also provides instructors with Marketplace Insights, showing search volume, learner demand, and revenue data for potential course topics. support.udemy.com

That's particularly valuable if you don't already have an audience. You can choose a topic based on existing learner demand rather than having to generate all your own traffic.

The downside is the economics: you trade some pricing/revenue control for access to Udemy's marketplace audience. www.ruzuku.com

🥈 Skillshare

I'd choose Skillshare over Udemy if your course is primarily creative—design, illustration, photography, animation, video, etc. Skillshare explicitly uses search, browse, personalized recommendations, and curated features to surface classes. Its search algorithm considers relevance plus student engagement and new-class activity. help.skillshare.com

The important distinction is that Skillshare generally pays teachers through watch-time-based royalties, rather than selling your course for a price you control. www.skillshare.com

🥉 Maven

Maven is interesting if you're selling a higher-priced cohort course around professional skills, AI, business, marketing, engineering, leadership, etc.

Its marketplace has actual organic discovery: students browse/search Maven, receive personalized recommendations, and courses can appear in algorithmic trending placements. But there's an important catch: you currently need 100 waitlist leads or 2 paid enrollments before becoming eligible for marketplace listing. So it's not as close to "upload course → marketplace finds students" as Udemy. support.udemy.comwww.skillshare.comhelp.maven.com

Maven

What I would not choose

Teachable, Kajabi, Thinkific, Podia, etc. are excellent course-business platforms, but they're fundamentally different. They give you your own storefront and tools to sell to an audience you acquire. They aren't primarily learner marketplaces supplying organic demand. www.ruzuku.com

My recommendation

If you tell me what kind of course you're planning to teach (e.g. Excel, AI, coding, fitness, photography, marketing, finance, language, etc.) and roughly how much you'd charge ($20, $100, $500+), I can tell you which marketplace has the best organic-discovery potential and economics for that specific course.
