Marketing online courses

How to promote an online course on social media.

Teach in public. Share small, complete lessons from your course on the platforms your students use, show what students can do afterwards, and point people to the course when they want the full path. Postomate turns your course into daily posts and publishes them for you.

Works with Gumroad, Stan, Payhip, Etsy, Lemon Squeezy, Whop or your own site.

Where course buyers spend their time.

Course buyers are paying to change something about their work or life. Go where they think about that.

  1. 1

    LinkedIn

    The natural home for career and skills courses. People here are actively trying to get better at their jobs.

  2. 2

    X

    Short lessons and threads build a following of people who learn from you, which is who buys courses.

  3. 3

    TikTok

    Bite-size lessons reach people early, before they know they need a course. Slideshows work without filming.

  4. 4

    Instagram

    Step-by-step carousels feel like a free mini-lesson and get saved for later.

  5. 5

    Reddit

    Learners ask where to start. A genuinely helpful roadmap earns trust fast.

What to post when you sell a course.

Your course already has the lessons. Posting is just releasing small pieces of them in public.

  1. 1

    A complete mini-lesson

    One technique, start to finish, in a single post. If people can use it today, they'll trust the course.

  2. 2

    The roadmap

    Show the path from beginner to able. People buy courses to skip figuring out the order themselves.

  3. 3

    Student results, with permission

    What a student built, landed or fixed. It's the most convincing post you'll ever share.

  4. 4

    Questions you get asked

    Answer one real student question per post. It shows you teach well, and it never runs out.

Example posts, written by Postomate's rules.

Each platform gets a post written for how it works, and each card shows the rule it follows.

Post on LinkedIn

A marketer on my team used to wait four days for a data request. The question was simple: which campaign brought in customers who stayed past month three? After two weeks of learning basic SQL, she answered it herself in 20 minutes. You don't need to become an analyst. You need about six commands and the confidence to use them. If you'd like to see the course she took, DM me and I'll send it over.

The rule: A lesson from your own work. The ask is “comment” or “DM me”, never “buy now”.

Thread on X

  1. Marketers: you need about 6 SQL commands to stop waiting on the data team.

  2. SELECT and FROM: pick the columns and the table.

  3. WHERE: filter to the campaign or date you care about.

  4. GROUP BY and COUNT: “how many signups per channel?”

  5. JOIN: connect signups to purchases. This is the one that changes everything.

  6. ORDER BY: put the best at the top. That's most of the job.

The rule: Teaches one thing. The product gets one soft line, in the last post only.

two weeks and you're pulling your own numbers. course in bio

The rule: Casual, lowercase, quick. The product is the last line: “in my bio”.

Three mistakes that slow course sales.

  1. 1

    Only posting during launch

    A loud launch and then silence teaches people to ignore you. Teach every week and launches get easier.

  2. 2

    Selling the curriculum

    “12 modules, 48 lessons” isn't why anyone buys. What they can do afterwards is.

  3. 3

    Giving away nothing

    If none of your teaching is public, people can't tell whether you teach well. Free lessons sell paid ones.

Questions.

How do I promote an online course for free?

Teach small, complete lessons from your course on social media, regularly, on the platforms your students use. Share student results with permission and mention the course in a few posts with the link in your bio.

What's the best platform to sell an online course?

To host it: Teachable, Kajabi, Thinkific, Podia, Gumroad or Stan all work. To promote it: LinkedIn for career courses, X for business and tech, TikTok and Instagram for broad everyday skills.

Should I give away course content for free?

Yes, in small pieces. People pay for the structure, the order and the support, not because the information is secret. Free lessons are how they learn you're worth paying.

How long before posting turns into course sales?

Higher-priced courses take longer, often a few months of regular posting. Each post adds a little trust; the sale comes when there's enough of it.
