As a content creator, I've created over a dozen online courses, which have earned me over a million dollars. However, I'm not the only one earning from online courses.

In 2021, online courses brought in around $214.26 billion. The market is projected to grow to over a trillion dollars by 2030.

With the rise of YouTubers, influencers, and creators, combined with the changing consumer behavior habits and the shift to e-learning, creating online courses has become a sustainable income option.

Plus, scaling is a no-brainer since overhead costs are low, and creating a course takes less than a few days or weeks.

So, if you want to try creating your own course and gain authority while reaching a global audience, check out which is the right course idea for you.

The 20 Most Successful Online Course Ideas

You can use countless ideas to start an online course, but are there ones that can generate more income for you?

Yes, there are, but you need to know that while 80% of people enjoy video e-learning courses, there's still a market for text-based courses or courses that also include a workbook, planner, or ebook.

Knowing this information can help you decide what deliverables to create.

So, based on your niche or industry, here are the most successful online course ideas.

1. Finance Online Course

Finance has many sub-niche topics, such as personal finance, business finance, investing, taxation, insurance, wealth management, and financial technology (FinTech), that all make great course ideas.

If you're in finance as a junior accountant, in sales and trading, act as an insurance agent, are good at budgeting for your large family, or have accomplished a feat like living off of credit cards for a specified time, you can create an online finance course.

For example, The Budget Mama created her signature Building Blocks of Budging online course with video lessons and templates.

How Do I Know Which Course Idea is Best for Me?

The best course idea depends on your skillset, audience, and competitor research analysis.

Your Skillset

When deciding on your online course idea, consider your skills and what skills you're promoting online to grow your audience and business.

Consider your unique experiences, professional background, and any specialized training you have received.

There are thousands of online writing courses, but my course is different from others because of my experience, knowledge, and success with writing.

This will help you establish credibility and make it easier to create high-quality content that resonates with your target audience.

For example, if you have a background in digital marketing, you might create a course on social media strategy or search engine optimization. If you’re a seasoned graphic designer, you could develop a course on mastering design software or branding principles.

Once you’ve identified your skills and researched your market, outline your course content, break it into manageable modules, and consider the best delivery methods, such as video lectures, interactive quizzes, and downloadable resources.

If you grew your audience on TikTok, then short digestible videos for your course would be the best option since your core audience enjoys short videos.

Your Audience

I'm sorry to say that if you haven't cultivated an online audience, you'll make very few course sales. 

You don't have to grow to 10,000 or 20,000 followers to sell your course or digital products; a few thousand is all you need. I have a YouTube channel with less than five thousand subscribers, and I can make thousands of dollars a month selling my ebooks.

The first step to growing an audience is to start a blog or join social media. For example, if you start a TikTok account and create videos using Excel, you may garner a huge audience.

You can leverage this audience to sell a course. Kat Norton did this when she created Miss Excel.

She grew her TikTok audience to over 900k and later created several Excel online courses.

miss excel

Other creators use LinkedIn, YouTube or X to build their audience for their online course.

When building your audience you also want to solidify your target persona for your online course.

A target persona is an avatar of your ideal customer. Who will buy your course? Gather data about your audience like:

  • Gender, age and location
  • Job title
  • Education level
  • Family status (if relevant)
  • Household income
  • Online behavior (what platform do they hang out on?)
  • Pain points

If you don’t have access to all of this information you can create your brand around this fictitious avatar so that you will eventually track your ideal customer, aka target persona.

Research Analysis

It's time to see what your competitors are doing.

Conduct market research to identify gaps in existing courses and see what potential students are actively seeking. 

For example, suppose you're a nutrition expert and want to create a course around plant-based nutrition. In that case, you must purchase other courses and evaluate their content, structure, and delivery.

  • Course Length: Number of modules and total hours
  • Content Depth: Beginner, intermediate, or advanced
  • Teaching Style: Video lectures, interactive content, quizzes, assignments
  • Course Materials: PDFs, downloadable resources, recipes
  • Price: Cost of the course and any payment plans

From there, you can look at the strengths and weaknesses of each course to see what you can bring to the table. Maybe the courses you viewed showed a lack of depth or avoided any meal-prepping suggestions.

With those ideas, you can build your online course to focus on those gaps, ensuring that an audience wants this information and help.
