Online Course Creation — How to Create & Sell Courses Online
Online courses are a $300+ billion market. If you have expertise in a topic people want to learn, you can create a course once and sell it for years. Here is how to create and sell your first online course.
The explosion of online learning means people are eager to pay for knowledge. A well-crafted course on a topic like "Investing for Beginners" or "Retirement Planning for Millennials" can generate $10,000-100,000+ per year. The key: teach a specific skill or solve a specific problem. "How to build a dividend portfolio from scratch" sells better than "Introduction to Investing" — specific promises convert better than generic topics.
Choosing Your Course Topic
The best course topics are skills people want to learn and are willing to pay for. Validate your topic before creating anything: search for similar courses on Udemy and Teachable — how many students do they have? Read their reviews — what do students wish was covered better? Search for your topic on Google and YouTube — is there clear demand? Create a survey or poll your email list. Your topic should be specific enough that someone would pay for a shortcut to that knowledge. Finance-specific ideas: "How to Retire Early on a Middle-Class Salary", "Dividend Investing for Passive Income", "Cryptocurrency for Conservative Investors", or "How to Open and Fund Your First IRA".
Creating Your Course
You don't need expensive equipment. A decent USB microphone ($50-150), screen recording software (OBS is free, Screenflow for Mac, Camtasia for Windows), and basic presentation skills are enough to start. Structure your course into modules (5-10 modules) with 3-8 lessons each. Each lesson should be 5-15 minutes — shorter videos have higher completion rates. Start with an outline before recording anything. Film in batches (all module 1 videos, then module 2, etc.). Include downloadable resources: worksheets, checklists, templates, and supplementary reading. These increase perceived value and completion rates. Don't aim for perfection — aim for good enough. Your first course will teach you more than any course creation guide will.
Choosing a Platform
Teachable: Best for premium courses ($50-500+). Full control over pricing, students, and branding. $39/month or 5% + $1 per sale. Udemy: Best for reaching new students. They bring traffic — you bring content. You earn 97% when you drive sales, 37% when Udemy does. Courses priced $12.99-99.99. Highly competitive. Skillshare: Subscription model — you earn based on minutes watched. Best for creative skills (design, photography, writing). Thinkific: Similar to Teachable with more built-in marketing tools. Free plan available. Your own site: Sell via Gumroad, Podia, or your own WordPress/LearnDash site. Highest margins (no platform fees) but you must drive all traffic. Most successful course creators start on Teachable or Udemy and later add a self-hosted option for higher-priced courses.
Marketing Your Course
A great course with no students generates $0. Marketing is half the work. Pre-launch: Build an email list before your course is ready. Offer a free mini-course or checklist related to your topic. Launch strategy: Open cart for a limited time (7-14 days) with an early-bird discount. Create urgency. Content marketing: Write articles and create YouTube videos teaching small pieces of your course material — this builds trust and traffic. Affiliates: Offer 30-50% commission to affiliates who promote your course. Email sequence: Send 5-7 emails during your launch window, each providing value and making the case for your course. Once launched, continue promoting via email and content — evergreen courses sell year-round.
