How to Build an Online Course -Turn Your Expertise into a Profitable Digital Product

If you’ve been thinking about how to build an online course, now is one of the best times to act. Online courses let you scale your expertise, reach learners beyond your postcode, and—when done well—create a recurring revenue stream. Below I’ll walk you through why digital courses often outperform traditional face-to-face training (with UK-specific evidence), and give a practical, step-by-step blueprint to build an online course that sells.

Why build an online course now (UK evidence that digital wins)

Rigorous reviews and meta-analyses show online and blended learning are at least as effective as face-to-face instruction, and blended approaches often outperform purely classroom formats on learning outcomes. That means you’re not trading quality for scale if you build the course well. Here are a few statistics to keep in mind while considering whether to convert your knowledge into an online course for reselling:

UK Adults
0 %

Several UK studies and industry reviews show that demand for online and blended learning is established and growing. The Learning & Work Institute’s Adult Participation in Learning Survey 2024 found that just over half of UK adults (52%) took part in learning in the last three years — driven largely by an increase in self-directed and online study.

of Organisations
0 %

From an employer perspective, organisations are adopting digital or blended delivery at pace. A 2024 review of learning technologies found that blended learning—which mixes online and in-person elements—has been adopted by roughly 62% of organisations, underlining that digital-first programmes are now mainstream in the workplace.

Potential Students
0 +

Universities and providers are already reaching far beyond campus: UK transnational and distance education enrolled over 600,000 students across undergraduate and postgraduate TNE programmes in 2022–23 — showing the scale you can tap into when you go digital.

Employer savings
up to 0 %

Industry benchmark stats also underline efficiency and ROI. Analyses often quoted in the L&D world show that e-learning can take 40–60% less employee time than equivalent classroom training—helping organisations reduce costs and remove the “time” barrier to learning.

Before you build an online course: validate your idea

Don’t build a full course before you’ve checked demand. Follow these quick validation steps:

Pick your niche

Pick a clear niche and outcome (e.g., “Build a 6-figure freelance content plan in 8 weeks”).

Survey potential

Run a simple survey or LinkedIn poll and a tiny paid ad test to measure interest.

Introductory Pricing

Offer a low-cost pilot (a mini course, workshop or webinar) to a small group and gather feedback.

Competitive research

Check competitive pricing for similar UK offerings and corporate budgets if you plan to sell B2B.

How to build an online course — a practical step-by-step

  • Design outcomes-first. Write 3–5 measurable learning outcomes—what a learner should do after completing your course.
  • Slice the content into small modules. Short, focused lessons improve completion and fit busy schedules (LinkedIn Learning and other UK workplace reports show “lack of time” as a key barrier to upskilling). 
  • Choose the format. Mix short videos (5–12 mins), action worksheets, short quizzes, and one optional live Q&A. Blended formats increase engagement and retention.
  • Record with modest gear. Clean audio (USB mic), a good webcam or smartphone, a lapel mic for mobility, and simple lighting. Script the lesson openings and CTAs.

  • Pick a platform. For consumer sales use marketplaces like Udemy, Teachable, Kajabi or Thinkific (keep in mind that you bring YOUR audience and traffic to them and they own your customer and contact base). For higher ticket or B2B sales, a self-hosted LMS + Stripe or PayPal and a client portal often works better which is what we can help to create for you.
  • Price strategically. Start with an introductory price for early adopters, then test price points; offer payment plans for higher-ticket cohorts.
  • Launch & iterate. Use email, LinkedIn, partnerships, and a repeatable webinar funnel. Collect feedback and refine content, community, and onboarding.

Why learners and employers prefer online courses (UK context)

Flexibility & access

Flexibility & access. Busy UK professionals favour bite-size, on-demand learning rather than day-long classroom events—this directly addresses time barriers to learning.

Scalability & reach

Scalability & reach. A single course can be sold repeatedly across the UK (and internationally) without proportional venue costs—Universities UK TNE data shows how digital delivery expands reach.

Comparable or better learning outcomes

Comparable or better learning outcomes. Meta-analyses find blended/online approaches equal or superior on retention and application, so organisations gain results while saving time and money.

Monetisation & growth: beyond the first sale

  • Sell B2C (one-off courses), B2B (company licences + cohort training), subscriptions (access to all content), or high-ticket cohorts (group coaching + certification).

  • Add certificates, CPD points, or employer-backed endorsements to increase the perceived value.

  • Use affiliates, micro-credentials, and corporate partnerships to scale faster.

Measuring success after you build an online course

Track these KPIs: completion rate, NPS / learner satisfaction, revenue per learner, CAC (cost to acquire a customer), and LTV (lifetime value). Use automated analytics inside your LMS and quick post-course surveys to measure outcome achievement.

Final thought

To build an online course that sells, combine clear outcomes, short focused lessons, and an evidence-backed launch plan. The UK data is clear: learners and employers increasingly prefer digital and blended formats because they scale better, often save time and money, and—when designed properly—deliver equal or better learning outcomes. If you commit to validation, quality content and ongoing iteration, you’ll transform your expertise into a profitable digital product.
