Should You Take a Short Marketing Course? Complete Decision Framework

Last updated: April 2026 · Written by 20 Minute Marketing · 8 min read

You should take a short marketing course if you can commit 5–10 hours per week and are willing to implement what you learn. The course teaches the skills; your action determines the results. The better question isn’t “should I take a course?” — it’s “will I actually implement this?”

Not everyone should take a short marketing course. Some people are better off hiring an agency. Some should wait. Some should focus on something else entirely. This guide is an honest decision framework to help you figure out which camp you’re in — without the sales pitch.

The Decision Framework: 5 Questions to Answer Honestly

Question 1: Do You Actually Have the Time?

Short marketing courses don’t require 40 hours a week — but they do require consistent, protected time. The minimum viable commitment is around 5 hours per week for 8–16 weeks. That could be a daily 20-minute lesson plus 40 minutes of implementation. If you genuinely cannot carve out 5 hours per week, a course is not the right choice right now. Fragmented time (commute, lunch breaks, early mornings) does count — the 20-minute lesson format is specifically designed for this.

Question 2: Are You Willing to Implement — Not Just Learn?

This is the most important question. Research consistently shows that fewer than 15% of online course learners finish what they start, and even fewer implement what they learn. The course is 20% of the equation — your implementation is 80%. If you’re honest with yourself and know you tend to start courses and not finish them, you are better off hiring someone to execute than paying for knowledge you won’t apply.

Question 3: Do You Need Results Now, or Can You Wait?

Short courses accelerate learning significantly compared to self-teaching, but they are not instant. Expect 3–6 months before your marketing produces consistent, measurable results. If your business is in crisis and needs leads in the next 30 days, a course is not the right tool — a Google Ads campaign managed by a specialist is. If you have a 3–6 month window to build capability, a course delivers far better long-term ROI.

Question 4: Is This Course Relevant to Your Market?

The majority of digital marketing courses are built for the US or UK market. NZ small businesses face different consumer behaviour, different platforms (Google dominates search here more than in the US), different compliance requirements (SPAM Act 2003, ACCC guidelines, Kiwi Privacy Act), and different seasonal rhythms. A course built on Kiwi examples is not a nice-to-have — it is a meaningful differentiator in whether you can actually implement what you learn.

Question 5: Are You Willing to Own Your Marketing Long-Term?

A course is an investment in building your own capability — marketing knowledge you own permanently, not rent monthly. If your goal is to eventually hand off all marketing to someone else and never think about it again, a course is not a good fit. If you want to understand your marketing well enough to direct it intelligently — even if you hire help later — a course is the foundation.

What Short Marketing Courses Actually Deliver

What they do:

• Teach practical, implementable skills
• Provide structured frameworks and templates
• Accelerate learning dramatically vs self-teaching
• Build genuine marketing confidence
• Deliver far better value per dollar than agency retainers

What they don’t do:

• Execute the work for you
• Deliver results if you don’t implement
• Replace real-world experience
• Work overnight — marketing is a compounding skill

Frequently Asked Questions

Is a short marketing course worth it for a small business owner?

For most small business owners who are willing to implement, yes — significantly. The ROI calculation is straightforward: a $49–$500 course that saves you $3,000 per month in agency fees and helps you generate one additional client per month pays for itself within weeks. The constraint is always implementation, not the course quality.

How much time do I need to complete a short marketing course?

The 20 Minute Marketing Essentials Course is structured around 20-minute daily lessons, meaning you can progress through the core material in under an hour a day. Most learners complete the foundational modules in 4–6 weeks with consistent daily engagement. Implementation time on top of learning adds another 2–4 hours per week.

Should I hire an agency or take a marketing course?

If you have $3,000–$8,000 per month available and need results immediately, an agency is the faster path. If you want to build in-house capability and understand your own marketing, a course is the better long-term investment. Many business owners find the ideal approach is to complete a course first, then use an agency for execution — giving them the knowledge to brief and evaluate the agency effectively.

What happens if I start a short course and don’t finish it?

Even partial completion delivers value. If you complete 30% of a well-structured course, you will have learned enough to implement at least one meaningful marketing strategy for your business. The worst outcome is learning nothing — but even one implemented strategy that generates an additional enquiry per week changes the economics of the investment completely.
