Marketing Online Courses: A Step-by-Step Guide for Irish Educators and Trainers

Online learning in Ireland has gone from niche to mainstream. Yoga teachers are teaching on Zoom, accountants are running CPD webinars, and universities are offering diplomas you can do entirely from your kitchen table.

But if you’re the one running the courses, the boom isn’t always good news. The competition is fierce. Learners are spoiled for choice. And just when you’ve figured out Facebook Ads, along comes AI, throwing even more content into the mix.

So how do you stand out, build trust, and get paying learners through the door? Let’s break it down step by step – with a few Irish case studies thrown in for good measure.

Step 1: Know Who You’re Teaching

The first step sounds obvious, but it’s the one most trainers skip. If you say “my course is for everyone,” it usually ends up being for no one.

Instead, figure out who you’re really trying to help.

Ask yourself:

• How old are they?
• What stage of life are they in?
• What’s the main problem they’re hoping to solve?
• How do they usually go about learning?

Examples:

• A 35-year-old HR professional in Cork doing CPD hours – they want something accredited, recognised, and time-efficient.
• A Leaving Cert student in Dublin – they’re after affordable, easy-to-digest revision sessions, probably found on TikTok or YouTube.
• A small business owner in Galway – they want practical know-how, like how to do VAT returns without pulling their hair out.

Pro tip: Ring three past students and ask why they signed up. Their answers will often surprise you – and they’ll give you the exact words to use in your marketing.

AI watch-out: AI persona generators often spit out bland characters like “Jane, 30, enjoys coffee and Instagram.” That’s no use. Talk to real Irish learners. They’ll tell you things AI never could – like “I signed up because my cousin recommended it” or “I wanted something that actually referenced Revenue rules, not just generic theory.”

Step 2: Be Clear on Why Your Course Matters

People don’t buy information anymore. There’s already more free information online than anyone could ever use. What they’re paying for is:

• Guidance – learning from someone who knows the ropes.
• Accountability – someone to keep them on track.
• Recognition – certificates or CPD points that mean something.
• Community – a group of people on the same journey.

So instead of saying:
“Learn Excel online”

Try:
“Get confident running your family business accounts in Excel in just 4 weeks – with live Irish support and real case examples.”

It’s the difference between being “just another online course” and being the one that actually solves their problem.

Mini-story: A trainer I know in Cork thought his marketing students wanted “digital marketing knowledge.” When he asked them, it turned out they wanted “the confidence to promote their café without wasting money.” Once he shifted the wording on his website to reflect that, his sign-ups doubled.

Step 3: Make Your Website Do the Work

Think of your website as both your shop window and your sales assistant. It has to look good and guide people to buy.

Every course should have its own page with:

• A plain-English description (“This course will help you…”).
• Who it’s for and who it’s not for.
• The results people can expect.
• Reviews, testimonials, or even screenshots of happy students.
• A clear “Sign Up” button.

And keep sign-up simple – no endless forms. If it takes more than two clicks, you’ll lose people.

SEO tip: Optimise your pages for local searches. “Online bookkeeping course Ireland” will bring you learners. “Bookkeeping course” will drown you in global competition.

AI watch-out: A lot of AI website builders churn out sites that look identical. Irish learners notice when something feels generic. Use AI for speed, but customise heavily so your site reflects you.

Step 4: Content That Feels Real

Here’s where most online trainers trip up. They’ve heard content marketing is important, so they churn out blog after blog with titles like “Top 10 Tips for Students”. The problem? It reads like wallpaper. Learners skim, yawn, and click away.

What works is content that feels human, useful, and rooted in real Irish life. It should sound like you’re talking to someone over a cup of tea, not like you’re handing in a school essay.

Sample Content Ideas

1. Student Stories
   • Instead of: “Our students pass exams.”
   • Try: “Mary from Limerick signed up for our bookkeeping bootcamp because she couldn’t make sense of VAT. Within three months, she was filing returns for her own café — without having to pay an accountant €300 a pop. Here’s how she did it.”
2. People trust people. A short story like this is ten times more convincing than any ad.

1. Local Context Blogs
   • Topic: “How Revenue’s latest update impacts small businesses in Ireland”
   • Angle: Explain it in plain English, with a real-world example.
   • Sample intro:
     “If you’re running a small shop in Cork or Galway, Revenue’s new update on VAT thresholds might look like gibberish. Here’s what it actually means for your invoices — and how you can stay on the right side of the rules without a headache.”
2. This works because it’s Irish-specific. Your learners won’t find it in a generic YouTube video from the States.

1. Free Checklists or Mini-Guides
   Create a simple PDF with practical steps. Example:
   • “5 Mistakes Irish SMEs Make With Bookkeeping”
   • “The Leaving Cert English Essay Checklist”
   • “3 Things to Do Before You Launch Your Google Ads in Ireland”
2. These can be used as lead magnets — people swap their email for the freebie, and suddenly you’ve got them on your list.

1. Short Video Tips
   Irish learners love short, snappy videos that explain things quickly. Example:
   • A 60-second Instagram reel: “Here’s how to set up an Excel formula to track your weekly sales (perfect if you’re a small café owner).”
   • A TikTok for students: “Three revision hacks I wish I knew before my Leaving Cert.”
2. They don’t need to be fancy. A phone camera, good light, and your own personality are enough.

1. Behind-the-Scenes Content
   Let people see the human side. Example:
   • A post with a photo of you setting up your Zoom class, captioned: “Testing the slides for tonight’s session — always a mix of nerves and excitement!”
   • A blog about your own learning journey: “Why I failed my first exam and what it taught me about teaching others.”
2. This builds trust because learners see you’re a real person, not a faceless “brand.”

Mini-Case Study

A CPD training provider in Dublin started creating two-minute “plain English” explainers about CRO filing changes. Nothing polished — just a quick video from their office. Within weeks, accountants started sharing the clips on LinkedIn. Those free videos became their best lead magnet, bringing in hundreds of new learners without a cent spent on ads.

AI Angle

AI can help with outlines or even generating FAQs, but don’t let it take over your tone. Learners can spot when something’s been spat out by a robot. The trick is to let AI do the heavy lifting on structure, while you add the Irish context, the humour, and the human touch.

Example:

• AI might draft “10 Tips for Excel.”
• You add: “Tip 7: If you’re running a café in Dublin, use this formula to track daily coffee sales — it’ll save you counting receipts at midnight.”

That’s the difference between forgettable content and content that feels real.

Step 5: Ads – Start Small, Learn Fast

Advertising is one of the fastest ways to get eyeballs on your course — but it’s also the quickest way to burn through money if you’re not careful. Too many trainers in Ireland either avoid ads altogether (“sure, it’s too expensive”) or they throw €1,000 at Facebook in one go and wonder why they didn’t get results.

The secret is to start small, measure everything, and scale only when you know what works.

Where to Advertise

1. Google Ads (Search)
   • Best for people actively looking for you.
   • Example keywords:
     • “Online bookkeeping course Ireland”
     • “CPD accountancy training Dublin”
     • “Excel training course Cork”
   • Why it works: These learners are motivated. They’re not scrolling aimlessly; they’re already searching for what you offer.
2. Sample ad copy:
   • Headline: “Complete Your CPD Hours Online – Irish Accountants Teaching”
   • Description: “12 accredited CPD hours. Flexible online learning. Enrol today and finish your hours before year-end.”

1. Facebook & Instagram Ads
   • Great for awareness, storytelling, and more casual courses.
   • Example: A photography trainer in Galway runs Instagram story ads showing before-and-after shots taken by past students.
   • Why it works: The ads are visual, quick to digest, and spark the thought: “I could do that too.”
2. Sample ad idea:
   • Video of you saying: “Want to finally crack Excel formulas? In my 4-week course, I’ll walk you through it step by step, with Irish examples. No jargon, no stress.”

1. LinkedIn Ads
   • More expensive but gold for corporate or CPD training.
   • Example: A Dublin-based CPD provider runs LinkedIn ads targeting HR managers in firms with 50+ staff. The message? “Bulk CPD packages for your team – finish all hours by year-end without leaving the office.”
2. Why it works: HR managers aren’t browsing TikTok for training — but they are on LinkedIn looking for practical solutions.

1. YouTube Ads
   • Brilliant for credibility if you have video content.
   • Example: A Leaving Cert tutor runs 15-second ads before study-related videos. The ad simply says: “Struggling with English essays? Join my free webinar this Saturday – sign up now.”

How Much to Spend

Don’t think you need thousands. You can test campaigns from as little as €10 a day. Start with €300–€500 for one course, one audience, one platform. See what happens.

Tip: Don’t advertise all your courses at once. Pick your most popular or easiest-to-sell course first, nail the messaging, then scale.

Common Mistakes Trainers Make

• Being too vague: Ads saying “Learn online” don’t work. Ads saying “Finish your CPD hours this month” do.
• Targeting too broad: Advertising to “all of Ireland” is wasteful. Narrow it to job titles, age, or even location if relevant.
• Ignoring follow-up: Ads might get clicks, but if your landing page is confusing or your email sequence is weak, people won’t buy.

Mini-Story

A trainer in Cork launched a “Digital Skills for Small Business Owners” course. His first ad campaign was €1,000 on Facebook with the headline: “Learn digital marketing online.” Result? Three sign-ups.

He regrouped. Second campaign: €300, focused just on Cork business owners, headline: “Promote your café or salon online without wasting money – 4-week course designed for small Irish businesses.”

Result? Twenty sign-ups. Less money, more results. Why? Because the message spoke directly to the right people.

AI Angle

AI tools can help you:

• Brainstorm ad headlines.
• Suggest keywords.
• Test different ad variations quickly.

But here’s the catch: if you rely on AI word-for-word, your ads will look identical to everyone else’s. Irish audiences especially can smell “cookie-cutter” ads.

The trick is to use AI for speed, then add your own personality, Irish references, and human touch.

Example: AI might suggest: “Improve your Excel skills today.”
You could humanise it into: “Tired of fighting with Excel formulas? Learn how to track your café’s sales in just 4 weeks – no jargon, just plain English.”

Step 6: Email – The Old Reliable

Social media platforms change the rules all the time. Email doesn’t. It’s still the best way to build a direct connection.

Start building your list from day one. Offer a freebie – a guide, a short course, or a checklist.

Then:

• Send useful tips 70% of the time, offers 30%.
• Segment your list. CPD learners don’t want the same emails as hobby learners.
• Add personal touches. Even a “Hi John, hope the rain isn’t too bad in Cork this week” makes a difference.

Mini-story: One trainer in Galway added a weekly email tip called “One-Minute Monday.” It was always short, practical, and personal. People started forwarding them to colleagues, and before long, her list doubled – at no extra cost.

AI angle: AI can help draft emails, but it can’t replace your personal voice. Use it for ideas, but always rewrite in your own style.

Step 7: Pick Your Social Media Battles

A common mistake many course providers make is thinking they need to be everywhere at once. They sign up for TikTok, Instagram, Facebook, LinkedIn, and YouTube, post randomly for a few weeks, then give up when nothing happens.

The truth? You don’t need to be on every platform. You just need to be where your learners actually spend their time.

Matching Platforms to Learners

1. TikTok & Instagram
   • Best for youth-focused or creative courses.
   • Example: A Leaving Cert maths tutor posts 30-second videos solving one tricky problem at a time. Each ends with: “Want the full revision course? Link in bio.”
   • Another example: A yoga teacher in Galway shares morning routines as reels, with captions like “5 minutes to reset before work.”
2. Why it works: These platforms thrive on short, snappy, visual content. Perfect for learners scrolling on the bus.

1. LinkedIn
   • The go-to for corporate training, CPD, or professional development.
   • Example: An accountancy trainer shares a post:
     “Revenue’s latest VAT update explained in 90 seconds. (And yes, it matters if you run a small Irish business.)”
     – then links to their paid CPD course.
   • Another example: A leadership coach posts a story about a tough workplace situation and how their course helps managers handle it.
2. Why it works: LinkedIn users are already in a “professional learning” mindset.

1. Facebook
   • Still strong in Ireland, especially with older demographics.
   • Example: An Excel trainer runs a local Facebook group called “Small Business Tools Ireland” where they share weekly tips. They then promote their paid course directly in the group.
2. Why it works: Facebook groups build community and trust.

1. YouTube
   • Brilliant for technical or deep-dive subjects.
   • Example: A coding trainer uploads tutorials like “How to build a website in 10 minutes (Irish hosting example).”
   • Another: A CPD provider uploads “5-minute explainers” on accounting standards.
2. Why it works: YouTube is the second-biggest search engine after Google. Learners go there actively looking for help.

Post Samples

Here are a few posts trainers could run straight away:

• Instagram/TikTok:
  Short video: “3 mistakes people make in their first bookkeeping exam (and how to avoid them).”
• LinkedIn:
  Text post:
  “Most Irish accountants wait until November to cram CPD hours. Don’t be that person. We’ve built a flexible course to finish early and stress-free. Details below.”
• YouTube:
  Tutorial: “How to calculate VAT in Ireland – explained step by step (2025 rules).”

Common Social Mistakes

• Trying to sell too hard: Social media works best when 80% of your posts are value, 20% are offers.
• Copy-pasting across platforms: What works on LinkedIn will flop on TikTok.
• Going silent: Posting three times a day for two weeks, then vanishing for a month. Consistency beats volume every time.

Mini-Story

A Dublin-based life coach was trying to grow on Instagram. She posted polished motivational quotes daily, but got little traction. When she switched to recording short, casual videos on her phone — talking about real struggles like procrastination, with her dog wandering into frame — her engagement tripled.

Lesson? Learners don’t want perfection. They want personality.

AI Angle

AI can help you:

• Generate post ideas quickly.
• Draft captions.
• Resize content into different formats.

But the risk? Ending up with posts that all sound the same. If every Irish trainer used the same AI tool, the feeds would be flooded with identical content.

The solution: Use AI for structure, then add your own voice, humour, and Irish context.

Example:

• AI caption: “Boost your productivity with these top Excel tips.”
• Humanised version: “Ever found yourself screaming at Excel on a Sunday night? Here’s a simple formula that’ll save you hours (and your sanity).”

Step 8: Work With Partners

No matter how good your ads are, nothing beats a trusted recommendation. In Ireland, we’re still a word-of-mouth nation at heart. That’s why partnerships can be one of the strongest marketing moves for trainers — they get you in front of ready-made audiences who already trust the referrer.

Instead of doing everything yourself, think: Who already has my learners’ attention?

Types of Partnerships

1. Corporate Partnerships
   • Offer bulk packages to companies.
   • Example: An accountancy CPD provider sells 50 course seats at a discount to a Dublin firm. HR is delighted because staff get their hours done in one go, and the trainer gets guaranteed enrolments.
   • Message to HR: “Keep your accountants compliant without scrambling in November — we’ll handle the CPD.”

1. Educational Partnerships
   • Work with ETBs, local colleges, or libraries.
   • Example: A digital marketing trainer partners with Kildare ETB to run an introductory online course for SMEs. The ETB covers part of the cost, making it more accessible to learners.
   • Another example: A library in Galway hosts “study evenings” with a Leaving Cert revision coach. The students then sign up for full online packages.

1. Industry Bodies
   • Partner with associations like ISME, IBEC, or trade unions.
   • Example: A health & safety trainer offers discounted online modules to members of a trade body. In return, the body promotes the course to thousands of members through its newsletter.

1. Influencers and Micro-Influencers
   • Not just TikTok stars — but local professionals with engaged followings.
   • Example: A career coach partners with an Irish LinkedIn influencer who posts about job hunting. They do a live Q&A together, and the coach gets exposed to thousands of job-seekers.
   • Another: A fitness trainer partners with a GAA player who shares their online course to their Instagram followers.

1. Affiliate Programmes
   • Offer a small commission (10–20%) to people who refer learners.
   • Example: A coding trainer sets up an affiliate link for past students. Every time they refer a friend who signs up, they get €20 off their next course.

Sample Collaboration Ideas

• Webinars: Co-host a free webinar with a partner. Example: “How to grow your café’s sales using Instagram” – presented by a trainer + local business association.
• Discount Bundles: Offer “partner-only” discounts. Example: “Chamber of Commerce members get 15% off our leadership course.”
• Guest Content: Write a guest article for an industry body’s newsletter. Example: “5 bookkeeping mistakes Irish SMEs make.”
• Joint Ads: Split ad costs with a partner to reach a bigger audience.

Common Mistakes

• Being too broad: Approaching 20 random companies with the same generic email rarely works. Partnerships work best when tailored.
• One-sided offers: Don’t just ask, “Can you promote me?” Offer something in return — discounts, joint content, or added value.
• No follow-up: Many trainers land one partnership, get a spike of sign-ups, then let the relationship fizzle out. Partnerships need ongoing attention.

Mini-Story

A training provider in Limerick ran leadership courses. For months, they relied only on ads. Results were patchy. Then they partnered with their local Chamber of Commerce, offering a 20% discount for members.

The Chamber promoted it in their newsletter. Within two weeks, the trainer had more sign-ups than in the previous three months combined. Even better, corporate clients started enquiring about bulk training.

Lesson? One good partnership can be worth more than months of ads.

AI Angle

AI won’t build relationships for you. But it can help with:

• Drafting outreach emails.
• Researching potential partners.
• Creating simple affiliate dashboards.

The risk? Sending cold, robotic emails that read like spam. 

Step 9: Track, Listen, Improve

One of the biggest mistakes course providers make is running ads, posting on social media, or sending emails — and then never checking what actually worked. It’s like teaching a class with your eyes closed.

Marketing is never a “set and forget” game. To keep filling seats, you need to measure what’s happening, listen to learners, and use those insights to improve your next campaign.

What to Track

1. Website Traffic
   • How many people are landing on your course pages?
   • Where are they coming from (Google search, social media, email, ads)?
   • Which pages make them stay, and which ones lose them?
2. Example: A Galway trainer saw lots of clicks on their “Excel for SMEs” page but almost no sign-ups. On review, the sign-up form was asking for too much information. They simplified it, and conversions doubled.

1. Ad Performance
   • Don’t just count clicks — track conversions (who actually signed up).
   • Test variations of headlines, images, and targeting.
   • Kill underperforming ads quickly, and reinvest in the ones that work.
2. Example: A Dublin CPD provider ran two ads:
   • “Complete your CPD hours online.”
   • “Finish your CPD before Christmas without leaving your desk.”
     The second ad got twice the enrolments, even though the budget was the same.

1. Email Engagement
   • Open rates: Are people even reading your emails?
   • Click-through rates: Are they clicking your links?
   • Replies: Do they feel comfortable enough to hit “reply” and ask questions?
2. A trainer in Cork noticed open rates dipped whenever subject lines were too “salesy.” Switching to friendlier subject lines like “Still fighting with Excel?” boosted opens by 20%.

1. Learner Feedback
   • Surveys after each course: “What nearly stopped you from signing up?” / “What’s the best thing you got out of this?”
   • Informal check-ins: Even one or two phone calls with past learners can reveal gold.
2. Example: One Leaving Cert tutor discovered students didn’t care about “comprehensive notes” (which he kept highlighting). What they really wanted was confidence before exams. He shifted his marketing to focus on confidence, and sign-ups jumped.

AI-Powered Reporting

Here’s where things get exciting. AI can turn a sea of numbers into clear insights — fast.

1. Dashboards that Explain Themselves
   Tools like AgencyAnalytics, Looker Studio, or even AI-driven dashboards can automatically pull data from Google Ads, Facebook, and your website. Instead of drowning in spreadsheets, you see plain-English summaries like:
   • “Most of your enrolments came from LinkedIn ads last month.”
   • “Your Excel course page is converting twice as well as your bookkeeping page.”

1. Predictive Insights
   AI can flag trends before you notice them. For example:
   • “Learners who download your free checklist are twice as likely to buy a paid course within 30 days.”
   • “Evening ads (7–9 pm) are converting 40% better than morning ads.”
2. That means you can adjust campaigns on the fly instead of wasting money.

1. Sentiment Analysis
   Imagine collecting student feedback and letting AI scan it for themes. Instead of reading through 200 survey responses manually, the AI can say:
   • “70% of learners mention ‘confidence’ as a key outcome.”
   • “30% struggled with the sign-up process.”
2. This helps you fix pain points quickly.

Common Mistakes in Tracking

• Looking only at vanity metrics: Likes and clicks feel nice, but they don’t pay the bills. Focus on enrolments and revenue.
• Not linking data to action: Seeing “low conversions” is useless unless you ask why.
• Overcomplicating tools: Don’t set up 10 dashboards you never look at. One good report that you check weekly is better.

Mini-Story

A Dublin training company relied on Facebook likes as their success metric. They had thousands of likes but few sign-ups. After switching to AI-powered reporting, they realised 80% of their actual sales were coming from Google Ads, not Facebook.

They reallocated budget accordingly — and within three months, enrolments doubled without increasing total ad spend.

AI Angle in Practice

AI isn’t there to replace your judgment. It’s there to highlight patterns so you can make smarter decisions.

Think of it as having a junior analyst working 24/7:

• It crunches the numbers.
• You decide what actions to take.

The winning formula is data + human sense. AI can say “evening ads work better.” But you’ll know that’s because learners are finishing dinner, settling down, and finally opening their laptops.

Case Study 1: Accountancy CPD Courses

A Dublin-based provider launched CPD courses for accountants. Their first ads said: “12 CPD hours available online.” Result? Crickets.

When they shifted the message to:

• “Finish your CPD hours before year-end without leaving your desk”
• “Irish accountants teaching Irish rules”

— things changed.

They invested in LinkedIn Ads, wrote short blogs about real Irish tax cases, and added testimonials. Within six months, enrolments doubled, and entire firms started buying team packages.

Case Study 2: Multi-Course Training Provider

An Irish provider offered a mix of digital marketing, Excel, and leadership training. Their site looked messy, and their ads were generic.

The fix:

• Each course got its own proper landing page.
• Email funnels were split by interest.
• Ads were targeted per subject.
• They partnered with their local Chamber of Commerce.

Within a year, corporate training enquiries rose by 60%, and their reputation shifted from “cheap courses” to “trusted partner.”

The AI Question

AI is both a friend and a foe for online education.

Risks:

• The market is flooded with low-cost, AI-built courses.
• Learners can’t always tell what’s genuine.
• Some will say: “Why pay €200 when ChatGPT can explain it?”

Opportunities:

• Use AI to handle admin, draft quizzes, and tidy up.
• Double down on the human side: case studies, mentoring, cultural context.
• Build communities AI can’t replicate.

The real win? Position yourself as the trustworthy human voice in a noisy, automated market.

How Salt Marketing Can Help You

• Simplifying your sign-up journey on your website.
• Reworking your Google Ads so you stop wasting money on the wrong clicks.
• Bringing consistency and personality to your social media.
• Setting up marketing automation so follow-ups happen while you sleep.

FAQs

How do I market an online course in Ireland?

Start by defining your learner, build a simple sales funnel, and use a mix of ads, content, and email marketing. Irish examples and context always perform better.

Are paid ads worth it for online courses?

Yes, but only if you start small and track results. Google Ads work best for active learners, while Facebook/Instagram are great for awareness.

How do I stand out against free AI-generated courses?

Focus on what AI can’t offer: live support, Irish-specific content, accountability, and community.

Should I use AI to create my course?

AI can help with outlines and quizzes, but your voice and expertise should stay central. Otherwise, your course will sound like every other generic one.

What’s the cheapest way to promote a new course?

Email marketing and partnerships. Start building your list early, and talk to local businesses, libraries, or chambers for exposure.
