Google Ads vs LinkedIn: London Online Course Ads

Right, let's get one thing straight. Asking whether you should use Google Ads or LinkedIn Ads for your online course in London is the wrong question. It's like asking a builder if they prefer a hammer or a saw. They're both essential tools, but you'd be a mug to use a saw to knock in a nail. The real question is what job are you trying to do right now? Are you trying to find Londoners who are actively searching for a solution to a problem your course solves, or are you trying to get your course in front of the perfect professional persona who doesn't even know they need it yet? One is about capturing intent, the other is about creating it. Get that right, and you're halfway there.

Most course creators in the UK burn through their cash because they jump straight to ads without a validated offer. An ad's only job is to amplify what's already working. If you can't sell your course organically to your existing network or audience, paying to send strangers to it will just make you go broke faster. Before you even think about spending a single pound on ads, you need proof that people actually want what you're selling and are willing to pay for it. Pouring ad spend into an unproven offer is like trying to fill a leaky bucket. Fix the bucket first.

So, Google Ads or LinkedIn Ads? What's the real difference for my London course?

This is where we separate the pros from the amateurs. It’s not a simple choice, it’s a strategic one based on who you're selling to and what they're thinking.

Google Ads is for capturing active demand. Think of it as putting a stall right in the middle of a market where people are already shouting for what you sell. These are people in London typing things like "data analysis course for finance professionals UK", "learn python london", or "project management certification online". They have a problem, they know it, and they are actively looking for the solution. This is bottom-of-the-funnel, high-intent traffic. It's often the most profitable place to start because the audience has already qualified itself.

The downside? It's a bidding war. In a competitive market like London, you're up against every other university, bootcamp, and online provider fighting for those same keywords. We've seen CPCs for education-related keywords in the UK range from £2 to over £15 for highly competitive terms. It's expensive, but if your course has a good price point and your sales page converts, it can deliver an immediate return. If you're struggling with this, our guide on mastering Google Ads for selling courses in London is a good starting point.

LinkedIn Ads is for creating demand within a specific persona. This is completely different. Here, you're not finding people who are searching for you. You're finding the exact people who *should* be your customers and interrupting their day with a compelling reason to pay attention. You can target people in London with laser precision: Marketing Managers at FTSE 100 companies, Software Engineers with 5-10 years of experience working in Shoreditch, or newly promoted VPs in finance working in Canary Wharf. The targeting is unbelievably powerful for B2B or prosumer courses.

The catch is that these people are not actively looking for a course. They're scrolling through their feed, connecting with colleagues, and reading industry news. Your ad needs to be good enough to stop them in their tracks. It has to diagnose a pain they might not have even articulated yet and present your course as the antidote. It's a much slower burn. Leads from LinkedIn are often more expensive on paper. However, on one B2B campaign we worked on, we saw costs of around $22 (£17-£18) per lead, and the potential quality and lifetime value of that customer can be much, much higher. For a deep dive, you should probably read our playbook on using LinkedIn Ads for UK education.

So, which one first? I'd almost always start with Google Ads. Prove you can convert the "easy" traffic—the people already looking for you. Once that's profitable, you can use those profits to fund the more complex, brand-building work of creating demand on LinkedIn.

Your Offer is The Problem, Not Your Ads

Let me be brutally honest. The biggest reason ads fail for course creators isn't the targeting, the platform, or the ad copy. It's the offer. Sending a cold prospect from an ad straight to a page that says "Buy my £2,000 course" is insane. It's like walking up to a stranger in a pub and asking them to marry you. You haven't earned the right to ask for the sale yet.

You need to change your Call to Action from "Buy Now" to something that offers immense value for free. You must solve a small piece of their problem upfront to prove you can solve the whole thing. This is non-negotiable.

Good offers for online courses:

• -> A Live Webinar: "Join my free 60-minute masterclass on how London finance professionals can use Python to automate their reporting. I'll show you 3 scripts you can use tomorrow."
• -> A Free Module: "Get instant access to the first module of my 'Certified Project Manager' course. You'll learn the complete framework for scoping a project successfully."
• -> An Interactive Tool or Checklist: "Use our free career calculator to see how a digital marketing qualification could increase your salary in the London tech scene."

This approach does two things. First, it dramatically lowers the barrier to entry, so your cost per lead will plummet. Second, it gives you their email address, which is the most valuable asset you have. Now you can build a relationship, provide more value, and nurture them towards a sale over days or weeks. This is the funnel that actually works.

How much should I actually be spending on ads in London?

This isn't a "how long is a piece of string" question. There's a mathematical answer, but it requires you to know your numbers. The most important metric isn't your ad budget; it's your maximum affordable Cost Per Acquisition (CPA). How much can you afford to spend to get one new student?

Let’s do some back-of-the-envelope maths. Say your course is £1,500. A healthy business model would aim to spend no more than a third of the product price on acquiring a customer. So, your target CPA is £500.

Now, let's work backwards. If your webinar landing page converts visitors into leads at 20% (which is pretty good), and your email sequence converts those leads into customers at 5% (also decent), you can figure out your budget. To get one customer, you need 20 leads (1 / 0.05). To get 20 leads, you need 100 clicks to your landing page (20 / 0.20). So, to get one £1,500 sale, you need to buy 100 clicks. Since your max CPA is £500, you can afford to pay up to £5 per click (£500 / 100 clicks). That's your target.

If clicks on Google or LinkedIn are costing you more than £5, you've got a problem. Either your ad creative isn't good enough, your targeting is off, or your landing page isn't converting well enough. Don't just throw more money at it. Fix the broken part of the system. I remember one elearning client we worked with, we managed to take their cost per signup from a painful amount down to under £2, purely by optimising their funnel and targeting. The budget is an output, not an input.

What Kind of Ad Creative Actually Resonates with Londoners?

The London audience is sophisticated, busy, and cynical. They've seen it all before. Generic, stock-photo-heavy ads will be ignored. Your creative needs to be direct, authentic, and value-driven. Don't sell the features of your course; sell the outcome. Sell the transformation.

Use the Before-After-Bridge framework.

• Before: Paint a vivid picture of their current pain. "Stuck in a dead-end finance job in the City, running the same Excel reports day after day?"
• After: Describe the dream outcome. "Imagine leading data-driven strategy meetings, building predictive models, and becoming the most valuable person in your team."
• Bridge: Introduce your course as the clear, simple path from A to B. "Our 12-week 'Data Science for Bankers' course is the bridge. No fluff, just the practical Python and SQL skills you need."

For creative formats, video is king, but it doesn't need to be a Hollywood production. In fact, slick, overproduced videos can feel inauthentic. A simple, well-lit video of you talking directly to the camera, explaining the problem you solve, can be incredibly effective. User-generated content (UGC) style videos, like testimonials from past London-based students, are pure gold. We had one SaaS client see incredible results just by switching to more authentic, UGC-style creatives.

Your ad copy needs to be punchy and respect their time. Get to the point quickly. And please, for the love of god, make sure your spelling and grammar are perfect. A typo is a credibility killer. This isn't just about ads, it's about your entire brand perception. Crafting the right message is an art, and if you're struggling, it's worth checking out a blueprint for UK online course ad creative.

And once you have those leads, you can't just abandon them. A crucial part of the strategy is using retargeting to stay top-of-mind. This means showing different, targeted ads to people who have visited your site or watched your videos. For a deeper look into this, we've put together a complete guide on retargeting for online courses that you should definitely read.

This sounds like a lot of work. When should I consider getting help?

Look, you absolutely can learn to do all of this yourself. But you need to be honest about what business you're in. Are you in the business of creating and teaching amazing courses, or are you in the business of becoming a full-time digital marketer? Because doing this properly is a full-time job. It's a constantly moving target of platform updates, creative testing, and data analysis.

You might want to consider expert help if:

• -> You're spending more than £1,000-£2,000 a month and aren't seeing a clear return. At this level, an expert can often save you more than their fee just by eliminating wasted spend.
• -> You're a subject matter expert, not a marketing expert. Your time is best spent improving your course and teaching your students, not fiddling with ad campaign settings.
• -> You've hit a plateau. Your ads used to work, but now they've stopped performing and you don't know why. An outside perspective can often spot the problem quickly.
• -> You want to scale aggressively. Going from £2k/month to £20k/month in ad spend without breaking your funnel requires deep expertise. One of our course clients managed to generate $115k in revenue in just six weeks once we scaled their campaigns. That kind of growth doesn't happen by accident.

I've detailed my main recommendations for you below:

Choosing an agency or consultant, especially in a crowded place like London, can feel like navigating a minefield. Look for genuine specialists who can show you case studies relevant to your niche – selling courses or eLearning. Ask them to walk you through their strategy for your specific business. If they just talk about clicks and impressions, run away. If they start asking smart questions about your customer lifetime value, your offer, and your funnel, you might be onto a winner.

If you're serious about growing your online course business and want a second pair of expert eyes on your strategy, we offer a completely free, no-obligation initial consultation. We'll review your current setup and give you actionable advice you can implement straight away. It's a chance to get a taste of the expertise we bring to the table.
