Google Ads UK: The Ultimate Agency Hiring Guide

Right then. So you're selling an online course in the UK and your enrolment numbers are flatlining. You've probably poured your heart and soul into creating something brilliant, but the students just aren't coming in as fast as you'd like. Now you're thinking a Google Ads agency is the magic bullet. I get it. It's a crowded market out there, and you need an edge.

But here’s a bit of tough love to start with: hiring just any old agency to 'run some ads' is probably the fastest way to set fire to a big pile of cash. I've seen it happen dozens of times. A course creator with a fantastic product gets promised the world by a slick salesperson, spends thousands on ads, and ends up with a handful of expensive leads and a load of frustration. The problem isn't that Google Ads doesn't work for courses—it absolutely can, we've generated hundreds of thousands in revenue and tens of thousands of signups for eLearning clients. The problem is that most people, and frankly most agencies, are looking at it all wrong.

They think the ad is the most important part. It's not. The ad is just the front door. If the hallway is a mess, the rooms are cluttered, and the price is written on a soggy napkin, no one's going to stick around to buy the house, no matter how nice the door is. Your entire student journey, from the moment they see your ad to the second they get their welcome email, is one single system. A great agency understands this. A bog-standard one doesn't. This guide is about how to tell the difference and find a true partner who can actually help you scale, not just a button-pusher who will burn your budget.

So, why aren't my ads working in the first place?

Before you even think about hiring someone, you need to understand the likely culprits. When a course creator comes to us with campaigns that are failing, it's almost never just one thing. It's usually a combination of issues that create a leaky bucket. You pour budget in the top, and it just drains away before you get any enrolments out the bottom.

The most common failure point I see is a complete mismatch between the ad and the landing page. The ad promises a life-changing transformation, a new career, a mastery of a new skill. The user clicks, full of hope, and lands on a page that looks like it was designed in 2005, with confusing text, no clear call-to-action, and a stock photo of some people smiling at a laptop. The disconnect is jarring. It breaks trust instantly. All that money you just spent on the click? Wasted.

Another classic is the offer itself. A lot of founders think their course is so good that just putting an "Enrol Now" button with a hefty price tag is enough. For a cold audience that's never heard of you before? That's a massive ask. It's like asking someone to marry you on the first date. You need to build trust and demonstrate value first. Maybe you offer a free module, a taster webinar, or a detailed downloadable guide. A good agency will help you brainstorm and test these 'low-friction' offers to get potential students into your world before asking for their credit card details. If an agency doesn't talk about optimising your offer, that's a massive red flag. They're focused on their bit (the ads), not your bit (the revenue).

I remember one client who came to us with a great product, but their conversions were lacking. There was a massive drop-off in their funnel. Their ads were getting clicks, but no one was buying. We took one look at their page and saw the problem. They were asking for a big commitment upfront with no way for the prospect to get a feel for the quality of the content. We advised them to pause the ads, and instead, we helped them build a funnel that clearly demonstrated value before asking for the sale. As I've done for other clients, sometimes it’s as simple as adding a demo video or a limited-time launch discount to remove that initial friction. Conversions shot up. It wasn't about changing the ad keywords; it was about changing the entire sales process. This is the difference between media buying and being a genuine growth partner.

What should I really look for in a UK Google Ads agency?

Okay, so you understand that it's about the whole funnel. Now, how do you find an agency that actually gets this? Here's what to screen for.

First and foremost, you need to see irrefutable proof that they've done this before. And I don't mean a vague testimonial on their website saying "They were great to work with!". I mean a detailed case study, ideally for an online course or an eLearning platform in a similar space to yours. They should be able to walk you through the entire campaign: what the objective was, what strategy they used, what the key metrics were, and what the final return on ad spend (ROAS) was. For one of our clients selling courses, we took them to $115k in revenue in just 1.5 months. For another, we hit a 447% ROAS in 1 week. And for an eLearning app, we drove over 45,000 signups at under £2 cost per signup using a multi-channel approach that included Google Ads. These are the kinds of concrete numbers you should be looking for. If an agency is cagey about sharing their results or just talks in terms of 'brand awareness' or 'click-through rate', they're hiding something. It usually means their campaigns don't actually make their clients any money.

Second, listen to the questions they ask you on the initial consultation call. A poor agency will ask about your budget and what keywords you want to target. A great agency will ask about your student. They'll want to know: Who is your ideal student? What is their biggest pain point? What transformation does your course provide? What's the lifetime value of a student? They'll dig into your business model because they know that's where the real levers for growth are. They're not just trying to sell you a service; they're trying to diagnose your business's growth problem. This is a critical distinction. To get a better idea of what to look for, you can check out this guide on how to find the right UK course creator ad experts, which goes into more detail.

Finally, they should be comfortable talking about more than just Google Ads. The best strategies are often multi-channel. For courses, a powerful approach is to use Google Search to capture people who are actively looking for a solution right now (e.g., searching for "learn python for data science course") and then use Meta (Facebook & Instagram) ads to retarget those website visitors, showing them student testimonials and success stories to build trust and persuade them to enrol. An agency that only knows one platform will try to solve every problem with that one tool. You want a partner who can look at the bigger picture and recommend the right channel for the right job. For many course creators, the blueprint for successful course sales is actually on Meta Ads, not just Google.

Can I even afford this? The crucial LTV calculation you must do

This is the question that stops most course creators in their tracks. They see the cost per click on Google and panic. "I can't afford to pay £5 every time someone clicks my ad!" But that's the wrong way to look at it. The only question that matters is: "How much can I afford to spend to acquire a new student and still make a healthy profit?"

The answer lies in a metric called Lifetime Value (LTV). This is the total amount of profit you can expect to make from a single student over the entire time they are with you. If you only sell one course for £500 and have no other products, your LTV is pretty straightforward. But what if you have an upsell to a more advanced course? Or a membership community? Or coaching services? Suddenly, that initial £500 student could be worth thousands over their lifetime.

Once you know your LTV, you can work backwards to figure out your maximum allowable Customer Acquisition Cost (CAC). A healthy ratio for a digital product business is often a 3:1 LTV to CAC. This means for every £1 you spend on ads to get a customer, you should be making £3 back in lifetime profit. So if your LTV is £3,000, you can afford to spend up to £1,000 to acquire that customer. Suddenly that £5 click doesn't seem so scary, does it?

Most agencies won't talk to you about this. They'll talk about Cost Per Lead (CPL) because it's an easier metric to influence. But a cheap lead who never buys is worthless. I'd rather pay £100 for a lead that I know converts into a £3,000 student than £1 for a lead that just clogs up my email list. To help you figure this out, I've built a simple calculator. Plug in your numbers and it'll give you a realistic idea of what you can afford to spend.

What does a winning ad strategy for a UK course actually look like?

A winning strategy is a ruthless focus on commercial intent. You need to find the people who aren't just curious about your topic, but are actively looking to pay for a solution. This is where Google Search ads shine, but only if you get the keywords right.

Forget targeting broad, informational keywords like "what is digital marketing". The volume is huge, but the intent is terrible. You'll get thousands of clicks from students doing research for an essay, not from professionals looking to upskill. Instead, a smart agency will focus on long-tail, high-intent keywords. Think phrases like:

• "best advanced excel course for finance professionals UK"
• "part-time coding bootcamp london"
• "certified project management course online"
• "learn public speaking for executives"

See the difference? These searches are dripping with intent. The user has a specific problem, they're looking for a specific type of solution, and they're often including commercial terms like "course", "certified", or "bootcamp". The competition for these keywords is higher, and the cost per click will be more expensive, but the quality of the traffic is infinitely better. One enrolment from a £10 click is better than zero enrolments from a hundred £0.50 clicks. A good agency will spend hours doing deep keyword research to uncover these golden nuggets for your specific niche. They'll also use compelling ad copy that speaks directly to the searcher's goal, which is why it helps to look at some high-converting ad copy examples from the London market.

But the strategy doesn't stop at Google. What about the people who clicked your ad, looked at your course page, but didn't buy? You can't just let them go. This is where a savvy agency will use retargeting ads on platforms like YouTube, Facebook, and Instagram to stay top of mind. They can show these warm prospects video testimonials from happy students, case studies of career transformations, or even a special time-limited discount to encourage them to take the leap. This multi-channel approach is how you turn clicks into a predictable system for enrolments.

What kind of results are actually realistic in the UK?

This is the million-dollar question, isn't it? Or rather, the million-pound question. The truth is, it varies massively depending on your niche, your price point, and the quality of your sales funnel. Anyone who gives you a fixed "cost per enrolment" without knowing these details is just guessing.

However, we can look at some benchmarks. Based on the campaigns we've run for course creators and eLearning platforms, we can get a rough idea. For a lower-ticket course (under £200), you might aim for a cost per purchase of £20-£50. For a mid-range course (£500-£1500), a cost of £100-£300 per enrolment could still be very profitable, especially if your LTV is high. For high-ticket coaching or mastermind programs (£2000+), it's not uncommon to pay £500 or more to acquire a single customer, because the return is so massive.

The key metric isn't the cost per sale, but the Return on Ad Spend (ROAS). If you spend £1 and make £4 back in course sales, that's a 4x or 400% ROAS. That's a healthy target for a well-optimised campaign in a competitive market. We've seen it go much higher - one of our subscription box clients hit a 1000% ROAS, but that's exceptional. A consistent 3x-5x ROAS is a brilliant, scalable result for most course businesses.

To give you a visual idea, here's a breakdown of typical cost-per-acquisition ranges you might see in the UK for different goals within a course sales funnel.

How do I avoid getting ripped off? Spotting the red flags.

The paid ads industry, especially in a competitive market like London or the wider UK, is unfortunately full of cowboys. They talk a good game but can't deliver the goods. Learning to spot the red flags is probably the most important skill you can have when hiring.

The biggest red flag of all is a guarantee of results. If anyone ever says to you "We guarantee you a 10x ROAS" or "We'll double your enrolments in 30 days, guaranteed", run for the hills. No one can ethically or honestly guarantee results in advertising. There are simply too many variables: market changes, competitor actions, platform algorithm updates, and your own sales process. An experienced professional will talk in terms of realistic targets, benchmarks, and a clear process for testing and optimisation. They'll promise to apply their proven process, not a magical outcome.

Another one is an obsession with vanity metrics. If their reports and conversations are all about impressions, clicks, and click-through rates (CTR), be very wary. These metrics are easy to manipulate. I can get you a million impressions and a thousand clicks tomorrow by targeting a broad, cheap audience in a developing country. Will any of them buy your course? Absolutely not. The only metrics that matter are the ones that affect your bank balance: Cost Per Enrolment, Return on Ad Spend, and Lifetime Value. If they're not focused on these, they're not focused on your growth.

Finally, a lack of transparency is a deal-breaker. You should always have full, administrative access to your own ad accounts. Some old-school agencies try to run campaigns through their own accounts, which means you can never leave them without losing all your data and campaign history. It's a dodgy tactic to lock you in. A trustworthy partner will build everything inside your accounts, making you the owner of your own data from day one. There is a lot to consider, and if you are based in the capital, it might be worth reading up on London's ultimate guide to hiring a paid ads expert to get a more local perspective.

The final test: What to ask on the consultation call

You've done your research, you've checked their case studies, and you've shortlisted two or three agencies that seem to tick the boxes. The final step is the consultation call. This is your chance to really grill them and see if they live up to the hype. Don't be afraid to ask tough questions. A good agency will welcome them; a bad one will get defensive.

Here are my go-to questions to separate the experts from the amateurs:

1. "Can you walk me through the strategy you'd propose for my course, based on what you know so far?" - This tests if they've done their homework. A great agency will have already looked at your website and your competitors and will have some initial ideas. They should be able to talk about keyword themes, potential audiences, and offer suggestions beyond just "we'll run some search ads."
2. "What does your onboarding process look like in the first 30 days?" - This reveals how organised they are. You're looking for a clear, structured plan that includes things like technical setup (pixel tracking, conversion goals), market research, strategy development, creative build-out, and a launch timeline. If they're vague, it probably means their process is chaotic.
3. "How do you handle reporting and communication?" - You want a partner, not a black box. They should have a clear cadence for communication (e.g., weekly updates, a monthly strategy call) and provide reports that focus on the business metrics that matter (spend, revenue, ROAS, CPA), not just a data dump of clicks and impressions.
4. "What's the biggest mistake you see course creators making with their ads, and how would you help me avoid it?" - This is a great question to test their real-world experience and strategic thinking. Their answer will tell you a lot about their philosophy and whether they truly understand the challenges of your specific business model.
5. "What happens if the campaigns aren't working after the first month?" - This is the most important question. A bad agency will make excuses. A good agency will have a clear process for diagnosing problems. They'll talk about analysing the data, forming new hypotheses, and systematically testing variables like ad creative, landing page copy, and audience targeting until they crack the code. Their answer should inspire confidence in their process, not their ability to get it right on the first try.

Finding the right agency is a lot of work, I know. It's a far cry from just picking the first one you find on Google. But the difference between the right partner and the wrong one isn't just a few percentage points on your ROAS. It's the difference between stagnating and scaling, between wasting your budget and building a predictable engine for student enrolments that can transform your business. You've already done the hard work of creating a brilliant course; it's worth putting in the effort now to find a partner who can help you get it in front of the people who need it most.

To help you put all of this into action, I've summarised the key takeaways in a simple table below.

Is it time to call in the experts?

Look, going through this process is a huge amount of work. It requires expertise not just in Google Ads, but in copywriting, conversion rate optimisation, business strategy, and data analysis. If you're a course creator, your time is best spent on creating amazing content and engaging with your students, not trying to become a world-class digital marketer overnight.

This is where hiring a true growth partner can be one of the best investments you ever make. A great agency doesn't just save you time; they bring years of experience from running hundreds of campaigns and spending millions of pounds. They've already made all the expensive mistakes, so you don't have to. They can compress years of learning into months of results, helping you scale faster and more profitably than you ever could on your own.
