Solved: Finding a Paid Ad Agency to Improve ROI

Hi there,

Thanks for reaching out! It’s a really common problem you're facing. The market is absolutley flooded with agencies all claiming to be the best, and it's almost impossible to tell who actually knows their stuff and who's just good at selling themselves. It can feel like a total minefield.

I'm happy to give you some initial thoughts and guidance based on my experience. This isn't a sales pitch, just some honest advice from someone who's been in the trenches with paid ads for years. Hopefully it'll help you figure out what to look for and what questions to ask when you're talking to potential partners. Finding the right fit is less about their promises and more about their process and how they think.

We'll need to look at what really drives results... and it isn't the ads themselves

Here’s the first big truth that most agencies won't tell you, because it's not what you want to hear. The number one reason paid advertising campaigns fail has almost nothing to do with the ads themselves. It's the offer. If your offer isn't hitting the mark for a specific audience with a genuine need, you can have the best-looking ads in the world and you'll just be burning cash faster.

I see it all the time. Founders who are passionate about their product, they've spent ages developing it, adding features, making it perfect. But they've built it without a crystal-clear picture of who it's for and what urgent, expensive problem it solves for them. So when they come to advertise, they struggle to get any traction because there's a basic lack of demand for what they're selling, at least in the way they're presenting it.

A good agency, a really good one, will challenge you on this before they even talk about platforms or budgets. They'll want to dig deep into your Ideal Customer Profile (ICP). And I don't mean the generic stuff like "companies in the finance sector with 50-200 employees." That's useless. It tells you nothing and leads to bland ads that nobody cares about.

You have to define your customer by their nightmare. What is the specific, career-threatening, keeps-them-up-at-night problem they are dealing with? Your client isn’t just a job title. They're a person terrified of something. I remember one software company we worked with, their Head of Engineering wasn't just "looking for efficiency tools"; he was terrified his best developers would quit because their workflow was a mess. That's the pain. That's the nightmare. An agency that doesn't push you to define this is just planning to take your money and press 'go' on some generic campaigns.

Once you know that nightmare, a good partner helps you figure out where that person lives online. What podcasts do they listen to? What industry newsletters do they actually read? What software tools do they already use and pay for? This isn't just data, it's the entire blueprint for your targeting. If an agency jumps straight to "we'll target these keywords" without doing this foundational work, they're missing the most important part of the puzzle.

I'd say you need to understand the numbers that actually matter

Before spending a single pound on ads, you have to know if it's even possible to be profitable. The question isn't "how cheap can I get my leads?" but "how much can I afford to pay for a great customer?" This is all about Customer Lifetime Value (LTV). Any agency worth their salt should be having this conversation with you on the first call. If they don't, it's a massive red flag.

The calculation is pretty straightforward but so many businesses never do it. It looks something like this:

So in this example, every new customer is worth £10,000 in gross margin to you. Now we know what we can afford to spend. A healthy LTV to Customer Acquisition Cost (CAC) ratio is about 3:1. This means you can afford to spend up to £3,333 to get a new customer. If your sales process converts 1 in 10 qualified leads, you can afford to pay up to £333 for a single lead.

Suddenly that £50 lead from Google or that £200 lead from LinkedIn doesn't seem so expensive, does it? It looks like a bargain. This is the maths that allows you to grow aggressively and intelligently. An agency that just focuses on getting you a low Cost Per Lead (CPL) without this context is doing you a disservice. They might be getting you lots of cheap, rubbish leads that never convert, while a more expensive lead from the right person could be incredibly profitable.

This also helps set realistic expectations for costs. People often ask what they should expect to pay for a conversion. Honestly, it varies massively. But here’s a rough idea based on what we see across thousands of campaigns.

These are just ballpark figures, of course. For B2B, leads can be much more expensive. For one B2B SaaS client, we consistently get leads from decision makers on LinkedIn for around $22, which is fantastic value for them given their LTV. For another B2B software client on Meta, we achieved a registration cost of $2.38 for over 4,600 registrations. It all depends on the niche, the offer, and the targeting. But an agency should be able to have this kind of conversation with you and set realistic expectations from the get go.

You probably should choose the right channel and objective

Once the foundations are solid, then you can talk about channels. An agency should be able to clearly articulate why they're recommending a certain platform. It's not a one-size-fits-all solution.

The first question is: are your ideal customers actively searching for a solution to their problem right now?

-> If yes, Google Search ads are almost always the best place to start. You're capturing intent. Someone is literally typing "emergency electrician near me" or "best accounting software for small business" into a search bar. They have a problem and they want it solved now. This is the lowest hanging fruit. A good agency will do thorough keyword research to find the phrases that signal buying intent, not just informational queries.

-> If no, then you need to go out and find them on social media. This is interruption marketing. You need to get their attention. For B2B, LinkedIn is usually the top choice because the targeting is so specific. You can target by job title, company size, industry, etc. For many of our B2B clients, it's the primary channel. However, Meta (Facebook/Instagram) can also work surprisingly well for B2B if your audience is there. We've had great sucess finding small business owners or targeting people with interests in specific software like Shopify or Salesforce. I recall one client, a medical job matching SaaS, where we reduced their Cost Per User Acquisition from £100 down to just £7 using a mix of Meta and Google Ads.

Then there's the campaign objective. This is a simple thing that so many get wrong. If you tell Facebook you want "Brand Awareness" or "Reach," it will do exactly what you ask: it will show your ad to the largest number of people for the cheapest price. And who are those people? The ones who never click, never engage, and never buy anything. Their attention is cheap for a reason. You're literally paying to find the worst possible audience. A competent agency knows this and will almost always optimise for a conversion objective - a lead, a sale, an appointment booking. Awareness is a byproduct of getting actual customers, not a goal in itself for most businesses.

You'll need a message and an offer they can't ignore

This brings us back to the creative and the offer. A good agency doesn't just manage your ads; they help you craft a message that resonates deeply with that "nightmare" problem we talked about earlier. They should be using frameworks like Problem-Agitate-Solve.

You don't sell "fractional CFO services." You sell "a good night's sleep." The ad should sound like: "Are your cash flow projections just a wild guess? Are you one bad month away from a payroll crisis? Get an expert financial strategy for a fraction of a full-time hire." You see the difference? It's all about the pain.

And then there's the Call to Action (CTA). The "Request a Demo" button is probably the worst CTA ever invented. It’s high-friction and low-value. It screams "I am about to sell to you for an hour." A good agency will push you to create a better offer, one that provides immediate value for free. This is how you earn the right to have a sales conversation.

For a SaaS company, it's a free trial with no credit card. Let them use the product and see the value for themselves. For a service business, it could be a free automated audit, a checklist, a short video course, or a strategy session. For our agency, for example, we offer a free 20-minute strategy session where we audit a company's existing ad campaigns. We solve a small problem for free to show we can solve the whole thing. An agency that just defaults to "Request a Demo" is lazy and following an outdated playbook.

So, how do you actually choose the right partner?

Okay, so after all that, we're back to your original question. Now that you know what 'good' looks like, here's a practical process for vetting agencies:

1. Scrutinise their Case Studies: Don't just look at the shiny logos. Do they have experience in a niche similar to yours? Do the results they talk about seem realistic and relevant? For instance, when we talk to a SaaS company, we can point to specific campaigns like one where we generated 5,082 software trials at $7 each on Meta Ads, or another where we drove 1,535 trials for a B2B SaaS, also on Meta Ads. This shows we've been there and done that. If an agency's case studies are all vague or in completely unrelated industries, be wary.

2. Get on a Call and Listen: Book that initial consultation. A good agency will use this time to ask you lots of questions. They'll want to understand your business, your customers, your numbers, your 'nightmare' ICP. If they spend the whole time talking about themselves and their amazing process without understanding your context, it's a bad sign. You're looking for someone who demonstrates expertise by the quality of their questions, not the slickness of their presentation.

3. Look for Expertise, Not Promises: This is absolutley critical. In paid advertising, nobody can promise results. There are too many variables. If an agency guarantees you a specific ROAS or a certain number of leads, they are either lying or inexperienced. What they can do is show you a proven process for testing, learning, and optimising towards your goals. Look for a partner, not a magician.

4. Check Their Reviews: What are actual past clients saying about them? Look for detailed reviews that talk about the working relationship, the communication, and the process, not just the final results.

To be honest, if an agency has solid, detailed case studies, gives you a genuinely valuable free consultation, and has great reviews, that's about as much certainty as you can get. If after all that, a prospect asks us for references to call one of our other clients, it's usually a red flag for us. It signals a fundamental lack of trust that probably won't get better over time, and we'd likely decide we're not a good fit.

I've detailed my main recommendations for you to take away below:

This is a lot to take in, I know. But doing this homework up front will save you a huge amount of time, money, and frustration down the line. It's the difference between finding a true growth partner and just hiring another vendor who underdelivers.

The reality is that this process of deep analysis, strategic planning, constant testing, and optimisation is a full-time job. That's where an expert consultancy can make a huge difference. We can bring years of experience from hundreds of campaigns to your business, helping you avoid common pitfalls and scale faster and more profitably than you could on your own.

If you'd like to have a more specific chat about your business, we offer a completely free, no-obligation 20-minute strategy session where we can look at your situation in more detail and give you some concrete, actionable advice. It could be a really good way for you to pressure-test some of these ideas and see what it's like to work with a team that focuses on these fundamentals.

Hope this helps give you a clearer path forward!
