The Founder's Playbook: Using Paid Ads to Validate Your Offer

Stop building. Seriously. Before you write another line of code, design another feature, or perfect another slide in your pitch deck, you need to answer one question. Does anyone actually want this thing? Not your mum, not your mates down the pub, but a real, breathing stranger who is willing to part with their cash or their valuable time for it. Too many founders burn through their savings and their sanity building a solution to a problem that doesn't exist. They follow the "build it and they will come" fairytale, only to launch to the sound of crickets.

There's a better way. A faster, cheaper, and brutally honest way to find out if you've got a winner or a dud. It’s called paid advertising. But not in the way you think. We're not talking about scaling to the moon here. We're talking about using platforms like Meta and Google as a truth machine. A way to get your offer in front of real people and see if they vote with their clicks and their details. This isn't a guide to getting a million users overnight. This is a playbook for using a small, controlled ad budget to validate your core business idea, before you bet the farm on it. It’s about replacing guesswork with data and hope with hard evidence. If you follow this, you'll either find the proof you need to go all-in with confidence, or you'll get the cheap, fast 'no' that saves you from years of wasted effort. So lets get into it.

So, why do most founders get this so wrong?

The number one reason businesses fail isn't a lack of funding or a bad team. It's a lack of customers. And a lack of customers comes from a lack of demand for what you're selling. It sounds simple, but it's the rock that sinks so many startups. Founders fall in love with their idea. They see a cool piece of technology, or have a "vision" for a product, and they spend months, sometimes years, perfecting it in a vacuum. They build feature after feature, polish the user interface, and get everything 'just right'.

The problem is, they never stopped to ask if anyone was desperately searching for that solution in the first place. They build a brilliant key for a lock that doesn’t exist. This is the fundamental reason so many paid ad campaigns are doomed from the start. You can have the most sophisticated targeting and the most beautiful ad creative in the world, but if you point it at an offer nobody wants, you're just paying to prove your own idea is a bad one. The ad campaign doesn't fail; it just exposes the lack of demand that was already there.

Validation isn't sending a survey to your friends. They'll be nice to you. It's not getting positive feedback in a focus group. People will tell you what they think you want to hear. Real validation is a transaction. It's a stranger, who owes you nothing, seeing your offer and taking a tangible action. They give you their email for a waitlist. They sign up for a free trial. They pull out their credit card. That's the only feedback that matters, and it's the feedback we're going to get with a small, strategic ad spend.

What does a 'validated' offer actually look like?

Before we even think about ads, we need to be crystal clear on what we're testing. A validated offer isn't just a product. It's a solution to a very specific, very painful problem for a very specific group of people. If you can't articulate this clearly, you have no business spending money on ads. The biggest mistake is trying to be everything to everyone. Your offer becomes generic, your message becomes diluted, and it resonates with absolutely no one.

This is where most founders go wrong with their Ideal Customer Profile (ICP). They create a sterile, demographic-based description like "SMEs in the tech industry with 50-100 employees". That tells you nothing. It's useless. It leads to boring, generic ads that get ignored. You need to stop thinking about demographics and start thinking about nightmares.

What is the specific, urgent, expensive, career-threatening problem that keeps your ideal customer awake at night? That's your real ICP. It's not a person; it's a problem state.

-> For a legal tech SaaS, the nightmare isn't just 'needing better document management'. It's the partner who wakes up in a cold sweat terrified that a junior associate missed a critical filing deadline, exposing the entire firm to a multi-million-pound malpractice lawsuit.

-> For a fractional CFO service, the nightmare isn't 'wanting financial reports'. It's the founder who is staring at their bank balance, having no real idea if they can make payroll next month, while their main competitor just announced a massive new funding round.

Once you've isolated that nightmare, you can build your entire strategy around it. Your ad copy, your landing page, your offer – everything should speak directly to that pain. This is how you cut through the noise. You’re not just another vendor; you’re the aspirin for their splitting headache. Getting this right is the absolute foundation, and if you're struggling with it, you need to look at our guide on escaping targeting nightmares, because a poorly defined audience will kill your campaign before it even starts.

How do you craft an offer they can't possibly ignore?

Now that you understand your customer's nightmare, you can craft a message that they simply can't ignore. This isn't about listing features. Nobody cares about your features. They care about what those features do for them. They care about getting rid of their pain. We use a few simple but powerful copywriting frameworks to do this.

For a service business, you use Problem-Agitate-Solve (PAS). You don't sell 'custom software development'; you sell a way to finally crush that legacy system that’s killing productivity.

-> Problem: "Is your dev team spending more time patching your ancient legacy software than building new features?"
-> Agitate: "Every day they're fighting fires is a day your competitors are pulling further ahead. Top talent is walking out the door out of sheer frustration."
-> Solve: "We replace your legacy headache with a custom-built, scalable platform in 90 days. Get back to innovating, not maintaining."

For a B2B SaaS product, you use Before-After-Bridge. You don't sell a 'project management tool'; you sell the feeling of calm control.

-> Before: "Your projects are chaos. Deadlines are missed, communication is scattered across emails and Slack, and nobody knows who's doing what."
-> After: "Imagine a single dashboard where every project is on track, every conversation is organised, and you have complete clarity on your team's progress."
-> Bridge: "Our platform is the bridge that takes you from chaos to control. Sign up for a free trial and get your first project organised in 10 minutes."

Notice how specific and tangible these are. They're not vague promises. They paint a picture. This kind of powerful messaging is what makes for irresistible ad creative. If your ads are getting ignored, it's probably because your message is too generic and feature-focused. You're talking about yourself, not about them and their problems. One of the most powerful things you can do, especially for a service, is to productise it. Give it a name, a clear process, and a defined outcome. I remember one client who was a videographer. They didn't just sell "brand films." They sold a "1-Day Filming Process" that delivered a package of 1 hero video and 10 social media clips. It made the intangible tangible, and much easier for a client to buy.

Your Validation Machine: The Minimum Viable Funnel

You don't need a 20-page website with a blog and an 'About Us' section to validate your offer. In fact, that stuff just gets in the way. You need a simple, focused, one-page machine designed to do one thing and one thing only: get a conversion.

This is your Minimum Viable Funnel (MVF), and it has two parts: a landing page and an offer.

1. The Landing Page: Your Digital Sales Pitch

This is a single webpage with a single goal. There are no navigation links to distract people. No links to your social media. Just a focused, persuasive argument for why they should take the one action you want them to take. It should load fast and be ruthlessy simple.

Your landing page must have:

-> A Killer Headline: This should state the 'After' state from the Before-After-Bridge. The big promise. "The Accounting Software That Saves You 10 Hours a Week."
-> The Pain: Use the PAS framework. Remind them of the nightmare you're solving.
-> The Solution: Briefly explain how your offer makes the pain go away. Focus on benefits, not features.
-> A Single, Clear Call-to-Action (CTA): One button. One action. No confusion.

Building one of these isn't rocket science, but there are a lot of small details that can make or break your conversion rate. If you want to go deeper, we've written the ultimate guide to high-converting landing pages that covers everything you need to know.

2. The Offer: Delete the "Request a Demo" Button

This is the most critical part, and where so many B2B founders fall flat on their face. The "Request a Demo" button is possibly the worst call to action ever invented. It's high-friction and screams "I am going to sell to you for an hour". It presumes your prospect, a busy decision-maker, has nothing better to do than schedule a sales pitch. It's an instant turn-off.

Your offer's only job is to provide a moment of instant value. An "aha!" moment that makes the prospect sell themselves. For validation, your offer must be as low-friction as possible.

Here are some great alternatives:

-> For SaaS: The gold standard is a free trial or a freemium plan, with no credit card required. Let them actually use the product and experience the value. This is how you generate Product Qualified Leads (PQLs) who are already half-sold. It's the core of our paid acquisition guide for SaaS founders.
-> For Pre-Launch/MVP: A waitlist. But not just a boring "join our newsletter" form. Make it exclusive. "Join the waitlist for 50% off your first 3 months." "Get early access before we launch to the public." This builds anticipation and lets you gauge demand before you've even finished building.
-> For Services/Consulting: Bottle your expertise into a free tool or asset. A free, automated website audit. A free 15-minute video training on a specific problem. For our agency, we offer a free 20-minute strategy session where we audit failing ad campaigns. We solve a small problem for free to earn the right to solve the big one. You must give value before you ask for a sale.

Choosing Your Truth Machine: Which Ad Platform?

Now that you have your ICP's nightmare, your irresistible offer, and your simple funnel, it's time to put it in front of people. The platform you choose depends entirely on where your customer lives and how they think about their problem.

Google Ads: Capturing Active Searchers

If your customer knows they have a problem and is actively searching for a solution, Google Search is your best bet. You're not creating demand; you're capturing it. This is for people typing things like "emergency electrician near me," "best crm for small business," or "accountant for startups."

The key here is intent. You want to bid on keywords that show someone is looking to buy, not just learn. "Software for lead generation" is a buying keyword. "What is lead generation" is a research keyword. Target the former. This is the fastest way to get in front of people who are already problem-aware and solution-aware. We've used this for service businesses to get leads for as low as £5 and for B2B SaaS to get signups by targeting keywords their competitors' customers might search for. The leads are often better qualified because they have pre-qualified themselves with their search.

Meta (Facebook & Instagram): Creating Demand

What if your customer doesn't know your solution exists, or maybe doesn't even realise the full extent of their own problem? This is where Meta comes in. You can't target them based on what they're searching for, so you target them based on who they are and what they're interested in.

For B2B, you can target people with interests like "small business owners" or who follow pages of industry software like Shopify or Salesforce. For B2C, you can target people who like specific brands, magazines, or hobbies related to your product. For one of our eCommerce clients selling women's apparel, we achieved a 691% return by targeting interests related to competitor brands and relevant fashion publications.

A crucial warning here: when you set up your campaign, you MUST optimise for conversions (leads, purchases, signups). Do not use "Reach" or "Brand Awareness." If you do, you are literally telling Facebook's algorithm to find the cheapest people to show your ad to, who are by definition the least likely to ever click or buy. It's the fastest way to burn your budget. You are paying to find non-customers. Awareness is a byproduct of making sales, not the other way around.

LinkedIn Ads: The B2B Sniper Rifle

If you need to get your offer in front of a specific Head of Marketing at a FTSE 250 company in the financial services sector, LinkedIn is your platform. The targeting is unparalleled for B2B. You can target by job title, seniority, company size, industry, specific company names, and more. It's more expensive, for sure, but the quality of the lead can be incredible because you know you're reaching the exact decision-maker.

We ran a campaign for a B2B software targeting decision-makers on LinkedIn and were getting highly qualified leads for just $22 CPL. That sounds expensive until you realise their customer lifetime value was over £10,000. It's a no-brainer. The key with LinkedIn is to have a very specific, high-value offer. Because it's a professional network, a hard sell often fails. An offer of a free whitepaper, an industry report, or an exclusive webinar works much better to start the conversation. It can feel like a lot to get your head around, which is why we put together a guide to help founders deal with the feeling of B2B advertising overwhelm.

Running the Test: What Does a "Win" Look Like?

Okay, you're ready to go live. How much should you spend, and what numbers actually matter?

Your Budget: Think Small

You don't need thousands of pounds for this. The goal is to get just enough data to make a decision. I'd recommend starting with a budget of £300-£500. Run it for about 7-10 days. This is enough to get a feel for the numbers without risking a significant amount of cash. The aim is to get a statistically significant number of clicks (maybe 100-200) to your landing page to see how it performs. If no one converts out of 200 visitors, your offer is probably a dud.

Metrics That Matter (and Those That Don't)

When your data starts coming in, it's easy to get distracted by vanity metrics. For validation, you need to be laser-focused on the numbers that signal real market interest.

-> IGNORE THESE (for now): Impressions, Reach, Click-Through Rate (CTR). Who cares how many people saw your ad if none of them converted? CTR is a bit more useful as it tells you if your ad creative is resonating, but it's secondary to the main goal.

-> FOCUS ON THESE:
1. Cost Per Lead/Acquisition (CPL/CPA): This is your most important number. How much does it cost you to get one person to sign up for your waitlist, trial, or free tool? This is the market's price for your offer.
2. Conversion Rate (CVR): Of the people who landed on your page, what percentage actually converted? A good landing page for a cold audience might see a 2-5% CVR. For a really strong offer, it could be 10%+. If it's below 1%, something is seriously wrong with your offer or your page.

Interpreting the Data: What is the Machine Telling You?

After a week, you'll have some data. This is where the real work begins. Your ad campaign isn't just a success or a failure; it's a diagnostic tool.

-> High clicks, but zero conversions? Congrats, your ad creative is great! People are interested in the promise you made. The problem is on your landing page or with the offer itself. They clicked expecting one thing and found something else, or the friction to sign up was too high. This is a common problem, we see it even on platforms like TikTok where you can get lots of clicks but no conversions if the landing page doesn't deliver.

-> Low clicks and a high Cost Per Click (CPC)? Your ad creative or your targeting is the problem. Your message isn't resonating with the audience you've chosen, or you've chosen the wrong audience entirely. The market is telling you "we don't care about this." Time to go back to your ICP nightmare and rewrite your ads.

-> A decent CPL/CPA? This is your green light! Let's say you're getting waitlist signups for £5 each. Now the question is, can you build a business on that? This is where knowing your numbers, like potential Lifetime Value (LTV), becomes critical. If you can acquire customers for £5 and they'll be worth £200 to you over time, you have a validated, scalable business model. Often, founders are overwhelmed by ad spend because they haven't done this math.

Here’s a simple diagnostic table:

The Pivot or Persevere Decision

After your test, you have data. Not opinions, not hope, but cold, hard data. Now you have to make a decision. There are three possible outcomes.

1. Green Light: Persevere & Optimise

You're getting conversions at a cost that makes sense. You have proven demand. The market has voted 'yes'. Now your job shifts from validation to optimisation. How can you lower that CPA? Can you improve the landing page CVR from 3% to 5%? Can you test new ad creatives to beat your winner? This is when you can start to slowly increase the budget and build a predictable growth engine. You've earned the right to scale. This is also where you might start to look at a more comprehensive paid ads strategy for the UK market to really ramp things up.

2. Yellow Light: Pivot & Retest

This is the most common outcome. You got some interest—a few signups, some clicks—but the numbers don't work. Your CPA is £50, but you need it to be £10. The data is not a failure; it's a guide. It's telling you what's broken. Go back to the diagnostic table. Is it the audience? The message? The offer? Make a single, significant change based on your hypothesis (don't change everything at once) and run the test again with another small budget. This iterative process of testing and pivoting is how you find product-market fit.

3. Red Light: Kill It & Move On

You spent £500, sent 300 people to your page, and got zero conversions. Or maybe one, from your cousin. The market has spoken, and it has said a resounding "no." This might feel like a failure, but it's actually your biggest success. You just saved yourself months or years of your life and tens of thousands of pounds building something nobody wanted. You discovered the truth for the cost of a weekend away. Be grateful for the cheap lesson, shelve the idea, and move on to the next one, armed with a powerful new playbook for validation.

This entire process can feel like a maze, and if your campaign isn't working, it can be tough to figure out why. We created an ultimate troubleshooting guide for failing ad campaigns to help you diagnose the exact problem.

Your Validation Playbook: A Summary

This is the main advice I have for you. It's a system for replacing guesswork with data. Follow it, and you'll know more about your business's viability in two weeks than most founders learn in two years.

When an Expert Eye Can Save You a Fortune

You can absolutly follow this playbook yourself. It's a powerful framework for de-risking your startup. But interpreting the signals the market sends back can be tricky, especially when you're so close to your own project. It's easy to misdiagnose the problem or get stuck in a cycle of testing the wrong things.

Sometimes, the difference between a £50 CPA and a £5 CPA isn't a massive strategic shift, but a few subtle tweaks to the audience, the ad copy, or the landing page that only an experienced eye can spot. An expert has seen hundreds of campaigns succeed and fail. They recognise the patterns instantly. They can look at your data and tell you with confidence whether the problem is your audience, your offer, or your messaging.

Deciding between hiring an agency or building your own team is a big decision for any founder. But when you're in the validation stage, a short, focused engagement with a consultant can be the most capital-efficient way to get the answers you need. It can prevent you from wasting thousands on a flawed test and get you to a 'yes' or 'no' from the market much, much faster.

If you're staring at your ad results and aren't sure what they mean, or you're about to launch a validation test and want to make sure it's set up for success, we offer a completely free, no-obligation strategy session. We'll look at what you've got and give you our honest, straightforward advice on what to do next. It might be the most valuable 20 minutes you spend on your business this year.
