B2B Google Ads in the UK: The Only Guide You Need

Running Google Ads for B2B in the UK feels like throwing money into a black hole for most founders. You're told to target "decision-makers" at "companies with 50-200 employees" in the "finance sector," and you end up with a huge bill and a handful of leads from interns at companies that can't afford you. The entire approach is fundamentally broken. You are not targeting a demographic; you should be targeting a state of professional crisis.

The secret isn't a more complex campaign structure or a secret bidding strategy. It's about a ruthless focus on three things: the customer's specific nightmare, the maths behind what they're actually worth to you, and an offer so good it makes a demo request feel like a natural next step, not a chore. Forget everything you've been told about broad targeting and awareness. We're going to focus on how to attract high-value UK clients who are actively looking for the very expensive problem you solve.

What if my Ideal Customer Profile isn't a person?

Your last marketing hire probably gave you a PowerPoint slide defining your Ideal Customer Profile (ICP) as "Sarah, a 45-year-old Head of Engineering at a FinTech in Canary Wharf." This is utterly useless. It leads to generic ad copy and targeting that speaks to no one. You need to stop thinking about who your customer *is* and start obsessing over the problem that keeps them awake at night.

Your ICP is a nightmare. It’s a specific, urgent, expensive, and potentially career-threatening problem. For that Head of Engineering, the nightmare isn't 'needing better project management'; it's 'her best three developers are about to quit because the workflow is a chaotic mess, derailing a critical product launch.' For a legal tech SaaS, the nightmare isn't 'inefficient document storage'; it's 'a senior partner missing a filing deadline due to a lost document, exposing the firm to a multi-million-pound malpractice suit.'

Once you've defined this nightmare, your targeting becomes laser-focused. Where does this person go to solve their pain? They aren't browsing Facebook. They're probably listening to specific tech podcasts like 'Acquired' on their commute from Surrey, reading industry newsletters like 'Stratechery', or asking for recommendations in private Slack communities. Your job is to find the digital watering holes where these professionals gather. This intelligence is the foundation of your entire strategy. If you haven't done this work, you have no business spending a single pound on ads.

How do I find keywords that actually generate UK leads?

Most B2B Google Ads accounts I audit are burning cash on broad, informational keywords. Bidding on something like "cybersecurity" is a donation to Google. You're competing with universities, news sites, and giants with million-pound budgets. You need to focus exclusively on keywords that signal commercial or transactional intent.

Think of it like a funnel. A person in pain will search differently at each stage. Your job is to intercept them at the bottom, right before they make a decision. This isn't just about theory; getting this right is the difference between a profitable campaign and a failed one. For a deeper look into this, we have a complete guide on structuring B2B SaaS campaigns in the UK that builds on this principle.

Your keyword list should be small and aggressive. Instead of 1,000 broad match keywords, you want 50 exact match keywords that scream "I have a problem and I need to pay someone to fix it now." For instance, in one B2B campaign we ran for a client in environmental controls, we managed to reduce their cost per lead by 84% simply by cutting this kind of fat and focusing only on high-intent prospects. This shift in focus is non-negotiable.

How much can I actually afford to pay for a UK lead?

This is the most important question, and almost nobody does the maths. The question isn't "How low can my Cost Per Lead (CPL) go?" but "How high a CPL can I afford to acquire a fantastic customer?" The answer is found by calculating your Customer Lifetime Value (LTV).

Without knowing your LTV, you're flying blind. You might pause a campaign with a £250 CPL, thinking it's too expensive, when in reality that lead turns into a £15,000 client. You're making decisions based on fear, not data. I remember one client with a medical job matching SaaS platform who came to us with a £100 Cost Per Acquisition. By helping them understand their numbers and optimising their entire funnel, not just the ads, we brought that down to just £7. This kind of transformation starts with knowing your LTV.

Here’s the basic formula:

Let's run through a quick example. A UK SaaS business charges £500/month (ARPA), has an 80% gross margin, and loses 4% of its customers each month (churn).
LTV = (£500 * 0.80) / 0.04 = £400 / 0.04 = £10,000.

Each customer is worth £10,000. A healthy LTV to Customer Acquisition Cost (CAC) ratio is 3:1, meaning you can afford to spend up to £3,333 to acquire a customer. If your sales team converts 1 in 10 qualified leads, you can pay up to £333 per lead. Suddenly that £250 lead doesn't look so bad. Use the calculator below to find your own number.

Why is my ad copy being ignored?

Your ad copy is probably focused on you: your features, your company, your awards. Your potential customer doesn't care. They care about their problem. Your ad's only job is to enter the conversation already happening in their head.

To do this, use a proven copywriting framework. For a high-touch UK service business, deploy Problem-Agitate-Solve. You don’t sell "fractional CFO services"; you sell a good night's sleep to a stressed founder in Shoreditch.

• Problem: Are your cash flow projections just a guess?
• Agitate: Worried one bad month could mean missing payroll while competitors are raising their next round?
• Solve: Expert financial strategy for a fraction of a full-time hire. Turn uncertainty into predictable growth.

For a B2B SaaS product, use the Before-After-Bridge. You don’t sell a "FinOps platform"; you sell the relief of a predictable cloud bill.

• Before: Your AWS bill just landed. It’s 30% higher than last month, and your engineers have no idea why. Another fire to put out.
- After: Imagine opening your cloud bill and smiling, seeing exactly where every pound is going and waste is automatically cut.
• Bridge: Our platform is the bridge that gets you there. Start a free trial and find your first £1,000 in savings today.

Notice how both examples focus entirely on the customer's pain and desired outcome. Your product is just the vehicle. This is how you stop the scroll and earn the click. Your ad copy needs to be less about what you do, and more about what you do *for them*. A small change in perspective here can make a massive differance.

Is my Call to Action killing my campaign?

Absolutely. The "Request a Demo" button is the most arrogant, high-friction Call to Action in B2B marketing. It presumes your prospect, a busy UK director, has nothing better to do than schedule a meeting to be sold to. It screams "I want your time before I've provided any value." It's a conversion killer and instantly positions you as a commodity.

Your offer's only job is to deliver an "aha!" moment of undeniable value that makes the prospect sell themselves on your solution. You must solve a small, real problem for free to earn the right to solve their bigger problems for a fee. The goal is to make them think, "If their free stuff is this good, what must the paid version be like?"

Here are some offers that actually work:

• For SaaS: A free trial with no credit card required. Let the product do the selling. This creates Product Qualified Leads (PQLs) who are already convinced, not Marketing Qualified Leads (MQLs) your sales team has to chase.
• For Agencies/Consultancies: A free, automated tool. A marketing agency could offer a free SEO audit that reveals a prospect's top 3 keyword opportunities. For us, it's a 20-minute strategy session where we audit failing ad campaigns. It's a taster of our expertise.
• For Complex Services: A valuable asset. A data analytics firm could offer a free 'Data Health Check' that flags critical issues in their database. A corporate training company could provide a free 15-minute interactive video module on 'Handling Difficult Conversations'.

Switching from a high-friction ask to a high-value give is probably the single biggest lever you can pull to improve your campaign performance. This is central to a successful B2B lead generation strategy in the UK, where decision-makers are time-poor and skeptical.

How should I actually structure my UK B2B campaigns?

Complexity is the enemy of performance. You don't need dozens of campaigns and ad groups. You need a simple structure based on intent. For most UK B2B businesses, this is all you need to start:

1. One Search Campaign - High-Intent Keywords: This is your workhorse. It contains a small number of ad groups, each focused on a tight theme of transactional keywords (e.g., "b2b crm software," "salesforce consultant london"). Use Exact and Phrase match only. This is where you'll get your most qualified leads.
2. One Performance Max Campaign - Broader Reach (Optional): Once your Search campaign is working, you can test PMax. But be careful. You need to feed it strong audience signals based on your best converting customers and website visitors. Without this guidance, PMax can easily waste your budget on irrelevant traffic. If you're new to this campaign type, our guide on mastering Performance Max for B2B is a good starting point.
3. One Branded Search Campaign: A simple campaign with one ad group bidding on your company name and variations. This is non-negotiable. It protects you from competitors bidding on your name and captures the highest-intent traffic of all.

For location targeting, be specific. If your clients are concentrated in London's financial district, target postcodes in and around the City of London and Canary Wharf. If you serve manufacturing firms in the Midlands, target Birmingham, Coventry, and surrounding industrial areas. Don't just blanket-target the whole UK unless you truly serve everyone, everywhere. Granularity here reduces waste and improves relevance.

My landing page gets clicks but no conversions, what's wrong?

Driving traffic is only half the battle. If your landing page isn't built to convert, you're just paying to show people your logo. The page has one job: to convert a visitor into a lead by delivering on the promise of your ad. A disconnect between your ad message and your landing page is a common reason for failure. Many businesses get good traffic that simply doesn't convert, which requires a deep look into ad and landing page alignment.

Your page must have:

• Message Match: The headline must echo the ad copy. If the ad promises a "Free SEO Audit," the headline must say "Get Your Free SEO Audit."
• Social Proof: Logos of well-known UK clients, testimonials with names and photos, case study results in Pounds (£). This builds trust.
• Clarity Over Clutter: Remove all distractions. No navigation bar, no footer links to your blog. Just one clear path to the conversion action.
• A Single, Clear Call to Action: The button should clearly state the value exchange. Not "Submit," but "Get My Free Audit" or "Start My Free Trial."
