Solved: High Google Ads cost per lead, low conversion rate

Hi there,

Thanks for reaching out and sharing what's going on with your Google Ads campaigns. I'm happy to give you some initial thoughts and guidance based on what you've told me and the kind of results I've seen with other B2B SaaS clients.

Pulling your hair out at $300 for a qualified lead that only converts at 3% to customer? Yeah, that sounds absolutely brutal, tbh. Doing the quick maths, that's a cost of about $10,000 per customer acquisition ($300 / 0.03), which is frankly way higher than where you'd want it to be for most B2B SaaS products to be remotely profitable, especially if your customer lifetime value isn't incredibly high.

You're right to be concerned. Seeing competitors make it work while you're burning through budget is frustrating as hell. It definitely points to something not quite right in the setup or strategy.

My immediate gut feeling, looking at those numbers, aligns with what I touched on briefly before – the issue is likely less about Google Search Ads *not* being the right platform (because as you say, your competitors are using it, and for B2B SaaS where people actively search for solutions, it often *is* the best place to start), and more about what's happening *after* someone clicks your ad.

Your website conversion rate needs attention...

This is where I'd focus first. You can have the best targeting in the world and the most compelling ad copy, but if the page people land on doesn't convince them to take the next step, you're just paying for clicks that go nowhere. $300 CPL suggests you need an awful lot of clicks to get that 'qualified' lead, which strongly indicates a low conversion rate on your site.

Think about your ideal customer, that small business owner or decision maker searching for a solution like yours. They click your ad because it sounded relevant. What do they see and experience when they hit your landing page?

Is it immediately clear what your software does and how it solves their specific problem? Is the value proposition compelling? I've looked at a lot of B2B SaaS sites where the homepage is just too generic, or it's not designed to guide the visitor towards the key action.

For B2B SaaS, especially something like accounting software (like in one case we looked at), changing systems is a big, disruptive deal for a business. People don't do it lightly. They need a lot of reassurance and a very strong reason to switch or even to invest time in learning more.

The critical thing is your 'offer' on the landing page. What do you want that visitor to do? Sign up for a demo? Request a consultation? Download a guide? For SaaS, hands down, offering a free trial or a Freemium option usually works miles better than just a demo request. Why? Because it lowers the barrier to entry significantly. Asking someone to book a demo requires a commitment of time and interaction with a salesperson, which they might not be ready for. A free trial lets them explore on their own terms, reducing perceived pressure and risk.

Looking at the accounting system example again, a major point was the lack of a free trial when competitors offered several months. That's a massive competitive disadvantage that no amount of ad spend alone can fix. You need an offer that makes it a "no-brainer" for someone interested in solving the problem your software addresses to at least try it out.

Beyond the offer itself, the landing page copy needs to be incredibly persuasive. It shouldn't just list features, it needs to speak directly to the pain points of small businesses struggling with their current system and highlight the benefits of yours. We often bring in a specialised copywriter for our SaaS clients because getting this right is absolutely crucial for conversion rates. Generic, weak, or unclear copy will absolutely kill performance and make your CPL skyrocket.

Also, does your website look professional and trustworthy? For businesses, security, reliability, and professionalism are huge concerns, especially with sensitive things like accounting. Trust signals like testimonials, case studies (even short blurbs about how other small businesses benefited), clear contact information, privacy policy, and secure site badges can make a big difference. A cluttered or slow-loading site also erodes trust and patience.

Improving your website's conversion rate means that for the same number of clicks, you'll get significantly more leads, which directly lowers your cost per lead. Even a small increase in conversion rate can dramatically impact your bottom line.

Let's talk about your targeting...

While I think the website/offer is the primary suspect here, it's worth considering if your targeting is bringing in the *right* kind of traffic. Google Search Ads works best when you're reaching people with high intent – meaning they are actively searching for a solution like yours right now.

Are the keywords you're bidding on specific enough? Are you targeting broad terms that might bring in people who are just researching, not ready to buy or even try? For small businesses searching for accounting software, keywords like "best accounting software small business", "accounting software for startups", "migrate from [competitor name]", or even problem-focused terms like "how to simplify small business bookkeeping" would be good starting points for high intent. Bidding on very general terms like "accounting software" could bring in students, job seekers, or people just browsing, who are unlikely to convert into qualified leads, let alone customers.

Are you using negative keywords effectively? This is massive for search campaigns. You need to tell Google which searches you *don't* want your ad to show for. For instance, if you only offer cloud-based software, you'd add "desktop", "free download", "pirated", etc. If you only serve businesses in the UK, you'd add other countries. This prevents wasted clicks from irrelevant searches.

It's possible you're getting clicks from people who sound right on paper (e.g., "small business owner searching for software") but whose search query actually indicates low intent or a need your software doesn't meet. Refining your keyword list and continually adding negative keywords is key to improving traffic quality and lowering CPL.

When expert help comes in...

You're asking about agencies and how to vet them, which is a completely valid question, especially after a tough experience managing it internally. It sounds like you've hit a wall, and that's understandable. Paid advertising, especially for complex B2B products, is genuinely difficult and requires specific expertise and ongoing work.

An experienced agency specialising in B2B SaaS Google Ads can bring a lot to the table. They've likely seen similar situations, know the common pitfalls, and understand how to structure campaigns, find high-intent keywords, write compelling ad copy *that matches user intent*, and optimise landing pages (or advise you on how to improve yours) for conversion.

They also have experience with split testing – constantly trying different ad variations, landing page elements, and targeting approaches to find what works best. This continuous testing and optimisation is what drives performance improvements over time. What you're describing sounds like a campaign that hasn't been through this rigorous optimisation process.

Now, regarding vetting... it's tough, you're right. The case studies *can* sound too good to be true, and there are definitely agencies out there who over-promise or aren't genuinely expert in B2B SaaS. The fact you're seeing competitors succeed on Google is a good sign that the channel *can* work; it's just about executing it correctly for your specific offer.

Instead of just looking at impressive top-line numbers (like huge ROAS for eCommerce, which is very different from B2B lead gen), try to find an agency that specifically highlights their experience and results with B2B SaaS lead generation. Ask them about their typical CPLs for B2B SaaS, what conversion rates they aim for on landing pages, and how they approach testing offers (like free trials vs. demos) and improving website performance. Someone with real B2B SaaS experience will understand your sales cycle challenges and focus on qualified leads and customer acquisition cost, not just clicks or even leads that don't convert down the line.

Ultimately, hiring an agency is about leveraging their experience to achieve results faster and more efficiently than you could internally, especially when you're facing significant challenges like a $300 CPL. They should be able to identify the likely culprits (website, offer, targeting) quickly and implement fixes based on their knowledge of what works in your sector. For instance, we've had SaaS clients where we've been able to reduce cost per lead significantly just by refining the offer and improving the landing page, sometimes quite quickly. Getting CPL down to, say, $50-$100 (which is more typical for many B2B SaaS niches we've worked in, though it varies hugely) fundamentally changes the viability of the channel, even with a 3% customer conversion rate.

However, a good agency will also be honest with you. If your offer fundamentally isn't competitive (like not offering a trial when everyone else does) or your pricing/sales process is broken, no amount of ad spend will fix that. They should work *with* you to improve the entire funnel, not just manage the ads in isolation.

Here’s a quick overview of where I think you need to focus action:

Ultimately, tackling the conversion side first is likely your best bet to see a significant shift in your numbers. Getting your website and offer right will make any future advertising efforts, whether internal or with an agency, far more effective and cost-efficient. Once the fundamentals are stronger, scaling becomes possible, and that's where experienced help can really accelerate your growth and fine-tune performance in ways that are hard to replicate without having managed many similar campaigns.

It's definitely a process, but focusing on these core areas should start to move the needle. If you'd like to chat through your specific situation in more detail, I'm happy to book in a free consultation to give you some more tailored pointers.
