Landing Page Conversion Rate Matters More Than Your Ads

How one landing page change cut cost per lead by 4.7x

A marketer was hired to fix a client's Google Ads campaigns. The brief was straightforward: ad performance was declining, CPL had crept up to EUR 19, and the client wanted it back under control.

The marketer looked at the ads. They were fine. Not perfect, but fine. Good enough click-through rates. Decent relevance scores. The targeting was reasonable.

Then they looked at the landing page.

A single long-form page with a 15-field lead capture form. Name, email, phone, company, job title, company size, industry, budget range, timeline, and six more fields that most visitors would never bother completing. No progress indicator. No explanation of what happens after you submit. Just a wall of fields and a "Submit" button.

The marketer didn't touch the ads. Instead, they replaced the form with a multi-step quiz funnel.

Same data collection. Same fields, broken into five conversational steps. A progress bar at the top. A "See your personalised results" CTA at the end instead of "Submit your application."

Later, the marketer did go back and overhaul the creative. That added another 1.14x improvement on top. Meaningful, but a fraction of what the landing page change delivered.

The maths tells the whole story. The landing page change was worth 4.7x. The ad creative change was worth 1.14x. If you only had time to do one, there's no contest.

Landing page conversion rate vs ad creative: where to optimise first

Let's make this concrete.

Say you're spending EUR 5,000 per month on ads. Your ads get a 2% click-through rate and your landing page converts at 3%. That gives you roughly 30 leads per month at EUR 167 per lead.

Scenario A: You improve your ad creative. Click-through rate goes from 2% to 2.5%. You get more clicks for the same spend, but the landing page still converts at 3%. Your CPL drops to about EUR 133. A solid 20% improvement.

Scenario B: You improve your landing page. The click-through rate stays at 2%, but the landing page conversion rate goes from 3% to 6%. Your CPL drops to EUR 83. A 50% improvement.

Scenario C: You do both. CPL drops to about EUR 67. But notice where the compounding happens. The landing page improvement does most of the heavy lifting.

This isn't hypothetical. This is how the maths works every time. Ad creative improvements are additive. Landing page improvements are multiplicative.

Quiz funnels vs lead forms: same data, higher conversion rate

The quiz funnel isn't a new idea. But it's having a moment, and for good reason. It works because it aligns with how people actually behave online.

A traditional lead form asks the visitor to do work upfront with no clear reward. Fill in your details, hit submit, and maybe someone will email you back. It's a transaction where all the effort is on the visitor's side.

A quiz funnel flips this dynamic. It gives before it asks.

When to optimise your landing page before touching your ads

Not every account needs a landing page overhaul. Sometimes the ads really are the problem. But more often than you'd think, the page is the bottleneck.

Here's a diagnostic checklist. If you check three or more of these boxes, start with the landing page.

The landing page diagnostic

• Your form has more than five fields. Every field you add reduces completion rates. If you're asking for information you don't immediately need to qualify the lead, remove it.
• There's no progress indicator on multi-step forms. Visitors need to know how much effort remains. Without a progress bar, each new step feels like a surprise.
• Your mobile conversion rate is significantly lower than desktop. Most paid traffic, especially from Meta, is mobile. If your page wasn't designed for a thumb, you're losing the majority of your visitors.
• The headline on the page doesn't match the ad. This is called "message match," and it's one of the most common mistakes. If your ad promises "Get a free audit of your Google Ads account" and the landing page headline says "Welcome to our marketing agency," you've broken the visitor's trust before they've even scrolled.
• You're using a generic "Contact Us" or "Submit" CTA. These tell the visitor nothing about what happens next. A good CTA describes the outcome: "See your results," "Get your free report," "Book a 15-minute call."
• Your page takes more than three seconds to load on mobile. Every second of load time costs you conversions. Google's own data shows that 53% of mobile visitors leave a page that takes longer than three seconds to load.
• You haven't looked at your competitor's landing pages recently. Open an incognito window, search for your target keywords, and click the top three ads. If their pages are significantly better than yours, your conversion rate gap isn't a creative problem.
• Your bounce rate from paid traffic is above 70%. If seven out of ten people leave without doing anything, the problem isn't the audience. It's the page.

How a higher landing page conversion rate improves ad algorithms

There's a second-order effect that most marketers miss.

Modern ad platforms are increasingly algorithm-driven. Meta's Advantage+ campaigns, Google's Performance Max, broad match keywords with Smart Bidding. These systems optimise toward conversions. The better your conversion data, the better the algorithm performs.

A landing page that converts at 3% sends the algorithm a different signal than one that converts at 8%. With more conversions from the same traffic, the algorithm has more data points to learn from. It identifies patterns faster. It finds similar audiences more efficiently. It allocates budget more effectively.

This creates a virtuous cycle:

This is why the marketer in the earlier example saw such a dramatic drop. The quiz funnel didn't just convert more people. It gave Google's bidding algorithm cleaner, faster conversion data. The algorithm could optimise delivery more effectively because it had more examples of what a converting user looks like.

If you're running broad targeting strategies, and in 2026 you should be, your landing page is the single most important variable for algorithm performance. Broad targeting means you're trusting the algorithm to find the right people. A high-converting page is how you teach it who the right people are. This is also why conversion tracking setup is so critical -- without clean conversion data flowing back, no amount of landing page improvement can help the algorithm learn.

Of course, a better-converting page also means your budget gets spent faster. It's worth keeping an eye on ad budget pacing so you don't blow through your monthly budget in week two -- tools like aubado's Budget Checker can automate that monitoring across Google, Meta, and Microsoft Ads.

7 landing page mistakes that kill your conversion rate

These are the landing page optimisation mistakes that silently drain budgets without anyone noticing, because the marketers responsible are too busy A/B testing ad thumbnails.

1. Too many form fields

This is the most common and the most expensive mistake. Every additional field reduces form completion rates by roughly 4 to 5 percent. A 15-field form with a 2% conversion rate could become a 5-field form with an 8% conversion rate.

Ask yourself: do you really need their phone number, company size, and job title before your first conversation? Most of that information can be collected later, or inferred from their email domain.

2. No progress indicators

If your form has more than one step, show the visitor where they are. "Step 2 of 4" or a simple progress bar. Without it, each new step feels potentially endless, and the visitor's most rational move is to leave.

3. Message mismatch between ad and page

The visitor clicked your ad because something specific caught their attention. If the landing page doesn't immediately reinforce that same message, you've broken the promise.

This doesn't mean the page needs to repeat the ad word for word. But the core offer, the headline, and the visual tone should feel continuous. The visitor should never wonder, "Did I click the right link?"

4. Ignoring mobile experience

This one surprises people. Most marketers design their landing pages on a laptop. Then 80% of their Meta traffic arrives on a phone. Tiny text, forms that require horizontal scrolling, buttons too small to tap. These aren't design problems. They're conversion problems.

Test your landing page on your phone. Actually fill out the form. Time yourself. If it takes more than 30 seconds or requires pinching and zooming, you have work to do.

5. The generic CTA

"Submit." "Contact us." "Get started."

These are placeholder labels, not calls to action. A good CTA answers the visitor's question: "What do I get when I click this?"

The specific version outperforms the generic version every time. Not by a little. By a lot.

6. No social proof near the conversion point

Testimonials, client logos, case study snippets, review scores. Place them near the form or CTA, not buried at the bottom of the page. The moment of conversion is the moment of highest doubt. Social proof reduces that doubt.

7. Slow page speed

A landing page is not a website. It doesn't need your full navigation, your footer with 30 links, or your chat widget. Strip it down. Every element that isn't directly contributing to the conversion is either neutral or harmful.

Faster pages convert better. Full stop.

The conversion rate optimisation order that actually works

If you take one thing from this piece, let it be this: optimise from the bottom of the funnel up, not from the top down.

This is partly why we built aubado the way we did -- small, modular apps that handle the ad monitoring and budget tracking side of things, so you can spend your time on work like landing page optimisation that actually moves the needle.

Most marketers do this in reverse. They start with the thing that's most visible (the ad) and ignore the thing that has the most impact (the page).

The marketer who dropped CPL from EUR 19 to EUR 4 didn't have a secret trick. They didn't discover a hidden audience or write a magically persuasive ad. They looked at where the funnel was actually breaking, fixed the foundation, and let the improvement compound through everything above it.

Your ads are probably fine. Your landing page probably isn't. Start there. And once the page is working, let something like aubado keep watch on the ads so you don't have to.
