The 5-Day Landing Page: What to Build Before You Spend on Ads

Before you spend on ads, build one landing page that makes one offer, to one audience, with one action, and make it fast on a phone. The median landing page converts 6.6% of visitors, and the average Google Ads lead now costs about $70, so a weak page wastes money on every click. A focused page takes about five days.

Disclosure: I run Ship It Live, a fixed-price design and development service, so I have a stake in this topic. Every number below links to its source; the build stories are from my own products, not client work.

Why build a landing page before running ads?

Because ads buy visits, and the page decides what those visits are worth. Paid clicks aren't cheap: across 16,446 campaigns in LocaliQ's 2025 benchmarks, the average Google Ads click cost $5.26 and the average lead cost $70.11.

At those prices, sending ads to your homepage is expensive. A homepage has to serve everyone: investors, job seekers, existing customers, the curious. An ad visitor came for one thing. A landing page gives them that thing and nothing else.

What conversion rate should a landing page get?

There's no universal number, but there is a useful benchmark. Unbounce's Conversion Benchmark Report, built from 41,000 landing pages and 57 million conversions, puts the median at 6.6% across industries. SaaS pages sat lower, at a 3.8% median.

Two findings from the same report are worth acting on:

• Simpler writing converted better. Pages written at a fifth-to-seventh-grade reading level had an 11.1% median conversion rate, against 5.3% for pages that read at college level.
• Traffic source matters a lot. Email traffic converted far better than most paid channels, because those visitors already know you.

Use the benchmark to spot a broken page, not to set a target. A page converting at 0.5% has a problem worth fixing before you add budget.

What should a landing page for ads include?

One offer, argued in the order a sceptical visitor needs. This is the structure we use:

Section	Its job
Headline	Name the outcome the visitor wants, in their words, matching the ad they clicked
Subheadline	Who it's for and how it works, in one sentence
One call to action	The single next step, repeated down the page, never competing with a second one
Proof	Real reviews, logos or numbers you can back up
How it works	Three or four steps, so the visitor can picture using it
Objections	Price, time, risk: answered before they're asked
Final call to action	The same action again, for visitors who read everything

Cut the navigation menu. Every link that leads away from the action is a way out.

Does page speed affect conversions?

Yes, measurably. In a study of mobile sites commissioned by Google and run by Deloitte, a 0.1-second improvement in mobile site speed increased conversion rates by 8.4% for retail sites and 10.1% for travel sites.

Most ad clicks happen on phones, often on mobile data. The usual slow-downs on landing pages are a huge hero video, uncompressed images, too many fonts and animations that hide the content until scripts load. Test on a mid-range phone over mobile data, not on your laptop.

How do you measure a landing page honestly?

Count only real visitors, and know where each one came from. Three habits keep the numbers honest:

1. Tag every ad link with UTM parameters (source, medium and campaign), so each lead shows which ad and campaign brought them.
2. Only track the live domain. Preview links, staging copies and your own testing shouldn't count. On our own products, analytics only switches on for the production domain.
3. Filter out bots. Automated browsers, uptime checks and link previewers load pages too. We found that automated browser visits were being counted as real traffic on one of our sites, and they made the numbers look better than they were.

Then send a test lead through the whole path, form to inbox or WhatsApp, before you spend a cent. A form that silently fails is the most expensive bug a landing page can have.

How much traffic do you need to test a landing page?

Enough to see a difference that isn't luck. A rough way to plan it: decide how many leads would tell you something, then work backwards.

Using the sourced averages above, here's what 20 leads would cost at different conversion rates:

Page converts at	Visitors for 20 leads	Ad spend at $5.26 a click
2%	1,000	$5,260
3.8% (SaaS median)	about 530	about $2,770
6.6% (all-industry median)	about 300	about $1,580
10%	200	$1,052

The table makes the point plainly: the same 20 leads cost five times more on a weak page than on a strong one. Improving the page is usually the cheapest marketing you can buy.

When you test, change one thing at a time and start with the biggest levers:

1. The headline, because every visitor reads it.
2. The offer itself: a free trial, a demo, a price, a guarantee.
3. The call to action, both the wording and how much it asks for.
4. Proof near the top, such as a rating or a recognisable customer.

Button colours and small layout tweaks rarely matter until those four are right.

What does a 5-day landing page sprint look like?

Our landing page in 5 days sprint is a fixed $700:

Day	Stage	What happens
1	Structure	What the page must prove, in what order, and the single action
2–3	Design	The full page designed mobile-first, with custom graphics where stock would undersell it
4	Build	Coded, responsive and fast, with lead capture wired to where you actually check
5	Launch	Live on your domain, tracking connected, and a test lead sent end to end

Day one matters most. The order the page makes its argument in decides whether it converts, so it's settled before any design. For what pages cost on other routes, from templates to agencies, see how much a landing page costs.

A landing page can't rescue an offer that isn't clear yet. If you don't know exactly what you're selling and to whom, settle that first.
