What Is a Landing Page? And How I'd Build One That Converts

I wrote the first version of this post in 2020. Reading it now hurts a little. It told you a landing page "speaks directly to your visitor's heart", quoted a Google statistic about smartphone searches, and linked to my contact page four times. It never once explained how to actually build one.

So this is the rewrite. Same question, but answered the way I'd answer a client today.

A landing page is the page someone lands on after clicking an ad, an email link or a social post, and it's built for exactly one action. That's the whole definition. The interesting part is why so many of them don't work, and what to do about it.

What a Landing Page Is (and What It Isn't)

Look at your homepage for a second. Navigation bar, services section, an about blurb, maybe a blog feed, and a footer full of more links. Every single one of those is an exit.

A landing page removes the exits. It talks about one offer and asks for one thing. Usually that means no main navigation and nothing in the sidebar pulling people away.

Technically, any page a visitor arrives on is a landing page. Google Analytics uses the word that way. In marketing, though, it means a page you built for a specific campaign. There are two common kinds:

• Lead generation pages ask for contact details through a form: a quote request, a free checklist, a consultation booking.
• Click-through pages warm someone up and send them to the next step, like a checkout, a signup or an app store listing.

Both follow the same rule. If a visitor can do five different things on the page, most of them will do none.

Why Your Homepage Is Burning Your Ad Budget

Google Ads scores your keywords on three things: expected click-through rate, ad relevance and landing page experience. That third one is your page, and it directly affects your Quality Score, which affects how much you pay per click.

Google judges landing page experience on whether the page matches what the ad promised, whether it loads fast and works on a phone, and whether it's clear who runs the site. A below-average rating means you pay more for the same clicks and show up less often.

Now picture someone searching for "emergency plumber Augsburg". They click an ad that says "Plumber at your door in 60 minutes". They land on a homepage that opens with the company's founding story and a slider of bathroom renovations. The ad made a promise, and the page forgot about it. That person hits the back button and you just paid for the click.

Sending all your paid traffic to the homepage is one of the most common ad mistakes there is. It's also one of the cheapest to fix.

What Actually Makes a Landing Page Convert

Unbounce analyzed over 41,000 landing pages (data from July 2023 to July 2024) and found a median conversion rate of 6.6% across industries. Half the pages did better, half did worse. These are the boring things I'd check first on any landing page that sits below that line.

Message match

The headline should repeat the promise of the ad or email that brought people there, ideally in the same words. If the ad says "Free SEO checklist for contractors", the headline says "Free SEO checklist for contractors". Not "Welcome to our website". People decide in a few seconds whether they're in the right place, and matching words is how you tell them they are.

One action, repeated

Pick one call to action. Put it above the fold, then again after the sections that answer objections. Same button text every time. A "Book a call" button next to a "Download our brochure" link next to a newsletter signup splits attention three ways and wins none of them.

Copy a twelve-year-old understands

In the same Unbounce report, pages written at a 5th to 7th grade reading level had a median conversion rate of 11.1%. Pages written at a college reading level: 5.3%. Short sentences, common words, no jargon. My 2020 version of this post would have failed that test badly.

Proof right next to the button

Real reviews with names, client logos, a photo of the actual person who will do the work, a concrete result. Put them close to where the decision happens, not on a separate testimonials page nobody clicks. And only use proof that's real. A made-up testimonial is worse than none.

Short forms

Every extra form field is another reason to leave. Name, email and one question about the project is usually enough for a first contact. You can ask the other ten questions on the call.

Speed

A landing page that takes four seconds to show its headline on a phone has already lost a chunk of the people you paid for. Google's Core Web Vitals give you clear targets: Largest Contentful Paint under 2.5 seconds, Interaction to Next Paint under 200 milliseconds, Cumulative Layout Shift under 0.1. If you've never checked your numbers, start with my guide to testing website speed.

How I'd Build a Landing Page Today

In 2020 my answer would have been WordPress plus a page builder. I spent years comparing builders. Today a landing page is the clearest case for Astro that I know of, and I wrote about how I choose between WordPress, Next.js and Astro for client projects if you want the longer reasoning.

A landing page is one page of mostly text and images that rarely changes. Astro builds it into plain HTML and ships zero JavaScript unless you ask for it. There's no database to query and no plugin to update before the headline shows up. That's exactly what the speed section above asks for.

For hosting I'd put it on Cloudflare. Cloudflare now recommends Workers with static assets for new projects instead of Pages, and serving static files there doesn't cost you anything. Either one works fine for a single landing page.

The only dynamic part is the form. A static page can't receive data on its own, so the submission has to go somewhere. I wrote up how I add a contact form to a static Astro site without turning on server rendering, and that's the setup I'd reuse here.

The order matters more than the tools, though. I'd write the headline and the call to action in a plain text document first, before anyone opens a design tool. If the copy doesn't work as plain text, a nice layout won't save it.

If you're not a developer and you just want to test an offer this week, a hosted landing page builder is fine. Everything in the previous section applies no matter what you build it with.

How to Tell If It's Working

That 6.6% median is a reference point, not a goal. A page offering a free checklist and a page asking for a five-figure project will never convert at the same rate, and they shouldn't be compared.

Track conversions per traffic source. Google Ads visitors, email subscribers, LinkedIn clicks and Meta ad clicks behave very differently, and one blended number hides all of that.

Then watch what people do. Microsoft Clarity is free, has no traffic cap, and gives you heatmaps and session recordings. If your visitors are in the EU, it sets cookies, so it belongs behind your consent banner. Watching ten recordings of people who left without converting usually tells you more than a month of staring at dashboards. Maybe they never scroll past the hero. Maybe they start the form and quit at the phone number field. If a lot of people leave immediately, the problems are often the same ones I cover in my bounce rate guide.

A/B testing gets recommended everywhere, but it needs traffic. With a few hundred visitors a month, a split test on button color will run for ages and still tell you nothing reliable. At that size I'd change one big thing, like the headline or the offer itself, and compare the before and after. It's noisy, and I don't have a cleaner answer for small sites.

When You Don't Need a Landing Page

If you're not running ads, email campaigns or anything else that sends people to a specific offer, you probably don't need a dedicated landing page.

Landing pages are built for paid and campaign traffic. Stripping out navigation and keeping text short is great for conversions and pretty bad for organic search. For a local business that gets most of its customers from Google, a solid service page for each service you offer does more work. It can rank and convert without an ad budget behind it.

The opposite is also true. If you're spending money on ads and sending the clicks to your homepage, a landing page is probably the first thing I'd build for you, before any redesign.

I can't promise a landing page fixes a weak offer. Nothing does. What I can do is build one that loads fast and gets tracked properly, so we can see whether the offer or the page is the problem. If you want that for your next campaign, let's talk.
