A landing page is not a small website. A marketing site invites people to wander; a landing page is built for one purpose and measured by one question — how many of the people who arrived did the thing you asked them to do.
What is interesting is that most pages do not fail on design. They fail on decisions that are easy to miss: how many fields are in the form, how long the page takes to load on a phone, and what exactly happens to an enquiry in the two minutes after it is sent.
The first three seconds
Someone arrived from an ad, a search, or a link, and they need two things immediately: what you are offering, and why it concerns them. One headline and one sentence beneath it do nearly all of that work.
The test is simple. Show the top of the page to somebody who does not know the business, take it away, and ask them what they saw. If they cannot say, the problem is the wording rather than the amount of information further down.
A common mistake is writing the headline about yourself. The visitor is not looking for who you are; they are looking for what they get.
One action, and few fields
A landing page has one action. If it also has a newsletter signup, a guide to download, and a link back to the homepage, then it has none of them — every extra option is another decision the visitor has to make.
And every field in the form has a price. A name, a phone number or an email, and a free-text line is usually enough to start a conversation. Company size, budget, and headcount can be asked on the call, where the answers will also be more accurate.
If an extra field genuinely filters out enquiries you do not want, it may be worth it. Just know you are trading volume for quality, and measure whether the trade paid.
Proof that can be checked
An unattributed testimonial, the logo of a company you never actually worked with, or a number nobody can explain the source of — all of these work against you. A visitor who spots one inflated proof stops believing the rest of the page.
What does work: a full name and role under a quote, a number you can explain how you measured, and client logos you have permission to use. Three real ones beat twelve impressive ones.
Speed is part of the conversion
Most landing page traffic arrives on a phone, and often on a mobile network rather than wifi. A slow page loses people before they have read the headline — they did not see a bad offer, they saw nothing at all.
It is also not only about conversion: speed is something Google measures directly, which means a slow page both costs more in advertising and ranks lower in organic search.
In practice this comes down to unglamorous things — images at the right size in the right format, few third-party scripts, and fonts that do not block the page from painting. There is no trick here, only work.
What happens after the click
This is where the real difference sits, and where most pages stop. The form submits, an email lands in a shared inbox, and somebody will get to it. Meanwhile the lead cools, and the competitor who replied within ten minutes has already spoken to them.
What can be wired instead: the enquiry goes straight into your CRM carrying the source it came from, gets an owner and an automatic reminder, and a confirmation email goes out immediately. Automation tools like n8n, Make or Zapier connect those pieces without building a whole system.
On top of that you can add a layer of judgment: a model that classifies the enquiry from what was written in it, flags whether it is urgent or irrelevant, and drafts a first reply. A person still sends that reply — but they send it within minutes rather than in two days.
And on a sales page, payment should happen on the page. Every hop to an external site is another chance to reconsider.
Without measurement it is not a landing page
A landing page without measurement is a guess that costs money. The minimum is knowing how many people arrived, how many submitted, and from which source — and if you are advertising, what each lead cost you per channel.
The number that actually matters is not how many leads but how many became customers. A page producing a hundred enquiries none of which are relevant is worse than one producing ten good ones, and without connecting the measurement to your CRM you cannot tell which of those happened.
And when you change something — a headline, a button, the number of fields — change one thing at a time and give it enough traffic for the difference to be real. Changing two things together tells you the page improved without telling you what improved it.
A good landing page is a stack of unglamorous decisions: one message, one action, few fields, fast loading, honest proof, and wiring that moves the enquiry somewhere a person will handle it quickly.
The part you can see — the headline and the button — is a few hours of work. The part you cannot see is what decides whether the money you spent on advertising comes back.
