Landing Page Optimisation: The Principles That Actually Move Conversion Rates

Landing Page Optimisation: The Principles That Actually Move Conversion Rates

Your landing page is where advertising investment turns into revenue, or doesn’t. Most businesses put nearly all their attention into driving traffic and very little into what happens after the click.

That imbalance is expensive. Doubling your conversion rate has the same effect on enquiries as doubling your ad budget, but it costs a fraction as much and the improvement compounds every month afterwards.

This guide covers the principles that consistently move conversion rates, based on designing and testing landing pages for Australian businesses across a range of industries.

Start by Knowing Your Baseline

Before changing anything, record your current conversion rate: enquiries divided by landing page visitors, over at least a month.

Without that number, you can’t tell whether a redesign helped or hurt. We’ve seen businesses rebuild a page, feel pleased with how it looks, and never notice enquiries fell 30%.

The Headline Does Most of the Work

Visitors decide within about three seconds whether to stay. The headline has to answer one question: what’s in this for me?

Weak: “Welcome to HHP Design — Sydney’s Digital Agency”

Stronger: “More Enquiries From Your Google Ads, Without a Bigger Budget”

The difference is perspective. One describes the company, the other describes the customer’s outcome. If your headline could be swapped onto a competitor’s page without anyone noticing, it isn’t doing its job.

Trust Signals Belong Above the Fold

People need reasons to believe before they’ll act, and they need them early.

WorksDoesn’t work
“600+ Shopify stores built”“Years of experience”
Named client logosGeneric stock imagery
Certified Shopify Partner badge“Award-winning” with no award named
Reviews with full names“J.S., happy customer”

The pattern is specificity. Claims a visitor could verify carry weight; claims anyone could make carry none. Our case studies are structured the same way — specific numbers rather than adjectives.

Call-to-Action Placement

Use a minimum of three placements on any landing page: above the fold, immediately after your core value proposition, and at the foot of the page.

More than half of visitors never scroll to the bottom. If that’s where your only enquiry button sits, you’re losing most of your potential conversions before they ever see it.

Keep the wording consistent across all three. Three different phrasings read as three different offers.

Form Length, Particularly on Mobile

Every additional field reduces completion. For a first-contact form, name and phone number is usually enough — gather the rest during the follow-up call.

The objection we hear is that short forms produce lower-quality enquiries. In practice, they produce more enquiries, and qualification is a two-minute phone conversation rather than a barrier you place in front of every prospective customer.

Page Speed

A landing page taking more than three seconds on mobile loses a meaningful share of visitors before any content appears. Check with Google PageSpeed Insights and aim for 70 or above on mobile. If you’re on Shopify, our complete speed optimisation guide covers the specific causes.

This matters most for paid traffic, where every lost visitor was paid for individually.

Test One Thing at a Time

The temptation after reading an article like this is to change everything at once. Resist it. If you rewrite the headline, shorten the form and move the buttons simultaneously, you’ll never know which change produced the result — or which one hurt.

Test in this order, since it reflects the size of the typical effect: headline, then form length, then the offer itself, then layout. Our before and after walkthrough shows how a page went from 1.2% to 2.8% using exactly this sequence.

Where to Start

This week: Record your current conversion rate. Rewrite the headline to describe the customer’s outcome rather than your business.

This month: Cut the form to two or three fields, add a call-to-action above the fold, and move your strongest trust signals up beside it.

Next 90 days: Run one test at a time, allowing enough conversions for each result to be readable before moving to the next.

Frequently Asked Questions

What conversion rate should I be aiming for?

It varies by industry and price point, but Australian service businesses receiving relevant traffic typically sit between 3% and 10%. Below 1% usually points to a structural problem rather than a copy problem.

How long should a landing page be?

Long enough to answer the questions a buyer has before enquiring, and no longer. Higher-priced or more considered purchases generally need more page; simple, urgent services need less.

Should I use video on a landing page?

Only if it loads quickly and isn’t set to autoplay with sound. A slow-loading video above the fold usually costs more conversions than the video earns.

How much traffic do I need before A/B testing is worthwhile?

You need conversions rather than clicks to read a result. As a rough guide, wait for at least 100 clicks and a handful of conversions per version.

Can I just send traffic to my homepage instead?

Rarely a good idea. Homepages serve every audience, so they serve no particular ad audience well. A dedicated page matched to the ad almost always outperforms it.
