Paid traffic and landing page optimisation

Before you increase your ad budget, test what visitors see after they click

Written by Neil Webley · Last updated

If you pay for Google Ads, Facebook Ads, LinkedIn Ads or any other traffic, every visitor costs money. A/B testing helps you find out whether a better landing page could turn more of those paid clicks into enquiries, bookings or sales.

More traffic is not always the answer. Sometimes the biggest opportunity is getting more value from the traffic you already have. For a broader CRO overview, see how to make your website work harder.

You are already paying to get people to your website

Many small businesses spend money getting visitors to their website. That might be through Google Ads, Facebook Ads, Instagram Ads, LinkedIn Ads, directory listings, sponsored posts or local campaigns.

The usual instinct is to ask: how do we get more visitors?

But there is another question that can be just as important:

Are we converting enough of the visitors we already pay for?

If your landing page is unclear, unconvincing or missing something important, buying more traffic may simply send more people into the same problem.

Small conversion improvements can make a real difference

Imagine you spend enough on ads to bring 1,000 visitors to your landing page. If 2% of those visitors enquire, book or buy, you get 20 conversions.

Simple example

2%

1,000 visitors produce 20 enquiries.

2.5%

1,000 visitors produce 25 enquiries.

That difference looks tiny on paper. It is only half a percentage point. But in this example, it creates five extra enquiries from the same advertising spend.

If each enquiry is worth £50, £100, £500 or more to your business, that small improvement can become very real very quickly.

Why paid traffic is perfect for practical A/B testing

Paid traffic gives you a steady stream of visitors. Instead of sending all of them to one version of a page, you can split them between two versions and measure what happens.

Version A

Your current landing page stays live for part of your visitors. This gives you a fair comparison point.

Version B

A changed version is shown to another group. That might be a new headline, offer, CTA, trust message or layout.

Compare results

You measure which version gets more enquiries, sales, bookings, calls or other important actions.

The danger of changing the page and hoping

Without A/B testing, the usual approach is simple. You change the landing page, wait a few weeks, then look at whether sales or enquiries improved.

The problem is that the world changed at the same time.

Your ad targeting may have changed. Your budget may have changed. A competitor may have run out of stock. The weather may have helped or hurt demand. Payday may have arrived. The economy, seasonality, fashion, news, school holidays and simple luck may all have influenced your results.

A before-and-after comparison can make a website change feel successful even when something else caused the improvement.

A/B testing is different because both versions are shown during the same period. They experience the same days, the same campaigns, the same seasonal conditions and the same wider market. The main intended difference is the page change you are testing.

What should you test on a paid landing page?

You do not need to redesign the whole page. Start with changes that might affect whether visitors understand, trust and act on your offer.

The headline

Does it instantly explain the value of what you offer, or is it vague and forgettable?

The call to action

Does the button make the next step obvious, specific and low-friction?

The offer

Would a clearer benefit, stronger guarantee or more relevant incentive increase responses?

Trust signals

Could reviews, testimonials, accreditations or examples reduce hesitation?

Form length

Are you asking for more information than you really need at this stage?

Page focus

Is the page trying to do too many things, or does it guide people towards one clear action?

Before spending more, improve what happens after the click

Increasing your ad budget can bring more visitors, but it can also increase waste if the landing page is not doing its job.

  • Test one meaningful change at a time
  • Measure enquiries, sales or other real outcomes
  • Use paid traffic to learn faster
  • Send future visitors to the version that performs better
How do you know if a website change worked?

The goal is not just more traffic

More traffic is useful when your page already converts well. But if the page is underperforming, optimisation can improve the return from every future visitor.

The goal is better return on ad spend

A better converting landing page can reduce your cost per enquiry, cost per booking or cost per sale without needing to pay for more clicks.
