Website conversion optimisation: 12 proven tactics

Your website is getting traffic but not converting visitors into leads. Sound familiar? You are not alone. Across 3,000+ projects we have delivered at Apexure, the most common problem clients bring us is not a traffic problem. It is a conversion problem. The visitors are there. They just are not taking the next step. Website conversion optimisation (CRO) is the systematic process of increasing the percentage of visitors who complete a desired action, whether that is filling out a form, booking a demo, or making a purchase. The good news: even small improvements compound quickly. A jump from 2% to 4% conversion rate doubles your leads without spending an extra penny on ads. In this guide, we share 12 conversion tactics we use every day across client projects, from startups to household names like a listed company and Rocket Companies, and IDEXX.

The conversion rate multiplier effect, a small CR improvement halves your cost per lead.

What is website conversion optimisation?

Website conversion optimisation (also called CRO) is the practice of making changes to your website so a higher percentage of visitors take a desired action. That action might be:

• Submitting a lead generation form
• Booking a consultation or demo
• Signing up for a free trial
• Making a purchase
• Downloading a resource CRO is not about getting more traffic. It is about getting more value from the traffic you already have. This makes it one of the highest-ROI marketing activities available, because the incremental cost of converting an additional visitor is close to zero.

How to track website conversions in GA4

If your analytics are not tracking conversions, every optimisation decision is a guess. Here is the modern approach using Google Analytics 4:

1. Set up a thank-you page, redirect users to a dedicated confirmation page after form submission. This gives you a clean destination URL to track.
2. Create a GA4 event, in GA4, go to Admin → Events → Create Event. Name it something like generate_lead and set the condition to page_location contains /thank-you.
3. Mark it as a key event, toggle the event as a "key event" (formerly called a conversion) so it appears in your reports and can be imported into Google Ads.
4. Verify with real-time reports, submit a test form and check the GA4 Realtime report to confirm the event fires correctly.

If you are using a landing page builder like Unbounce or a CMS like WordPress, most platforms have built-in thank-you page redirection. For more advanced tracking, such as form field events or scroll depth, use Google Tag Manager.

12 website conversion optimisation tactics that work

These are not theoretical tips. Each tactic below comes from patterns we have observed across 3,000+ pages and the A/B tests we have run at Apexure.

1. Make your Call-to-Action buttons impossible to miss

The CTA button is the single most important element on any conversion-focused page. If visitors cannot find it, or it does not look clickable, your conversion rate suffers.

Five elements that make a CTA button convert: contrast, action copy, directional cue, clear value, and tappable size.

What we see working across projects:

• Contrast wins clicks, the CTA should be the most visually prominent element in its section. Never use the same colour as your navigation or body links.
• Create urgency, phrases like “Get Started Today” or “Book Your Free Audit” outperform vague labels like “Submit” or “Click Here”.
• Place trust signals near the button, move badges, star ratings, or a short testimonial quote close to the CTA to reduce friction at the decision point.
• Test position, above the fold is standard, but we have seen bottom-of-page CTAs outperform in longer content. A/B test the placement to find what works for your audience.

2. Build trust before asking for information

According to research by Econsultancy, a physical address, contact phone number, and email address are the top three credibility signals for any website. But trust goes far beyond contact details.

Each level of trust reduces conversion friction further. Most sites stop at Level 1 or 2.

How to layer trust on your website:

• Display your phone number and email in the header, not buried in the footer.
• Add a well-designed contact page with a Google map, privacy policy, and a clear form.
• Show real client logos near the fold.
• Place review widgets from Google, Clutch, or Trustpilot where visitors can verify them.
• Include case studies with specific numbers, “increased leads by 35%” is more convincing than “great results”.

3. Add social proof near decision points

Social proof is one of the most powerful psychological drivers in marketing. When visitors see that others have trusted you, and got results, their resistance drops.

Where to place social proof for maximum impact:

• Near forms, a short testimonial quote above or beside the form.
• Near CTAs, “Trusted by 3,000+ clients” or a star rating badge.
• Throughout long pages, break up content with mini-testimonials and case study callouts every few scroll lengths. The key is specificity. “Great service!” is weak. “They built us a landing page that converted at 27.89%, nearly 6× the industry average” is powerful because it includes a verifiable number.

4. Optimise your forms for completion

Every extra field on your form costs you conversions. In our experience building 3,000+ landing pages, we see a consistent pattern: reducing form fields from 7 to 3-4 can lift conversion rates by 20-50%.

Form optimisation checklist:

• Only ask for information you genuinely need at this stage
• Use multi-step forms for longer applications. They feel less overwhelming
• Add inline validation so users fix errors in real time
• Make the submit button describe the outcome ("Get My Free Quote") not the action ("Submit")
• Add a privacy line below the form: "We respect your privacy. No spam."
• Pre-fill fields where possible (location, company name from IP/domain)

For complex lead generation, multi-step forms consistently outperform single-step forms. We used this approach for Affordable Health Coverage Today, building a custom landing page with auto-prefilled address fields using geotargeting, and the page converted at 20%.

5. Improve page speed

Slow pages kill conversions. Google’s own data shows that as page load time increases from 1 second to 3 seconds, bounce probability increases by 32%. At 5 seconds, it jumps to 90%.

Quick wins for page speed:

• Compress images to WebP format
• Lazy-load images below the fold
• Minimise render-blocking JavaScript
• Use a CDN (Cloudflare is free and effective)
• Aim for under 2.5 seconds Largest Contentful Paint (LCP) We have written a detailed guide on how to increase page speed for websites and landing pages if you want to go deeper.

6. Design for mobile first

Over 60% of web traffic now comes from mobile devices. If your forms are hard to fill, your buttons are too small to tap, or your page requires horizontal scrolling. You are losing leads.

Mobile conversion essentials:

• Buttons should be at least 48px × 48px (tap-friendly)
• Forms should use appropriate input types (tel for phone, email for email)
• Key content and CTA must be visible without scrolling
• Test on real devices, not just browser dev tools Learn more about building responsive landing pages that get results.

7. Write headlines that match search intent

Your headline has roughly 3 seconds to convince a visitor they are in the right place. If the headline does not match what they searched for, or what the ad promised, they bounce.

Headline principles:

• Match the keyword or ad copy the visitor clicked
• Lead with the benefit, not the feature
• Be specific: “Reduce Your CPL by 50%” beats “Better Marketing Results”
• Test headline variations. They are often the highest-impact element to A/B test

8. Optimise Above-the-Fold content

The area visitors see before scrolling (above the fold) determines whether they stay or leave. This section needs to answer three questions instantly:

1. What do you do? (Clear headline)
2. Why should I care? (Benefit-driven subheadline)
3. What should I do next? (Visible CTA) In our work with DOOR3, we redesigned their above-the-fold section with a sharper value proposition, clearer CTA, and prominent trust signals. The result: cost per lead dropped from $2,300 to $550.

9. Use dedicated landing pages for campaigns

Sending paid traffic to your homepage is one of the most common conversion killers. Homepages have multiple navigation options, competing CTAs, and no single focused message. A dedicated landing page strips away distractions and focuses entirely on one conversion goal. For Radicle Science, we built a dedicated clinical trial enrollment landing page that removed all navigation, focused on a single CTA, and used persona-matched copy. The result: a 51.78% conversion rate.

10. Drive the right traffic

Even a perfectly optimised website will not convert if the traffic is wrong. Low-quality traffic produces low conversion rates, no amount of CRO can fix a targeting problem.

Three traffic channels to prioritise:

11. A/b test everything: systematically

Opinions are cheap. Data is expensive. A/B testing lets you make conversion decisions based on evidence, not guesswork.

What to test (in priority order):

1. Headlines, the highest-impact element on most pages
2. CTA button, colour, copy, position, and size
3. Form length, fewer fields vs. More qualified leads
4. Social proof placement, near the CTA vs. In its own section
5. Page layout, single column vs. Two column, long vs. Short At Apexure, we use our EPIC framework to prioritise which tests to run first. EPIC stands for Experiment (learning potential), Priority (urgency), Impact (conversion potential), and Cost (resources needed). This prevents teams from wasting time on low-impact tests.

The EPIC framework makes sure you test what matters most. Learn how to apply it → Using this framework for a B2C agency client, we increased their conversion rate from 1.02% to 6.09%, a 500% improvement through systematic A/B testing. Read the full case study →

12. Monitor: analyse, and iterate

Conversion optimisation is not a one-time project. It is a continuous cycle of observing user behaviour, forming hypotheses, running tests, and implementing winners.

Our recommended monitoring stack:

We detail our full 13-step CRO process in a separate guide, it covers everything from heatmap analysis to hypothesis generation to statistical significance.

Real results: what CRO looks like in practice

These are not hypothetical numbers. Every metric below comes from a real Apexure client project:

For IMD Business School, we improved the conversion rate from 3.91% to 6.38% (a 63% lift) by optimising the placement of video testimonials and restructuring the above-the-fold section to better match the target MBA audience’s decision-making journey.

How Apexure approaches website conversion optimisation

We follow a structured, repeatable process for every CRO engagement:

This is the same process we have used for clients like Rocket Companies (4.5+ year engagement), DOOR3 (5+ years), and Headway, running multi-variant tests across dozens of landing pages.
