Traffic without conversion is cost without return. Every visitor who lands on your website and leaves without acting represents a gap between your marketing investment and your business outcome.

This guide provides a practical conversion rate optimisation checklist you can apply across your website, landing pages, and funnel stages.

Analytics and Tracking

Google Analytics 4 installed and verified with correct data collection

Conversion goals configured for every key action (form submissions, purchases, bookings)

Funnel exploration report set up in GA4 to track step-by-step drop-off

UTM parameters applied to all paid, email, and social traffic sources

Heatmap tool installed on high-priority pages (Hotjar or Microsoft Clarity)

Session recording enabled on key conversion pages

Google Search Console connected and verified

Core Web Vitals scores checked and benchmarked

Page Speed and Technical Performance

Largest Contentful Paint (LCP) under 2.5 seconds

Interaction to Next Paint (INP) under 200 milliseconds

Cumulative Layout Shift (CLS) score below 0.1

All images converted to WebP or AVIF format

Lazy loading applied to images below the fold

Explicit width and height attributes set on all images

Unused CSS and JavaScript removed or deferred

Third-party scripts audited and non-critical scripts loaded asynchronously

Hosting response time (TTFB) under 600 milliseconds

Mobile load time tested on a real device over 4G

Landing Page and Homepage

Headline is outcome-led and answers what the visitor gains

Subheadline provides one sentence of supporting context

Above-the-fold section contains: headline, subheadline, supporting visual, and primary CTA

Hero visual shows the product, outcome, or person (no generic stock imagery)

Message matches the traffic source that brings visitors to the page

Value proposition passes a five-second clarity test

Page has a single primary CTA with no competing links or navigation (on dedicated landing pages)

Social proof appears within the first scroll: logos, testimonials, or review scores

Page is free of jargon and uses second-person framing (“your,” “you”)

Mobile layout tested on 375px viewport with headline fully visible without scrolling

Calls to Action

Primary CTA uses specific, benefit-led copy (“Get My Free Audit” rather than “Submit”)

CTA button is visually dominant: highest contrast element on the page

CTA appears above the fold, after the key benefit section, and at the page end

No more than one primary CTA competes for attention at any point on the page

CTA copy reflects the specific offer on the page, matched to the visitor’s intent

CTA button size is minimum 48px height on mobile

Supporting micro-copy appears near the CTA to reduce friction (“Takes 2 minutes. No credit card required.”)

Forms and Checkout

Form asks only for fields needed at this stage of the relationship

Fields use clear visible labels, not placeholder text only

Form uses a single-column layout for mobile compatibility

Inline validation confirms correct input in real time

Form submission confirms what happens next (“We will be in touch within 24 hours”)

Privacy assurance appears near the submit button (one line is sufficient)

For e-commerce: guest checkout option is available

For e-commerce: all costs (shipping, taxes, fees) are visible before the final step

For e-commerce: multiple payment methods are supported

Progress indicator shown on multi-step forms or checkout flows

Form abandonment tracking is in place to identify which field causes exit

Trust and Social Proof

Client logos displayed on key conversion pages

Testimonials include full name, role, company, and a specific result

Case study data points are referenced near the primary CTA

Star ratings or review counts displayed where applicable

Security badges or certifications shown on transactional pages

Press mentions or third-party endorsements included where available

All proof is specific and quantified: numbers, timeframes, percentages

Trust signals are placed near CTAs and forms, not only at the bottom of the page

Testing and Iteration

A/B testing tool configured and integrated with your analytics platform

Test hypothesis written before any test begins (problem, change, expected outcome, success metric)

Tests run on one variable at a time

Minimum test duration set at two weeks or 95% statistical significance, whichever comes later

Test results logged with outcome and decision recorded

Monthly funnel review scheduled to track step conversion rates by channel

Quarterly review of session recordings and heatmaps on key conversion pages

High-traffic, low-converting pages identified and queued for next test cycle

Post-campaign funnel review conducted after each major traffic push

How to Use This Conversion Rate Optimisation Checklist

Work through each section in order. Start with analytics and tracking, because every other section depends on reliable data. Then address technical performance, as speed issues affect every page regardless of copy or design quality.

For each item you mark incomplete, estimate the traffic volume affected and the likely impact of fixing it. Prioritise the highest-volume, highest-impact gaps first.

Treat each fix as a test hypothesis rather than a definitive change. This keeps your programme structured and ensures improvements are validated before being treated as permanent.

Revisit the full checklist quarterly. Your website, traffic mix, and audience evolve. What is optimised today may require attention in six months.
