The High-Converting Website Checklist: 30 Points Every Business Website Must Pass

A website that looks professional but fails these 30 checks is losing leads every day. Use this checklist to audit your own site, brief a developer, or review a build before launch. Each point is based on what consistently separates high-converting business websites from underperforming ones.

Section 1: Value Proposition and Messaging (Homepage)

• [ ] 1. Specific headline within 5 seconds — Can a first-time visitor understand what you do, who you serve, and why you're different in 5 seconds? "IT Support for UK Manufacturing Businesses" beats "Expert IT Solutions."

• [ ] 2. Clear subheadline — The headline makes the claim; the subheadline supports it with a specific benefit or differentiator.

• [ ] 3. Primary CTA visible without scrolling — Your main CTA (Book, Get Quote, Start Free Trial) appears above the fold on both desktop and mobile.

• [ ] 4. CTA is specific, not generic — "Book a Free 30-Minute Consultation" converts better than "Contact Us." Specific offers reduce friction.

• [ ] 5. Customer language, not company language — Headlines speak to the customer's problem ("Tired of losing leads?") not to your company story ("We've been in business since 2010").

Section 2: Trust and Social Proof

• [ ] 6. Trust signals above the fold — At least one trust signal visible without scrolling: client logos, review badge (★★★★★), accreditation, "as seen in" press, or specific customer count.

• [ ] 7. Named testimonials with results — "Great service!" is weak. "We saved 15 hours a week and our support tickets dropped by 60% — Sarah M., Operations Director at Acme Ltd" is powerful.

• [ ] 8. Case studies or results data — Numbers build credibility. Specific outcomes ("£1,840/month in recovered cart revenue") outperform vague claims ("significant results").

• [ ] 9. Team/founder visibility — B2B and service businesses: customers buy from people. A photo and bio for the founder or key team members increases trust.

• [ ] 10. Credentials and accreditations displayed — Industry certifications, partnerships (Google Partner, Shopify Expert), and relevant memberships visible on relevant pages.

Section 3: Lead Capture and CTAs

• [ ] 11. Multiple lead capture points — Not just a Contact page. Inline forms on service pages, homepage CTA, exit-intent popup, sticky nav CTA for important pages.

• [ ] 12. Contact form is simple — Maximum 4 fields for initial contact. More fields = fewer submissions. Name, email, phone, message is enough.

• [ ] 13. Phone number visible in header — For service businesses, a visible phone number in the header increases trust and provides a direct conversion path.

• [ ] 14. WhatsApp or live chat available — For UK businesses, WhatsApp chat on the website captures visitors who prefer messaging to forms.

• [ ] 15. Lead magnet offered — A valuable free resource (checklist, guide, calculator, audit) in exchange for email address. Extends lead capture beyond "ready to buy now" visitors.

Section 4: Service and Product Pages

• [ ] 16. Each service page addresses the customer's problem — Not just what you offer, but the problem it solves and the outcome the customer gets.

• [ ] 17. Pricing or pricing range provided — Hiding prices increases friction and attracts unqualified enquiries. Even "from £500/month" sets expectations and qualifies prospects.

• [ ] 18. Process explained — "Here's how working with us works:" reduces the fear of the unknown and makes taking the next step feel safe.

• [ ] 19. Each service page ends with a specific CTA — Not "contact us for more information" — a specific next step relevant to that service.

• [ ] 20. Internal linking between related content — Related service pages, blog posts, and case studies linked within service pages improve SEO and time on site.

Section 5: Performance and Technical

• [ ] 21. Mobile load time under 2.5 seconds — Test with PageSpeed Insights. LCP under 2.5s is the Google Core Web Vitals pass threshold.

• [ ] 22. Passes Core Web Vitals — LCP < 2.5s, CLS < 0.1, INP < 200ms. Use PageSpeed Insights or Chrome User Experience Report.

• [ ] 23. Images optimised and in next-gen format — All images served as WebP or AVIF, appropriately sized for display dimensions, with lazy loading enabled.

• [ ] 24. No render-blocking scripts — Third-party scripts (analytics, chat, ads) should load asynchronously and not block initial page render.

• [ ] 25. HTTPS on all pages — A padlock in the browser bar. Non-HTTPS sites trigger browser security warnings and rank lower in Google.

Section 6: SEO Fundamentals

• [ ] 26. Unique title tag on every page — 50–60 characters, includes primary keyword, specific to that page's content.

• [ ] 27. Meta description on every page — 150–160 characters, includes a CTA, accurately describes the page content.

• [ ] 28. H1 on every page — One H1 per page, containing the primary keyword, matching the topic of the page.

• [ ] 29. Google Analytics + Search Console configured — With conversion goals set up in GA4 (form submissions, phone click, booking completions). Without this, you're flying blind.

Section 7: Compliance (UK Businesses)

• [ ] 30. GDPR cookie consent implemented — UK ICO-compliant cookie banner with genuine consent options (accept/reject/customise). Google Analytics should only fire after consent. Privacy policy and cookie policy linked and up to date.

How to Use This Checklist

Score your website against each point. 27–30 passes: your website is well-optimised. 20–26 passes: good foundations, specific improvements will meaningfully increase leads. Under 20 passes: significant conversion opportunity being missed.

Frequently Asked Questions

Should I score every page or just the homepage?

Score the homepage first — it gets the most traffic and sets the tone. Then audit your top 3 service pages (highest traffic, highest intent). These pages collectively account for 70–80% of your conversion opportunity.

What's the fastest checklist improvement for most sites?

Items 3 (CTA visible without scrolling), 6 (trust signals above the fold), and 4 (specific CTA text) are typically fixable in under a day and consistently produce immediate conversion improvements.

How often should I re-run this checklist?

After every major content or design update, and at minimum once per quarter. Search engine requirements evolve (Core Web Vitals thresholds change), and your conversion messaging should evolve as your business and market change.
