The 5 Elements Element Rule Example Headline 6 12 words, states the outcome "Ship docs in minutes, not days" Subheadline 15 25 words, expands on how "AI powered documentation that writes itself from your codebase. No templates needed." Hero image Shows the OUTCOME, not the product Person looking satisfied at results, not a screenshot of your UI Primary CTA Action verb + value "Start Free Trial" not "Submit" or "Learn More" Social proof Logos, count, or micro testimonial "Trusted by 10,000+ teams at [logos]" Headlines Formulas That Convert Formula Example [Outcome] without [pain] "Beautiful docs without the design skills" [Outcome] in [timeframe] "Launch your site in 5 minutes" The [better way] to [common task] "The faster way to build APIs" Stop [pain]. Start [outcome]. "Stop guessing. Start knowing." [Number] [things] to [outcome] "One tool to manage all your data" What Makes Headlines Fail Hero Images Show the Outcome, Not the Product CTA Buttons Text Good CTAs Bad CTAs "Start Free Trial" "Submit" "Get Started Free" "Click Here" "See It in Action" "Learn More" (low commitment) "Create Your First Report" "Sign Up" (vague) "Try Free for 14 Days" "Register" Formula: Action verb + value/outcome + (optional: reduce risk) Design Element Rule Color High contrast with background — must be the most visible element Size Minimum 44px height (tap target), wide enough for text + padding Position Above the fold, repeated after each major section Whitespace Generous padding around button, don't crowd it Secondary CTA If needed, use text link below ("or watch a demo") Section Order The proven sequence for landing pages: Section Purpose Key Element 1. Hero Core value, primary CTA Headline + image + CTA 2. Social Proof Build trust Logos, numbers, badges 3. Problem Create empathy Pain point they recognize 4. Solution/Features Show how you solve it 3 key features with visuals 5. How It Works Reduce complexity 3 steps: sign up, configure, benefit 6. Testimonials Prove it works 2 3 specific customer quotes 7. Pricing Enable decision Clear tiers, highlight recommended 8. FAQ Handle objections 5 7 common questions 9. Final CTA Capture remainders Repeat primary CTA with urgency Social Proof Types Type Impact Placement Company logos Fastest to process, high trust Below hero User count Scale signal Hero or social proof bar Star rating Product quality Near CTA Testimonials Detailed credibility Dedicated section Case study stats Specific proof Feature sections Trust badges Security/compliance Near forms, pricing, footer Form Design Rule Impact Every field reduces conversion ~11% Minimize fields Name + Email = maximum for signups Don't ask for phone, company, role Single column layout Don't use multi column forms Inline validation Show errors immediately, not on submit Clear error messages "Email is required" not "Error in field 3" Submit button text = action "Create Account" not "Submit" Mobile Optimization Rule Why CTA button full width Easy to tap with thumbs Sticky CTA on scroll Always accessible No horizontal scrolling Breaks mobile layout Font minimum 16px iOS zooms inputs below 16px Tap targets minimum 48x48px Apple HIG, Google Material Images responsive Don't overflow viewport Prioritize headline + CTA Simplify above the fold OG Image for Sharing Page Speed Rule Target Why Hero image < 200 KB First thing to load Total page weight < 2 MB Mobile data, patience Lazy load below fold Always Only load what's visible Minimize JavaScript < 200 KB Blocks rendering LCP (Largest Contentful Paint) < 2.5s Google Core Web Vitals Common Mistakes Mistake Problem Fix No clear headline Visitor doesn't know what you do 6 12 words, outcome focused CTA says "Learn More" Too low commitment Action verb + specific value Hero is a product screenshot Hard to parse, boring Show the outcome, use lifestyle imagery Multiple competing CTAs Decision paralysis One primary CTA, one secondary max No social proof No trust signal Add logos, counts, or testimonials Too many form fields Conversion drops ~11% per field Name + email maximum Desktop only design 60%+ traffic is mobile Design mobile first No urgency in final CTA Visitors leave and forget "Start your free 14 day trial" Related Skills Browse all apps: belt app list
