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
❌ "Welcome to Our Platform" (says nothing about value)
❌ "The World's Most Advanced AI-Powered Solution" (buzzwords, no specifics)
❌ "We Help Businesses Grow" (vague, generic)
❌ "Next-Generation Enterprise Software" (what does it DO?)
✅ "Turn customer feedback into product features, automatically"
✅ "The spreadsheet that thinks like a database"
✅ "Find and fix bugs before your users do"
Hero Images
Show the Outcome, Not the Product
❌ Screenshot of your dashboard (boring, hard to parse at a glance)
❌ Abstract geometric background (says nothing)
❌ Stock photo of a handshake (cliché)
✅ Person looking satisfied at clear results on their screen
✅ Before/after transformation
✅ The end result of using your product
# Outcome-focused hero
belt app run falai/flux-dev-lora --input '{
"prompt": "happy professional team celebrating around a laptop showing positive growth charts, bright modern office, natural sunlight, authentic candid moment, marketing photography style, warm tones",
"width": 1248,
"height": 832
}'
# Product-in-context hero
belt app run bytedance/seedream-4-5 --input '{
"prompt": "clean modern laptop on a minimalist desk showing a beautiful analytics dashboard, floating UI elements emerging from the screen, soft gradient background, product marketing style, professional",
"size": "2K"
}'
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 |
# Research for social proof stats
belt app run exa/answer --input '{
"question": "What is the average conversion rate for SaaS landing pages with social proof vs without?"
}'
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
# Generate an OG image for the landing page
belt app run falai/flux-dev-lora --input '{
"prompt": "clean professional social sharing card, product name and tagline on modern gradient background, minimal design, corporate tech aesthetic, 1200x630 aspect ratio equivalent",
"width": 1200,
"height": 630
}'
# Or use html-to-image for a template-based approach
belt app run infsh/html-to-image --input '{
"html": "<div style=\"width:1200px;height:630px;background:linear-gradient(135deg,#667eea,#764ba2);display:flex;align-items:center;justify-content:center;font-family:sans-serif;color:white\"><div style=\"text-align:center\"><h1 style=\"font-size:48px;margin:0\">DataFlow</h1><p style=\"font-size:24px;opacity:0.9\">Ship docs in minutes, not days</p></div></div>"
}'
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" |
