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>"
