Design high-converting landing pages with AI-generated visuals via inference.sh CLI.
Quick Start
curl -fsSL https://cli.inference.sh | sh && infsh login
Generate a hero image
infsh app run falai/flux-dev-lora --input '{ "prompt": "professional person smiling while using a laptop showing a clean dashboard interface, bright modern office, natural lighting, warm and productive atmosphere, lifestyle marketing photography", "width": 1248, "height": 832 }'
Research competitor landing pages
infsh app run tavily/search-assistant --input '{ "query": "best SaaS landing page examples 2024 conversion rate" }'
Above-the-Fold Formula
Everything visible before scrolling must communicate value in 5 seconds.
┌─────────────────────────────────────────────────┐ │ [Logo] [Nav] [CTA Button] │ │ │ │ Headline (6-12 words) │ │ ───────────────────────── │ │ Subheadline (15-25 words) [Hero Image] │ │ showing the │ │ [Primary CTA Button] OUTCOME, not │ │ "Start Free Trial" the product │ │ │ │ Social proof: "Trusted by 10,000+ teams" │ │ [logo] [logo] [logo] [logo] [logo] │ └─────────────────────────────────────────────────┘
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
infsh 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
infsh 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
-
Hero Core value, primary CTA Headline + image + CTA
-
Social Proof Build trust Logos, numbers, badges
-
Problem Create empathy Pain point they recognize
-
Solution/Features Show how you solve it 3 key features with visuals
-
How It Works Reduce complexity 3 steps: sign up, configure, benefit
-
Testimonials Prove it works 2-3 specific customer quotes
-
Pricing Enable decision Clear tiers, highlight recommended
-
FAQ Handle objections 5-7 common questions
-
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
infsh 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
infsh 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
infsh 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"
