5. Social Proof - Reviews, ratings, user statistics
6. Images or Videos - Visual demonstration of product/service
7. Core Benefits/Features - 3-6 key advantages with icons
8. Customer Testimonials - 4-6 authentic reviews with photos
9. FAQ Section - 5-10 common questions with accordion UI
10. Final CTA - Bottom call-to-action for second chance conversion
11. Contact Information/Legal Pages - Footer with complete information

Critical: All 11 elements must be included in every landing page. No exceptions.

│   ├── page.tsx            # Main landing page
│   └── globals.css         # Global styles
├── components/
│   ├── Header.tsx          # Logo & Navigation (Element 2)
│   ├── Hero.tsx            # Title, CTA, Social Proof (Elements 3-5)

Implementation Workflow

Step 1: Setup Metadata (SEO)

Always start with proper SEO metadata in layout.tsx or page.tsx:

import type { Metadata } from 'next'

export const metadata: Metadata = {
  title: 'SEO Optimized Title with Keywords | Brand Name',
  description: 'Compelling description with main keywords',
  keywords: ['keyword1', 'keyword2', 'keyword3'],
  openGraph: {
    title: 'OG Title',
    description: 'OG Description',
    images: ['/og-image.jpg'],
  },
}

Step 2: Create Component Structure

Build components in this order to ensure proper flow:

1. Header with logo (Element 2)
2. Hero section with title, subtitle, primary CTA, and social proof (Elements 3-5)
3. MediaSection with product images/videos (Element 6)
4. Benefits section with 3-6 feature cards (Element 7)
5. Testimonials with customer reviews (Element 8)
6. FAQ with accordion (Element 9)
7. FinalCTA at bottom (Element 10)
8. Footer with contact and legal links (Element 11)

Step 3: Use ShadCN UI Components

Map each section to appropriate ShadCN components:

• Hero CTA: Use Button component with size="lg"
• Benefits: Use Card, CardHeader, CardTitle, CardContent
• Testimonials: Use Card, Avatar, Badge
• FAQ: Use Accordion, AccordionItem, AccordionTrigger, AccordionContent
• Final CTA: Use Button and Card
• Footer: Use Separator, Input for newsletter

Step 4: Implement Responsive Design

Ensure mobile-first responsive design:

• Use Tailwind responsive prefixes: sm:, md:, lg:, xl:
• Test all breakpoints: 640px (sm), 768px (md), 1024px (lg), 1280px (xl)
• Minimum touch target size: 44x44px for buttons
• Base font size: minimum 16px on mobile

Step 5: Optimize Performance

• Use Next.js Image component for all images
• Add priority prop to above-the-fold images
• Implement lazy loading for below-the-fold content
• Use dynamic imports for heavy components if needed

Step 6: Ensure Accessibility

• Use semantic HTML5 elements (<header>, <main>, <section>, <footer>)
• Add ARIA labels where needed
• Ensure keyboard navigation works
• Provide alt text for all images
• Maintain sufficient color contrast (WCAG AA minimum)
