# Landing Page Generator

Generate high-converting landing pages from a product description. Output complete Next.js/React components with multiple section variants, proven copy frameworks, SEO optimization, and performance-first patterns. Not lorem ipsum — actual copy that converts.

**Target:** LCP < 1s · CLS < 0.1 · FID < 100ms  
**Output:** TSX components + Tailwind styles + SEO meta + copy variants

## When to Use

- You need to generate a marketing landing page in Next.js or React.
- The task involves conversion-focused page structure, section variants, Tailwind styling, or SEO-aware copy.
- You want complete landing-page output from a product description rather than isolated UI fragments.

## Core Capabilities

- 5 hero section variants (centered, split, gradient, video-bg, minimal)
- Feature sections (grid, alternating, cards with icons)
- Pricing tables (2–4 tiers with feature lists and toggle)
- FAQ accordion with schema markup
- Testimonials (grid, carousel, single-quote)
- CTA sections (banner, full-page, inline)
- Footer (simple, mega, minimal)
- 4 design styles with Tailwind class sets

---

## Generation Workflow

Follow these steps in order for every landing page request:

1. **Gather inputs** — collect product name, tagline, audience, pain point, key benefit, pricing tiers, design style, and copy framework using the trigger format below. Ask only for missing fields.
2. **Analyze brand voice** (recommended) — if the user has existing brand content (website copy, blog posts, marketing materials), run it through `marketing-skill/content-production/scripts/brand_voice_analyzer.py` to get a voice profile (formality, tone, perspective). Use the profile to inform design style and copy framework selection:
   - formal + professional → **enterprise** style, **AIDA** framework
   - casual + friendly → **bold-startup** style, **BAB** framework
   - professional + authoritative → **dark-saas** style, **PAS** framework
   - casual + conversational → **clean-minimal** style, **BAB** framework
3. **Select design style** — map the user's choice (or infer from brand voice analysis) to one of the four Tailwind class sets in the Design Style Reference.
4. **Apply copy framework** — write all headline and body copy using the chosen framework (PAS / AIDA / BAB) before generating components. Match the voice profile's formality and tone throughout.
5. **Generate sections in order** — Hero → Features → Pricing → FAQ → Testimonials → CTA → Footer. Skip sections not relevant to the product.
6. **Validate against SEO checklist** — run through every item in the SEO Checklist before outputting final code. Fix any gaps inline.
7. **Output final components** — deliver complete, copy-paste-ready TSX files with all Tailwind classes, SEO meta, and structured data included.

## Triggering This Skill

```
Product: [name]
Tagline: [one sentence value prop]
Target audience: [who they are]
Key pain point: [what problem you solve]
Key benefit: [primary outcome]
Pricing tiers: [free/pro/enterprise or describe]
Design style: dark-saas | clean-minimal | bold-startup | enterprise
Copy framework: PAS | AIDA | BAB
```

---

## Design Style Reference

| Style | Background | Accent | Cards | CTA Button |
|---|---|---|---|---|
| **Dark SaaS** | `bg-gray-950 text-white` | `violet-500/400` | `bg-gray-900 border border-gray-800` | `bg-violet-600 hover:bg-violet-500` |
| **Clean Minimal** | `bg-white text-gray-900` | `blue-600` | `bg-gray-50 border border-gray-200 rounded-2xl` | `bg-blue-600 hover:bg-blue-700` |
| **Bold Startup** | `bg-white text-gray-900` | `orange-500` | `shadow-xl rounded-3xl` | `bg-orange-500 hover:bg-orange-600 text-white` |
| **Enterprise** | `bg-slate-50 text-slate-900` | `slate-700` | `bg-white border border-slate-200 shadow-sm` | `bg-slate-900 hover:bg-slate-800 text-white` |

> **Bold Startup** headings: add `font-black tracking-tight` to all `<h1>`/`<h2>` elements.

---

## Copy Frameworks

**PAS (Problem → Agitate → Solution)**
- H1: Painful state they're in
- Sub: What happens if they don't fix it
- CTA: What you offer
- *Example — H1:* "Your team wastes 3 hours a day on manual reporting" / *Sub:* "Every hour spent on spreadsheets is an hour not closing deals. Your competitors are already automated." / *CTA:* "Automate your reports in 10 minutes →"

**AIDA (Attention → Interest → Desire → Action)**
- H1: Bold attention-grabbing statement → Sub: Interesting fact or benefit → Features: Desire-building proof points → CTA: Clear action

**BAB (Before → After → Bridge)**
- H1: "[Before state] → [After state]" → Sub: "Here's how [product] bridges the gap" → Features: How it works (the bridge)

## Representative Component: Hero (Centered Gradient — Dark SaaS)

Use this as the structural template for all hero variants. Swap layout classes, gradient direction, and image placement for split, video-bg, and minimal variants.

```tsx
export function HeroCentered() {
  return (
    <section className="relative flex min-h-screen flex-col items-center justify-center overflow-hidden bg-gray-950 px-4 text-center">
      <div className="absolute inset-0 bg-gradient-to-b from-violet-900/20 to-transparent" />
      <div className="pointer-events-none absolute -top-40 left-1/2 h-[600px] w-[600px] -translate-x-1/2 rounded-full bg-violet-600/20 blur-3xl" />
      <div className="relative z-10 max-w-4xl">
        <div className="mb-6 inline-flex items-center gap-2 rounded-full border border-violet-500/30 bg-violet-500/10 px-4 py-1.5 text-sm text-violet-300">
          <span className="h-1.5 w-1.5 rounded-full bg-violet-400" />
          Now in public beta
        </div>
        <h1 className="mb-6 text-5xl font-bold tracking-tight text-white md:text-7xl">
          Ship faster.<br />
          <span className="bg-gradient-to-r from-violet-400 to-pink-400 bg-clip-text text-transparent">
            Break less.
          </span>
        </h1>
        <p className="mx-auto mb-10 max-w-2xl text-xl text-gray-400">
          The deployment platform that catches errors before your users do.
          Zero config. Instant rollbacks. Real-time monitoring.
        </p>
        <div className="flex flex-col items-center gap-4 sm:flex-row sm:justify-center">
          <Button size="lg" className="bg-violet-600 text-white hover:bg-violet-500 px-8">
            Start free trial
          </Button>
          <Button size="lg" variant="outline" className="border-gray-700 text-gray-300">
            See how it works →
          </Button>
        </div>
        <p className="mt-4 text-sm text-gray-500">No credit card required · 14-day free trial</p>
      </div>
    </section>
  )
}
```

## Other Section Patterns

### Feature Section (Alternating)

Map over a `features` array with `{ title, description, image, badge }`. Toggle layout direction with `i % 2 === 1 ? "lg:flex-row-reverse" : ""`. Use `<Image>` with explicit `width`/`height` and `rounded-2xl shadow-xl`. Wrap in `<section className="py-24">` with `max-w-6xl` container.

### Pricing Table

Map over a `plans` array with `{ name, price, description, features[], cta, highlighted }`. Highlighted plan gets `border-2 border-violet-500 bg-violet-950/50 ring-4 ring-violet-500/20`; others get `border border-gray-800 bg-gray-900`. Render `null` price as "Custom". Use `<Check>` icon per feature row. Layout: `grid gap-8 lg:grid-cols-3`.

### FAQ with Schema Markup

Inject `FAQPage` JSON-LD via `<script type="application/ld+json" dangerouslySetInnerHTML={{ __html: JSON.stringify(schema) }} />` inside the section. Map FAQs with `{ q, a }` into shadcn `<Accordion>` with `type="single" collapsible`. Container: `max-w-3xl`.

### Testimonials, CTA, Footer

- **Testimonials:** Grid (`grid-cols-1 md:grid-cols-3`) or single-quote hero block with avatar, name, role, and quote text.
- **CTA Banner:** Full-width section with headline, subhead, and two buttons (primary + ghost). Add trust signals (money-back guarantee, logo strip) immediately below.
- **Footer:** Logo + nav columns + social links + legal. Use `border-t border-gray-800` separator.

## SEO Checklist

- [ ] `<title>` tag: primary keyword + brand (50–60 chars)
- [ ] Meta description: benefit + CTA (150–160 chars)
- [ ] OG image: 1200×630px with product name and tagline
- [ ] H1: one per page, includes primary keyword
- [ ] Structured data: FAQPage, Product, or Organization schema
- [ ] Canonical URL set
- [ ] Image alt text on all `<Image>` components
- [ ] robots.txt and sitemap.xml configured
- [ ] Core Web Vitals: LCP < 1s, CLS < 0.1
- [ ] Mobile viewport meta tag present
- [ ] Internal linking to pricing and docs

> **Validation step:** Before outputting final code, verify every checklist item above is satisfied. Fix any gaps inline — do not skip items.

---

## Performance Targets

| Metric | Target | Technique |
|---|---|---|
| LCP | < 1s | Preload hero image, use `priority` on Next/Image |
| CLS | < 0.1 | Set explicit width/height on all images |
| FID/INP | < 100ms | Defer non-critical JS, use `loading="lazy"` |
| TTFB | < 200ms | Use ISR or static generation for landing pages |
| Bundle | < 100KB JS | Audit with `@next/bundle-analyzer` |

---

## Common Pitfalls

- Hero image not preloaded — add `priority` prop to first `<Image>`
- Missing mobile breakpoints — always design mobile-first with `sm:` prefixes
- CTA copy too vague — "Get started" beats "Learn more"; "Start free trial" beats "Sign up"
- Pricing page missing trust signals — add money-back guarantee and testimonials near CTA
- No above-the-fold CTA on mobile — ensure button is visible without scrolling on 375px viewport
