## English
### Description
- Comprehensive SEO analysis across all industries (SaaS, local services, e-commerce, publishers, agencies). Orchestrates specialized sub-skills and subagents, heavily emphasizing **Modern Web Performance** and **AI Search Readiness (GEO)**.
+ Comprehensive SEO audit covering technical SEO, on-page optimization, structured data, sitemaps, Core Web Vitals, E-E-A-T signals, and **Generative Engine Optimization (GEO)** for AI-powered search (Google AI Mode, ChatGPT Search, Perplexity).
### Trigger Conditions
- - Use when the user asks for a full SEO audit or broad SEO strategy.
- - Use as the umbrella entry point when multiple SEO dimensions are in scope.
- - Use when the task spans technical SEO, content, schema, sitemaps, and AI search readiness together.
+ - Running a full SEO audit on an existing web application.
+ - Optimizing technical SEO for a new Next.js / Astro site.
+ - Adding structured data (JSON-LD) for rich results and AI citation.
+ - Optimizing Core Web Vitals (LCP, INP, CLS).
+ - Preparing a site for Google AI Mode and ChatGPT Search indexing.
+ - Setting up a sitemap and `robots.txt`.
- ### Quick Reference Commands
- - `/seo audit <url>`: Full website audit with parallel subagent delegation.
- - `/seo page <url>`: Deep single-page analysis.
- - `/seo sitemap <url or generate>`: Analyze or generate XML sitemaps.
- - `/seo schema <url>`: Detect, validate, and generate Schema.org markup.
- - `/seo images <url>`: Image optimization analysis (WebP, lazy-load, alt-text).
- - `/seo technical <url>`: Technical SEO audit (Architecture, CWV, Crawlability).
- - `/seo content <url>`: E-E-A-T and content quality analysis.
- - `/seo geo <url>`: AI Overviews / Generative Engine Optimization.
- - `/seo plan <business-type>`: Strategic SEO planning.
+ ### 2026 SEO Landscape Changes
- ### Quality Gates & Modern Web Rules
- - **Thin Content**: WARNING at 30+ location pages (enforce 60%+ unique content).
- - **Schema Deprecations**: Never recommend HowTo schema (deprecated Sept 2023). FAQ schema only for government and healthcare sites.
- - **Core Web Vitals**: All performance references must use INP (Interaction to Next Paint), never FID. LCP must be < 2.5s.
- - **AI-First Indexing**: Always check for `llms.txt` readiness, semantic HTML tags, and clean text extraction for LLM crawlers.
- - **MPA Synergy**: When auditing a Multi-Page Application (orchestrated via `mpa-orchestrator`), ensure each server-rendered page delivers fully populated HTML and structured data on initial load without relying on client-side JavaScript execution.
+ | 2024 (Old) | 2026 (Current) |
+ |---|---|
+ | AI Overviews (SGE) | **Google AI Mode** — integrated AI answers |
+ | FID metric (deprecated) | **INP** (Interaction to Next Paint) |
+ | Keyword density focus | **Topical authority + E-E-A-T** |
+ | Backlinks only | **Citations in AI responses** |
+ | `robots.txt` only | `robots.txt` + **`/llms.txt`** |
- ### Scoring Methodology (SEO Health Score)
- Weighted aggregate of all categories:
- - **Technical SEO (20%)**: Crawlability, HTTPS, Architecture.
- - **Content Quality (E-E-A-T) (20%)**: Depth, Originality, Authoritativeness.
- - **On-Page SEO (15%)**: Title, Meta, Headers, Keywords.
- - **Performance (CWV) (15%)**: LCP, INP, CLS, Mobile-First.
- - **AI Search Readiness (GEO) (15%)**: Citability, llms.txt, Semantic HTML.
- - **Schema / Structured Data (10%)**: Rich Snippets Eligibility.
- - **Media & Images (5%)**: Alt-text, WebP, Lazy Loading.
+ ### Technical SEO Checklist
+ #### Core Web Vitals (2026 Targets)
+ ```
+ LCP (Largest Contentful Paint) < 2.5s
+ INP (Interaction to Next Paint) < 200ms ← replaced FID
+ CLS (Cumulative Layout Shift) < 0.1
+ TTFB (Time to First Byte) < 600ms
+ ```
+
+ **INP Optimization** (the new critical metric):
+ ```typescript
+ // INP is degraded by long tasks blocking the main thread
+ // Solution: Use React's useTransition to defer non-critical updates
+ import { useTransition } from 'react';
+
+ function SearchInput() {
+ const [isPending, startTransition] = useTransition();
+
+ const handleChange = (e: React.ChangeEvent<HTMLInputElement>) => {
+ startTransition(() => {
+ // Defer the expensive filtering to not block INP
+ setFilteredResults(filterData(e.target.value));
+ });
+ };
+ return <input onChange={handleChange} />;
+ }
+ ```
+
+ #### Crawlability & Indexing
+ ```typescript
+ // Next.js 15 — metadata API for complete SEO
+ // app/layout.tsx
+ export const metadata: Metadata = {
+ metadataBase: new URL('https://myapp.com'),
+ title: {
+ default: 'My SaaS — One-line value proposition',
+ template: '%s | My SaaS',
+ },
+ description: '150 characters max. Include primary keyword naturally.',
+ openGraph: {
+ type: 'website',
+ url: 'https://myapp.com',
+ siteName: 'My SaaS',
+ images: [{ url: '/og.png', width: 1200, height: 630 }],
+ },
+ twitter: { card: 'summary_large_image', creator: '@handle' },
+ robots: { index: true, follow: true },
+ alternates: { canonical: 'https://myapp.com' },
+ };
+ ```
+
+ ```typescript
+ // Dynamic sitemap.ts (Next.js App Router)
+ // app/sitemap.ts
+ import { MetadataRoute } from 'next';
+
+ export default async function sitemap(): Promise<MetadataRoute.Sitemap> {
+ const posts = await getBlogPosts();
+
+ return [
+ { url: 'https://myapp.com', lastModified: new Date(), changeFrequency: 'weekly', priority: 1 },
+ { url: 'https://myapp.com/features', lastModified: new Date(), changeFrequency: 'monthly', priority: 0.8 },
+ ...posts.map(p => ({
+ url: `https://myapp.com/blog/${p.slug}`,
+ lastModified: new Date(p.updatedAt),
+ changeFrequency: 'monthly' as const,
+ priority: 0.6,
+ })),
+ ];
+ }
+ ```
+
+ ### Structured Data (JSON-LD) for AI Citation
+ ```html
+ <!-- Organization schema — establishes brand entity -->
+ <script type="application/ld+json">
+ {
+ "@context": "https://schema.org",
+ "@type": "Organization",
+ "name": "My SaaS",
+ "url": "https://myapp.com",
+ "logo": "https://myapp.com/logo.png",
+ "sameAs": [
+ "https://twitter.com/myapp",
+ "https://linkedin.com/company/myapp"
+ ],
+ "contactPoint": {
+ "@type": "ContactPoint",
+ "contactType": "customer support",
+ "email": "support@myapp.com"
+ }
+ }
+ </script>
+
+ <!-- SoftwareApplication schema for SaaS products -->
+ <script type="application/ld+json">
+ {
+ "@context": "https://schema.org",
+ "@type": "SoftwareApplication",
+ "name": "My SaaS",
+ "applicationCategory": "BusinessApplication",
+ "operatingSystem": "Web",
+ "offers": {
+ "@type": "Offer",
+ "price": "0",
+ "priceCurrency": "USD",
+ "description": "Free tier available"
+ },
+ "aggregateRating": {
+ "@type": "AggregateRating",
+ "ratingValue": "4.8",
+ "reviewCount": "247"
+ }
+ }
+ </script>
+ ```
+
+ ### GEO — Google AI Mode Optimization
+ Google AI Mode (formerly AI Overviews) now powers the top of search results:
+ - **Be the source**: Write comprehensive, authoritative content on your core topics.
+ - **Q&A format**: Structure content as questions and answers — AI Mode quotes these directly.
+ - **Factual and specific**: Include statistics, named entities, and dates.
+ - **`/llms.txt`**: Add an AI-readable site index (see `seo-geo` skill).
+ - **Speed**: AI Mode favors fast-loading pages (TTFB < 600ms).
+
+ ### On-Page SEO Standards
+ ```
+ H1: One per page — primary keyword, compelling, < 60 chars
+ H2: Section headers — secondary keywords
+ H3: Sub-sections — long-tail keywords, FAQ answers
+ Meta Title: < 60 chars — keyword + brand
+ Meta Description: < 155 chars — keyword + CTA + benefit
+ URL: lowercase, hyphens, keyword-in-slug, < 5 segments
+ Images: Descriptive alt text, WebP format, lazy loading
+ Internal links: 3-5 per long-form page to related content
+ ```

+ - LCP < 2.5 detik
+ - **INP < 200ms** ← menggantikan FID
+ - CLS < 0.1
+ - TTFB < 600ms
+
+ **Optimasi INP**: Metrik kritis baru yang mengukur responsivitas interaksi. Gunakan `useTransition` React untuk menunda pembaruan non-kritis agar tidak memblokir thread utama.
+
+ #### Crawlability & Indexing
+ Gunakan Metadata API Next.js 15 untuk SEO lengkap: `title`, `description`, `openGraph`, `twitter`, `robots`, `alternates.canonical`. Buat sitemap dinamis dengan `app/sitemap.ts` yang menyertakan semua halaman statis dan konten dinamis.
+
+ ### Data Terstruktur (JSON-LD) untuk Kutipan AI
+ Tambahkan schema `Organization` untuk membangun entitas merek dan schema `SoftwareApplication` untuk produk SaaS — termasuk `aggregateRating` jika tersedia.
+
+ ### GEO — Optimasi Google AI Mode
+ Google AI Mode (sebelumnya AI Overviews) kini mendukung bagian atas hasil pencarian:
+ - Tulis konten yang komprehensif dan otoritatif tentang topik inti.
+ - Strukturkan konten sebagai Q&A — AI Mode langsung mengutip ini.
+ - Sertakan statistik, entitas bernama, dan tanggal.
+ - Tambahkan `/llms.txt` sebagai indeks situs yang dapat dibaca AI.
+ - Kecepatan: AI Mode lebih memilih halaman yang memuat cepat (TTFB < 600ms).
+
+ ### Standar SEO On-Page
+ H1 satu per halaman, H2 untuk header seksi, meta title < 60 karakter, meta deskripsi < 155 karakter, URL lowercase dengan tanda hubung dan keyword di slug, alt text deskriptif untuk semua gambar, 3-5 internal link per halaman long-form.
