Description

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

• 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.

2026 SEO Landscape Changes

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):

// 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

// 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' },
};

// 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

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Organization",
  "name": "My SaaS",
  "url": "https://myapp.com",

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.
• AEO Extraction Sentence: Write one 25–40 word sentence that answers "What is [product]?" immediately after the H1. This is the sentence AI engines extract.
• Factual and specific: Include statistics, named entities, and dates.
• Speed: AI Mode favors fast-loading pages (TTFB < 600ms).

The 2026 AI Search Landscape

/llms.txt — AI Indexing Protocol

Add an /llms.txt file at your domain root:

# /llms.txt
# AI-friendly site map for LLM indexers
## Product
- [Features](/features): Complete feature list with pricing
## Content
- [Blog](/blog): Technical articles

Landing Page SEO/AEO Narrative Arc

Follow this exact order for landing pages:

1. Hero — H1 + AEO sentence + CTA
2. Problem — Audience pain, no product mention yet
3. Solution — Introduce product as the answer
4. Features as Benefits — Table format
5. Social Proof & FAQ (under 50 words each)

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

Perubahan Lanskap SEO 2026

Checklist SEO Teknikal

Core Web Vitals (Target 2026)

• 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 AI Mode & Landing Page AEO

Google AI Mode (sebelumnya AI Overviews) dan Perplexity sangat menyukai format berikut:

• Kalimat Ekstraksi AEO: Buat satu kalimat ringkas 25–40 kata ("Apa itu [produk]?") di blockquote setelah H1.
• Tulis konten Q&A dan sertakan statistik spesifik.
• Alur Narasi Landing Page: Hero (H1+AEO) -> Problem -> Solution -> Features -> Social Proof -> FAQ (tiap jawaban <50 kata).
• Tambahkan /llms.txt sebagai indeks situs yang dapat dibaca AI.
• Kecepatan: Halaman harus memuat sangat 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.
