The Problem

Google is shifting from "10 blue links" to AI-generated answers (AI Overviews). Perplexity, ChatGPT Search, and Google SGE are changing how people find information. But most indie makers and small teams don\'t have the resources to optimize for this new landscape.

The traditional SEO playbook — keyword stuffing, backlink farming — doesn\'t work for AI search engines. What matters now is structured data, entity clarity, and content that AI models can parse cleanly.

What I Built

AEO Auditor is a free one-click diagnostic tool that analyzes any webpage against 6 optimization dimensions specifically designed for AI search visibility:

Scoring Dimensions

Structured Data Detection — Identifies JSON-LD Schema types, flags missing required properties
Content Structure Analysis — H1/H2/H3 hierarchy validation
Readability Scoring — Language-aware thresholds (30 words for Chinese, 20 for English)
Entity Optimization — Organization, Author, BreadcrumbList with Schema-weighted scoring (2x priority)
Mobile Readiness — Viewport meta, responsive design checks
Social Metadata — og:title/description/image, Twitter Card validation

What Makes It Different

Every issue comes with a concrete fix — not just "add structured data," but the actual JSON-LD code you can copy-paste into your

{
  "@context": "https://schema.org",
  "@type": "WebApplication",
  "name": "Your App Name",
  "applicationCategory": "DeveloperApplication",
  "operatingSystem": "Web"
}

Tech Stack

Next.js 16 + TypeScript
Cheerio for server-side HTML parsing
Tailwind CSS v4 + shadcn/ui
Deployed on Vercel (free tier)
i18n with 228 translation keys (zh/en/es)

Page Type Auto-Detection

The analyzer classifies pages into 10 types (Homepage, Article, Product, FAQ, Service, etc.) by analyzing content signals, then applies different scoring weights per type.
