I built a free SEO + AI-search (GEO) audit tool — no signup, no limits

I kept hitting the same wall: every SEO tool either paywalls the useful parts or caps you at a few pages. So I built a free one —
freeseoaudit.vercel.app. No signup, no crawl limit, open source.

## What it checks

Paste any URL and it streams a report across 40+ checks in 8 categories:

Metadata — titles, descriptions, canonicals, Open Graph
Structured data (JSON-LD) — validates schema against Google's rich-result rules
Crawl & indexing — robots.txt, sitemap, hreflang
Core Web Vitals and security headers
GEO / AEO — the part I care most about

## Why GEO/AEO?

Search is splitting in two. Classic SEO gets you blue-link rankings; GEO (Generative Engine Optimization) gets you cited
inside AI answers — ChatGPT, Perplexity, Google AI Overviews. The two now share under 20% of their winners.

So it checks things most SEO tools ignore:

llms.txt presence + spec conformance
Whether you're accidentally blocking GPTBot / ClaudeBot / PerplexityBot in robots.txt
The "Island Test" — are your paragraphs self-contained enough for an AI to lift as a citation?
Direct-answer detection and E-E-A-T signals

## Stack

Next.js 15 + React 19 on Vercel; Node + Express + TypeScript on Render. SSRF-hardened crawler, optional Playwright rendering,
results streamed over SSE. Runs entirely on free tiers.

## Try it

freeseoaudit.vercel.app — paste your site and see. Free, stays free. Feedback very welcome,
especially on the GEO checks — useful or gimmick?
