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:

## 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## 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](https://freeseoaudit.vercel.app) — paste your site and see. Free, stays free. Feedback very welcome,

especially on the GEO checks — useful or gimmick?
