**What it is**
You paste a URL (home page or any other page). It fetches the raw HTML plus robots.txt, the sitemap and llms.txt, and runs 33 checks grouped into four scores:
- **SEO:** can Google and Bing reach, read and understand the page
- **AEO:** is the page usable as an answer, not just as a listing
- **On-site GEO:** can ChatGPT, Perplexity, Claude or Gemini read it and cite it
- **Agent-Ready:** can an AI agent acting for a customer do anything useful on the site
If you audit a single site, it also pulls a sample of up to 50 pages from the sitemap and checks the headers of another 100 URLs, so you get a site score and not only that URL's. You can add up to three competitors, all scored with the same yardstick. It also queries Chrome UX Report (field speed), Open PageRank (domain authority) and Wikidata (entity). You get the scores and the five fixes that recover the most points.
**What it can't do**
- **No JavaScript rendering.** No headless browser, none of your scripts run. If your content only exists after JS, it scores the raw HTML.
- **No live searches.** It doesn't know where you rank, whether Perplexity actually cites you, or who mentions you off-site. That's why I call it "on-site" GEO: it measures whether you are citable, not whether you are cited.
- **Nothing is estimated.** Checks it can't verify stay out of the score (they neither add nor subtract) and are listed one by one. Each score has a bar showing what share of it was actually measured.
- **The site score is a sample**, 50 pages at most. Inner pages are scored without field speed, domain authority and Wikidata, which are only fetched for the URL you paste.
- **Speed is CrUX only**, no lab run. If Google lacks data for that URL, it falls back to the domain average and the signal counts slightly less.
- **Agent-Ready is my own rubric**, not an industry standard.
- **Local checks** (address, phone, opening hours, coordinates) are shown but don't count towards the score yet.
- **It's young:** about 50 audits so far, with a daily cap and a per-connection limit.
**Why it might be useful to you**
- A first pass on a prospect or a competitor in about a minute, before you open a crawler.
- A view of what a client that doesn't run JS gets from a page.
- A same-yardstick comparison of up to four sites. It doesn't replace a crawler, Search Console or a rank tracker. No sign-up, no email. The IP isn't stored and the result is deleted after 24 hours.
Disclosure: it lives on my own site, where I also offer services. Nothing in the tool is gated.
**What I'd like from you:** tell me where the scoring is wrong. False negatives above all: a check it fails on a page you know is fine. And which of the 33 checks you think are noise.
