Can AI assistants read alltheweb.com?
Measured on 2026-09-19 by asking the site 5 times — once as a browser, once as each of the 4 crawlers that feed ChatGPT, Claude, Perplexity, Gemini, Meta AI, Apple Intelligence and Doubao — and comparing what came back. The AI-training opt-out tokens that never crawl are read from robots.txt instead.
F19 / 100
0 of 4 crawlers can read this page.
More readable than 0% of the 47,934 sites measured so far.
No JSON-LD.
What each crawler got back
| Crawler | HTTP | Result | robots.txt |
|---|---|---|---|
| ClaudeBot (Claude) | 500 | error | blocked |
| GPTBot (ChatGPT) | 500 | error | blocked |
| OAI-SearchBot (ChatGPT Search) | 500 | error | blocked |
| PerplexityBot (Perplexity) | 500 | error | blocked |
| Google-Extended (Gemini, AI Overviews) a robots.txt token, not a crawler: it controls how already-crawled pages may be used, and never makes a request of its own | — | opted out in robots.txt | blocked |
What to change, in order
- Declare the facts in JSON-LDThere is no JSON-LD on the page, so every fact — who you are, what you sell, the price — has to be guessed out of the prose and the layout. A schema.org block is the difference between being quoted correctly and being paraphrased.
- Publish sitemap.xml and llms.txtsitemap.xml and llms.txt are missing, so an assistant has to discover the site by following links. llms.txt is the emerging convention for telling an assistant which pages actually matter.
- Fix the plain structure: one <h1>, a title, a description, alt textThe structure check scores 40/100. These are the cheapest signals on the page and the first ones an assistant uses to decide what the site is.
- 4 crawlers are named and refused in robots.txt — a deliberate choiceClaudeBot, GPTBot, OAI-SearchBot, PerplexityBot are blocked by a rule that names them. Nothing to fix here: this page records what is true, not what should be. It is listed so the deliberate part of the block is not confused with the accidental part above.

Method. 5 live HTTP requests (one per crawler, one as a browser) plus robots.txt, llms.txt, sitemap.xml and security.txt, 12-second timeout each,
from a single vantage point. Blocking AI crawlers is a legitimate choice, not a failure: this page records what is true, not what should be.
Domain comes from a shop-platform seed (Shopify/WooCommerce/Magento/BigCommerce/Shopline fingerprint or JSON-LD price), not the Tranco traffic ranking. One page per domain — the homepage — is audited.
