Methodology and limits
Version 2026.10-2
What we read
Your homepage, robots.txt, sitemap, llms.txt and at most one product or room page. At most 10 requests, 30 seconds and 2 MB per page. We identify ourselves as ARCH-ReadinessCheck and read only public pages.
How it’s scored
Each check has a weight from 1 to 3. Verified earns full weight, Partially verified half, Not found none. Not verified and Not applicable are excluded. Product, price and booking checks apply only when we find a public store or booking path. An overall score is shown only when at least 60% of the applicable weight could be verified.
What it can’t tell you
It’s based on publicly verifiable website signals, not a complete assessment of agent capabilities. It doesn’t see real agent traffic or private agent conversations, signed-in checkout or booking flows, product feeds or marketplace listings. It reads one sample page, not your whole site, and doesn’t predict how any AI assistant ranks or recommends a business.
Safety
Only public domains on standard ports. Private, local and reserved network addresses are refused at validation and again at connection time. Redirects are re-checked, scans are rate-limited and results expire after 24 hours.
