Method. Six live HTTP requests plus robots.txt, llms.txt, sitemap.xml and security.txt, 12-second timeout each,

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.
