Measured on 2026-09-20 by asking the site 9 times — once as a browser, once as each of the 8 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. Tranco rank #1,007.
