Can AI assistants read savills.co.uk?

Measured on 2026-09-19 by asking the site 7 times — once as a browser, once as each of the 6 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.

AWS CloudFront answers for this domain. Where a crawler above is refused while robots.txt allows it, the rule is applied by that edge, not written by the site — see how often each edge does this.

What to change, in order

  1. Let in the 4 crawlers your own robots.txt already allows+4 crawlers
    ClaudeBot, GPTBot, PerplexityBot, Meta-ExternalAgent are turned away before reading the page (served a bot challenge instead of the page), while robots.txt permits them — so this block is not written in your site. AWS CloudFront answers for this domain. AWS WAF Bot Control has an AI-crawler category that CloudFront enforces ahead of your origin. https://docs.aws.amazon.com/waf/latest/developerguide/waf-bot-control.html Fixing it takes this domain from 2 to 6 of 6 crawlers.
  2. Publish llms.txt
    llms.txt is 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.
  3. Mark the content with <main>
    The content-reachability check scores 11/100: with no <main> or <article> landmark, or with most of the page outside it, an assistant reads the navigation and the footer at the same cost as the text it came for.

savills.co.uk AI readability: C 65/100 
<a href="https://shop.lumnika.com/ai-readiness/savills.co.uk"><img src="https://shop.lumnika.com/ai-readiness/savills.co.uk/badge.svg" alt="AI readability"></a>
Method. 7 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.
