Blocks 1 of 24 answer engines, blocks 6 training crawlers, refuses AI user agents at the edge, publishes llms.txt.
Whether AI crawlers and answer-engine fetchers are permitted to request the page at all, in robots.txt, in robots directives, and at the edge.
Whether a fetcher that does not execute JavaScript receives the actual content, in markup an extractor can segment.
Machine-readable markup that states the page's type, entities, canonical URL, and discrete facts instead of leaving them to be inferred.
Signals that let an answer engine name the author, date the content, resolve the publisher, and cite it under known terms.

Reach 35.9 / 40
Edge returns 403, 429, or a challenge to AI user agents
Requests identifying as gptbot were refused at the edge (HTTP 403 Forbidden).
Fix. Fetch the page with each AI user agent string and compare the status and byte count against a browser request. On Cloudflare, check whether the "Block AI bots" toggle in AI Crawl Control, a Bot Fight Mode rule, or a WAF custom rule on `cf.verified_bot_category` is catching the request, then narrow it: block the training category and add a skip rule for the retrieval agents you want citing you. Verified bots must not be handed Managed Challenge, since a challenge is a hard failure for a non-browser client. Re-test after every WAF or bot-management change, because these toggles are applied zone-wide.

doneReferenceAnswer-engine fetchers are blocked, so you cannot be cited
Blocked from citing you: cohere-ai.
Fix. Separate the two crawler classes in robots.txt instead of blocking by vendor. Allow `OAI-SearchBot` and `ChatGPT-User` (OpenAI retrieval and user-initiated fetches), `Claude-SearchBot` and `Claude-User` (Anthropic retrieval), and `PerplexityBot` and `Perplexity-User`; keep any opt-out you want on `GPTBot`, `ClaudeBot`, `CCBot`, `Google-Extended`, and `Applebot-Extended`. Order does not decide precedence in RFC 9309 parsers, the longest matching rule does, so make the allow rules at least as specific as the disallow rules. Blocking retrieval buys nothing on training, because the training crawlers are separate user agents with separate rules.

Sitemap: https://example.com/sitemap.xmlReferenceTraining crawlers are disallowed for this path
Blocked by robots.txt: GPTBot, ClaudeBot, Google-Extended, Applebot-Extended, Meta-ExternalAgent, Amazonbot.
Fix. Decide this deliberately rather than by inheriting a template. If you want your content in model weights, remove the `Disallow: /` groups for `GPTBot`, `ClaudeBot`, `CCBot`, `Google-Extended`, and `Applebot-Extended`. If you do not, keep those groups but scope them to the paths that matter and leave retrieval fetchers untouched, because `Google-Extended` and `Applebot-Extended` only control training use and never affect search or answer citation. Record the decision somewhere durable so the next robots.txt edit does not silently reverse it.

Readability 20.6 / 25
Visible text is a small fraction of the HTML payload
Text is 2.3% of the 430 KB document; 285 KB is inline script.
Fix. Move inline hydration state and large inline scripts out of the document, or fetch them after load instead of embedding them. Flatten wrapper `div` trees and let semantic elements carry the content, and keep utility-class soup out of the article body. Serve the same text without the boilerplate at a stable URL if you need a clean extraction target.
Heading levels are missing, duplicated, or skipped
4 H1 and 49 headings total, 7 phrased as questions.
Fix. Give every page one `h1` that names its subject, then nest `h2` and `h3` without skipping levels. Make each heading describe the section beneath it in words a reader would search for, rather than a label like "Overview". Style with CSS instead of choosing heading levels for their font size, and never use a heading tag for a caption or a button.

Attribution 11 / 15
No machine-readable published or modified date
No publication or modification dates in structured data.
Fix. Publish `datePublished` and `dateModified` in the page's structured data as ISO 8601 values with a timezone offset. Update `dateModified` only when the content actually changes, since bumping it on every deploy trains crawlers to ignore it. Mirror the value in a visible `<time datetime>` element so the rendered text and the metadata agree, and keep the sitemap `lastmod` consistent with it.
