Two of these columns matter differently. robots.txt is what the site declares. Live request is what actually happened when we sent a real request using that crawler's user agent from a datacentre IP, which is how edge blocking, rate limits and challenge pages show up even when robots.txt looks permissive.

✗

No <main> or <article> element marks the primary content

No <main> or <article> element, so extractors must guess where the content starts.

Why it matters. Boilerplate removers use `<main>` and `<article>` to decide which subtree is the content and which is navigation, promo, and footer. Without a landmark the extractor guesses by text density and often keeps the nav while dropping part of the body.
Fix. Wrap the page's unique content in exactly one `<main>` element, and use `<article>` for each self-contained item inside it. Put navigation in `<nav>`, site chrome in `<header>` and `<footer>`, and tangential blocks in `<aside>` so they are cleanly separable. Do not nest the content inside a `<div>` whose only meaning is a CSS class.

<body>
  <header><nav><!-- site navigation --></nav></header>
  <main>
    <article>
      <h1>How answer engines fetch your pages</h1>
      <p>Content that should be extracted and quoted.</p>
    </article>
  </main>
  <aside><!-- related links --></aside>
  <footer><!-- legal, contact --></footer>
</body>

No lang attribute declares the document language

No lang attribute on <html>.

Why it matters. `<html lang>` tells tokenizers and language filters which language the text is in. Without it a retrieval pipeline guesses, and a wrong guess drops the page from language-scoped candidate sets and degrades sentence splitting.
Fix. Set a valid BCP 47 tag on the root element, such as `lang="en"` or `lang="pt-BR"`. Mark inline passages in another language with `lang` on the containing element. If you publish translations, pair the declaration with `hreflang` alternates so each version is attributed to the right locale.

<html lang="en">
  <head>
    <link rel="alternate" hreflang="es" href="https://example.com/es/page" />
  </head>
</html>

Visible text is a small fraction of the HTML payload

Text is 5.6% of the 723 KB document; 59 KB is inline script.

Why it matters. Extractors strip scripts, styles, and wrapper markup before passing text to a model, and a page where content is a small fraction of the payload loses more of it to boilerplate removal. Inline JSON state blobs and deeply nested wrappers also push real text past the truncation limit of a retrieval context.
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.

✗

Structured data is too generic for what the page is about

No entity types that answer engines consume.

Why it matters. Answer engines route by entity type: a `Product` node supplies price and availability, an `Article` node supplies author and dates, and a `FAQPage` node supplies question and answer pairs. A generic `WebPage` or `WebSite` node on a product or article page carries none of those fields, so the specific facts stay unavailable.
Fix. Replace bare `WebPage` and `WebSite` nodes with the most specific type that describes the page, and fill the properties that type defines. Use `@graph` to publish several linked nodes on one page, such as an `Article` whose `publisher` points at an `Organization` node by `@id`. Add `BreadcrumbList` for hierarchy and reuse the same `@id` values across pages so the entity resolves to one record.

{
  "@context": "https://schema.org",
  "@graph": [
    {
      "@type": "Product",
      "@id": "https://example.com/products/widget#product",
      "name": "Widget Pro",
      "sku": "WGT-PRO-1",

✗

No machine-readable author is attached to the page

No author or Person entity, which weakens the authority signals answer engines use.

Why it matters. An `author` property in structured data is what lets an answer engine name a person or organisation as the source and link the byline to a stable profile. A byline that exists only as styled text is not reliably associated with the document during extraction.
Fix. Add an `author` property to the page's `Article`, `BlogPosting`, or `NewsArticle` node, typed as `Person` or `Organization`, with a `name` and a `url` pointing at a real profile page. Give each author a stable `@id` and reuse it across posts so the entity consolidates. Keep the visible byline identical to the structured value, and avoid generic names such as "Admin" or "Staff Writer" where a real author exists.

{
  "@context": "https://schema.org",
  "@type": "BlogPosting",
  "headline": "Allow AI answer engines in robots.txt",
  "author": {
    "@type": "Person",

    "name": "Dana Reyes",
    "url": "https://example.com/authors/dana-reyes",

    "sameAs": ["https://github.com/danareyes"]
  }

No machine-readable published or modified date

No publication or modification dates in structured data.

Why it matters. Answer engines prefer recent sources for questions about current state and use `dateModified` to decide whether a cached copy needs refetching. With no machine-readable date the page is treated as undated and loses to competitors that publish one.
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.

<time datetime="2026-08-04T14:20:00-04:00">Updated August 4, 2026</time>

No machine-readable license or usage terms for the content

No licence declaration, so reuse terms are ambiguous.

Why it matters. A `license` property, or a linked terms page, states the reuse conditions in a place a crawler can read, rather than leaving them to be inferred. Where terms are unstated, some pipelines default to the more restrictive handling, which reduces how much of the text is quoted.
Fix. Add a `license` property to the page's structured data pointing at a specific license URL, such as a Creative Commons deed or your own terms page, and add `rel="license"` on the visible link. Use `usageInfo` for conditions that are not a standard license, such as attribution wording or an API-only clause. State the terms once, at a stable URL, and reference it from every page rather than restating it per template.
