No reachable sitemap.xml. Publish one and reference it in robots.txt.

Fix: Publish /sitemap.xml and reference it from robots.txt with a Sitemap: line.

No <meta name="description">. Agents use it as a page summary; add a 50–200 character description.

Fix: Add `<meta name="description" content="...">` to your primary pages. Agents frequently use it as a summary.

Found /llms.txt but missing H1 header and markdown links.

Fix: Publish /llms.txt at your domain root. Build a spec-compliant one at /tools/llms-txt-generator.

No HTTP Link: response headers. Emit canonical/alternate/describedby relations so HEAD-only or stream-rendering agents get them without parsing HTML.

Fix: Emit `Link:` headers for canonical, alternate-language, and describedby relations. Agents that fetch HEAD-only or stream-render rely on these.

Visible text is 6.1% of HTML weight (15732/255963 bytes). Low. Markup may be crowding out agent-usable text.

Fix: Heavy ad or navigation markup crowds out agent-usable text. Aim for a text-to-DOM ratio above 15%.

1 recommended-field warning(s). First: Article recommends "description" (improves agent comprehension).

Fix: Validate your JSON-LD with Google Rich Results test. Fix missing required properties.

It is a long-distance migrant , breeding in the Siberian Arctic from June to August or September before migrating south to winter on the coasts of southern Afro-Eurasia . Adults have two main plumages: the non-breeding plumage shows brown-greyish upperparts and white underparts, while the breeding plumage is much more striking, with the entire front tinted a deep rusty colour , more intensely so in males. Its courtship behaviour is complex and involves several distinct displays. The female almost always lays one clutch of eggs, usually around the end of June; the eggs hatch after 20 days, and the chicks, relatively mature and mobile at birth , fully fledge at 14 to 20 days. The curlew sandpiper's breeding success is linked to lemming populations: in years when lemmings are abundant, predators hunt them instead. It is omnivorous , foraging in wetlands in large flocks for various invertebrates , including crabs and insects.

Commander Neil Armstrong and Lunar Module Pilot Buzz Aldrin set the Apollo Lunar Module Eagle down on July 20, 1969, with Armstrong and Aldrin stepping onto the lunar surface six hours later. They spent about two and a quarter hours together outside the spacecraft, and collected 47.5 pounds (21.5 kg) of lunar material. While they were on the Moon's surface, Michael Collins flew the command module Columbia alone in lunar orbit.
