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 5.8% of HTML weight (14608/252256 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.

Martín was a free mulatto from Lagos , Portugal, who became a licensed pilot in Spain. He was contracted for Miguel López de Legazpi 's expedition from Mexico to the Philippines and was the pilot of a patache called the San Lucas . Martín and the San Lucas separated from the rest of the fleet and sailed through the Marshall Islands and the Caroline Islands before arriving at the Philippines. Without the rest of the fleet, Martín then embarked upon the return voyage from Asia to the Americas and arrived in Mexico. The Real Audiencia of Mexico ordered him to return to the Philippines and appear before Legazpi, who was expected to execute him for having deserted the rest of his fleet. Martín's ship, the San Jerónimo , departed Mexico and Martín led mutinies and took command of the ship. He anchored the San Jerónimo at Ujelang Atoll (pictured) in July 1566, where Martín and 26 other men were left behind and never seen again.

It is found in the Mediterranean Sea and adjacent Atlantic Ocean coasts, at depths from 3 to 40 metres (10 to 130 ft), and prefers shaded areas such as rock faces and crevices. During the breeding season, territorial males develop a characteristic yellow body with a black head, while females and other males are coloured grey-brown for camouflage. The black-faced blenny produces a red fluorescent signal using specialised cells in the iris, which it can regulate in brightness. Males defend nesting territories beneath overhangs, aggressively repelling intruders and defending the eggs from predators until they hatch. These black-faced blennies, one female and the other a territorial male, were photographed in Arrábida Natural Park , off the Portuguese coast.
