Search Health

This Base44 app injects title, meta, canonical, hreflang and JSON-LD client-side after React mounts. Google renders JavaScript, but crawlers that do not execute JS see an empty head. This cannot be marked PASS.

Redirects are client-side route replacements, not 301 responses. Link equity transfer is weaker than a server 301. Cleanest available fallback is implemented: canonical URL normalisation + client redirect + canonical tag on the destination.

Hero images come from the CMS at runtime, and the platform controls response caching headers, so a build-time <link rel="preload"> for the largest image and custom Cache-Control values are not available. Implemented instead: AVIF/WebP responsive delivery, eager + high fetch priority on hero images, lazy loading everywhere below the fold, and deferred third-party tags.

No server status code control, so removed articles cannot return 410. They are removed from the sitemap and return the 404 page instead.
