Card metadata describes a sharing preview format. Detecting a tag does not verify the preview shown by a platform.
Keep in mind
Review the card type, title, description and image together, allowing for platform caching.

0 JSON-LD blocks · 0 types
At least one JSON-LD block with @type and no unreadable blocks
JSON-LD describes entities and relationships in a machine-readable form. Parsing JSON is separate from validating required search feature properties.
Recommended action
Match markup to visible content and validate it with a rich result testing tool. Eligibility does not guarantee display.

Response HTML <head> / script[type=application/ld+json]
Use the example JSON in an application/ld+json script only when it matches the page. Fix existing JSON syntax first and validate any rich-result requirements separately.

This detects WebP/AVIF from img src/srcset extensions and picture source types. Images whose format cannot be inferred from HTML, such as extensionless CDN URLs, may not be reflected in the count.
Recommended action
Compare quality and file size, and inspect the actual delivered format in browser developer tools.

Convert this file to WebP/AVIF and use the actual converted URL. Do not merely rename its extension. Keep it if the CDN already serves a modern format.

Lazy loading
Needs review
0/5
This detects loading="lazy" on img elements. Pages with few images can pass the tool’s heuristic without it.
HTML response line 151 · /html/body/div[3]/div[1]/header/h1/a/img
Add loading="lazy" only if this image is below the initial viewport. Keep prominent initial-viewport images eager.

AI search/answer bots allowed 0/5 · training bots allowed 0/3
Passes when every AI search/answer bot is allowed; training bots are shown for reference only
This interprets root-path robots.txt rules for five AI search/answer bots (which read pages to cite them in answers) and three training bots. Only the search/answer bots decide the result; training bots are shown for reference. Actual citations are not checked.
Recommended action
Allow the search/answer bots if you want to be cited in AI answers. Blocking training crawlers is a policy choice and does not affect this result.
