A canonical link signals the preferred URL among similar pages. Its presence does not confirm which URL a search engine selects.
Check that the preferred URL works and agrees with HTTPS, internal links and sitemap URLs.
This checks noindex and none directives in HTML and response headers. It does not query a search engine’s index.
Remove unintended noindex directives from public pages and check actual indexing with the search engine’s URL inspection tool.
Open Graph supplies title, description and image candidates for link previews. This check looks for those three properties.
Use page-specific sharing metadata and verify that the image URL is publicly accessible.
Card metadata describes a sharing preview format. Detecting a tag does not verify the preview shown by a platform.
Review the card type, title, description and image together, allowing for platform caching.

Viewport metadata enables device-width layouts. It is not a test of real mobile layout or touch targets.
Check width=device-width, then inspect overflow, zoom, forms and buttons on a small screen.
This detects a link declaration for a browser icon, rather than verifying its rendered appearance.
Check that the icon file loads and remains recognizable on light and dark browser surfaces.
This detects a touch icon declaration for saved home-screen shortcuts.
Review the icon’s dimensions, padding and background, then inspect it on an actual device.
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.

The doctype declaration helps browsers render HTML in standards mode.
Place <!doctype html> at the start of the document and check for unintended output before it.
Tool heuristic: up to 4 external files
This counts external stylesheet declarations. Count alone does not measure transfer size, caching or render blocking.
Inspect duplicate or unused CSS and render blocking, then prioritize changes using actual performance measurements.

This checks the HTML Content-Encoding header. Compression can reduce transfer size, with savings depending on the response.
Review text compression on the server or CDN, treating already compressed image formats separately.
Tool heuristic: at least 3 of 6 selected headers present
This detects selected security-related response headers. Their count does not establish policy quality or protection.
Review CSP, HSTS and other values for the application, then test for blocked resources or broken functionality.

Web server / CDN response headers
These headers were absent. Configure response headers in the actual server/CDN settings: .htaccess or VirtualHost for Apache, or the Nginx server block. Validate the two example headers first; design CSP/HSTS for the real resources and HTTPS policy. The actual server configuration path is not visible to this tool.

X-Content-Type-Options: nosniff Referrer-Policy: strict-origin-when-cross-origin
This checks whether the final analyzed page used HTTPS. It is not a security audit of the whole site.
Review certificate validity, mixed content and HTTPS on important linked pages and forms.
This checks whether a request starting over HTTP ends on HTTPS.
Configure consistent HTTP-to-HTTPS redirects and check for unnecessary chains or loops.
These are HTML validation results from W3C Nu, not a ranking, accessibility or security certification.

#s20This checks the robots.txt response. File presence does not verify all crawler permissions or actual indexing.
Review bot and path rules for your intended policy. Protect private information with authentication and access controls.
This detects a sitemap format at a declared or default URL. It does not crawl and validate every listed URL.
Include intended canonical URLs and meaningful update dates. Declare a custom sitemap location in robots.txt.
This checks for a text response at /llms.txt. Its presence does not guarantee use by an AI service or search visibility.
If you publish one, describe public resources accurately and keep its content and links current.
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.
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.
There are no warning or unknown checks in this section.
