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.
Targets and suggested changes
Targethttps://example.com/
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.

Headings
Needs review
H1 0 / H2 0 / H3 0
Headings organize a page into a main topic and supporting sections. This tool checks for one H1 and shows the saved H2-H6 structure.
Recommended action
Use H1 for the main subject and H2/H3 for logical subsections, rather than selecting levels for visual size alone.
Targets and suggested changes
Targethttps://example.com/
Body h1 elements
If multiple H1s are shown, choose the main topic and use suitable subsection levels for the others. If absent, add the main heading near the start of content.

<h1>Main topic of this page</h1>
Image alt
Passed
0 images; 0 with non-empty alt; 0 empty or missing
Alternative text conveys an image’s meaning. The count includes images with non-empty alt text.
Keep in mind
Describe informative images in context. Empty alt="" can be appropriate for decorative images, so inspect their purpose before changing them.
Language
Passed
en
The html lang attribute identifies the document’s primary language and helps assistive software select pronunciation.
Keep in mind
Match lang to the main content and mark passages written in another language as appropriate.
Charset
Passed
utf-8
The encoding declaration tells clients how to decode text. It must match the actual response bytes.
Keep in mind
Keep the HTTP or HTML charset declaration consistent with the file encoding; use UTF-8 for UTF-8 content.
Text/HTML ratio
Passed
29.64%
Tool reference range 15-70%; not an official ranking threshold.
This compares visible text length with HTML length. It cannot determine content quality or rankings on its own.
Keep in mind
Do not add filler text to target a ratio. Check for useful HTML content and unnecessary markup.
There are no warning or unknown checks in this section.

KeywordsFrequency and metadata
Word occurrence counts from extracted content, not search demand or keyword rankings.
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.
Keep in mind
Compare quality and file size, and inspect the actual delivered format in browser developer tools.
Lazy loading
Passed
0/0
This detects loading="lazy" on img elements. Pages with few images can pass the tool’s heuristic without it.
There are no warning or unknown checks in this section.

8 checks
Doctype
Passed
html
The doctype declaration helps browsers render HTML in standards mode.
Keep in mind
Place <!doctype html> at the start of the document and check for unintended output before it.
CSS files
Passed
0
Tool heuristic: up to 4 external files
This counts external stylesheet declarations. Count alone does not measure transfer size, caching or render blocking.
Keep in mind
Inspect duplicate or unused CSS and render blocking, then prioritize changes using actual performance measurements.
JavaScript files
Passed
1
Tool heuristic: up to 6 external files
This counts script elements with src attributes. File count alone cannot measure execution cost or responsiveness.
Keep in mind
Review duplicated scripts and expensive startup work; consider defer, async or delayed execution where appropriate.
Compression
Passed
br
This checks the HTML Content-Encoding header. Compression can reduce transfer size, with savings depending on the response.
Keep in mind
Review text compression on the server or CDN, treating already compressed image formats separately.
Security headers
Needs review
0/6
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.
Recommended action
Review CSP, HSTS and other values for the application, then test for blocked resources or broken functionality.
Targets and suggested changes
Targethttps://example.com/
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.
This checks for a text response at /llms.txt. Its presence does not guarantee use by an AI service or search visibility.
Recommended action
If you publish one, describe public resources accurately and keep its content and links current.
Targets and suggested changes
Targethttps://example.com/llms.txt
/llms.txt
If desired, publish UTF-8 text at the root and add real public documentation links. This is optional.

AI crawlers
Passed
5/5
This interprets root-path robots.txt rules for five bots. Training and search crawlers have different purposes; actual citations are not checked.
Keep in mind
Decide access for each bot according to your policy rather than automatically allowing every crawler.
