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.
Targets and suggested changes
Targethttps://inha.com/page/main
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.

Language
Passed
ko
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
Needs review
8.53%
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.
Recommended action
Do not add filler text to target a ratio. Check for useful HTML content and unnecessary markup.
Targets and suggested changes
Targethttps://inha.com/page/main
main / body
Check whether main content exists in the initial HTML. Consider server rendering for missing core text; do not add filler to target a ratio.

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.

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
Needs review
The expected configuration was not detected.
This checks the HTML Content-Encoding header. Compression can reduce transfer size, with savings depending on the response.
Recommended action
Review text compression on the server or CDN, treating already compressed image formats separately.
Targets and suggested changes
Targethttps://inha.com/page/main
Server / CDN compression settings
Enable actual gzip/Brotli compression for this response and verify transfer size. Do not manually add Content-Encoding without compressing the body.
View evidence and example changes
Example - adapt to the actual content and environment
Content-Encoding: gzip
Security headers
Needs review
2/6
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://inha.com/page/main
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 detects a sitemap format at a declared or default URL. It does not crawl and validate every listed URL.
Keep in mind
Include intended canonical URLs and meaningful update dates. Declare a custom sitemap location in robots.txt.
llms.txt
Needs review
The expected configuration was not detected.
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://inha.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
AI search/answer bots allowed 5/5 · training bots allowed 3/3
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.
Keep in mind
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.
