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

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
ko-KR
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
0.01%
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.

Friendly URLs
Passed
The current check passed.
This heuristic detects query strings and underscores. Their presence does not make a URL invalid or unindexable.
Keep in mind
Use understandable paths and manage redundant parameters. Review existing links and redirects before changing working URLs.
There are no warning or unknown checks in this section.
Internal links0
External links0
nofollow0
Link destinations, text and attributes0 saved
Up to 300 extracted links. Destination status codes and linked pages are not individually checked.
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.

4 checks
Robots.txt
Passed
robots.txt
This checks the robots.txt response. File presence does not verify all crawler permissions or actual indexing.
Keep in mind
Review bot and path rules for your intended policy. Protect private information with authentication and access controls.
XML Sitemap
Passed
https://www.skyscanner.co.kr/sitemap.xml
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://www.skyscanner.co.kr/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.
