NEXT STEPS

Recommended next steps

Up to four findings, ordered by check weight.

01

Title

Write a distinctive title, lead with the subject and avoid repeating keywords or the brand.

 02

Image alt

Describe informative images in context. Empty alt="" can be appropriate for decorative images, so inspect their purpose before changing them.

 03

Viewport

Check width=device-width, then inspect overflow, zoom, forms and buttons on a small screen.

 04

Security headers

Review CSP, HSTS and other values for the application, then test for blocked resources or broken functionality.

Detailed findings

Review the observed values, context and actions for each check.

02

Content and images

5 checks

Headings

Passed
H1 1 / H2 29 / H3 34

Headings organize a page into a main topic and supporting sections. This tool checks for one H1 and shows the saved H2-H6 structure.

Keep in mind

Use H1 for the main subject and H2/H3 for logical subsections, rather than selecting levels for visual size alone.

Image alt

Needs review
432 images; 393 with non-empty alt; 39 empty or missing

Alternative text conveys an image’s meaning. The count includes images with non-empty alt text.

Recommended action

Describe informative images in context. Empty alt="" can be appropriate for decorative images, so inspect their purpose before changing them.

18 targets; the first five are shown. Review the full saved list in the details below.

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
ks_c_5601-1987

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
5.04%

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://www.yes24.com/Main/default.aspx

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.

Viewport

Needs review
width=1170

Viewport metadata enables device-width layouts. It is not a test of real mobile layout or touch targets.

Recommended action

Check width=device-width, then inspect overflow, zoom, forms and buttons on a small screen.

Targets and suggested changes

Targethttps://www.yes24.com/Main/default.aspx

HTML response line 11 · /html[1]/head/meta[6]

Update the existing viewport tag instead of duplicating it, then check the mobile layout.

Example - adapt to the actual content and environment
<meta name="viewport" content="width=device-width, initial-scale=1">

Favicon

Passed
The current check passed.

This detects a link declaration for a browser icon, rather than verifying its rendered appearance.

Keep in mind

Check that the icon file loads and remains recognizable on light and dark browser surfaces.

Apple touch icon

Needs review
The expected configuration was not detected.

This detects a touch icon declaration for saved home-screen shortcuts.

Recommended action

Review the icon’s dimensions, padding and background, then inspect it on an actual device.

Targets and suggested changes

Targethttps://www.yes24.com/Main/default.aspx

Response HTML <head>

Prepare a home-screen icon and declare its real path rather than adding a tag without a file.

Modern images

Needs review
0/432

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

Lazy loading

Needs review
0/432

This detects loading="lazy" on img elements. Pages with few images can pass the tool’s heuristic without it.

Recommended action

Consider lazy loading below-the-fold images while keeping prominent first-screen images promptly available.

Targets and suggested changes

Add loading="lazy" only if this image is below the initial viewport. Keep prominent initial-viewport images eager.

Technical checks

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

Needs review
9

Tool heuristic: up to 4 external files

This counts external stylesheet declarations. Count alone does not measure transfer size, caching or render blocking.

Recommended action

Inspect duplicate or unused CSS and render blocking, then prioritize changes using actual performance measurements.

JavaScript files

Needs review

Tool heuristic: up to 6 external files

This counts script elements with src attributes. File count alone cannot measure execution cost or responsiveness.

41 targets; the first five are shown. Review the full saved list in the details below.

Compression

Passed
gzip

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://www.yes24.com/Main/default.aspx

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.

HTTPS

Passed
https://www.yes24.com/Main/default.aspx

This checks whether the final analyzed page used HTTPS. It is not a security audit of the whole site.

Keep in mind

Review certificate validity, mixed content and HTTPS on important linked pages and forms.

HTTPS redirect

Passed
https://www.yes24.com/Main/default.aspx

This checks whether a request starting over HTTP ends on HTTPS.

Keep in mind

Configure consistent HTTP-to-HTTPS redirects and check for unnecessary chains or loops.

W3C validity

Not checked
Not verified in this analysis.

These are HTML validation results from W3C Nu, not a ranking, accessibility or security certification.

Recommended action

Check network restrictions and provider availability before retrying. An unknown result is not a confirmed failure or a zero score.

Search and AI crawlers

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.yes24.com/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

Passed
llms.txt

This checks for a text response at /llms.txt. Its presence does not guarantee use by an AI service or search visibility.

Keep in mind

If you publish one, describe public resources accurately and keep its content and links current.

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.
