OVERALL SEO SCORE
Checks are based on public HTML and responses. Review the evidence and recommended actions below.
The score excludes checks that could not be completed.
NEXT STEPS
Up to four findings, ordered by check weight.
Use H1 for the main subject and H2/H3 for logical subsections, rather than selecting levels for visual size alone.
Review CSP, HSTS and other values for the application, then test for blocked resources or broken functionality.
Do not add filler text to target a ratio. Check for useful HTML content and unnecessary markup.
Compare quality and file size, and inspect the actual delivered format in browser developer tools.
Review the observed values, context and actions for each check.

16 characters · tool reference range 10-70
The title identifies the page and its subject. The character range below is this tool’s heuristic, not a search engine limit.
Write a distinctive title, lead with the subject and avoid repeating keywords or the brand.
96 characters · tool reference range 70-160
The meta description summarizes a page. Search engines may show a different snippet for a query or device.
Describe what this specific page offers and avoid reusing the same description across every page.
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.
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.
Match markup to visible content and validate it with a rich result testing tool. Eligibility does not guarantee display.
There are no warning or unknown checks in this section.

Headings organize a page into a main topic and supporting sections. This tool checks for one H1 and shows the saved H2-H6 structure.
Use H1 for the main subject and H2/H3 for logical subsections, rather than selecting levels for visual size alone.
Targethttps://severance.healthcare/severance/index.do
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.
0
<h1>Main topic of this page</h1>
Alternative text conveys an image’s meaning. The count includes images with non-empty alt text.
Describe informative images in context. Empty alt="" can be appropriate for decorative images, so inspect their purpose before changing them.
The html lang attribute identifies the document’s primary language and helps assistive software select pronunciation.
Match lang to the main content and mark passages written in another language as appropriate.
The encoding declaration tells clients how to decode text. It must match the actual response bytes.
Keep the HTTP or HTML charset declaration consistent with the file encoding; use UTF-8 for UTF-8 content.
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.
Do not add filler text to target a ratio. Check for useful HTML content and unnecessary markup.
Targethttps://severance.healthcare/severance/index.do
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.

Meta keywords do not contribute to this tool’s score.
This counts links to the same site. Navigation and contextual links create routes to related information.
Link important pages with standard a href links and use text that describes the destination.
This heuristic detects query strings and underscores. Their presence does not make a URL invalid or unindexable.
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.
Up to 300 extracted links. Destination status codes and linked pages are not individually checked.
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.
Targethttps://severance.healthcare/severance/index.do
Response HTML <head>
Prepare a home-screen icon and declare its real path rather than adding a tag without a file.
<link rel="apple-touch-icon" href="/apple-touch-icon.png">
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.
Compare quality and file size, and inspect the actual delivered format in browser developer tools.

This detects loading="lazy" on img elements. Pages with few images can pass the tool’s heuristic without it.
Consider lazy loading below-the-fold images while keeping prominent first-screen images promptly available.
There are no warning or unknown checks in this section.
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.
Targethttps://severance.healthcare/severance/index.do
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.
Content-Encoding: gzip
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.
Targethttps://severance.healthcare/severance/index.do
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.
Check network restrictions and provider availability before retrying. An unknown result is not a confirmed failure or a zero score.
There are no warning or unknown checks in this section.

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.
