6/15

Invisible

6 of 15 checks passed · Standard v1.2 · Engine 0.1.0-m0

Hard gate failed. At least one group A check failed, so the verdict is capped at “Invisible” however well the rest of the page scores. Group A asks whether an AI engine can reach the page at all.

Positioning: English-language site aimed abroad (overseas). The hard gate depends on this: an English-language site is measured on the international AI crawlers, a Chinese-language site on the China ecosystem.

Fix in this order

  1. A3 A sitemap exists A failed group A check caps your grade at Invisible however well everything else scores, so this one unlocks the grade.
  2. C3 There is original data or first-hand information 93% of the sites we have measured fail this check — it is the common case, not an edge case.
  3. B2 Structured data (JSON-LD) is present 86% of the sites we have measured fail this check — it is the common case, not an edge case.
  4. C4 There is a visible last-updated date 86% of the sites we have measured fail this check — it is the common case, not an edge case.
  5. B4 An llms.txt is present 79% of the sites we have measured fail this check — it is the common case, not an edge case.
  6. B1 Title and description are complete 64% of the sites we have measured fail this check — it is the common case, not an edge case.

A. Can AI reach you?

Can an AI engine reach the page at all?

  1. A3 A sitemap exists Fail

    /sitemap.xml was returned but does not look like a sitemap (<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initi…).

    How to fix it. Replace the file currently served at /sitemap.xml, which returns an HTML page instead of XML, with a real sitemap listing the site's URLs. Right now a crawler asking for the sitemap gets an HTML document, so it learns nothing about the site's pages.tailored to this site

  2. A1 robots.txt allows the AI crawlers Pass

    All 11 international AI crawlers may fetch the site (0 declared explicitly).

  3. A2 Content is in the HTML, not only after JavaScript Pass

    The raw HTML already contains 2110 characters of readable text, so a crawler that does not run JavaScript can read the page.

  4. A4 No dead-link pollution Pass

    0 of 11 checked internal link(s) failed (0.0%), below the 1% threshold.

  5. A5 Reachable and HTTPS is valid Pass

    The homepage answers HTTP 200 over HTTPS and certificate valid for 41 more day(s); no mixed content found.

B. Can AI understand who you are?

Can it tell who you are and what the page is about?

  1. B1 Title and description are complete Fail

    Problems: title is 109 characters (aim for 10-70). Title: "⏰VClocks - timer & alarm clock & alarm clock online & Timer Tools Full-screen t…"; description: "VClocks.com offers digital clock, world time, timer, stopwatch, countdown, alarm and loca…".

    How to fix it. Shorten the title to roughly 10–70 characters and make the description a complete, specific summary; the current title runs to 109 characters and is cut off in the evidence. Both should name what the site actually offers rather than repeat terms like 'alarm clock'.tailored to this site

  2. B2 Structured data (JSON-LD) is present Fail

    No application/ld+json block was found.

    How to fix it. Add a JSON-LD block to the page's HTML, since none was found. A minimal WebSite or WebApplication entry gives crawlers machine-readable facts about the site instead of forcing them to infer from prose.tailored to this site

  3. B3 Heading hierarchy is semantic Fail

    Problems: no <h1>. Structure: 8 headings in total (h2 × 2, h3 × 6); the page opens h2 → h2 → h3 → h3 → h3.

    How to fix it. Add one <h1> that states the page's main subject and reorder the existing headings so the sequence descends properly; the page currently opens with two h2s and has no h1. Keep the six h3s nested under the headings above them.tailored to this site

  4. B4 An llms.txt is present Fail

    llms.txt exists but is minimal (1037 non-empty line(s), 0 link(s)).

    How to fix it. Expand llms.txt so it points to the site's key pages; it currently has 1037 non-empty lines but zero links. A file with no links does not direct a model to any content.tailored to this site

  5. B5 The operator behind the site is verifiable Fail

    Only 1 trust signal(s) found: a copyright line; we look for at least 2: an about/contact link, an email address, a phone number, a postal address, a copyright line, or Organization markup. Anonymous sites are rarely treated as citable sources.

    How to fix it. Add a second trust signal beyond the existing copyright line, such as an about or contact page, an email address, or Organization markup. A single copyright line is not enough for the site to be treated as a citable source.tailored to this site

    This rule cannot decide reliably on its own (confidence 80%), so treat it as a suggestion rather than a verdict.

C. Will AI choose to cite you?

Will it choose to quote you rather than someone else?

  1. C1 The conclusion comes first Fail

    The first paragraph is only 33 characters: "Double click clock for fullscreen".

    How to fix it. Replace the opening line 'Double click clock for fullscreen' with a first paragraph that states the page's main point in full sentences. The current opening is 33 characters and carries no answer.tailored to this site

    This rule cannot decide reliably on its own (confidence 70%), so treat it as a suggestion rather than a verdict.

  2. C3 There is original data or first-hand information Fail

    Only 0 percentage figure(s) and 0 data point(s) were found — mostly generic prose.

    How to fix it. Add first-hand data the site itself can stand behind, such as specific figures or measurements from its own operation; the page currently contains no percentage figures and no data points. Generic description alone gives nothing to cite.tailored to this site

    This rule cannot decide reliably on its own (confidence 60%), so treat it as a suggestion rather than a verdict.

  3. C4 There is a visible last-updated date Fail

    No updated date was found in the page text or metadata.

    How to fix it. Add a visible last-updated date to the page text or metadata, which is currently absent. Readers and crawlers have no way to tell whether the content is current.tailored to this site

  4. C2 There are extractable structure blocks Pass

    Found a step-by-step section — these can be lifted out of the page as a self-contained answer.

  5. C5 There is third-party reference evidence Pass

    7 distinct external domain(s) referenced.

Analysis · written from the measurements above

The site is readable by AI crawlers and its content is present in the raw HTML, but the signals that make a page citable are largely missing: the sitemap URL returns an HTML page instead of a sitemap, there is no JSON-LD, no <h1>, no visible last-updated date, and only one trust signal (a copyright line). Because the operator cannot be verified and the page offers no original data, AI systems have little reason to treat it as a source. First, replace /sitemap.xml with a real XML sitemap and add an about/contact link plus an Organization JSON-LD block, then fix the heading hierarchy and trim the title to 10–70 characters.
