Free Website Readiness Check in Four States

Check your site in four states, not two

See what passed and what failed, and also what needs a person to judge and what nothing checked at all: those last two are where the failures you actually ship are hiding.

One page and a few supporting requests, robots.txt respected. We keep each result so its link works. Anyone with the link can open it. We do not publish it or list it anywhere.

Want the full report?

Every element, where it is on the page, and how to fix it — plus the checks this page could not make. We will send it and keep you posted on the private pilot.

We keep what you enter here and the page you joined from, only to contact you about the ShipperAG pilot. No spam.

What this checks

About twenty-five checks, read from the page's HTML and its response headers, grouped the way ShipperAG groups a release:

Human experience. Language declared, alternative text, accessible names on links and buttons, form labels, iframe titles, one H1, heading order, a main landmark, zooming allowed, duplicated ids.
Findability. Title length, meta description, canonical URL, social preview tags, structured data that parses, and whether the page asks not to be indexed.
Trust. HTTPS, HSTS, Content Security Policy, X-Content-Type-Options, Referrer-Policy, and clickjacking protection.
Operability. The status code, whether a missing page returns a real 404, whether a sitemap exists, and how heavy the HTML is.

What it does not check, and why that is on the report

This runs without opening a browser, so colour contrast, touch target sizes, keyboard order, focus visibility and anything that appears after a click are outside it. Those are not omitted quietly — they are listed, by name, in the fourth panel of every report.

That is the whole argument. A checker that reports "all clear" because it could not see anything is worse than one that says what it did not look at. In our scan of 410 high-traffic home pages, 74% failed a check a machine can decide — and 81% also returned checks the tool would not decide at all. Every one of those sat in a state most dashboards do not have.

If your page comes back with almost nothing in the HTML, the report will say so. That usually means it renders with JavaScript, and it is worth knowing: some crawlers and AI assistants see exactly what this check saw.

Why four states

Verified. A check ran and passed, and you can see which one.
Issue found. A check ran and failed, with the count.
Needs input. A machine got as far as it can and a person has to judge: the alt text exists, but is it accurate?
Not covered. Nothing checked it. This is the state most reports quietly leave out.

The same four states are how ShipperAG reports a whole release, against your requirements rather than one page. See the 32 WCAG criteria no tool checks for you, or the full website QA checklist for the manual half.

The free check, answered

What does this free website check actually test?

It reads the page's HTML and its response headers, and reports about twenty-five checks across four areas: accessibility (language, alternative text, accessible names, labels, headings, landmarks, zooming), findability (title, description, canonical, social preview, structured data, indexability), trust (HTTPS and four security headers), and operability (status code, real 404s, a sitemap, page weight). It does not open a browser, so contrast, touch targets, keyboard order and anything that appears after a click are listed as not covered rather than quietly passed.

Why does it report four states instead of pass and fail?

Because pass and fail hide the two states that matter most. Needs input is where a machine can see something but cannot judge it: alt text exists, but is it accurate? Not covered is what nothing checked at all. In our scan of 410 high-traffic home pages, 81% returned checks the tool would not decide. A report that shows only green and red turns that into a silent pass, which is how an apparently clean release reaches someone who cannot use it.

Is it free, and do I need an account?

Free, and no account. The summary appears immediately with no email required. If you want the full report with every element and how to fix it, you can leave an email address and we will send it. We keep each result so its link works. Anyone with the link can open it. We do not publish it or list it anywhere.
