Your site works. Do you know what you’re not seeing?

Don’t let your customers find the problems first.

An independent audit that checks your site against 9 pillars: security and encryption, performance, search visibility, accessibility, compliance and privacy, domain and network, independence and resilience, content and trust, experience and reliability.

You don’t just get a score. We measure, we check, and we show you what’s working, where you’re exposed, and what to fix first.

Audit my siteInside the 9 pillars

From €200 excl. VAT · No access needed · Payment collected on delivery

Nothing to install, no access to hand over We look at your site the way a visitor does.
Nothing is assumed compliant If we couldn’t verify it, it’s never counted as compliant.
The report is yours Pass it on unchanged, to your team or to your provider.

Audit your home page for free

We look at your home page for the pillar you pick, and we email you our report within 48 working hours.

One page, one pillar. The plans cover the 9 pillars across your whole site.

What you’re buying

An independent picture of your site, in four answers:

What works

So you don’t rebuild what doesn’t need it.

What’s wrong

With the pages it affects, and the values we measured.

Where to start

To tell the real problems from the secondary ones.

A document to pass on

To your team, your agency, your developer, your adviser or a buyer.

You don’t need to buy anything else to use the report.

Nine pillars, not search rankings alone

Most “website audits” look at one subject: search, speed or accessibility. Ours covers the 9 pillars that decide whether your site works for you, examined across the pages of your plan. Each one settles a question you’re already asking, and leans on a law, a standard or a specification wherever one exists, rather than on our opinion.

PillarThe question it settlesOn what basis
Security and encryptionAre exchanges with your visitors protected?Recommended TLS versions, RFC 9116
PerformanceDoes the site render fast enough to keep the visitor?Core Web Vitals
Search visibilityDo search engines understand your pages well enough to rank them?schema.org, RFC 9309
AccessibilityCan the site be used with a disability?WCAG 2.2 AA, RGAA, EU Directive 2019/882
Compliance and privacyAre the legal obligations met?GDPR, ePrivacy, CNIL, LCEN
Domain and networkAre the domain and the mail service protected?SPF, DKIM, DMARC (RFC 7489), DNSSEC
Independence and resilienceWhere does your data live, and who do you depend on?GDPR, CLOUD Act
Content and trustDoes the content carry authority, for your readers and for AI?Google's E-E-A-T, schema.org
Experience and reliabilityDoes the journey really work, on a phone included?no dedicated standard: measured facts and human review

What you receive, and how to read it

Three PDF documents, in the language you choose when you order (French or English):

The report

Opens with a summary that reads without technical background: the overall score and its weighting, where you’re exposed, what can wait. Then each pillar, scored and justified.

The page-by-page analysis

Your pages one by one: what we observed on each, where, and the measured value. The working document for whoever comes in afterwards.

The methodology note

How each point was checked, and where the limits were: the exact scope of what the audit claims.

Two levels of reading: the summary to decide with, the page-by-page analysis to fix from. Hand the documents straight to whoever looks after your site.

The audit covers what is observable from outside your site. Every limit of the examination is written in the methodology note: an audit that finds nothing because it never looked is false reassurance.

What’s an audit for?

Before you invest

A rebuild, an acquisition, a funding round: the audit puts numbers on what exists, so the next step rests on facts rather than on the quotes you’re handed.

To understand

The site is live, but nothing much comes of it. The audit cross-checks the 9 pillars to find where it stalls, and where to start.

To meet your obligations

Legal notice, cookies, personal data, accessibility: obligations already apply to your site.

Six situations where the audit changes the decision →

How it works

  1. Choose your plan. The same method across the 9 pillars; only the number of pages analysed changes, and a whole site is quoted separately. A page analysed is a page of your site that we open, examine and measure across the 9 pillars.
  2. Order. Give the public address of your site and the language for your documents. The amount is temporarily authorised on your card, without being collected.
  3. We measure. Each page is opened in a browser, the way a visitor would, and we record what actually happens. Your site only sees read-only visits: no form sent, no account created.
  4. You receive your audit within the turnaround your plan states: three PDF documents, the audit report, the page-by-page analysis and the methodology note. Payment is collected at that point.

Who runs these audits?

We are Z29K, a French company providing digital services. We first ran these audits for our own customers, then decided to open them to everyone. Beyond audits, we take care of much of the digital side for companies: helping to decide, designing, building and running a site through to production.

This audit reflects the way we work: measure instead of assuming, write down what we could not verify, tell what leaves you exposed from what can wait. If the report makes you want to go further (implementation, ongoing advice, a second measurement), write to us.

We tell you which plan fits
