website intelligence

Wefindwhatblocksyourwebsite.

A website audit without a single score and without a generic checklist. We combine a crawler, real browser measurements, screenshots, performance, technical SEO and available marketing data, and trace problems back to causes and priorities.

Performance and Core Web Vitals
Responsive and visual QA

Tracking and analytics
Content and internal links

every conclusion comes with a source

We only present as fact what we can back up.

Confirmed
Canonical language versions wrong. Five language homepages pointed to the Dutch one.
measured · raw html, crawler, sitemap · not available: search console
Indication
Organic growth potential on non-brand keywords.
third-party · ahrefs · still to confirm with search console

Four source levels: measured ourselves, first-party client data, third-party estimate, analysis. And a level of certainty: confirmed, strong evidence, likely, still to verify. A tool warning is not a business truth.

We only publish results after implementation and a follow-up measurement. Not 'SEO improved', but 'internal links to redirects from X to 0, own crawl, date A against date B'.

lab is not field

A score is not the same as real user data.

We use Lighthouse to find causes under controlled conditions. Where available we also look at real users through CrUX or our own measurements. When optimising a website we keep the two strictly apart. At A'DAM VR: lab 28 → 76, field LCP 2.3 s → 465 ms.

A website can look fine and still leave a lot on the table, technically, in its measurement or commercially.

So we look further than an automated SEO scan or a single Lighthouse score. We research what actually happens, which problems share a cause and which points need attention first.

Who it is for. Organisations with an existing website that delivers less than expected, teams who doubt their data or technical foundation, and anyone facing a migration or rebuild who first wants to know what they are taking over.

What do we research?

The exact scope differs per website. Among other things technical SEO, crawlability, indexability, redirects, canonicals, structured data, performance, Core Web Vitals, responsive behaviour, accessibility, tracking, analytics, conversion paths and search data. Where possible we combine sources: an error in a crawler is not automatically a problem for Google, and a high bounce rate without context does not tell the whole story.

What do you get?

No export with hundreds of red dots. A reasoned overview of what we saw, how we established it, why it matters, how certain we are and what needs to happen. We turn that into a priority list for you, your current agency or blokwerk to work from.

What is not included by default?

The audit is the research. Implementing the improvements we find is not automatically included. We can only draw conclusions from sources we have access to. If Search Console, analytics or source code is not available, we say so.

Why €2,000 – €5,000+?

A twenty-page website is a different job from a multilingual platform with thousands of URLs, several templates, external scripts, ads and different data sources. The price depends on the size of the website, the number of research layers and how much data we need to analyse.

First check

Want to know first whether a full audit makes sense? Then we start with a short check of the most important visible signals. Not a complete study. Enough to decide whether something needs a closer look.
