This page describes the assessment in detail: what I examine, how I work, what you get and what it costs. I review your own tracking data — analytics, Search Console, advertising platforms, sitemap and source code — and put on paper what is there, citing sources and distinguishing between facts and interpretation.
Independent review
Marketing agencies typically deliver value for money. The problem lies elsewhere: they report on their own efforts, in their own jargon, to someone who cannot verify if those efforts are profitable. As long as no one on your side of the table is reading the numbers, every report is, by definition, the final word.
That is not bad faith. It is a structural gap. An assessment bridges that gap — not to undermine your supplier, but to base the conversation with them on facts rather than trust alone.
I never enter a file with a preconceived conclusion. If it turns out good work is being delivered, that is exactly how it will be documented — backed by the numbers. Every report opens with what your supplier is demonstrably doing well, before a single critical finding is presented.
In practice, such a relationship slowly drifts that way. In the first months results are discussed, then the conversation shifts to activities, and after a year the meeting is about next month's planning. Nobody decided that; it simply happened. An assessment puts the conversation back on return, once.
Are conversions actually being registered correctly? If the tracking is off, any discussion about results is meaningless. This is a problem more often than people think.
Not just how many visitors arrive, but where they land, where they drop off, and which pages actually lead to contact — per page, per channel, and over multiple years.
Publication dates, edit history, and sitemap data reveal when your site was actually worked on, and when a technical update simply gave dozens of pages a new timestamp simultaneously.
Search Console data on positions, impressions, and clicks, contrasted with the keywords where the actual volume in your market lies.
Spend, clicks and conversions per campaign in Google Ads and Meta, set against what actually comes out of it. Without the real spend, nobody can calculate return — only volume.
What is under the hood, and whether the delivered quality matches what is being invoiced.
Structure, accessibility, trust signals, and visibility, compared side-by-side.
Whether ChatGPT, Perplexity, Copilot, and Gemini can cite your company correctly — a channel that becomes visible in your own tracking data once someone looks for it, yet rarely appears in reports.
From practice
What an independent reading of your own numbers delivers. Amounts and sectors are altered, the findings are not.
I build websites myself. If an assessment reveals that your website needs to be replaced, I am one of the parties who could profit from that. That is why these agreements are firmly established:

Every assessment is personally prepared by me from A to Z. Not because it cannot be outsourced, but because I enjoy doing it myself. A single case file brings everything together: data analysis, search performance, technology, performance, improvement roadmaps, and how AI is changing them today. After thirty-five years, that is still the work I gladly stay up late for.
From 2011 to 2016, through Awali, I provided SEO, Google Ads and Analytics advice and training to companies and governments, certified for the Google tools. So I know how such reporting is created, which numbers look good by default, and where there is room for improvement.
Before and after that, I built companies. My first company — ITsolutions — implemented ERP systems in Navision, better known today as Microsoft Dynamics 365 Business Central; it is no coincidence this site carries that name. PromoButler grew into Belgium's largest retail platform with over 3 million visitors per month, without any media budget, with practically every Belgian retailer as a client. I founded the purchasing groups Qcom and Qresellers (over 150 million euros in combined revenue) and owned EuroSys (B2B) and the retail chain Auva (B2C), together accounting for over 40 million euros in revenue and 250 IT professionals, until their acquisition in 2023.
Master of Business Engineering in Management Information Systems (UHasselt, cum laude). Google Analytics Certified.

instead of €2.250
you save €500introductory rate, excl. VAT, up to and including 31 December 2026
Condition of the introductory rate
The introductory rate applies only if we may include your report anonymised in our portfolio. If you prefer not to, the standard rate of €2.250 applies.
Thereafter €2.250. Fixed price, fixed scope, regardless of the outcome.
A maximum of three cases per month. Each case is personally prepared; there is simply no capacity for more. If the month is full, you will immediately hear when there is availability again.
No. The report is sent to you, not to them. What you do with it is up to you. Most clients simply present the findings during the next meeting — and a vendor that does good work gets a client in return who finally understands what they are paying for.
Then that will be in the report, backed by the data. That is not a failed assignment. You will know that your budget is well spent, and that is exactly what you paid for.
Expect two to three weeks from the moment I have access to your analytics data.
Read access to Google Analytics and Search Console, to Google Ads, Meta Ads and any other advertising platforms you use, and to your Google Business Profile. In addition, the reports and quotes from your current supplier, and the invoices for the media budget over the past twelve months. Read access is enough — I never ask for admin rights.
No. That analysis examines how well your site can be found by search engines and AI assistants. A review covers the full commercial return on your digital efforts, including the work of third parties.
Are you an agency or supplier yourself? I also work on behalf of agencies that want to have their own work independently measured.
