Nearly a third of your visitors block your pixel. I put those conversions back in the loop in under ten days.

Your ad platforms optimise without them and spend anyway. I rewire consent, your platforms and your CRM onto a single piece of infrastructure: yours. You keep the keys, and the code belongs to you.
Every platform needs a conversion signal to learn from. Between your customer's browser and their servers, part of that signal quietly disappears. The algorithm keeps spending regardless. It just learns less well.

The most valuable sale on this list is the one your ad platforms will never hear about.
Five ways to lose money without ever seeing it on an invoice. Every figure links to its source, so you can check all of it.
Out of a hundred people landing on your site, around thirty do not exist for your ad platforms. You paid for their click, you will never know what they did next. Global, all devices, Q2 2025, and Europe sits above it.
SourceBacklinko, ad blocker usage statisticsThe median gap Meta measures between advertisers sending conversions server-side and those staying on the pixel alone. You cut campaigns that were profitable and keep ones that are not: the decision is wrong before it is even made.
SourceMeta, about the Conversions APIBelow 6, the algorithm stops optimising on people and starts optimising on noise. It spends your budget at exactly the same rate, it simply aims worse. That is the usual score for a pixel-only account: Meta rates 6 good, 8 great.
SourceMeta, about event match qualityAs soon as the URL carries an ad identifier, the cookie's life drops to a single day. The prospect who comes back two days later is a stranger: you pay a second time to go and find someone you had already bought.
SourceWebKit, Intelligent Tracking Prevention 2.3That is the ceiling of the French regulator's simplified procedure, the one that lands in months rather than years. Under the ordinary procedure it reaches 4% of worldwide turnover. Across more than 500 sites run through the scanner, two out of three fire their ad scripts before anyone touches the banner.
SourceCNIL, the simplified sanction procedureConsent, your ad platforms and your CRM do not talk to each other. I wire them onto a single piece of infrastructure, yours, and what used to fall between the three finally arrives.
Each one sells on its own and fixes a problem you already have. Together they form the complete engine, because no block stands up without the one before it.
Your site stops being a legal liability and becomes infrastructure that belongs to you.
Your ad scripts fire before the visitor has touched the banner. The banner is decorative, and you are one complaint away from an audit.
The banner actually commands the scripts, European compliance is in place, and your data travels through your own domain instead of somebody else's.
Your ad platforms stop learning from scraps and go back to working for you.
Meta and Google see a fraction of your conversions. Your campaigns never really leave the learning phase, your cost per lead climbs, and nobody can say why.
The algorithms receive complete, hashed purchase signals. They target better, learn faster, and your acquisition cost comes back down.
The blind spot between your sales team and your marketing disappears, with the numbers to prove it.
Your reps sign contracts marketing cannot tie back to a campaign. Google and Meta optimise on filled-in forms, never on revenue.
Every euro collected traces back to the campaign that produced it. Budget moves on its own toward the audiences generating real revenue, and your leadership finally sees the whole line.
All three blocks at once, from lawful collection on the site through to revenue fed back into your campaigns. It is what most projects end up taking, because the blocks are only interesting wired to each other.
Around ten days of build, depending on CRM complexity.
It breaks when an API changes version, when a browser tightens its rules, when the site is rebuilt on a Friday night. Two formulas, depending on whether you want to sleep at night or move faster.
You never again learn from your agency that collection has been down for three weeks.
Everything above, plus someone using that data to bring your costs down.
Storylink is an attribution platform I have been running in production since 2021, for clients in France, the United States, the United Kingdom and Australia. The scanner and the monitoring came out of it: what it took to keep it running became a diagnostic tool and a monitoring tool. Those two work on your engagements.
Five years building attribution that holds. One tracking link, and every sale finds its origin again: the campaign, the audience, the channel. Including when the contract is signed over the phone months after the first click. Version 0.1 in 2021 for five clients, public version in October 2024.
You give it a URL, you get the state of your tracking in a minute: which tools are actually running, which events fire, what goes off before consent, and the order of magnitude of what you are losing. No sign-up, the report is yours. More than 500 sites have been through it.
Wired into your infrastructure, it checks continuously that everything holds. The day a stream stops, you hear it from an alert rather than from a hole in your month-end numbers. It runs in production at my clients today.
The architecture I build belongs to you. I can host it on my servers or on yours, whichever you prefer. But the day the engagement ends, you leave with it. The code, the infrastructure, the history. No subscription to cancel, no third-party tool holding you hostage, nothing to buy back to keep measuring.
Three situations, one symptom: ad spend on one side, revenue on the other, and nothing reliable left in between.
You run dozens of accounts and have no senior tracking engineer in-house. I work as invisible subcontracting or as a declared technical partner, whichever suits you.
You have HubSpot or Salesforce in place, you run inbound and outbound, and you cannot tie your signatures back to the campaigns that produced them.
Shopify Plus or heavily customised WooCommerce, dependent on Meta and Google, directly exposed to iOS signal loss and ad blockers.
Eleven years writing code before I wrote any of it for measurement. That is why what you get is infrastructure rather than a configuration: the server, the pipelines and the code holding them together are my original trade. I have practised it for companies ranging from the very small to CAC 40 groups.
For the last seven years that code has served measurement. I have worked in web analytics on large accounts, among them Banque Populaire and Caisse d'Épargne. Since 2021 I have been running Storylink in production.
You pick a slot, and I go through your site before we speak: what fires without consent, what no longer reaches your ad platforms, and the order of magnitude it costs you. You leave with the diagnosis, whether or not the rest happens with me.
No commitment. The diagnosis is yours, shareable internally.
