GA4 doesn't match your CRM
Google Ads counts 200 conversions, GA4 sees 160, your CRM closes 120. Without reconciling the sources, you make calls on instinct.
Fix your tracking, from the dataLayer to the bid.
Your conversions get lost between your site, the cookie banner and your ad platforms. We repair the chain end to end.

What approximate tracking costs you
Four flaws we find in most of the accounts we open.
A miswired Consent Mode
The banner is in place, but the consent signal arrives too late or not at all. Google models nothing: Smart Bidding only learns from visitors who accept.
100% browser-side tracking
Safari ITP, ad blockers, short-lived cookies: part of the signal never reaches your ad platforms, and your campaigns are judged on truncated data.
No tracking plan
Events named on the fly, forms counted twice, duplicates across tags. Every site redesign resets the counter to zero.
Your tracking decides what Google Ads learns.
Smart Bidding, Performance Max and AI Max learn from what you send them: fixing measurement is the first optimization.
What gets measured
A tracking plan that follows your real goals: qualified leads, sales, margin, loss leaders.
What is allowed
Advanced Consent Mode wired at the right moment, so Google can model what declined consent hides from it.
What reaches ad platforms
Server-side, Google Tag Gateway, enhanced conversions and offline conversions to recover every recoverable signal, then let Google's modeling fill in the rest.
Nobody captures 100% of sales: in France, nearly 4 in 10 visitors refuse cookies (CNIL, June 2022 data). Healthy measurement is not complete measurement: it is a clean, stable, properly valued signal that lets bidding learn from real data.

Tracking and Consent Mode: nine answers before you start
Should you move to server-side tagging?
Not always. Server-side GTM brings a real gain when a large share of traffic comes from Safari or mobile, or when volumes justify the infrastructure. We only recommend it if the audit shows lost signal that server-side recovers, and we quantify that gain first.
How long does the tracking audit take?
The free diagnosis arrives within 2 business days of account access. The full audit is delivered in less than a week. A multi-domain site or several banners extend the timeline: we say so at scoping.
Basic or advanced Consent Mode?
In basic mode, no tag loads before consent: Google models nothing. In advanced mode, cookieless pings fire as soon as the page loads and Google rebuilds part of the declined conversions. We deploy advanced mode, with the default state set before GTM loads; otherwise it arrives too late.
Do you work with our banner and our CMS?
Yes. Banners: Axeptio, Didomi, Cookiebot, OneTrust, Tarteaucitron and custom solutions. Sites: Shopify, WordPress and WooCommerce, PrestaShop, custom builds and single-page applications, where tracking needs specific care.
Audit only, or fixes too?
Both. The audit stands on its own: it is written to be carried out by your team or your developer. If you prefer, we implement the fixes right after, including QA and publishing.
How does it tie into Google Ads?
It is the reason TAGBRUT exists. The person who fixes the measurement is the one who runs the campaigns: every tracking fix is judged by its effect on Smart Bidding and ROAS. Reliable measurement is not an end in itself; it is what lets your bidding learn from real data.
Why not aim for 100% of conversions?
Because it is not achievable. In France, nearly 4 in 10 visitors refuse cookies (CNIL, June 2022 data): even with server-side GTM, Google Tag Gateway and advanced Consent Mode, part of your sales is never observed. Google restores some of it through modeling, from 700 clicks over 7 days per country. What matters is a clean, stable signal; an account that shows more sales than your back office is counting duplicates.
What does the free audit include?
A written diagnosis, delivered within 2 business days of read access to your accounts: the five most costly findings and what we would do first. It is yours, whether or not you work with us afterward.
How much does a tracking overhaul cost?
A fixed fee, in writing, after the free diagnosis and before we start. It depends on container depth and the number of ad platforms to connect.
