Reliable data across every channel, from tag to reporting

Web & app tracking setup: reliable, complete, activation-ready data

Setting up tracking that holds up is far more than dropping a pixel. We structure your entire data collection — tag management, multi-platform advertising tracking, analytics and mobile tracking — on the right platforms and tools, with a clean, GDPR-compliant measurement plan. From GA4 configuration to wiring up Google Ads, Meta or Microsoft conversions (and server-side when precision demands it), you get complete, durable data that’s ready to drive your decisions.

The 3 tracking mistakes killing your performance

01

Tag Management: the clean foundation

It all starts with a well-structured Google Tag Manager (GTM) container and a documented data layer. We set a clear measurement plan, strict naming conventions and, when reliability requires it, a server-side GTM (sGTM). A foundation your teams can evolve without breaking tracking.

Our solution
02

Advertising tracking, every platform

Google Ads, Meta, TikTok, LinkedIn, Pinterest, Snapchat, Microsoft Advertising (Bing): we set up web, offline and server-side / CAPI conversion tracking where it matters. Your algorithms finally receive complete, deduplicated signals to optimize budgets better.

Our solution
03

Reliable analytics tracking

Google Analytics 4 configured by the book (events, e-commerce, audiences, conversions), or alternatives to fit your context — Matomo, Piano Analytics — for data sovereignty or industry constraints. Consistent measurement your analysis can actually rely on.

Our solution

Why it matters

30-40%of conversions lost without server-side tracking

Ad blockers, iOS restrictions (ITP, ATT) and misconfigured cookie banners cause 30 to 40% of conversions to be lost from your campaigns. Your Smart Bidding algorithms run on incomplete data. Our tracking installation recovers those lost conversions.

Our tracking installation methodology

A proven 4-step process for concrete, measurable results.

01

Audit & measurement plan

Review of your setup (GA4, GTM, pixels, app) and a complete measurement plan: events, parameters, conversions and business KPIs, validated with your marketing and tech teams. Deliverable: a clear specification that frames the whole setup.

02

Tag management implementation

A structured GTM container and a robust data layer, built with your dev team. Tags, triggers and variables organized, documented and maintainable — the backbone of all data collection.

03

Connecting platforms & tools

Wiring up your ad platforms (Google Ads, Meta, Microsoft…), your analytics (GA4 / Matomo / Piano) and your mobile tracking. We enable web, offline and server-side / CAPI conversions based on the precision required, fully respecting consent (Consent Mode v2).

04

QA, testing & documentation

End-to-end validation in staging then production, across all browsers and devices. Verification that data lands in each platform, detailed technical documentation and a training session for your teams.

Our web & app tracking installation services

Discover our specialized services

Tracking Google Ads

Conversions approximatives, dupliquées ou absentes ? Le Smart Bidding ne peut pas optimiser ce qu'il ne mesure pas : enchères erratiques, CPA qui explose, ROAS en chute. Nous installons un tracking Google Ads blindé — Enhanced Conversions, Consent Mode V2, Conversion Linker.

Tracking Meta Ads

Depuis iOS 14.5, votre Pixel perd jusqu'à 40% des conversions. Les adblockers en bloquent 15% de plus. Le Pixel seul ne suffit plus. Nous déployons Pixel + Conversions API + Aggregated Event Measurement pour restaurer vos campagnes Meta et Advantage+.

Tracking TikTok Ads

TikTok est un canal d'acquisition majeur mais son Pixel est jeune et les erreurs de tracking fréquentes. Sans Events API, l'algorithme met 3 semaines à sortir de la phase d'apprentissage au lieu d'une. Nous installons un tracking TikTok irréprochable dès le premier euro.

Tracking LinkedIn Ads

Sans Insight Tag ni tracking des conversions B2B, vos campagnes LinkedIn coûtent cher et vous payez des clics sans savoir lesquels deviennent clients. Nous optimisons votre tracking LinkedIn pour réconcilier chaque euro avec un résultat business mesurable.

Tracking Pinterest Ads

Pinterest est un moteur de découverte où les utilisateurs planifient leurs achats. Sans Pinterest Tag avec événements enrichis, vous passez à côté d'un parcours unique : de l'épingle sauvegardée à l'achat, parfois des semaines plus tard. Nous capturons cette intention.

Tracking Snapchat Ads

Snapchat touche une audience jeune et engagée introuvable ailleurs. Sans Snap Pixel optimisé mobile et sans CAPI, vous perdez la trace de ces utilisateurs mobile-first. Nous installons le tracking complet pour mesurer l'impact réel de Snap.

Tracking Bing Ads & Microsoft Advertising (UET, Server-Side)

Microsoft Advertising (Bing, Edge, Outlook, LinkedIn) touche une audience à fort pouvoir d’achat, avec des CPC souvent 30 % inférieurs à Google Ads. La plupart des annonceurs négligent le UET Tag et perdent des conversions. Nous fiabilisons votre tracking Bing Ads — UET, conversions hors-ligne et server-side — et la mesure analytics associée pour capter cette audience premium.

Google Tag Manager

Vos tags se multiplient, votre site ralentit et personne ne sait ce qui est déployé en production. Google Tag Manager centralise toute votre collecte de données dans une interface unique, avec versionning et environnements de test. Plus de scripts en dur dans le code, plus de déploiements sauvages.

Tracking App Mobile

Vous investissez en acquisition mobile sans savoir quelles campagnes génèrent de vrais utilisateurs actifs. ATT, SKAdNetwork, fragmentation Android : le tracking mobile est un casse-tête. Nous déployons la stack de mesure (MMP + SDK + attribution) qui vous redonne la visibilité.
