What our tracking support covers

Tagging plan and implementation

We define with your teams what needs measuring, and write it into a tagging plan: every event, its parameters, its expected value. Implementing the dataLayer is developer work, which we support, or we set the tagging up ourselves in GTM. Then we configure the container: the tags, their triggers and their variables.

Tagging plan: the specification of one event, its parameters and the expected code — Tailored to your web environment and your business goals, tool-agnostic. It carries all the intelligence of the tagging: precise, written for developers, readable by marketing teams.

QA and data quality

We have built solid processes, combining human review and agentic workflows, for the QA phase. They help your technical teams implement the tagging plan correctly, and verify that requests do reach your analytics tools and your ad platforms.

Tracking QA: one request broken down parameter by parameter, with its verdict

Monitoring and alerts

The data collected also lands in your warehouse, which is what makes real monitoring possible. We set alert rules on volumes, missing parameters and consent rates, and the notification goes to Slack, ours and yours.

Collection alert raised in Slack, with expected volume and observed volume — Tracking can break when your site changes. An alert rule sees it happen, and the notification reaches Slack with enough context to open the topic right away.

Run and evolutions of the setup

An EdgeAngel consultant stays embedded in your teams. They keep the collection standard as the site evolves, set up the new tags, connect the new ad platforms and work through the optimisation backlog, on topics agreed together. Every month, data quality, the automated audit of the setup and the governance meeting are included.

Running a tracking setup: the month's backlog by type and priority, and what is included every month — The setup lives at the pace of your site. The run keeps it reliable and evolves it, on a monthly rhythm, with topics decided together.

Frequently asked questions about web analytics

What tools do you recommend for web tracking and user performance analysis?

We recommend a combination of high-performance tools for effective tracking:

Analytics: Google Analytics, Piano Analytics, Matomo.
Tag Management: Google Tag Manager (GTM) and Server-side Tag Manager (sGTM).
Orchestration: Segment, RudderStack, Custom Data Platform (e.g. Capture) for the most mature players wishing to manage more complex data pipelines.

These tools allow collecting precise data on user behaviors and measuring the effectiveness of your marketing campaigns.

What is good web tracking and why is it essential for marketing?

Good web tracking allows collecting reliable, complete, and usable data. Without quality data, all analyses (attribution, CRO, AI) become approximate.

Solid tracking:

Guarantees a unified view of the user journey (site, product, acquisition, CRM)
Feeds marketing and business KPIs without bias
Allows optimizing media budgets (Google Ads, Meta, LinkedIn...)
Constitutes the foundation of AI and personalization projects

Imperfect tracking leads to:

Loss of measured conversions and under-optimized campaigns
Business decisions based on erroneous signal
Under-performing marketing ROI

How to guarantee GDPR / ePrivacy compliance in web tracking?

Compliance is not a brake: it is a framework that secures companies. Solid compliance relies on:

A correctly configured CMP (Didomi, OneTrust, Axeptio, etc.)
A tagging plan aligned with consent
A Google Consent Mode v2 or Microsoft Consent Mode correctly implemented
A documented and mastered vendor catalog
Continuous compliance monitoring (and not only at deployment time)

EdgeAngel guarantees privacy-by-design tracking, so that data remains reliable, usable, and 100% compliant.

What is server-side tracking and is it essential today?

Server-side tracking (with sGTM) allows collecting data directly on the server, thus bypassing browser and ad blocker limitations. It answers 3 key challenges:

Data loss due to blockers, ITP, and browser restrictions
Security and control of data flows (no third-party script execution browser-side)
Advanced marketing activation (enriched CAPI integrations for Meta, Google, LinkedIn, TikTok...)

Concrete benefits:

+20 to +60% usable data on certain media platforms
Better quality of campaign optimization signals
Enrichment of conversions (value, basket, product category...)

Is Google Analytics 4 sufficient to analyze site or marketing activity performance?

GA4 is an excellent tool, but it is not always sufficient on its own. It excels for:

Site-centric analysis (tunnel, events)
Acquisition source tracking
Multi-device audience measurement

But it reaches its limits for:

Analyzing product data (Product Analytics)
Exploiting CRM or first-party data
Performing advanced marketing analyses (LTV, complex cohorts)
Directly activating data to media platforms

A complete approach often relies on a hybrid ecosystem: GA4 + Piano Analytics / Amplitude + CRM + Data Warehouse.

How does our web analytics agency differentiate itself from other Analytics agencies?

EdgeAngel is neither a simple Google Analytics partner nor a pure media agency. As a web analytics agency, our approach combines 3 expertises:

Analytics & Web Tracking / Product Analytics / Server-Side
Marketing & Media Activation (Meta, Google Ads, LinkedIn, CRM...)
Data & AI (pipelines, DWH, reverse ETL, AI use cases)

This positioning allows us to connect web analytics to business rather than technique and quickly deploy ROI-generating actions.

How to know if my tracking is still reliable over time?

Tracking naturally degrades (redesigns, new features, tool updates...). That is why it is essential to have:

A data quality process (monitoring of events, conversions, anomalies)
QA environments
Clear governance between marketing, product, and tech teams

At EdgeAngel, we offer either RUN support (monthly + data quality) or a one-off project (audit, redesign).

What happens after tracking implementation?

Two possible options depending on your maturity:

➡️ One-shot project
Tracking redesign, GA4 migration, server-side deployment, GDPR compliance... then documented transfer to the internal team.

➡️ RUN support (most frequent)

Automated data quality
Technical support and tracking evolutions
Media / server-side flow optimization
Contribution to AI / marketing activation / CRO projects

Because robust tracking is never a one-off project: it evolves with the business.
