In brief (Summary for the busy):
The Client: SunStyle, a leader in solar tiles (High-Ticket B2B/B2C).
The Problem: Compliance (CMP Complianz on WordPress) blinded the Ads campaigns (-35% data).
The Solution: A hybrid architecture of Server-Side Tracking + HubSpot API (CRM).
The Results (1 year): Data reliability at 99%, CPA reduced by CHF 33.- and +312 conversions generated.
1. The Context: When Compliance Breaks Performance
SunStyle sells cutting-edge technology: aesthetic solar roofs. The sales cycle is long, the average basket is high, and each lead is worth gold.
Their site, powered by WordPress, had to comply strictly with the nFADP and GDPR. The team deployed the cookie management solution Complianz.
The immediate shock: As soon as the cookie banner was activated, the dashboards went dark.
Between cookie refusals, AdBlockers, and browser restrictions (ITP), the gap between actual leads (in the CRM) and visible leads (in Google Ads) rose to 35%.
Consequence: The Google Ads algorithm, deprived of a third of the data, began to poorly optimize bids. The cost per lead increased.
This is where A-Track intervened.
2. Phase 1: The Urgency of Server-Side Tracking
Our first intervention was to keep our head above water. We could no longer rely solely on the client's browser (Client-Side), which is vulnerable to blockers.
We deployed a GTM Server-Side infrastructure. Instead of sending data from the visitor's browser, we routed it through a secure server controlled by SunStyle.
Intermediate result: The data gap decreased from 35% to 12%. It was better, but for an industrial player like SunStyle, losing still 1 lead out of 10 remained unacceptable for budget management. Perfection was the goal.
