In Brief: The Results (Comparison 2023-2026 vs 2021-2023)

  • Cost per Lead (CPL): -51% (decreasing from CHF 68.- to CHF 33.-).

  • Conversion Volume: +302% (Qualified leads tripled).

  • The Challenge: An ultra-sensitive B2B audience with 48.5% tracking refusal.


1. The Paradox of the Fiduciary

For a fiduciary like G. Salerno & Associates, trust is the currency of exchange. Their clients are entrepreneurs and companies that demand total discretion.

On the web, this translates into very specific behavior: The massive refusal to be tracked. The statistics from their tracking server (Stape) are undeniable:

  • 48.52% of visitors refuse statistical cookies (Opt-out) on the homepage.

  • 19.72% use secure browsers (Safari, Firefox) that naturally limit tracking.

The Deadlock: With a classic setup (standard Google Analytics), the fiduciary was blind to more than half of its traffic. It was impossible to optimize Google Ads campaigns when 1 in 2 leads was invisible. The cost per acquisition (CPL) stagnated at CHF 68.-, a high amount even for B2B.

2. The Solution: Maximum Security & Modeling

To break this deadlock without compromising ethical confidentiality, A-Track deployed a strict

Questions fréquemment posées

B2B Lead Gen: How to track lead quality?

You should not only track the form submission. You need to use Server-Side to send an "Offline Event" to Google/Facebook when the lead becomes a "qualified" or "signed" client in your CRM.

Is Server-Side tracking reserved for large companies?

No. With solutions like Stape, it has become accessible to SMEs. It is even recommended for any e-commerce generating more than 20-30k CHF in annual revenue to secure its data.

Does Server-Side tracking improve SEO?

Indirectly, yes. By moving the execution of scripts (Facebook Pixel, Hotjar, etc.) from the browser to the server, you lighten the page's code. The site loads faster, which is a positive ranking factor for Google (Core Web Vitals).

Why use server-side tracking for LinkedIn Ads?

Server-side tracking bypasses browser limits, ad blockers, and cookie blocking, providing more reliable data and allowing LinkedIn to optimize your campaigns more effectively. With A-Track, this data is processed and hosted in Switzerland, in full compliance with the nFADP and GDPR.

What is "Server-Side" tracking?

It is a method where the browser sends data to your intermediary server (proxy), which cleans it and then forwards it to the platforms. You maintain full control of the data before it goes to the GAFAM.

What is the monthly cost of a Server-Side infrastructure?

With Stape, it starts around 20-30 CHF/month for a standard site, compared to often over 100-150 CHF/month on Google Cloud for equivalent performance.

What are the major advantages of Server-Side?

Bypassing AdBlockers.

Extension of cookie lifespan (bypassing Safari ITP).

Data protection (anonymization before sending).

Improvement of site loading speed (fewer scripts in the browser).
