Improving accuracy of website analytics for HSE Network

Boosting data accuracy with server-side tracking

“Our member data is our most critical business asset. Implementing GA4, BigQuery, and server-side tracking with Varn eliminated our data blind spots overnight. Capturing that hidden data delivered immediate commercial value; significantly expanding our ad capacity and boosting content performance. It paid for itself straight away.”

Measuring the impact of server-side implementation

HSE Network is the largest organic health and safety publisher combining thought leadership, coverage of occupational health and safety news and content that can inform EHS strategy and keep businesses up to speed with the latest best practices.

To enhance HSE’s reporting accuracy and resolve data gaps, we designed a server-side tracking and BigQuery solution. Following a data audit, we discovered that standard client-side GA4 was failing to capture almost 30% of sign-ups when comparing the data directly to the CRM. With precise conversion tracking becoming our primary focus, we shifted their setup to a server-side environment.

To build a highly reliable reporting framework with absolute transparency, we compared the conversions in BigQuery against the exact moments recorded in their CRM, highlighting a dramatic reduction in data loss, with the new setup now capturing 94% of leads.

We saw an uplift in other metrics, such as page views and total users, which both recorded a 21% increase in server-side reporting.
Overall sessions also showed a 19% increase.

To accurately validate the impact server-side tracking had, we ran a simultaneous client-side GTM setup on the site and directly compared the results.

Server-side data precision & BigQuery integration

By migrating from browser-dependent tags to a server-side environment, we gave HSE an authoritative, single source of truth for their analytics. Replacing native GA4 estimation with granular BigQuery logging eliminated critical blind spots, resolved plugin discrepancies, and restored complete confidence in their conversion reporting.

To deliver this level of precision, we built a modern analytics flow around Server-Side Google Tag Manager (sGTM), Stape.io and Google BigQuery. By decoupling event collection from the user’s browser and routing data through a secure cloud server, we bypassed native GA4 API throttles and processing limits. This allowed us to feed raw, un-sampled event-level data straight into BigQuery, where it could be seamlessly cross-referenced and validated against HSE Network’s CRM.
