Case Study: ENGIE achieves faster customer acquisition and major tagging cost and time savings with Commanders Act

ENGIE harnesses TagCommander to drive digital performance

ENGIE, a global energy group with a consumer site attracting about 1.4 million unique visitors a month, needed to redesign its site to meet evolving digital demand: improve user experience for key moments (like moving home), capture prospects comparing tariffs, identify customers at risk of churn, and reliably measure and attribute performance across affiliate and retargeting channels while reducing tagging costs and lead times.

ENGIE implemented Commanders Act (TagCommander + Privacy) and a detailed tagging plan covering 950 measurable elements across 275 pages, centralizing data for multi-touch attribution, lead deduplication and CRM correlation. The change cut tagging lead times from weeks to days, saved an estimated 3–5 months of effort per year, improved tag coverage and data reliability, and enabled the team to manage many new e-marketing partners in-house.
