FAQ

GTM makes it easy to track conversions, integrate third-party tools, perform analyses and optimize marketing campaigns. It centralizes tag management, reducing errors and accelerating the deployment of updates.

Yes, GTM comes with advanced security features. You can control access authorizations, validate and test tags before deployment, and easily roll back tags if necessary.

This depends on the complexity of your site and your monitoring requirements. In most cases, the initial set-up can be completed in a few days, followed by a phase of ongoing optimization.

At Mangrovea, we follow the best practices recommended by Google. We also test all tags in a pre-production environment before deploying them live.
Yes, we offer training sessions for all levels, from beginner to expert, to help you get the most out of GTM.

It delivers better performance, reduces reliance on third-party cookies (often blocked by browsers), improves data confidentiality and offers greater flexibility in tag management.
