Next.js presents unique challenges for GTM and data layer implementation: server-side rendering, client-side hydration, and App Router layouts require careful handling to avoid double-firing, hydration mismatches, and missed events. We implement a Next.js data layer using the correct patterns for your version (Pages Router or App Router), script loading strategies, and route change detection — ensuring accurate, reliable event tracking without affecting Core Web Vitals.

This happens when both server-rendered HTML and client-side navigation both trigger pageview events. We implement deduplication logic to prevent this.
Yes — Next.js's third-party library provides a GTM component that we can work with, extending it with custom data layer events.
