How to Install Google Tag Manager on Squarespace?

Why It Matters

Installing GTM on Squarespace centralizes tag management and enables flexible deployment of analytics and marketing pixels without editing site code, while preventing duplicate data by replacing native GA integration. This reduces implementation friction for marketers and improves tracking accuracy across tools.

Summary

This tutorial walks through installing Google Tag Manager (GTM) on a Squarespace site: create a GTM container, paste the primary container code into Squarespace’s Settings > Website > Pages > Code Injection header, and save. It then shows how to add a GA4 tag in GTM by copying your Measurement ID (or creating a Google Analytics property), testing via GTM Preview and Analytics Debug View, and publishing the container. The creator demonstrates removing Squarespace’s native Google Analytics integration to avoid duplicate tracking and publishing the GTM container so tags fire for all visitors. Finally, the video notes that full Analytics reports will populate within 24–48 hours.
