Server-Side GTM Setup – Part 3 – Additional Tags & Testing

In this server-side tagging tutorial, I'll show you how to test your Google Tag Manager setup and optimize it for better data accuracy. To make server-side tagging simple to set up and manage, I recommend using Stape. Get started with Stape at https://lnk.stape.io/LovesData_June We'll verify that data is flowing correctly from your website through your server-side container to Google Analytics and Google Ads, then adjust your web container to prevent duplicate tags. Finally, we'll set up Stape's Custom Loader to improve tracking reliability and reduce the impact of ad blockers. This video focuses on three critical steps: testing your server-side implementation to verify data is flowing correctly, eliminating duplicate tags that can distort your reports, and implementing Stape's Custom Loader to improve tracking reliability for all visitors, including those with ad blockers. By the end of this video, you'll have a fully tested and optimized server-side setup live on your website. This video is sponsored by Stape, a managed hosting solution for Google Tag Manager server-side containers that makes it simple to set up and manage server-side tracking without building your own infrastructure.
