Example
Reload Mode installs GTM on client sites so the marketing team can add Hotjar, Meta Pixel, and LinkedIn Insight Tag without touching the site's code.
Google Tag Manager is used on over 28 million websites and is installed on approximately 44% of the top 1 million websites globally — making it the dominant tag management solution, according to W3Techs.
What it applies to
Any website that uses more than one tracking or marketing script — analytics, advertising pixels, heat-mapping tools, chat widgets, or conversion tracking. GTM centralises deployment and removes dependency on development for tag changes.
How to set up Google Tag Manager
- Create a GTM account at tagmanager.google.com and create a Container for your website.
- GTM provides two code snippets — one for the <head> and one for the <body>. Add both to every page of the site.
- In Webflow: add the <head> snippet to Project Settings → Custom Code → Head Code, and the <body> snippet to the Body Code field.
- Inside GTM, create Tags (the scripts to run), Triggers (when to fire them), and Variables (dynamic values like page URL or click text).
- Preview and debug in GTM's Preview mode before publishing — it shows exactly which tags fire on each page and why.
Essential tags to deploy via GTM
- GA4 Configuration tag — fires on all pages
- GA4 Event tags — for form submissions, CTA clicks, scroll depth
- Meta Pixel — fires on all pages with custom events on conversions
- LinkedIn Insight Tag — for B2B ad conversion tracking
- Hotjar or Microsoft Clarity — for heatmaps and session recording
