Marketing wants GTM, but nobody fully understands it.
Google Tag Manager is a container managing tags (analytics, pixels, custom scripts) without code changes. Powerful, but without discipline a sprinkle box.
Try this first
- 1Create a GTM account for the company and a container per site. Place both snippets (head and body-start) on every page.
- 2Move the GA4 tag from direct theme snippets to GTM. Centralised control and you can apply consent mode via GTM.
- 3Standard tags that belong in GTM: GA4, Google Ads, Meta Pixel, LinkedIn Insight, any heatmap (Hotjar).
- 4Triggers: use built-ins (Page View, Click, Form Submit) where possible. Custom triggers via dataLayer events.
- 5Test every change in Preview mode. Publish via versioned releases with brief notes. Name versions meaningfully.
- 6Agree who publishes, who tests, who reviews. Without process everyone adds tags and you'll inherit a mess in a year.
