VERDICT

Should I use Google Tag Manager?

Free tag management for deploying marketing and analytics tags without code releases - tagmanager.google.com

Worth it. Buy if you run more than one marketing or analytics tag — it's free and the de facto standard. Skip it if you only need a single pixel or have no one to own container governance.

Best for

  • Privacy-strict EU orgs wanting self-hosted control
  • Non-technical owners expecting set-and-forget

Gotchas - check before you buy

high

Container access equals script-injection rights; compromised containers are used for card skimming

high

Unmanaged legacy tags accumulate silently, creating security and performance debt

medium

Free version costs nothing, but GTM 360 pricing is sales-quoted and opaque

medium

Free support is community forums; reported issues can sit unresolved
