GTM

Google Tag Manager

Tag deployment system -- manage tracking pixels without code pushes.

When you'd see it: Marketing and web-analytics setups. Google Tag Manager is the tool that manages tracking tags (Google Analytics, ad pixels, conversion tags) on a site without editing code for each change.

Why it matters: It lets marketers add and change tracking tags themselves, decoupling analytics changes from engineering releases. It shares its acronym with Go-to-Market, which is a completely different concept.

Common mistakes: Confusing it with Go-to-Market strategy. They share the acronym GTM and nothing else.
