Digital marketing term
GTM
GTM (Google Tag Manager) is a tag management system that lets you deploy and update tracking tags on your site without hard-coding every change.
Detailed explanation
Google Tag Manager (GTM) sits between your website and marketing/analytics tools. You publish containers with tags, triggers, and variables so pixels, conversion events, and analytics scripts can be managed from one place.
In digital marketing, GTM is critical for clean measurement: conversion tracking, remarketing pixels, and event instrumentation. Poor GTM setup leads to missing or duplicate data, which makes CTR, CPA, and ROAS decisions unreliable.
