Tag manager
A tracking code is a small piece of code that collects data about how people use your website — like which pages they visit or what buttons they click. Normally, adding these tracking codes requires a developer to modify the website. This is where tag managers come in to make life easier.
Google Tag Manager works like a container that holds all your tracking codes in one place. Instead of asking developers to add different codes for tools like Google Analytics, Facebook Pixel, or other tracking tools, you only need them to add the tag manager code once. Once installed, non-technical team members can add or update tracking through a simple dashboard without touching the website code. It's like having a control panel where you can turn different tracking on and off as needed.[1]
