Google Tag Manager

Google Tag Manager (GTM) is a system for managing tracking codes on websites. It is provided by Google and the principle of its operation is that only one code is placed on the website and the insertion of individual measurement codes then takes place via the GTM user interface. As a result, it will make it easier and faster to work with codes (tags), and their deployment does not have to be performed by programmers. The advantage is the possibility not to have to deal with technical aspects and instead focus on the measurement itself.
