• Quick events’ tracking on the website. In a minute, generate and configure codes to track external links, button clicks, the number of submitted forms and more. 
• Accelerating website work. Tag loading is gradual, activating one does not slow down the launch of others.

In which cases will Google Tag Manager bring the most benefit

• You use several analytics services, and attract many third-party services to the website as well. 
• You do not have a full-time developer. 
• It is important for you to record any users’ interactions with the website: scrolling, submitting forms, clicking buttons, transitions between website’s pages. 
• You track and analyze different KPIs. 
• You conduct A/B testing and actively launch remarketing. 
• You are involved in several projects at the same time.

Tag manager works on the principle of chain reaction. That means that performing a certain action with the specified parameters triggers a tag, which, in fact, sends you data for analysis.

Obtained data is imported into one of the analytics services, such as Google Analytics. This will allow you to analyze advertising campaigns, test individual elements on the website, and as a result — adjust promotion strategy of your brand.
