Benefits of using GTM:

  • Website speed of working will increase.
  • No more dependency on developer will be required.
  • Another benefit is when you work for big agency you usually don’t have access to server in that case you tend to connect with agency manager who again connects with its developer who puts the code on server which at last is verified by you. So, in short it involves a big and complicated process which is removed easily by the use of Google Tag Manager.

Disadvantage of not using GTM:
