Google Analytics tracks and stores data related to website activity, such as the number of people who visited your website in the last 30 days, the number of pages visited per session, or the number of visitors that bounced off of your website. It uses a single Javascript code snippet that gets placed on every page of your website. On the other hand, Google Tag Manager allows users to track how many people use specific features on your website or application, such as placing an order or completing a form. In this case, an additional tracking tag gets generated. Google Tag Manager allows users to deploy hundreds of tags on a single site, such as event codes, remarketing tags, and conversion scripts. From there, Google Tag Manager allows users to store and view all tag activity in one place. It is a welcome alternate to hard-coding tags on individual pages.
