Whether a company is selling product through a website, is posting scholarly case studies or even news articles, they need to know what their consumers are actually doing on their site. Are they getting to the homepage and leaving? How about adding products to their cart but not purchasing them? Or are they reading half of an article or watching half of a video and calling it quits? All of these things can be tracked with the help of Google Tag Manager.
Google Tag Manager essentially cuts the corners of coding, allowing easier use for the common user. In this video provided: https://youtu.be/9A-i7EWXzjs, if you watch from 1:40-2:10, Krista Seiden, Analytics Advocate at Google, explains the steps taken to provide ease of use. As long as the user has a general idea of what event they want to track, google provides tag templates and walk through processes to create triggers for each separate event. They can also break each event into subcategories and they can track multiple different sets of data.
For example: if a product has a long description that forces users to scroll down on the page, Tag Manager allows you to track whether the user just viewed the product, added it to their cart and didn’t purchase it, if they scrolled down to read the description and then purchased the product. The main benefit to Tag Manager is the many different options for data collection that allows a wide variety of websites to use it to collect whatever information they may need.
