Google Tag Manager (also known as GTM) is the ideal tool to collect all the data needed to track and improve your marketing.
If you use Google Analytics (or another web analytics tool), you already gather certain data: number of page views, bounce rate, average length of visits, traffic sources, etc.
Although very useful, this information quickly reaches its limit. Using Google Tag Manager, you can gather more. For example:
The top selling products and categories and the revenue generated;
Registrations to your newsletter
Clicks on a given product
Downloads of a document (PDF, etc.);
Clicks on "add to cart";
Products removed from the basket;
Discount coupons use;
Navigation depth on the page;
Triggering and play time of a video.
In general, if you want to get this type of data in Google Analytics, it requires the intervention of a web developer.
Fortunately, Google Tag Manager lets you collect all this information with tracking tags. These tags simply tell Google Tag Manager what data to collect.
