Google Tag Manager (GTM) is a free tag management system provided by Google that allows you to manage and implement tracking and marketing tags on your website or mobile app without requiring changes to the underlying code. It provides a user-friendly interface for managing tags, including tags for Google Analytics, AdWords, Floodlight, and many others.

With GTM, you can add, edit, and manage all your tags from a single interface, making it easy to keep your tracking and marketing efforts organized and up-to-date. This eliminates the need for a developer to make changes to your website or app every time you want to add or update a tag. Instead, you can do it yourself, without any coding knowledge required.

How is GTM useful?

Google Tag Manager reduces the time for developers by:

• Eliminating the hassles of creating codes 
• Pushing the control into the hands of Marketing teams
• Centralizing tag management into a single platform
• Reduces human error
• Seamlessly work with Google Analytics
• Can track everything like Brochure download, page views etc
• Simplifies the process of adding new tags & triggers
• Instant check if new tags are firing on the website
• Makes advanced tracking a breeze 
• Boost website speed

Google Tag Manager is free, so organizations or business owners don’t need to hire developers to do the work & thereby reduces cost.
