"GTM" can refer to several things depending on the context.
Here are
the most common meanings:
1. Google Tag Manager (GTM)
Most common usage in digital marketing and web
development.
     What it is: A free tool by Google that allows marketers and
      developers to manage and deploy marketing tags (snippets of
      code or tracking pixels) on a website or mobile app without
      modifying the code directly.
     Key Benefits:
        o   Centralized tag management (e.g., Google Analytics,
            Facebook Pixel, conversion tracking).
        o   No need for a developer every time you want to add or
            update a tag.
        o   Built-in debugging tools and version control.
     How it works:
        o   You install the GTM container snippet on your site.
        o   Inside GTM, you create "tags" (e.g., for GA4), define
            "triggers" (when they fire), and use "variables" (to pass
            data).
     Common use cases:
        o   Event tracking (e.g., clicks, form submissions)
        o   A/B testing scripts
        o   Custom HTML or JavaScript injections
2. Go-To-Market (GTM) Strategy
Business and product management context.
     What it is: A plan that outlines how a company will launch a
      product or service to the market.
     Key Elements:
        o   Target audience
        o   Value proposition
        o   Sales and marketing strategy
        o   Distribution channels
        o   Pricing model
     Goal: Ensure a smooth product launch and maximize adoption,
      revenue, and market penetration.
3. Greenwich Time Mean (GMT) (Sometimes miswritten as
GTM)
     If you meant GMT (not GTM), it stands for Greenwich Mean
      Time, the time at the Royal Observatory in Greenwich, London,
      used as a global time standard.
