What is a core benefit of using Google Tag Manager instead of manual tagging?

• A. It automatically eliminates all code changes
• B. It eliminates the need to configure analytics
• C. It centralizes tag deployment and reduces direct edits to page code
• D. It doubles page load time

Answer: (C)

Centralizing tag deployment and reducing direct edits to page code is the main advantage. Google Tag Manager lets you manage a container with all tags, triggers, and variables, so you can add or update analytics and other tracking without touching the site's HTML on every page. You publish changes once and they apply across the site, and you can test them in preview before going live. This makes maintenance easier, speeds updates, and reduces the risk of breaking pages because you’re not editing the code directly each time. Analytics configuration still happens, but inside GTM rather than by dropping new snippets on every page. GTM loads tags asynchronously, so it doesn’t inherently double page load time.
