Google Tag Manager

Google Tag Manager (GTM) is a free tag management system from Google that lets you deploy and manage marketing and analytics tags on a website or application without modifying source code. Tags can include Google Analytics tracking, Facebook Pixel, conversion pixels, remarketing scripts, and custom event trackers, all controlled from a single web-based interface.

Without GTM, adding or changing tracking code requires a developer to edit and redeploy your site every time. GTM removes that bottleneck, letting marketers add, update, or remove tags in minutes. This speeds up campaign launches, reduces the risk of broken code, and keeps all tracking logic in one auditable place.

FlipLink supports [tracking pixels](/features/tracking-pixels) including GTM container scripts. You can paste your GTM container ID into your flipbook or document settings, and FlipLink injects the script into the viewer. Once GTM is active, any tags you configure inside your GTM workspace — Google Analytics, Facebook Pixel, LinkedIn Insight, or custom HTML tags — fire automatically when readers interact with your publication. This gives you full control over tracking without touching FlipLink's publishing workflow.

A marketing team adds their GTM container to a product catalog flipbook. Through GTM, they deploy a Google Analytics tag for page views, a Facebook Pixel for retargeting, and a custom event tag that fires when a reader clicks the "Request a Quote" CTA button — all without any code changes to the flipbook itself.
