Fastr Workspace - Installing the Fastr Optimize Tag – Fastr Community

Overview

Fastr Optimize surfaces where your site leaks revenue and powers the experiments that drive lift. It's delivered as two JavaScript tags, each installed site-wide:

Analytics tag — captures every visitor interaction across your site, giving you a complete picture of engagement and performance.
Experiments tag — runs A/B tests and personalization across your site without code changes.

Your CSM will send you the tag (or both) that matches your plan. This article walks through installing each one — follow only the section(s) for the tag(s) you received.

Before you start

You'll receive each tag from your account manager. Tags are also available later in your Workspace account under team settings (admin access required), and look like this:

Installing the Analytics tag

You can install the Analytics tag two ways. Pick whichever fits your stack — you only need to do one.

Method 1: Add the tag directly to your site's `<head>`

Paste the embed code in your <head>, just before the closing </head> tag, on every page of your site (or in your site template if you use a CMS or framework). Loading in <head> lets the tag run early in the page lifecycle and capture accurate timing, engagement, and navigation data across your entire domain.

Method 2: Install via Google Tag Manager

In Google Tag Manager, go to Tags → New.
Choose Custom HTML Tag.
Paste your tag into the HTML field.
Under Triggering, select All Pages so the tag fires site-wide.
Save and Publish your container.

Installing the Experiments tag

Paste the embed code in your <head>, just before the closing </head> tag, on every page of your site (or in your site template).

The Experiments tag must be installed directly in <head> rather than through Google Tag Manager. It needs to run before the page renders so it can swap content without a visible flicker — something GTM can't reliably guarantee.

Installing both tags

If your CSM sent you both, complete both sections above. Order doesn't matter, and both tags can live in <head> together.

Let us know when you're done

Once your tag(s) are in place:
