GTM + GA4 Implementation · Event Tracking · Funnel Insights · Mobile Optimization

PromptPal is a demo-stage product site built to validate user interest before a full launch. I implemented end-to-end conversion tracking using GTM + GA4 to measure two outcomes: how many visitors signed up for early access, and how many engaged with the demo experience.

Analysis revealed a significant mobile drop-off at the landing page; mobile users were completing the demo CTA click at just 37.5% vs. 100% for desktop. A UX audit identified a misaligned CTA button on mobile as the likely cause. After repositioning the button, mobile demo engagement jumped from 37.5% to 66.67%, and mobile completion through the full demo flow reached 100%. The most meaningful and consistent improvement post-fix was in demo activation, not signup, which is where the clearest signal was expected, given the nature of the change.

Project Overview

The goal of this project was to implement conversion tracking for PromptPal using GTM + GA4, then use the resulting data to identify friction in the user journey and make an evidence-based improvement.

Two primary outcomes were measured:

  1. How many visitors sign up for early access?
  2. How many visitors click into and complete the demo experience?

Product Context

PromptPal is a self-built demo site designed to test product-market interest before committing to a full build. At this stage, the site is not selling a finished product; it is validating whether real users show enough intent to sign up or engage with a simulated version of the experience.

Intended User Journey

Visitors arrive at the landing page and can take either or both of the following actions independently:

  1. Sign up for early access — submit their email to join a waitlist
  2. Try the PromptPal demo — enter the demo experience to simulate product use
