Key Results
Tracking script captures all 5 UTMs and 8 ad click IDs; attribution tested across 6 traffic sources; Google, Reddit and TikTok integrations live
The Challenge
The agency had a half-built attribution CRM on Replit with no working tracking script, the piece that makes attribution possible at all. It had to capture every UTM and ad click ID, work in single-page apps, respect privacy, and tie conversions back to campaigns on every major ad platform.
Our Solution
We moved the app from Replit to GitHub and wrote the tracking script from scratch: single-page-app pageviews, first-party visitor and session IDs, client-side SHA-256 hashing of emails and phone numbers, sendBeacon delivery with batching and retries, first- and last-touch persistence, purchase de-duplication and a public track/identify API. It captures all five UTM parameters and eight click IDs (gclid, wbraid, gbraid, fbclid, ttclid, msclkid, li_fat_id, twclid). We redesigned attribution as channel → campaign → ad → events, added automatic conversions from CRM deals and contacts, and built OAuth integrations for Meta, Google Ads, LinkedIn, Reddit and TikTok.
The Outcome
Attribution has been tested across six traffic sources, and the platform now runs on Cloudflare Workers with the Google, Reddit and TikTok integrations live. Cross-domain tracking is in live testing, and consent mode for EU, US and global traffic is in progress.
Highlights
- First-party tracking script written from scratch
