We need a developer to audit, diagnose, and ensure correct UTM tracking and GA4 attribution.
Current Environment • WordPress (IONOS Managed WordPress hosting) • Site Kit by Google (GA4 connected) • GA4 Measurement ID active • Server-side caching previously active (IONOS Performance Level) • No Cloudflare • No MonsterInsights • No Complianz (currently deactivated) • Previously had a plugin stripping UTMs via JavaScript (now removed)
Problems We Experienced
1. UTMs were previously being stripped from the URL via a JS file: /wp-content/plugins/wp-stats-manager/js/wsm_new.js (plugin now removed and cache flushed) 2. After resolving URL stripping: • GA4 does not consistently attribute session source/medium correctly. • In some tests, no g/collect requests fire. • Sessions sometimes appear as (direct) / (none) despite valid UTMs. • Realtime reporting is inconsistent. 3. Behaviour has varied between devices (likely due to server-side caching).
Infrastructure has been partially cleaned up, but we need a full technical audit and clean implementation.
What We Need Done
1. GA4 Audit & Correction • Confirm only one GA implementation is loading. • Confirm page_view is firing correctly. • Confirm g/collect requests include: • campaign source • campaign medium • campaign name • Ensure UTMs are captured on first page load (new session). • Confirm no duplicate tags or container conflicts.
We are open to: • Removing Site Kit • Implementing clean manual GA4 (gtag.js) • Or implementing via GTM if preferable
2. JavaScript Review • Confirm no scripts are: • Calling history.replaceState • Cleaning query strings • Removing UTM parameters • Confirm no theme-level or plugin-level URL manipulation.
3. Caching Review • Confirm no server-side full page caching is serving stale HTML. • Confirm no service worker is registered. • Ensure consistent behaviour across devices/IPs.
4. Final Verification
Provide proof that: • Fresh private session with UTM URL • Correct attribution appears in GA4: • Session source • Session medium • Session campaign • Realtime and Acquisition reports reflect correct traffic source.
End Goal
We need fully reliable attribution for:

This is critical for measuring direct mail ROI.
Requirements • Strong GA4 debugging experience • WordPress experience • Familiarity with IONOS hosting • Comfortable using DevTools and network inspection • Ability to explain findings clearly
Deliverables
• Clean, working GA4 attribution • Clear explanation of what was wrong • Confirmation that infrastructure is stable • Recommendation for simplified tracking stack (if needed)
