Server-side tracking has been the right solution to iOS/adblocker data loss for years. Our problem: setting it up properly requires a GTM server container, a separate cloud instance, correct trigger configuration, and a developer who knows what they're doing. Most WordPress sites never get there.

We manage tracking for 12 websites hightraffic sites at the agency i work (combined 3.9M monthly search impressions, ~370K sessions/month). After rebuilding our entire tracking stack server-side, we packaged the setup into a WordPress plugin.

How it works: - Plugin intercepts GA4/Ads/Meta events before they hit the browser - Routes them through your server to Google and Meta endpoints directly - No client-side JS dependency for conversion data

The result: we recovered 25–35% of conversion events that were previously lost to ad blockers and consent banner dismissals. So more and better data.

Technical notes: - Works alongside existing GTM web containers - Supports GA4 Measurement Protocol + Meta Conversions API - WordPress plugin, self-hosted, no third-party relay

Curious to hear what the HN crowd thinks about the server-side tracking space in general.
