<h2>How to Implement Customer.io Tracking on WordPress with Server-Side Tagging</h2><p>Traditional client-side tracking on WordPress is becoming increasingly unreliable. Privacy-focused updates like Apple’s ITP, widespread use of adblockers, and stricter cookie policies have made it difficult to accurately measure conversions and user behavior. For marketers using Customer.io on WordPress, this results in incomplete data and missed revenue opportunities.</p><p>The solution? Moving your Customer.io tracking to a server-side setup, which ensures significantly better data accuracy and long-term reliability.</p><p>Server-side tracking routes data through a controlled server environment rather than relying on the user’s browser. This approach drastically reduces data loss caused by browser limitations and adblockers. Pairing server-side tagging with Google Tag Manager and tools like Stape.io gives you precision control, improved page performance, and far better data persistence.</p><p>For brands using Customer.io on WordPress, a server-side implementation means higher attribution accuracy. We often see a 20–30% increase in measured conversions after migrating to server-side tracking—especially when paired with Meta’s Conversions API and Enhanced Conversions for Google Ads.</p><p>At Obsidian Digital, we've completed more than 200 server-side tracking setups for leading brands including Rains, Day-et, Eyda and Onyx Cookware.
