Marketing Attribution - signals that survive iOS and ad blockers.

Client-side pixels alone no longer tell the full story. iOS 14.5+, Safari ITP, and ad blockers are silently stripping conversion data from Meta, Google Ads, and TikTok - degrading match quality and making campaign optimisation harder every year. Server-side integration closes that gap.

Why It Matters

Signs your ad platform data needs attention.

These are the most common attribution problems we find - most invisible until match quality or ROAS reporting starts slipping.

Client-side pixels missing a growing share of conversions

iOS 14.5+, Safari ITP, and ad blockers collectively strip a significant portion of conversion events before they ever reach Meta or Google. The gap grows every year as browser restrictions tighten.

✓ Server-side APIs recover conversions client-side pixels miss

Poor match quality hurting campaign optimisation

Meta and Google Ads optimise campaigns based on how confidently they can match a conversion to a real user. Weak match quality means the algorithm is optimising on incomplete signal - and your CPAs show it.

✓ Enriched, hashed first-party data improves match quality scores

Duplicate conversions from running pixel and API together

Adding server-side tracking without proper deduplication means the same conversion gets counted twice - inflating your numbers and making campaign performance look better (or worse) than reality.

✓ Event ID-based deduplication keeps counts accurate

Cannot prove ROAS to leadership with confidence

When attribution data is inconsistent between platforms and your own analytics, it becomes difficult to make a confident case for ad spend - even when campaigns are actually performing well.

✓ Consistent, validated data across all platforms and GA4

What We Do

Everything we cover in a server-side attribution build.

We implement server-side conversion tracking across the ad platforms that matter to your business - built to complement your existing client-side pixels, not replace them blindly.

Meta Conversions API implementation with proper event matching (hashed email, phone, external_id)
Google Ads Enhanced Conversions setup for both web and offline conversion imports
TikTok Events API integration where relevant to your media mix
Event deduplication between client-side pixel and server-side API using event_id
Server-side enrichment of conversion events with first-party customer data
Full validation of match quality and event delivery in each platform's testing tools

What You Get

Server-side conversion tracking across your ad platforms
Improved match quality scores
Deduplicated, accurate conversion counts
Platform-side event testing validation reports
Documentation of what is sent to each platform and why
30-day post-launch support

Our Process

How we approach every attribution engagement.

Audit & Platform Mapping

We review your current pixel setup across every ad platform in use, identify where server-side coverage is missing, and map exactly which conversions need it most.

Server-Side Implementation

We build the CAPI, Enhanced Conversions, and Events API integrations with proper data hashing, event deduplication, and first-party data enrichment - coordinated with your existing GTM/sGTM setup.

QA & Validation

Every event validated in Meta Events Manager, Google Ads diagnostics, and TikTok Events Manager. Match quality improvements confirmed before we call it done.

FAQ

Common questions about server-side attribution.

What is the difference between client-side and server-side conversion tracking?

Client-side tracking (a pixel in the browser) sends conversion data directly from the user's device - which browsers, ad blockers, and privacy restrictions can block or strip. Server-side tracking sends the same conversion data from your own server, which is far more resilient to those restrictions and generally includes richer, more accurate data.

Do we need this if we already have GTM and a Meta pixel installed?

Yes, if you want reliable data. A client-side pixel alone is increasingly incomplete - server-side tracking runs alongside it, not instead of it, recovering the conversions the pixel misses and improving the accuracy of what both report.

How does this help with iOS 14.5+ restrictions specifically?

iOS 14.5+ and Safari ITP restrict tracking that relies on browser cookies and client-side scripts. Server-side APIs bypass much of this by sending conversion data directly from your server using hashed first-party data instead - data the browser cannot block.

Will this cause duplicate conversions in our ad platforms?

Not if implemented correctly. We use event ID-based deduplication, which tells the platform that a client-side and server-side event represent the same real conversion, so it is only counted once.

Do you work with platforms beyond Meta and Google Ads?

Yes - TikTok Events API is common, and we can scope other platforms (Pinterest, Snapchat, LinkedIn) depending on your media mix during the audit phase.
