Multi-Platform Conversion Tracking

One source of truth, feeding every platform you’re spending on. Deduplicated, consented, and accurate.

If your ad spend is split across platforms, your tracking has to keep up — but the platforms don’t make it easy. Each one has its own pixel, its own server-side API, its own quirks around customer data hashing, deduplication and consent.

I set up multi-platform tracking that gets the cleanest possible signal to every platform - without double-counting, without breaking attribution, and without leaving you exposed on consent.

Platforms I cover.

Meta (Facebook & Instagram)

  • Meta Pixel base implementation

  • Standard events: PageView, ViewContent, AddToCart, InitiateCheckout, Purchase, Lead, CompleteRegistration

  • Meta Conversions API (CAPI) — server-to-server event sending

  • Deduplication between Pixel and CAPI (essential, often missed)

  • Advanced Matching with hashed customer data

  • Catalogue / dynamic ads event configuration

  • Consent integration with Consent Mode and your CMP

Microsoft Advertising (Bing)

  • Microsoft UET tag base

  • Custom events and goal configuration

  • Enhanced Conversions for Microsoft

  • Bing product ID mapping for shopping campaigns

TikTok

  • TikTok Pixel base implementation

  • TikTok Events API (server-side event sending)

  • Standard events: PageView, ViewContent, AddToCart, InitiateCheckout, CompletePayment, SubmitForm

  • Identity matching and deduplication between Pixel and Events API

  • Consent-aware firing

LinkedIn

  • LinkedIn Insight Tag

  • Conversions API for LinkedIn (where available)

  • B2B-specific event configuration tied to lead-gen pipeline stages

Google Ads

  • Conversion action setup - calls, leads, purchases, custom

  • Enhanced Conversions for Web and for Leads (with hashed first-party data)

  • Cross-account / MCC structures

  • Conversion linking with GA4 for import-based reporting

  • Consent Mode v2 integration

Additional Platforms

  • Pinterest - Pinterest Tag + Conversions API, Enhanced Match

  • Snapchat - Snap Pixel + Conversions API

  • Reddit - Reddit Pixel + Conversions API

  • X (Twitter) - X Pixel + Conversions API

  • Outbrain / Taboola - native ad pixels and conversion APIs

  • Spotify Ad Analytics

  • CRM systems

Why it matters now.

Apple’s iOS privacy changes, Safari ITP, Firefox third-party cookie blocking and the prevalence of ad-blockers mean that between 20% and 40% of your conversion signal can be lost on a typical client-side setup. Every major platform has responded by building server-side APIs - Conversions API, Events API, Enhanced Conversions. Using them properly is no longer optional if you want competitive match rates and accurate attribution.

I set up the client-side pixels, the server-side APIs, the deduplication logic and the consent gating, so each platform gets the cleanest possible signal, and you’re not double-counting in one place while under-counting in another.

How it works.

1. Audit

I review what you already have - pixels in place, server-side APIs configured or missing, deduplication logic, consent gating. I’ll come back with what’s working, what isn’t, and what to do about it.

2. Build

Pixels, server-side APIs, deduplication, Advanced Matching, consent gating. Configured per platform, tested as I go.

3. Validate

Match rates checked in each platform’s event manager. Deduplication confirmed. Consent states tested. Live transaction or lead walkthroughs end to end.

4. Document & handover

Documentation of what’s firing where, deduplication keys, hashed data fields and any platform-specific quirks. So when match rates drop in six months’ time, you can see why.

This is for you if...

  • You’re spending on two or more ad platforms

  • Match rates on Meta or TikTok have dropped or never been good

  • You’re still on Pixel-only and haven’t set up Conversions API or Events API

  • Attribution looks shaky after iOS, Safari or Firefox privacy changes

  • You’ve never actually confirmed that your Pixel and CAPI events aren’t double-counting

  • You need cross-platform reporting that actually reconciles back to your sales or CRM data
