Learn moreThe Real Problem
Where is your tracking breaking down?
When conversion tracking isn't reliable, ad platforms optimize for the wrong signals, reported ROAS is distorted, and scaling decisions become risky guesswork.
PROBLEM 01
Missing Conversions
Browser ad-blockers and iOS privacy features silently block client-side pixels, resulting in 20% to 40% of real purchases never reaching ad platforms.
PROBLEM 02
Incorrect Attribution
Discrepancies between ad platform dashboards and bank accounts leave media buyers guessing which campaigns are genuinely driving profitable revenue.
PROBLEM 03
Broken GA4 Events
Duplicate purchase tags firing on refresh, missing currency or item parameters, and unmapped measurement IDs lead to inflated, untrustworthy analytics.
PROBLEM 04
Incomplete Audiences
When pixel signals drop off, retargeting pools shrink rapidly and algorithm lookalike optimization loses the high-intent data needed to scale.
PROBLEM 05
Meta CAPI Issues
Low Event Match Quality (EMQ) scores, missing user parameters, and flawed server deduplication cause underreported or double-counted conversions.
PROBLEM 06
Shopify Tracking Gaps
Checkout domain jumps, untracked post-purchase upsells, and third-party app script conflicts break full-funnel customer visibility.

E-commerce / NL
Slageronline.nl: +22% Event Match Quality & 35% Recovered Purchases
Dutch e-commerce butcher was running Meta Ads blind with ~35% of purchases lost to iOS tracking restrictions. Deployed sGTM on Stape.io with a custom subdomain, Meta CAPI deduplication, and full GA4 e-commerce mapping.

DTC / NL
NordSleeps: 400-Day Cookie Persistence & Container Rebuild
Safari ITP capped cookies at 7 days, making returning customer attribution difficult, while 40+ dead tags caused event conflicts. Deployed first-party server cookies via sGTM and rebuilt Shopify e-commerce tracking with zero duplicates.

Packaging Discounter: +60% Conversion Recovery & 100% Reconciliation
GA4 was missing roughly 60% of conversions compared to store orders due to 3 conflicting purchase tags. Identified discrepancies, rebuilt GTM around a single source-of-truth purchase event, and achieved 100% order reconciliation.

FAQ
Common questions
How long does a tracking audit take?
A complete diagnostic tracking audit is typically delivered within 2 to 3 business days from receiving account access. You receive a written report highlighting data leaks, prioritized issues, and an actionable roadmap for remediation.
Can you fix an existing GA4 or GTM setup?
Yes. Most projects involve fixing inherited or messy setups. I remove orphaned tags, eliminate duplicate conversion triggers, correct measurement ID routing, and validate event parameters in GTM Preview and GA4 DebugView.
Do you work with Shopify and other platforms?
Yes. I frequently implement tracking for Shopify, WooCommerce, Magento, custom web apps, SaaS platforms, and lead generation websites across different CMS environments.
Do you support Meta CAPI and Google Ads tracking?
Yes. I set up Meta Conversions API with server deduplication against the browser pixel, as well as Google Ads conversion tracking with Enhanced Conversions to maximize match rates and campaign bidding signals.
What is server-side tracking and do I need it?
Server-side tracking (sGTM via Stape.io or Google Cloud) routes conversion events through your own first-party subdomain instead of relying purely on browser-based scripts. This bypasses ad-blockers, extends Safari ITP cookie lifetime up to 400 days, and recovers 20% to 40% of conversions that browser-only setups miss.
