Your ad spend is only as good as your tracking data. If your GA4 purchase numbers don't match your store — Shopify, WooCommerce, WordPress, Webflow, Kajabi, Magento, BigCommerce, Squarespace, Wix, or custom-built sites — your Google Ads conversions look inflated, or your Meta CAPI isn't deduplicating — you're optimizing blind. Every day that goes on, your campaigns learn from bad data. I fix that. I'm Arif — a conversion tracking specialist trusted by ecommerce brands, SaaS businesses, and paid ads teams across the US, UK, and Australia. On Upwork alone: 297 completed projects, $100K+ earned, 1,500+ tracked hours, Top Rated. I don't just install pixels. I build end-to-end tracking systems that send the right event, the right value, the right user signals, and the right attribution data to every platform — accurately, every time. What my clients typically come to me with: → GA4 isn't recording purchases or lead events correctly → Google Ads conversions are missing, doubled, or attributed to the wrong campaign → Meta Pixel is firing duplicate events and CAPI isn't deduplicating → Shopify, GA4, and ad platform revenue figures all show different numbers → Server-Side GTM is live but data is still dirty or incomplete → Forms submit but no lead event fires — or fires on every page load → Consent Mode V2 is configured wrong and modelled conversions are off → TikTok Events API or LinkedIn CAPI events aren't matching If any of those sound familiar, keep reading. What I deliver: GA4 & Google Tag Manager Full GA4 setup or audit, ecommerce tracking (purchase, add to cart, checkout), lead and form tracking, custom dataLayer implementation, cross-domain tracking, and DebugView verification. Google Ads Conversion tracking setup and audit, Enhanced Conversions with hashed customer data, offline conversion imports, and dynamic remarketing. Meta Pixel audit and rebuild, Conversion API (CAPI) setup, browser-server event deduplication, Event ID implementation, and Advanced Matching. Server-Side GTM Full sGTM setup, GA4 server-side tagging, Meta and TikTok server-side events, first-party data enrichment, and improved match quality scores. Other PlatformsTikTok Events API, LinkedIn CAPI, Pinterest, Snapchat, Microsoft Ads, and Consent Mode V2 with cookie consent integration. Reporting Looker Studio dashboards that give your team a single source of truth across channels. Platforms I work on: Shopify · WooCommerce · WordPress · Webflow · Kajabi · Magento · BigCommerce · Squarespace · Wix · custom-built sites and more How I work: Audit — I map your full tracking setup and document every gap, mismatch, duplicate, or misconfiguration. Plan — I write a clear implementation spec based on your funnel, platforms, and ad goals — no guesswork. Implement — I build the fix using GA4, GTM, sGTM, dataLayer, CAPI, and API integrations. Verify — I test everything with GTM Preview, GA4 DebugView, Meta Events Manager, Tag Assistant, and platform-specific testing tools before handover. You receive a written summary of what was fixed, what's firing, and how the tracking works — so you or your team can maintain it. Why clients come back: I don't disappear after delivery. Tracking breaks when sites update, consent laws change, or platforms push new requirements. I build setups that are stable, documented, and designed to be maintained — and I'm here when you need changes. Ready to stop making decisions on bad data? Send me a message describing your tracking issue — or invite me to your job. I'll tell you within 24 hours exactly what's broken and what it would take to fix it.
