If your Pixel or Conversion API isn't set up right, you're leaving money on the table. Bad tracking is silent. Your campaigns look like they're running fine - until you realize your pixel is firing twice, your server events aren't deduplicating, or iOS 14 has quietly wiped out half your attribution.

Are you losing more than 30% of your marketing data to iOS privacy updates and ad-blockers? If your GA4, GTM, Google Ads or Meta Pixel tracking is under-reporting, your ad algorithms are "starving"—and when algorithms don't receive clean signals, your ROAS drops and your cost-per-acquisition (CPA) skyrockets. I am a Stape Certified Server-Side Tracking Specialist and Google Analytics Certified Expert with 5+ years of hands-on experience. I specialise in building "bulletproof" measurement architectures that bypass browser restrictions and restore your data accuracy using Server-Side Tagging (sGTM) and Conversion APIs. 🎯 How I help you scale your ad performance: ✅ Recover Lost Data: I use sGTM to capture missing conversions and improve event match quality for Meta (CAPI), TikTok, and Google Ads—while applying deduplication logic to prevent double‑counting between browser and server events. ✅ Improve Attribution Accuracy: I help businesses send cleaner and more reliable conversion data to Meta, Google Ads, and other platforms so ad algorithms can optimise campaigns more effectively and improve ROAS. ✅ Google Consent Mode v2: I will implement mandatory compliance (Advanced Mode) to recover a significant portion of data through conversion modelling. ✅ First-Party Data Strategy: I will utilise Stape and Google Cloud to set up durable, server-set cookies that track the full customer journey. ✅ Actionable Dashboards: I will transform messy data into high-converting Looker Studio reports that show your true ROI. 🚀 Technical Expertise Across Platforms: Tracking: GTM (Web & Server-Side), Google Ads, GA4 E-commerce, Meta CAPI, TikTok Events API, Pinterest, LinkedIn, & Snapchat APIs. CMS & CRM: WordPress (WooCommerce), Shopify, GoHighLevel (GHL Integration), Magento 2, and Webflow. Hosting: Stape, Google Cloud (GCP), and TAGGRS. Why work with me? ✅Every project ends with a full validation report — screenshots, event confirmation, and documented implementation — so you know exactly what was built and that it works ✅ After-Sales Support: 30 days of complimentary post-service support. ✅ Dedicated Service: Personalised attention as a committed solo freelancer. ✅ Clear Communication: Fluent in English, available for video calls and messages. “I only take on projects I can deliver successfully.” Ready to fix your tracking and scale with confidence?

Broken tracking quietly wastes ad budget every single day. Your Google or Microsoft Ads account sees a click and, if you are lucky, a conversion. The lead worth $8,000, the duplicate event inflating your cost per acquisition, the offline sale that never made it back to the platform: none of it reaches your bidding. So the algorithm scales the wrong signals, and your budget follows. I fix the data first, then I manage the spend. Every decision rests on numbers you can trust. I am Masum Jia (MJ), a Google Ads and conversion attribution specialist with 6 years in paid media and tracking. Top Rated Plus on Upwork with a 100% Job Success Score across 37 contracts. I have built 200+ tracking implementations for ecommerce stores, lead generation businesses, and agencies in 15+ countries, and I manage Google Ads and Microsoft Ads accounts on top of that same tracking foundation. I treat paid ads management and conversion attribution as one system, not two services. Most freelancers do one or the other. An ads manager optimizes campaigns and assumes the data is right. A tracking specialist fixes the data and hands it off. I do both, in order. I call it the Signal-First Method: audit and repair the tracking, prove it is accurate, feed clean conversion and revenue signals back into Google and Microsoft, then optimize the spend against data that reflects real business outcomes. What I bring: ↳ Top Rated Plus and a 100% Job Success Score across 37 contracts in 15+ countries. ↳ 200+ server-side and web tracking builds that survive iOS restrictions, cookie deprecation, and browser-level blocking. ↳ Hands-on Google Ads and Microsoft Ads management, audits, and QA, built on the same tracking foundation most ads managers ignore. ↳ Server-side architecture on Stape io that extends first-party cookie lifespan to 400 days for more complete attribution. One client on a recent project: "Went above and beyond expectations. Mohammad is exceptionally skilled and experienced. I highly recommend him for professional and timely delivery of work." What I work on: ↳ Google Ads management, audit, and QA: Search, Performance Max, Shopping, Display, and Demand Gen ↳ Microsoft / Bing Ads setup, management, and migration from Google Ads ↳ Conversion tracking and attribution across the full customer journey ↳ Server-side tracking via Google Tag Manager and Stape io ↳ Offline conversion tracking and Enhanced Conversions for lead generation and service businesses ↳ GA4 and Google Tag Manager full setup with custom data layer configuration ↳ Meta Pixel and Conversion API, plus TikTok, LinkedIn, Pinterest, Snapchat, X, and Reddit pixels ↳ Consent Mode V2 for GDPR and cookie compliance ↳ Shopify dual-side tracking, browser and server running together ↳ Looker Studio dashboards for clean, client-ready reporting I work best with lead generation, service, and ecommerce businesses spending $2,000 to $50,000 per month who are done optimizing on data they do not trust. If your cost per acquisition looks wrong, your offline sales never reach the platform, or your last ads manager scaled spend on broken conversions, that is the exact problem I solve. How I work: audit, fix, verify, document, optimize. Every setup is tested in GTM preview mode and GA4 DebugView before it goes live. Nothing ships unverified. You get full documentation of what was built and why, and you work directly with me, never a junior contractor. Top Rated Plus is awarded to the top tier of Upwork talent for client satisfaction across large contracts. Clients who are serious about profitable paid media start with clean data and one specialist who owns both sides. That starts here.
