Conversion tracking is the setup that records when a visitor completes a valuable action, like a purchase or lead form, and reports it to analytics and ad platforms. When it breaks, budgets go to the wrong places without any visible error. The three posts here cover quiet failures such as duplicate counts and empty user data, moving custom conversions to GA4 key events, and rebuilding measurement during a migration to Shopify.
Broken tracking is the most expensive problem in ecommerce advertising because it never announces itself. No error appears, conversions keep counting, and the spend keeps flowing while performance quietly erodes. This walks through the silent tracking failures that drain ad budgets and the diagnostic habits that catch them before they cost a quarter.
Migrating to Shopify is rarely a clean technical operation. It is a redistribution of risk across systems that previously worked together by accident. This checklist walks through the decisions that compound, from URL strategy and tracking foundations to attribution, email migration, and the post-launch audit that most teams declare too early.
Transitioning from traditional conversion tracking to the new Google Analytics 4 Key Events framework requires precision. This article explores the technical migration process, BigQuery schema implications, and strategic alignment for global industries.
