GTM / sGTM Expert

We have a Shopify ecommerce store with existing tracking, but we believe some of it may be broken or double-counting. We have now created a Stape sGTM container and want to move toward a clean, scalable setup. We track ecommerce purchases, but we also have other important customer events, including: - Calendly / showroom bookings - Shopify contact form leads - Phone clicks / phone calls - Add to cart - Begin checkout - Purchases - Low-value sample product orders We also sell some low-value sample products, around £3, and these should not become the main optimization signal in Google Ads. The main Google Ads optimization should be based on real purchases / valuable orders, not cheap sample-only orders. Main goal We need someone to review and build the correct tracking and conversion structure, including: Goal / conversion hierarchy We want the setup to be structured correctly, for example: 1. Primary conversion: main ecommerce purchase  This should be the conversion Google Ads optimizes for. 2. Secondary conversions: qualified lead events  Examples: Calendly showroom booking, contact form lead, qualified phone call. 3. Observation / supporting events: add to cart, begin checkout, phone click, calendar click, etc. 4. Sample orders: low-value sample purchases around £3 should be handled carefully. We need advice and implementation on whether to exclude sample-only orders from the main purchase conversion, send them as a separate secondary conversion, or keep them in revenue reporting but prevent them from dominating optimization.
