We’re looking for an experienced Google Tag Manager (GTM) and Google Analytics 4 (GA4) specialist to complete the tracking setup for our e-commerce website. The goal is to have a bullet-proof data layer + event tracking system that covers the entire user journey — from first visit to purchase — and provides clear conversion insights and drop-off points. An account with GTM and GA4 access will be provided. Current State: - GTM container is already installed and connected on the live site. - DataLayer is implemented and pushes multiple custom events (e.g. product_click_from_slider, add_to_cart, etc.). - Some variables and triggers exist but are not yet fully connected to GA4. Your Tasks: - Review and optimize the existing GTM setup (tags, triggers, variables). - Complete the GA4 configuration and event mappings. - Set up all relevant e-commerce and engagement events, such as: -- view_item_list -- select_item (product click) -- view_item -- add_to_cart -- remove_from_cart -- begin_checkout -- add_payment_info -- add_shipping_info -- purchase -- Form submissions, outbound clicks, and scroll depth - Implement conversion tracking for checkout and thank-you pages. - Add drop-off and funnel tracking (where users abandon the process). - Configure custom parameters (e.g., product category, slider source, page type). - Enable consent mode v2 and ensure proper behaviour with the site’s cookie banner (EU compliance, the banner exists already). - Verify all events in DebugView and Realtime reports. - Create a brief documentation on how to add new events or modify existing ones. - Connect to Adwords to start running campaigns. Deliverable: - Fully functional GA4 tracking via GTM, aligned with Google’s recommended e-commerce schema. - Verified data flow from GTM → GA4 (all events firing correctly). - List of tracked events and parameters. - Optional: simple dashboard or GA4 Exploration template for conversions and funnels. Requirements: - Proven experience with Google Tag Manager, GA4, and Enhanced E-commerce implementations. - Ability to debug and test DataLayer pushes. - Understanding of consent mode and cookie compliance. - Clear documentation and communication in English or German. Bonus: - Experience with WooCommerce or headless setups (WordPress + Nuxt/Vue frontend). - Familiarity with server-side tagging or GA4 BigQuery exports. Important: This is not just a tag placement job — we need a complete, reliable analytics foundation that can be extended in the future. More events may be added later by the developer as we refine the user journey and marketing attribution.
