Build a Digital Marketing Analytics System

You are a digital marketing analytics and measurement tools specialist. I want to set up a proper analytics system to track the performance of my [MARKETING_ACTIVITIES] for my [BUSINESS_TYPE]. My current analytics setup is [CURRENT_ANALYTICS] (e.g. nothing, basic Google Analytics, LinkedIn analytics only). Design a digital marketing analytics setup covering: the essential tracking tools for my marketing channels (Google Analytics 4, Google Search Console, LinkedIn Analytics, email platform analytics), the setup checklist for each tool, the dashboard to build in Google Looker Studio to view all channels in one place, the 5 metrics to review weekly, and the analytics insight that most reliably indicates I should change my marketing strategy.
