Solve Your E-commerce Attribution Nightmare with the Google Cloud & dbt Core Stack
Are your ad platforms all claiming credit for the same sale? Fragmented data from Meta, Google Ads, and your email platform creates a chaotic view of performance. Each system operates in a silo, over-reporting conversions and making it impossible to calculate your true Return on Ad Spend (ROAS). Compounded by data loss from iOS 14+ and browser privacy changes, you're left making critical budget decisions in the dark.
This playbook provides the blueprint to build a single source of truth for your marketing data. We'll show you how to centralize every touchpoint—from ad clicks to Shopify sales and HubSpot CRM activities—into Google BigQuery. Using the power of dbt Core, you'll transform this raw data into a unified, chronological customer journey. Finally, with Looker Studio, you'll build powerful, accurate attribution models and dashboards that reveal exactly which channels are driving real growth, freeing you from the limitations of flawed, client-side tracking pixels.

Integration Logic

Stitch
This integration uses Stitch to connect to Shopify and HubSpot APIs as data sources. Stitch extracts raw data for objects like Orders, Customers, and Products from Shopify, and Contacts, Companies, and Deals from HubSpot. It then loads this data into a designated destination, typically a cloud data warehouse (e.g., Snowflake, BigQuery, Redshift). The data is replicated in its raw, structured format, allowing you to perform complex transformations and analyses using SQL or BI tools, joining data from both systems to gain comprehensive insights.
