Build a Zero-Cost Attribution Engine: The Open-Source Powerhouse
Are your ad platforms all claiming credit for the same sale? With each channel like Meta, Google, and TikTok reporting in its own silo, your total reported conversions often exceed actual sales. This makes calculating true ROAS impossible. Compounded by data loss from iOS 14 updates, you're left guessing where to allocate your budget for the best results.
The Open-Source Powerhouse playbook shows you how to reclaim control of your data by building your own analytics stack with free, powerful tools. We guide you through using Airbyte to pull all your marketing and sales data from fragmented sources into a central PostgreSQL database. From there, you'll use dbt to transform the raw data into a single source of truth, allowing you to build accurate, custom attribution models. This solution trades software fees for engineering effort, giving technically-savvy teams on a budget ultimate flexibility and ownership.
Expected Outcomes
- A unified view of the complete customer journey, from first touch to final conversion.
- Accurate, cross-channel Return on Ad Spend (ROAS) calculations you can trust.
- Full ownership and control over your marketing data and analytics stack, free from vendor lock-in.
- Mitigation of data loss from privacy changes like iOS 14 by relying on server-side data.
- Elimination of expensive software licensing fees for data integration and warehousing.

Airbyte
This integration uses Airbyte to create a one-way data pipeline from WooCommerce to Mailchimp. Airbyte's WooCommerce source connector extracts customer, order, and product data from your e-commerce store. This data is then loaded by Airbyte's Mailchimp destination connector into a specified Mailchimp audience. The process automatically creates new subscribers or updates existing ones with the latest information from WooCommerce, such as contact details and purchase history, which can be mapped to Mailchimp's merge fields or tags for segmentation.
