# Acme Store: tracking stack (fictional example of martech-context/stack.md)

This is the file the worked example reads. It shows the fields the GA4 audit needs; a real one holds no secrets, tokens or personal data.

## Sites and hostnames

- www.example.com: marketing pages, catalogue and blog.
- shop.example.net: cart and checkout, a second registrable domain on the same measurement ID.
- PayPal is offered at checkout; buyers return to shop.example.net/order-confirmation.
- staging.example.com: staging. It should never send to the production property.

## Google Analytics 4

- Property: "Acme Store - GA4", properties/123456789, standard, time zone America/New_York, currency USD.
- Web stream "Acme web": stream 1234567890, G-XXXXXXXXXX, loaded through the GTM container on both hosts.
- No other streams are expected. (The audit found a second one, "Acme web (2023 rebuild)", G-XXXXXXXX.)
- Owner: web analytics lead. Editor access: web analytics lead and one deputy.
- Measurement Protocol: data engineering sends refunds from the order system (one API secret, held by data engineering).

## Google Ads

- Active: 123-456-7890, imports the GA4 purchase and generate_lead key events and uses GA4 audiences.
- Retired: 000-000-0000, the previous agency account, retired 2024-01-31.
- Third-party accounts: none.

## BigQuery

- Project acme-analytics (project number 123456789012), dataset analytics_123456789, location US, daily export.
- The warehouse reports revenue and conversions from the export.

## Consent

- CMP on both hosts; advanced consent mode for Google tags (decisions.md, 2024-02-12).
- Consent required in the EEA, the UK and Switzerland.

## Offices and testers

- Head office traffic is marked internal by IP; agency and call centre staff test from their own networks.
- QA uses staging.example.com and GTM Preview.

## Tracking plan pointers

- Key events: purchase (once per event, value required), generate_lead (sent by GTM after the server accepts the contact form, value 50 USD), sign_up.
- Events GTM sends: purchase, generate_lead, sign_up, view_item, add_to_cart, begin_checkout.
- Decisions this property feeds: Google Ads bidding, the weekly revenue report, the warehouse revenue model.
- History needed in explorations: 14 months. Sales cycle: 45 days.
