Project Details
📘 Project Description : –
The client—an online fashion retailer—was running Google Ads but lacked product-specific retargeting. Generic display ads led to poor CTR and high CPA.
We implemented a complete dynamic remarketing setup via Google Tag Manager, integrated with Google Merchant Center. Product-level data is now dynamically passed via custom dataLayer variables. GTM handles all event tags, while the Google Ads Remarketing Tag and Dynamic Event Snippets track key interactions.
📊 Key Events Tracked for Remarketing ----
| Issue | Description |
|---|---|
| ❌ Generic Retargeting | One-size-fits-all ads led to low engagement and poor CTR |
| ❌ Missing Funnel Events | Incomplete tracking limited segmentation depth |
| ❌ No Dynamic Product Ads | Lack of product-level retargeting hurt ROAS |
| ❌ Privacy Risks | No Consent Mode for GDPR/CCPA compliance |
| ❌ Low Return Visitor Conversion | Weak signals led to inefficient budget allocation |
| Event Name | Tracked | Parameters Captured |
|---|---|---|
view_item | ✅ | product_id, name, category, price |
add_to_cart | ✅ | product_id, quantity, value |
purchase | ✅ | transaction_id, total_revenue, currency |
phone_call | ✅ | call_source, call_duration, user_location |
After giving a preview from the GTM Browser Server-side, we see that all tags have fired successfully.
