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.

🚦 Challenges Identified :

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

📊 Key Events Tracked for Remarketing :

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.
