✅ What Are Smart Shopping Campaigns?
🔹 Overview
Smart Shopping campaigns were designed to automate:
- Bidding
- Targeting
- Ad placement
- Remarketing
They combine Standard Shopping Ads with Display remarketing, and require minimal inputs from the advertiser.
🔹 Key Features

|---|---|
| Networks | Google Search, Display, YouTube, Gmail |
| Automation | Bidding, targeting, creative |
| Required Setup | Product feed + budget + optional ROAS target |
| Asset Control | Limited (ad creatives are auto-generated) |
🔹 Use Cases
- Ideal for retailers with consistent product inventory
- Good for advertisers who want ease over control
- Compatible with Target ROAS bidding
✅ What Is Performance Max (PMax)?
🔹 Overview
Performance Max is the newer, more advanced campaign type that supersedes Smart Shopping. It runs across all of Google’s inventory, including:
- Search
