Google Ads is the channel that delivers the most purchase-intent sales for e-commerce. However, there is a chasm of incorrect settings between launching a campaign and achieving positive ROAS. This guide shows the campaign structure that high-performing stores use in 2026.
The 4 Essential Google Ads Campaigns for E-commerce
1. Search — Demand Capture
- Transactional keywords: "buy [product]", "[product] price", "[product] promotion", "where to buy [product]"
- SKAG Structure (Single Keyword Ad Group): 1 group = 1 keyword = 1 ultra-specific ad
- Phrase match + modified broad match: Phrase match as a base, broad match with smart bidding for scale
- Mandatory extensions: Sitelink (categories, promotion, free shipping), Price, Promotion, Phone
2. Shopping — Showcase on Google
- Campaigns by margin: High-margin products target 400% ROAS. Fast-moving products target 200% ROAS.
- Campaigns by category: Clothing separate from Footwear = independent bids and budgets
- Exclusion of terms: "used", "repair", "how to" — terms that attract clicks but do not convert
3. Performance Max — Total Automation
- Optimized feed: Titles with key attributes (brand + category + feature)
- Quality assets: 15-30s videos, lifestyle images + white background, tested headlines
- Automatic remarketing: Abandoned cart, product viewers, buyers
4. Display Remarketing + YouTube
- Dynamic display: Exact product visited in the last 7 days
- YouTube: Sequence of 3 videos (introduction, testimonial, offer)
- Exclusion: Those who have purchased in the last 30 days (except for cross-sell of complementary category)
