Google Ads Audience Targeting for eCommerce: The 2026 Complete Guide
In 2026, audience signals are as important as keywords for many campaigns: Smart Bidding and AI Max handle bids and query expansion; your lists and segments steer learning.
Core audience types
- Remarketing lists — Segment visitors, product viewers, cart abandoners, purchasers (exclude buyers from wasteful prospecting where appropriate).
- Customer Match — Email lists for buyers, subscribers, win-back; pair with value-based bidding when possible.
- In-market — Add in Observation first to collect ROAS/CVR by segment.
- Custom segments — Built from purchase-intent searches around your categories.
Observation vs targeting
Default to Observation so you do not choke reach while learning. Apply bid adjustments or targeting only when data supports it.
