At Google Marketing Live in May 2026, Google announced AI Max for Shopping -- a new campaign format designed to replace Performance Max as the primary AI-driven campaign type for e-commerce advertisers. The transition is underway, and e-commerce sites that understand what changes early will be better positioned during the migration window.
This guide covers what AI Max for Shopping is, how it differs from Performance Max, what the migration process looks like, and the practical steps online retailers should take now.
What Is AI Max for Shopping?
AI Max for Shopping is Google's next-generation campaign type for product advertising. It replaces Performance Max's all-in-one approach with a shopping-specific AI system that controls targeting, creative, bidding, and placement across Google's shopping surfaces.
The core differences from Performance Max:
Shopping-first inventory prioritization. Performance Max distributed budget across all Google inventory including Search, Display, YouTube, Gmail, and Maps. AI Max for Shopping concentrates inventory on shopping surfaces: Google Shopping tab, product listings in Search, and buy-intent YouTube placements. Non-shopping inventory receives less budget by default.
Feed-native AI creative. Performance Max could generate ad creative from uploaded assets using AI. AI Max for Shopping generates creative natively from your product feed -- titles, descriptions, and image enhancements are derived directly from product data rather than from separately uploaded asset groups.
Enhanced product-level signals. AI Max for Shopping uses deeper product-level performance signals including review data, return rate signals, and product page quality indicators that Performance Max did not access directly.
Simplified campaign structure. Performance Max required asset groups with multiple creative types. AI Max for Shopping reduces creative setup requirements by relying more heavily on feed data.
What Stays the Same
Several elements carry forward from Performance Max:
- Smart Bidding remains the underlying bidding mechanism. Target ROAS and Maximize Conversion Value strategies work the same way.
- Google Merchant Center feed remains the foundation. Product data quality, titles, descriptions, and images still directly determine performance.
- Audience signals remain supported. Customer match lists and similar audience signals can be provided as inputs.
- Conversion tracking setup does not change.
Who Is Affected
AI Max for Shopping primarily affects:
Standard e-commerce retailers running Performance Max campaigns with shopping inventory as the primary intent. These accounts will see the most significant change in campaign structure.
Retailers using Performance Max for non-shopping objectives (brand awareness on Display and YouTube, local inventory) may find AI Max for Shopping less suitable for those objectives and should plan to maintain separate campaign types for non-shopping goals.
Accounts with heavy reliance on Performance Max asset groups will need to reassess creative strategy as AI Max for Shopping reduces the role of manually uploaded creative assets.
What the Migration Process Looks Like
Google is rolling out AI Max for Shopping as an upgrade path from Performance Max. The migration is not automatic for all accounts simultaneously -- it is being introduced in stages.
For accounts where AI Max for Shopping becomes available:
- Google Ads interface will show an upgrade prompt in Performance Max campaigns with significant shopping inventory
- Accepting the upgrade converts the campaign to AI Max for Shopping format
- Historical bidding signals and conversion data transfer to the new campaign
- Asset groups in the original Performance Max campaign are archived but accessible for reference
Maintaining both formats simultaneously during a transition period is possible by creating a new AI Max for Shopping campaign alongside the existing Performance Max campaign, running them in parallel, and phasing out Performance Max as the new campaign demonstrates stable performance.
Practical Steps for E-Commerce Sites
Audit your Merchant Center feed before migrating. AI Max for Shopping relies more heavily on feed data for creative generation. Ensure product titles include primary keywords, descriptions are complete, images meet Google's quality requirements, and all required attributes are present. Feed quality has always mattered for shopping campaigns -- it matters more for AI Max for Shopping.
Review your ROAS targets. AI Max for Shopping's initial learning period may show temporary performance fluctuation similar to launching a new Performance Max campaign. Set ROAS targets based on historical averages rather than peak performance to give the system room to learn without triggering budget pauses.
Plan for the inventory shift. If your current Performance Max campaigns allocate significant budget to Display or YouTube inventory for brand awareness, understand that AI Max for Shopping will redirect that budget toward shopping surfaces. If brand awareness is a goal, maintain separate Display or Video campaigns.
Check Google Analytics 4 integration. Conversion data imported from GA4 should be reviewed for accuracy before migration, as AI Max for Shopping uses conversion signals more intensively than Performance Max.
Document current Performance Max performance. Export campaign reports, asset group performance data, and product-level data before migrating. This baseline helps evaluate AI Max for Shopping performance after the transition.
SEO Connection: Shopping Campaign Data in Google Search Console
The July 2026 GSC update added performance data for various Google platforms. Shopping results in Google Search are distinct from standard organic results and appear in their own data segment in Search Console. For e-commerce sites using AI Max for Shopping, understanding how shopping traffic shows in GSC gives a more complete picture of search presence.

Frequently Asked Questions
When will Google force all Performance Max accounts to migrate to AI Max for Shopping?
Google has not announced a mandatory migration date. The rollout is being presented as an upgrade path rather than a forced migration. However, AI Max for Shopping is clearly the direction of future development, and Google is likely to phase out Performance Max for shopping-intent accounts over time.
Will AI Max for Shopping work with Google Shopping free listings?
AI Max for Shopping operates on paid inventory. Free Shopping listings through Google Merchant Center operate independently and are not part of AI Max for Shopping campaign structure.
Do I need to recreate my conversion actions when migrating?
No. Existing conversion actions and tracking set up for Performance Max transfer to AI Max for Shopping. No new conversion tracking setup is required.
Can I run AI Max for Shopping and Performance Max simultaneously?
Yes, during a transition period. Running both allows comparison of performance before fully committing to AI Max for Shopping. Budget allocation between the two campaigns requires monitoring to avoid internal competition for the same product inventory.
Will AI Max for Shopping campaigns show in Google Search Console?
Paid shopping results appear in the Google Ads interface, not in Search Console. Search Console shows organic search performance including organic Shopping tab appearances. Paid AI Max for Shopping traffic will appear in GA4 as paid search traffic.
