Smart Shopping Is Deprecated: Migrate to PMax (2026)

If you're still looking for Smart Shopping campaigns, the short answer is: they're gone. Google auto-upgraded all Smart Shopping and Local campaigns to Performance Max (PMax) back in late 2022, and PMax is now the workhorse campaign type for ecommerce on Google. This piece is for anyone with Smart Shopping traces still in their account — or who just inherited a legacy account: what happened, whether to pick PMax or Standard Shopping now, and how to migrate without losing history.

What happened: Smart Shopping's exit

Smart Shopping was PMax's predecessor — also AI-driven, cross-channel automation, but weaker and with less visibility. Around mid-to-late 2022, Google used a "one-click upgrade" tool to auto-migrate existing Smart Shopping campaigns into PMax, and you could no longer create new Smart Shopping after that. So you shouldn't have a genuinely running Smart Shopping campaign today; any leftover naming or historical data is just an old label.

Why did Google do this? Because PMax expanded Smart Shopping's reach (Search + Shopping + Display) to all channels: adding YouTube, Discover, Gmail and Maps. For Google it unified the product line; for advertisers it means you lost some manual control in exchange for broader automated reach. Whether that's good or bad depends on your account maturity — more on that next.

Worth flagging: there's also a separate, easily confused migration in 2026 — the Content API for Shopping is being replaced by the new Merchant API, with several 2026 deadlines (earlier for beta users, later for regular users). This is unrelated to Smart Shopping → PMax; it only affects the technical plumbing of feeding your feed via API. Verify the exact dates in Google's official announcements.

The real decision now: PMax or Standard Shopping

Since Smart Shopping is gone, your actual choice is how to divide labor between PMax and Standard Shopping — those are ecommerce's two Shopping lanes in 2026.

• Choose PMax when you want scale, broad reach, and prospecting. It eats all of Google's inventory and lets AI find volume — fit for many SKUs and cross-channel amplification. For setup and asset groups, see the complete Performance Max guide for ecommerce.
• Choose Standard Shopping when you want query-level control, negative keywords, and margin tiering. It gives you the fine control PMax can't — fit for guarding high-margin hero products.

The sturdier move is usually not either/or but a hybrid: Standard Shopping guards hero products, PMax handles scaled prospecting. For exactly which cannibalizes which and how to split budget, there's a dedicated piece: PMax vs Standard Shopping. If you're still at the "which Shopping lane at all" stage, start with Google Shopping vs Performance Max.

A caveat: PMax's specific mechanics (channel allocation, search-terms visibility, bidding behavior) keep changing, so as of mid-2026, verify your account's current options in Google Ads.

Migrating a legacy account: how not to lose history

If you just inherited an old account with Smart Shopping history, or one that was never standardized, the thing to fear most during migration is wiping out conversion history and learning in one stroke, forcing smart bidding into a cold start. Key principles:

1. Don't delete — run in parallel first

Don't just pause the old campaign, spin up a blank PMax, and launch. The safer move is to run old and new in parallel for a short stretch, confirm the new PMax is actually getting volume and conversions are reporting normally, then gradually shift budget over. A sudden switch costs you data continuity instantly.

2. Conversion tracking must be right first

PMax depends on accurate conversion data even more than Smart Shopping did — its AI learns entirely from the conversions you feed back. Before migrating, confirm conversion tracking, enhanced conversions and Consent Mode v2 are all set correctly, or the new campaign cold-starts on wrong data and drifts further off. How to get this right: Google Ads conversion tracking and GA4 setup.

3. Carry over proven structure, don't rebuild from scratch

The assets already proven to work in the old account — a good product feed, high-converting product groups, custom-label tiers — should carry over into the new structure. Historical data (conversions, clicks, product performance) lives at the Merchant Center and account level; changing campaign type doesn't make it vanish. What truly gets lost is the learning progress inside a single campaign, which is exactly why you transition in parallel and give the new campaign time to relearn.

4. Give the learning period time

A new PMax has a learning period after launch (usually counted in weeks), during which performance swings are normal. Don't make frequent big changes or slash budget in the first few days because the data looks ugly — that resets learning and it never gets off the ground. Give volume, give time, optimize once it stabilizes.

What to do after migrating

Once you've switched to PMax, don't go hands-off:

• Use channel-level reporting to see where money goes — in 2026 PMax can report by channel (Search, YouTube, Discover, etc.).
• Add negative keywords to sculpt traffic — PMax's negative keyword cap rose sharply (from 100 to 10,000); use it to block waste. See Google Ads negative keywords and the search terms report.
• Consider splitting out Standard Shopping to guard hero products — put high-margin bestsellers in Standard Shopping to reclaim query-level control.

Frequently asked questions

I can still see Smart Shopping in my account — did migration fail? Smart Shopping was auto-upgraded to PMax back in late 2022; there shouldn't be a genuinely running Smart Shopping campaign today. What you're seeing is most likely historical data or an old naming label — go by the actual campaign type shown in Google Ads.

Will migrating from Smart Shopping to PMax lose my historical data? History at the account and Merchant Center level (conversions, product performance) doesn't vanish; what resets is the learning progress inside a single new campaign. So transition in parallel, confirm conversion tracking is correct first, and give the new campaign time to relearn.

Is the 2026 Content API / Merchant API migration the same thing? No. That's a technical migration of the API plumbing that feeds your feed, with separate 2026 deadlines, and only affects people using the API. Smart Shopping → PMax was a campaign-type change completed back in 2022.

Can I still use Standard Shopping after migrating? Yes. Standard Shopping still exists and is useful for guarding high-margin hero products and keeping query-level control. The common pattern is a hybrid: PMax for prospecting plus Standard Shopping to guard hero products.

Bottom line

Smart Shopping isn't "about to be deprecated" — it was replaced by PMax back in late 2022. What a legacy account needs today isn't to "migrate Smart Shopping" but to think through the division of labor between PMax and Standard Shopping: PMax for prospecting and amplification, Standard Shopping to guard hero products. When migrating a legacy account, get conversion tracking right first, transition old and new in parallel, carry over proven assets, and give the learning period time — don't wipe history in one cut. PMax's mechanics keep changing, so verify your account's current options in Google Ads before you act.
