Google Smart Shopping vs Performance Max: What Changed and What Still Works

TL;DR: You can no longer create Google Smart Shopping campaigns. Google automatically upgraded existing Smart Shopping campaigns to Performance Max in 2022. Performance Max offers wider inventory and more reporting and controls, but it remains an automated campaign type — not a one-for-one replacement for every Standard Shopping use case.

If you are searching for a Smart Shopping setup guide, the old steps are no longer actionable. Below, we'll explain how Smart Shopping worked, what changed with Performance Max, and which Shopping principles are still relevant.

Important: More reporting doesn't mean every placement, audience, or bid can be controlled manually. Performance Max still optimizes delivery automatically.

Google launched Smart Shopping in 2018 as an automated campaign type for retailers. It combined product data from Google Merchant Center with Google's machine learning to place Shopping ads and reach potential customers across Google properties. Retailers chose a budget and conversion goals; Google handled much of the bidding and ad delivery.

Its selling point was simplicity. The trade-off was limited insight into the searches, channels, and audiences responsible for results. Google retired the format in 2022 by migrating campaigns to Performance Max.

Smart Shopping drew product titles, images, prices, and availability from the Merchant Center feed. It used conversion tracking and automated bidding to find opportunities likely to generate conversion value, often against a target return on ad spend (ROAS).

Advertisers could set a daily budget, optionally a target ROAS, and provide creative assets. Unlike more controllable campaign types, they couldn't directly adjust many aspects of targeting or see much of the underlying query and channel detail.

Common limitations included limited ability to manage search terms, negative keywords, campaign priority, network mix, and granular bid adjustments.

In PMax: Advertisers now have search term reports, negative keyword controls, channel performance reports, asset metrics, and additional exclusions. However, PMax still distributes delivery and bidding using automation.

Smart Bidding is Google's automated, auction-time bidding technology. It uses conversion tracking, conversion values, and contextual signals such as device and location to set bids for each auction. Advertisers choose the bidding goal and, where appropriate, a target; they do not manually set each auction bid.

Smart Bidding can be used with different Google Ads campaign types. Before evaluating a strategy, make sure conversion tracking reflects the business outcome you actually want. Google's guidance on conversion volume is primarily about making performance evaluation more reliable, not a universal requirement before automated bidding can begin.

Limited Visibility

Smart Shopping reporting combined results across much of its inventory, making it difficult to understand which queries and channels were driving outcomes.

In PMax: Search terms reporting, channel performance reporting, and asset-level performance metrics offer more transparency. These reports are still not the same as full manual control over where budget is spent.

Limited Control

Smart Shopping offered little room to shape targeting and delivery beyond budgets, goals, and feed quality.

In PMax: Advertisers can use brand exclusions, age and gender exclusions, search themes, and certain device targeting controls. Audience signals are guidance for Google's automation — not rigid targeting rules.

No Ordinary Negative Keyword Controls

Smart Shopping lacked routine campaign-level negative keyword management. This made it harder to proactively exclude irrelevant searches.

In PMax: Account-level and campaign-level negative keywords and negative keyword lists are available.

For practical ways to exclude irrelevant searches, see our Universal Negative Keyword Lists guide.

Standard Shopping campaigns are still available. They use Merchant Center product data to display product-led Shopping ads, while offering a different balance of bidding options, reporting, and campaign structure from Performance Max.

How Standard Shopping Differed From Smart Shopping

Control. Standard Shopping gives advertisers more direct control over product groups and campaign structure. It does not mean complete control over every audience or placement.

Setup. Smart Shopping prioritized automated setup. Standard Shopping typically involves more hands-on choices and ongoing management.

Maintenance. Standard Shopping often requires more active optimization. Neither Standard Shopping nor PMax is truly “set and forget.”

Conversion data. Both formats benefit from accurate conversion tracking. New campaigns can start without a large history of conversions, but limited data can make optimization and evaluation harder.

Location targeting. Standard Shopping supports geographic targeting; current Performance Max also provides location targeting options. The meaningful difference is not simply “country only” versus “local.”

Give Automated Bidding Time to Learn

Major changes to bids, goals, budgets, or assets can affect campaign delivery while the system adapts. Avoid judging results immediately after a change. Look at the conversion cycle and attribution lag when comparing performance periods.

Choose Bidding Targets Based on Business Economics

You don't have to set a target ROAS on day one. Use your margins, conversion values, and campaign history to choose realistic targets. There is no universal rule that an expected 470% ROAS should always be translated into a 450–460% target. A more restrictive target can limit reach, while a looser one may increase volume at a lower return.

Use Better Creative Assets Alongside Your Product Feed

Keep accurate, high-quality product feed images for Shopping inventory. For PMax placements beyond Shopping, also prepare lifestyle imagery, video, headlines, and descriptions suited to different formats. Don't discard useful existing product photography solely because it appeared in Standard Shopping.

Optimize Your Feed and Budget

Check product titles, categories, pricing, availability, and Merchant Center diagnostics. Set a budget you can sustain, and avoid repeated large changes before performance can be evaluated. When testing PMax, consider how other Shopping or Search campaigns could overlap with it.

Evaluate Results by Business Outcomes

Look at conversion value, revenue quality, ROAS, costs, and overall campaign performance rather than relying on impressions alone. Allow enough time for the learning period and delayed conversions; review channel and search-term reports to identify relevant opportunities for improvement.

Smart Shopping is history, but its core lesson remains: product data and conversion signals matter. Performance Max expanded reach and introduced reporting and controls that Smart Shopping lacked, while leaving many decisions in Google's automated system. For advertisers who want a different balance of transparency and control, Standard Shopping remains relevant too.
