Anyone running Google Ads for an e-commerce business will already be familiar with Shopping ads. These product-based ads appear in Google search results and showcase key information, including product images, pricing, brand details, and reviews.
In Google Ads, Shopping activity is typically managed through either:
- Standard Shopping campaigns, or
- Performance Max (PMax) campaigns.
One of the most common questions ecommerce advertisers face is:
Should you run Standard Shopping campaigns or PMax campaigns?
The answer depends on your business goals, account structure, product catalogue, available creative assets, and the level of control you want over campaign performance.
In this article, we’ll look at the key differences between Standard Shopping and PMax campaigns, along with the advantages and limitations of each approach.
What Are Standard Shopping Campaigns?
Standard Shopping campaigns have been part of Google Ads for many years and continue to play an important role in e-commerce PPC strategies.
These campaigns allow advertisers to:
- Select specific products or product groups from a feed
- Set campaign priorities and budgets
- Choose manual or automated bidding strategies
- Target specific locations and audiences
- Maintain tighter control over campaign structure
Unlike PMax campaigns, Standard Shopping campaigns focus exclusively on Shopping placements within Google’s Shopping network.
Although Google has invested heavily in automation over recent years, Standard Shopping campaigns still offer advantages that many e-commerce businesses value.
Key Advantages of Standard Shopping Campaigns
Greater Control Over Bidding
One of the biggest differences between Standard Shopping and PMax is the ability to use manual bidding strategies.
While automated bidding has become increasingly effective, manual bidding can still be useful in certain situations – particularly for short-term promotions, seasonal sales, or stock-clearance activity.
For example, if an e-commerce business wants to increase visibility aggressively for a limited-time offer, manual CPC bidding can sometimes react faster than automated strategies.
Automated bidding strategies such as:
- Maximise Conversion Value
- Target ROAS (Return on Ad Spend)
typically require a learning period after launch or major campaign changes. During this period, performance can fluctuate while Google’s algorithm gathers data and adjusts bidding behaviour.
For shorter promotional periods, some advertisers prefer the immediate control offered by manual bidding.
More Control Over Placements
Another major advantage of Standard Shopping campaigns is placement control.
Standard Shopping campaigns serve ads within the Shopping network only. This makes it easier to maintain visibility, specifically within high-intent product searches.
PMax campaigns work differently. They distribute the budget across multiple Google properties, including:
- Search
- Shopping
- Display
- YouTube
- Discover
- Gmail
While this broader reach can improve scale, it also reduces control over where ads appear.
For businesses that want tighter placement control and a more focused Shopping strategy, Standard Shopping campaigns can still be a strong option.
What Are PMax Campaigns?
Performance Max campaigns are Google’s fully automated, multi-network campaign type.
Unlike Standard Shopping campaigns, PMax uses:
- Shopping feeds
- Headlines
- Descriptions
- Images
- Videos
- Audience signals
to serve ads across Google’s entire advertising ecosystem.
Google’s algorithm automatically decides:
- where ads appear,
- which audiences to target,
- and how the budget should be allocated across networks.
It is also worth noting that product feeds are optional within PMax campaigns. This highlights that PMax is not simply a Shopping campaign replacement – it is a broader automation-based campaign type designed to maximise conversions across all Google inventory.
Feed-Only PMax Campaigns
Some advertisers choose to run PMax campaigns in a “feed-only” configuration.
This setup removes most creative assets and relies primarily on the product feed itself. The aim is usually to:
- reduce Display and YouTube exposure,
- keep activity closer to traditional Shopping behaviour,
- and maintain cleaner ecommerce-focused traffic.
However, Google does not make feed-only PMax setups particularly straightforward.
Typically, advertisers must:
- Create a standard PMax campaign with full assets
- Publish the campaign
- Open the campaign within Google Ads Editor
- Create a new asset group containing only the product feed
- Remove or pause the original full-asset group
Although this process is relatively simple once familiar with it, it does add additional setup complexity.
It is also important to understand that even feed-only PMax campaigns can still occasionally serve ads outside the Shopping network.
Advantages of PMax Campaigns
Cross-Network Learning
One of the main advantages of PMax campaigns is Google’s ability to use data and learnings across multiple networks simultaneously.
For example, if a conversion occurs through a YouTube or Search placement, Google can apply those audience insights when bidding on Shopping inventory as well.
This cross-channel learning can help improve:
- audience targeting,
- conversion efficiency,
- and overall campaign scale.
For e-commerce businesses with strong conversion data and sufficient budget, this can produce excellent results.
Better Use of Automation
Google continues to invest heavily in PMax development and automation capabilities.
Recent improvements include:
- dynamic landing page expansion,
- automatically generated ad assets,
- and improved bidding intelligence.
As Google continues prioritising automation, PMax campaigns are likely to receive more ongoing feature development than Standard Shopping campaigns.
For businesses with:
- strong conversion tracking,
- high-quality creative assets,
- and healthy conversion volume,
PMax can often outperform more manual campaign structures.
When Standard Shopping May Be the Better Option
Standard Shopping campaigns may still be the better choice when:
- tighter placement control is required,
- manual bidding flexibility is important,
- promotional activity changes frequently,
- creative assets are limited,
- or businesses want greater transparency over campaign behaviour.
They can also work well for advertisers who prefer more granular segmentation and control across product categories.
When PMax May Be the Better Option
PMax campaigns are often better suited to businesses that:
- want to scale activity across multiple Google channels,
- have strong historical conversion data,
- can provide high-quality creative assets,
- and are comfortable with a more automated campaign structure.
They are particularly effective for e-commerce brands looking to combine Shopping, Search, Display, and YouTube activity within a single campaign framework.
Should You Run Both?
In many e-commerce accounts, the best solution is not necessarily choosing one campaign type over the other.
Some advertisers achieve strong results by running:
- Standard Shopping campaigns for selected products or promotional activity,
- while using PMax campaigns for broader scaling and automation.
The right structure depends entirely on:
- business objectives,
- profitability targets,
- catalogue size,
- campaign budgets,
- and overall PPC strategy.
Testing both approaches and reviewing performance data over time is often the best way to identify the most effective setup.
Final Thoughts
Both Standard Shopping and PMax campaigns have a place within modern e-commerce PPC strategies.
Standard Shopping campaigns still offer valuable control and flexibility, particularly for advertisers who want tighter oversight of placements and bidding behaviour.
PMax campaigns, on the other hand, provide broader reach, stronger automation capabilities, and cross-network learning that can help scale performance efficiently when supported by good-quality data and creative assets.
Choosing the right approach depends on your business goals, account structure, and the level of automation that makes sense for your e-commerce strategy.
If you’re unsure whether your current Google Ads setup is structured effectively, a professional PPC audit can often identify opportunities to improve performance, efficiency, and return on ad spend.
