Performance Max vs Standard Shopping: which should an Australian store run?

Every Australian store running Google Ads eventually reaches the same fork. Google's own recommendations push you towards Performance Max, the automated campaign type that serves ads across Search, Shopping, YouTube, Display, Discover, Gmail and Maps from a single budget. Meanwhile, plenty of experienced advertisers still run Standard Shopping, the older product-ad format that gives you far more say over where the money goes. Both can work, and both can quietly waste budget. The useful question is not which is better in general, but which suits your store's stage, data and margins right now.

What is the difference between Performance Max and Standard Shopping?

Both campaign types draw on your Google Merchant Centre product feed to show product ads. The real difference is how much of the decision-making you hand to Google.

Standard Shopping shows product ads in the Shopping placements on Google Search and on the Shopping tab. You decide how products are grouped, set bids or a bid strategy for those groups, see the exact search terms that triggered your ads, and add negative keywords to block irrelevant ones. It is a narrow, transparent tool.

Performance Max takes your feed plus any creative assets you supply and lets Google decide which channel, placement, audience and format to use for each impression, optimising towards your conversion goal. Google has added more reporting and controls over time, including a search terms report, channel performance reporting, negative keywords and brand exclusions. Even so, you steer Performance Max rather than drive it.

	Standard Shopping	Performance Max
Where ads appear	Shopping placements on Google Search and the Shopping tab	Search, Shopping, YouTube, Display, Discover, Gmail and Maps
Bidding	Manual CPC or automated strategies, set by you per campaign or product group	Automated bidding towards conversions or conversion value
Search term visibility	Full search terms report	Search terms report, with less granular control
Negative keywords	Campaign and ad group level	Campaign and account level, plus brand exclusions
Creative needed	Product feed only	Feed plus text, image and ideally video assets
Data it needs	Copes with low volume, especially on manual bids	Performs best with a steady flow of accurate conversions
Main risk	Missing reach and leaving scale on the table	Spend drifting to low-intent placements or brand searches you would have won anyway

When does Standard Shopping make more sense?

Standard Shopping earns its place when control and clarity matter more than reach. That tends to describe stores with:

• Small budgets. On a modest daily spend, you cannot afford for a share of it to drift into display or video placements that rarely convert in your category. Standard Shopping keeps every dollar on product searches with clear buying intent.
• Low conversion volume. Automated bidding learns from conversions. A store taking a handful of online orders a week gives Performance Max very little to learn from. Standard Shopping on manual or simple bidding does not depend on that learning in the same way.
• Uneven margins across the catalogue. If some products carry healthy margins and others barely break even, you want to bid on them differently. Standard Shopping lets you split product groups by margin band and bid accordingly.
• A need to diagnose. Standard Shopping's clean search-term data shows exactly what people searched before they clicked, which feeds your product titles, SEO and negative keyword list.

The trade-off is reach. Standard Shopping only shows ads to people already searching for products, so it rarely creates new demand. For many smaller stores, that is fine for a long time.

When does Performance Max make more sense?

Performance Max earns its place when you have the data and creative to feed it, and when you have reached the ceiling of what pure search intent can deliver. It tends to suit stores that:

• have reliable conversion tracking that passes accurate order values, so the algorithm optimises towards real revenue rather than noise;
• generate a steady flow of conversions, often a few dozen or more a month within the campaign, so bidding has enough signal to settle;
• have creative assets beyond the feed, including lifestyle imagery and simple video, so non-Shopping placements are not filled with weak auto-generated assets;
• want to reach new customers beyond people already searching, which matters in discovery-led categories such as homewares or gifts.

When those conditions hold, Performance Max can uncover demand a manual structure would miss. When they do not, it mostly finds ways to spend the budget.

Can you run Performance Max and Standard Shopping at the same time?

Yes, and many well-run accounts do. The catch is overlap. If the same products sit in both a Performance Max and a Standard Shopping campaign, the two compete in the same auctions. Google has moved to choosing between them on Ad Rank rather than automatically favouring Performance Max, but overlap still muddies reporting: you cannot cleanly say which campaign deserves the credit.

The cleaner approach is to split the catalogue rather than double up on it. Common structures include:

• By margin: high-margin products in Performance Max with a value-based target, and thin-margin products in Standard Shopping with tight bids.
• By track record: best sellers with plenty of conversion history in Performance Max, and new or low-data products in Standard Shopping until they prove themselves.
• By role: Standard Shopping for core, high-intent product searches, and Performance Max scoped to a defined product set for prospecting and reach.

Use custom labels in your Merchant Centre feed to tag products by margin band or role, then include or exclude them by listing group. That keeps each product in exactly one campaign.

How do you stop Performance Max spending on your own brand searches?

One of the most common ways Performance Max flatters itself is by capturing searches for your own store name. Those people were likely to find you anyway, so credit for those sales says little about the campaign's real contribution. Left unchecked, a meaningful share of reported revenue can be branded demand you already owned.

The fixes are now built in. Apply brand exclusions so the campaign does not chase your brand terms, review the search terms report regularly, and add negative keywords for clearly irrelevant queries. If you want brand coverage, run a separate, low-cost brand Search campaign where you can see and control it. This sits within the wider discipline covered in our guide to reducing Google Ads wasted spend.

How should you test Performance Max against Standard Shopping?

Switching everything over on a hunch and judging it after a week is how most stores reach the wrong conclusion. A fairer test looks like this:

1. Pick a product set, not the whole store. Choose a group with enough sales history to produce meaningful results.
2. Keep the comparison clean. Exclude the test products from the other campaign so the two are not bidding against each other.
3. Allow for learning. Automated bidding typically needs a couple of weeks to settle. Judge over four to six weeks rather than four to six days, and avoid changing budgets or targets mid-test.
4. Measure what you keep, not what Google reports. Compare contribution margin after ad spend, and check total store revenue and new-customer orders alongside platform ROAS. A campaign that reports a higher ROAS by absorbing brand searches may be adding less real profit.

Know your break-even ROAS before you start. Our guide to what a good ROAS looks like for an Australian ecommerce store walks through the calculation.

What do both campaign types need before they can work?

Neither campaign type can fix a weak foundation. Three things decide results more than the choice of campaign itself:

• A clean product feed. Titles that use the words customers actually search, accurate prices and availability, good images and no disapproved products. If products are stuck, start with fixing disapproved products in Google Merchant Centre.
• Accurate conversion tracking. Duplicate or missing purchase events mislead every automated bid strategy. Verify tracking before trusting any ROAS figure; our guide to setting up Google Ads conversion tracking covers how.
• Margin awareness. Bidding towards revenue alone treats a low-margin sale like a high-margin one. Build margin into your structure through custom labels or separate campaigns.

Which should your store choose? A simple framework

Your situation	Sensible starting point
New store, limited budget, few conversions	Standard Shopping, plus a small brand Search campaign
Steady conversions and solid tracking, but little creative	Standard Shopping for core products; test Performance Max on best sellers
Steady conversions, solid tracking, good imagery and video	Performance Max on proven products; Standard Shopping for low-data or thin-margin lines
Scaling, and search demand is capped	Performance Max for prospecting, with brand exclusions and regular search term reviews

Whatever you choose, treat it as a hypothesis to test rather than a permanent setting, and revisit the split as your conversion volume, catalogue and creative change.
