A pet supplies retailer in Morley came to us spending $3,200 per month on google search ads. Text ads, broad match keywords, sending every click to their homepage. Their return on ad spend sat at 1.4x, which meant for every dollar they put in, they got $1.40 back. After product costs, shipping, and our management fee, they were losing money on paid advertisements and did not realise it. The owner thought the campaigns were working because the revenue number looked acceptable in isolation. It was not until Ben sat across from her in their Osborne Park office, pulled up the actual margins per product category, and showed her the gap between ad spend and profit that the reality landed. She went quiet for about ten seconds. Then she said something we hear more often than you would expect: “So what have I been paying for?”
We moved her entire budget into google shopping ads within a fortnight. Rebuilt her product feed from scratch. Took proper product image shots of her top 40 SKUs instead of using the manufacturer stock photos every competitor was running. Wrote product titles that matched actual search queries rather than internal inventory names. Within three months, return on ad spend climbed to 4.7x. Same monthly budget. Shopping ads put her actual products in front of people with high purchase intent at the moment they were comparing options, instead of hoping a text ad and a homepage would do the convincing.
That is the core of why google shopping ads work for Australian retailers. They display your product image, price, store name, and product ratings directly in google search results before a single click happens. The buyer has already seen what you sell and what it costs before they reach your online store. That visual pre-qualification compresses the decision process and filters out people who were never going to buy at your price point.
How Google Shopping Ads Work
Google shopping ads operate on a fundamentally different logic than google search ads. With search ads, you bid on relevant keywords and write text ads that appear when someone searches those terms. With shopping ads, you do not bid on keywords directly. Instead, Google matches your product data to search queries automatically. This distinction trips up retailers constantly: shopping ads are driven by your structured data feed, not keywords.
The process starts with your google merchant center account. This is where your product feed lives, a structured file containing your product titles, product details, pricing, availability, product categories, and product image URLs for every item you want to advertise. Google reads this feed and matches your products to product related searches across Google Search, the shopping tab, google images, and search partners.
When you set up shopping campaigns in your google ads account, you are telling Google how much you are willing to pay when someone clicks on your product listings. But which searches trigger your ads depends on the quality of your product data, not on a keyword list you build manually. This is why we tell every retailer the same thing: your structured feed is the most important element in the entire system. A mediocre feed with a large budget will lose to a precise, detailed feed with a modest daily budget. We have watched it happen dozens of times.
Types Of Google Shopping Campaigns
There are three main campaign types available, and choosing the wrong one is a reliable way to burn through budget before you learn anything useful.
Standard Shopping Campaigns give you the most control. You set your own bids at the ad group level, choose which products to include, set campaign priority when running multiple campaigns, and decide where your ads appear. You can structure your first ad group around your highest margin products and build from there. Standard shopping campaigns suit retailers who want granular control over bid strategy and who have the campaign management resource to optimise regularly. For most retailers starting out, this is where we begin, because the transparency lets you understand what is working before you hand decisions to an algorithm.
Smart Shopping Campaigns use automated bidding and machine learning to set bids and placements across Google Search, the google display network, YouTube, and Gmail. You set a daily budget and a target return on ad spend, and Google’s algorithm handles the rest. Smart shopping removed much of the manual control, which made some retailers nervous and others relieved. Smart bidding performs well when you have enough conversion data to learn from, typically 30 conversions in the past 30 days. Below that threshold, the machine is guessing with your money.
Performance Max Campaigns have largely replaced smart shopping as Google’s preferred automated campaign type. A performance max campaign runs your product ads across every Google channel, including Search, Display, YouTube, Discover, Maps, and Gmail. Performance max ads use your feed from merchant center along with any additional creative assets you provide. The trade-off mirrors smart shopping but amplified: broader reach, less visibility. When performance max works, it scales well. When it misfires, diagnosing why is genuinely frustrating because Google restricts which search queries and channels you can see in reporting.
Our recommendation for most Australian retailers: start with standard shopping to build baseline data and understand which products convert. Then test performance max as a separate new campaign alongside it, rather than replacing what is already profitable.
Setting Up Your Google Merchant Center Account
Your merchant center account is where the entire machine draws its intelligence. If the data going in is lazy, everything downstream suffers.
Start by creating your google merchant center account and verifying your online store domain. Then build or connect your product feed. Most Australian retailers using Shopify, WooCommerce, or BigCommerce can generate a feed automatically through plugins, but the default output is almost never good enough. Auto-generated product titles typically pull internal product names, which rarely match how potential customers actually search. A retailer in Cannington we onboarded last year had 600 products in their feed and 580 had titles no human would ever type into Google. Fixing those titles alone doubled their click-through rate before we touched a single bid.
Your product titles should front-load the most important attributes: brand, product type, key feature, size, colour. “Royal Canin Medium Adult Dry Dog Food 15kg” outperforms “Medium Adult Dog Food” because it matches the specific search queries buyers actually type. Your product details and descriptions should include the relevant keywords people use when searching, written naturally rather than stuffed. Your product image must be clean, well-lit, and show the product against a white or neutral background. Strong images consistently produce higher click-through rates and lower cost per click.
Product categories should match Google’s taxonomy as precisely as possible. Broad categorisation forces Google to guess where your product fits. Tight categorisation means accurate matching to the right searches.
Optimising Your Shopping Ads For Better Performance
Once your campaigns are live and your structured feed is solid, optimisation is where profitable retailers pull away from everyone else bleeding budget.
Use Negative Keywords Aggressively. Even though shopping ads are not keywords driven in the traditional sense, you can still add negative keywords to prevent your ads showing for irrelevant search queries. Check your search queries report weekly. If you sell premium dog food and your ads are triggering for “cheap dog food” or “free dog food samples”, add those as negatives. Every irrelevant click is wasted budget that could have gone toward more qualified leads. One pet retailer we manage was haemorrhaging $400 per month on clicks from people searching for free samples. That is $4,800 per year on people who never intended to spend a cent.
Structure Campaigns By Product Performance. Do not dump every product into a single ad group. Segment by product categories, margin levels, or performance tiers. Your best sellers with strong conversion rates deserve higher bids. Products that generate clicks but not sales need lower bids or exclusion. This sounds elementary but we audit google ads accounts regularly where retailers have hundreds of products in one undifferentiated campaign wondering why results are flat.
Leverage Campaign Priority Settings. When running multiple campaigns targeting the same product, campaign priority determines which bid is used. Run a high-priority campaign with low bids to capture cheap clicks on broad queries, and a low-priority campaign with higher bids to compete on specific, high-converting search queries. This lets you control ad spend precisely across different levels of search intent.
Optimise Your Landing Page. Getting the click means nothing if your landing page, typically the product page on your online store, loads in four seconds, looks like it was built in 2014, or shows a different price than the ad. The product page should display the same product image, the same price, clear stock availability, and a frictionless path to purchase. We rebuilt the product pages for a homewares retailer in Subiaco and their conversion rate from shopping ads went from 1.8 percent to 3.4 percent without changing their ad spend at all. That is not a marginal improvement. That is the same traffic producing nearly twice the revenue.
Free Product Listings And How They Fit In
Google now offers free product listings alongside paid advertisements in the shopping tab and across google search results. If you have a merchant center account with an active feed, your products can appear in free listings without any ad spend. These placements carry less visibility than paid shopping campaigns, but they generate real website traffic at zero cost.
We have seen free product listings account for 8 to 15 percent of total shopping traffic for retailers with well-optimised feeds. For a retailer doing $30,000 monthly through shopping ads, that is $2,400 to $4,500 worth of equivalent traffic arriving for free. Small retailers hesitant about paid campaigns should start here. Get your feed right, appear in free listings, and use that early data to decide whether scaling into paid placements makes sense.
To maximise free listings, the same discipline applies: strong product titles, accurate product data, quality product image assets, and correct categorisation. Google uses the same feed for both paid and free placements, so every improvement to your data quality lifts performance across both channels simultaneously.
Local Inventory Ads For Brick And Mortar Retailers
If you have a local store as well as an online presence, local inventory ads let you show potential customers that a specific product is available at your physical location near them. When someone searches for a product and your local inventory shows you have it in stock, Google can display your ad with a “pick up today” or “in store” label.
Local inventory ads require additional setup in your google merchant center, including a local inventory feed that syncs your in-store stock levels. The effort is real, but for retailers with foot traffic strategies, the results compound. A bike shop in Fremantle we work with generates 35 percent of their google shopping revenue from local inventory ads because cyclists searching for specific components want them today, not in three to five business days. The owner told us his Saturday foot traffic has noticeably increased since we activated local ads, and those walk-in customers often buy accessories they never searched for online. That secondary spend never shows in your ads reporting, but it shows in the till.
What Google Shopping Ads Cost Australian Retailers
Cost varies by industry, competition, and how well your campaigns are built. Average cost per click for shopping ads in Australia ranges from $0.30 to $1.50 for most retail categories. Competitive sectors like electronics and fashion sit higher. Niche products with less competition can run well below $0.50 per click.
The metric that matters is not cost per click. It is return on ad spend and conversion value relative to your actual margins. A $1.20 click that converts into a $180 sale at 40 percent margin is enormously profitable. A $0.35 click on a $12 product at 15 percent margin loses you money after shipping. Understanding your unit economics per product is what allows you to set a bid strategy and daily budget that produces more sales rather than impressions in a report nobody reads.
We manage shopping campaigns for retailers across Perth spending $1,500 to $25,000 monthly. Budget matters less than structure. Retailers with smaller budgets and clean feeds consistently outperform larger retailers running sloppy campaigns. Westside Auto Wholesale does not run traditional shopping ads since they sell used cars from their lot on Ewing Street in Bentley rather than retail products, but the principle we applied to their paid campaigns holds here too: precision in data and targeting beats raw spending power.
How Do Google Shopping Ads Work?
Google shopping ads work by matching your feed data to user search queries. You upload product data to your google merchant center account, create ads through shopping campaigns in your google ads account, and Google displays your product listings, complete with product image, price, and store name, in google search results, the shopping tab, and google images. You pay when someone clicks, not when they see the ad.
Are Google Shopping Ads Better Than Search Ads?
For retailers selling physical products, shopping ads typically outperform text ads because they show the product visually before the click. Buyers see the product image, price, and star ratings, which pre-qualifies them and generates more qualified leads. Search ads still work well for services or products that benefit from descriptive ad copy, but for ecommerce, shopping ads consistently deliver higher conversion rates at lower cost per click.
How Much Should I Spend On Google Shopping Ads?
Start with a daily budget you can sustain for at least 90 days. For most Australian retailers, $30 to $100 per day is a reasonable starting point. This gives you enough data to understand which products convert, what your return on ad spend looks like, and where to increase sales by reallocating budget. Underspending prevents the algorithm from learning. Overspending without data wastes money.
What Is The Difference Between Standard Shopping And Performance Max?
Standard shopping campaigns give you manual control over bids, ad group structure, negative keywords, and campaign settings. Performance max uses automated bidding to promote products across all Google channels with minimal manual input. Standard shopping is better for retailers who want control and transparency. Performance max suits retailers with strong conversion data who want to scale. Many retailers run both as separate campaigns to balance control with reach, using campaign priority to manage overlap.
