What Is a Shopping Campaign?
A Shopping campaign is the primary paid advertising format for e-commerce businesses on Google. Rather than targeting keywords with text ads, Shopping campaigns are driven by a product feed: a structured data file submitted to Google Merchant Center containing each product's title, description, image URL, price, availability, and unique identifier. Google matches the products in your feed to relevant search queries and decides when and where to show your Product Listing Ads (PLAs).
The visual format of Shopping ads is a significant advantage. Each ad shows a product image, title, price, and store name before a user even clicks, which means shoppers self-qualify before arriving at your website. Users who click a Shopping ad have already seen the product and price, resulting in typically higher conversion rates compared to standard text ads for the same search intent. For South African online stores pricing products in rand, accurate and current pricing in the Merchant Center feed is essential for ad approval and buyer trust.
There are two main types of Shopping campaigns available in Google Ads. Standard Shopping campaigns give advertisers direct control over bidding at the product group level, allowing precise management of bids for high and low margin products. Performance Max campaigns, which replaced Smart Shopping in 2022, take a more automated approach by combining product feed data with audience signals and creative assets to serve ads across all of Google's channels simultaneously.
The quality of a Shopping campaign depends heavily on the quality of the product feed. Titles that include key attributes, such as brand, product type, size, colour, and model number, significantly improve match rates. An e-commerce store in Johannesburg selling sneakers should title a product "Nike Air Max 270 Men's Sneakers White Size 10 South Africa" rather than simply "Nike Sneakers", as the more specific title matches a far wider range of commercial queries.
Shopping Campaign In Practice
The scenario below is an illustrative example, not a Juicy Designs client result. It shows the kind of effect that Shopping campaign work typically produces, so treat it as indicative rather than measured.
Picture a Pretoria-based online outdoor and camping equipment retailer running Standard Shopping campaigns segmented by product category: tents, sleeping bags, cooking equipment, and clothing. High-margin categories like tents would carry higher bids. The retailer could use custom labels in the product feed to tag items as "seasonal", "new arrival", or "clearance", then adjust bids per label so end-of-season clearance stock does not compete with full-price featured products.
During the Cape Town Cycle Tour and Comrades Marathon periods, demand spikes for specific cycling and running gear. The retailer might adjust bid multipliers upward for those product categories during the three weeks surrounding each event. The Shopping campaign's search term report would typically surface unexpected queries like "lightweight tent under R2,000" and "gas cooker for camping South Africa", which the team could work into the feed's product titles to improve future match relevance. This kind of continuous feed optimisation is what separates high-performing South African Shopping campaigns from those that merely run.
What a Shopping campaign is
A Shopping campaign is a type of Google Ads campaign that promotes products through visual product listings, showing the product's image, title, price and store name directly in search results and across Google's shopping surfaces, rather than through text ads. When someone searches for a product, Shopping ads can appear as image-led listings (often in a carousel or grid) displaying the product photo, price and retailer, which is highly effective for ecommerce because shoppers see the product and its price before clicking, arriving with clear intent. Shopping campaigns work differently from text search campaigns: instead of bidding on keywords and writing ad copy, Shopping ads are driven by a product data feed (supplied through Google Merchant Center), and Google decides which products to show for which searches based on that feed data and the searcher's query, so the feed, not keywords, is the primary driver. This makes product data quality, the titles, images, prices, descriptions and attributes in the feed, central to Shopping performance. Shopping campaigns are managed in Google Ads (increasingly through Performance Max, which incorporates Shopping across Google's surfaces), with bidding, budgets and settings controlled there, while the products come from the Merchant Center feed. Understanding Shopping campaigns matters for any ecommerce business, because they are a primary way to advertise products on Google, putting visual, price-led product listings in front of shoppers with buying intent, and because their reliance on a product feed makes feed quality, rather than keyword bidding alone, the key lever of success.
Running a Shopping campaign
Running a Shopping campaign requires two connected pieces: a Google Merchant Center account holding the product data feed, and a Google Ads account (linked to it) where the campaign, bidding and budget are managed. Merchant Center is where the product feed lives, the structured data of your products (titles, images, prices, availability, descriptions, identifiers and attributes), which must meet Google's requirements and policies, so setting up Merchant Center and supplying a compliant, quality product feed is a prerequisite, since Shopping ads cannot run without it. The Ads account then uses that feed to run the Shopping (or Performance Max) campaign, where you set budgets, bidding and settings. Because the feed drives which products show for which searches, feed quality, strong, descriptive product titles, good images, accurate prices and availability, complete attributes, is the main determinant of performance, more so than in keyword-based campaigns, which is why shopping feed optimisation is central to Shopping success. Products and the store must also meet Google's Shopping policies and, typically, have a functioning ecommerce site with clear pricing, checkout, and required policies (returns, contact, secure payment). Shopping campaigns are available to ecommerce businesses in many countries, including South Africa, so South African online stores can run Google Shopping ads, provided they set up Merchant Center with a compliant feed, meet the policies, and link it to Google Ads. For a South African ecommerce business, the practical path is to set up Merchant Center and supply a well-optimised product feed, ensure the store and products meet Google's requirements, link to Google Ads, and run the Shopping (or Performance Max) campaign, then focus heavily on feed quality, since that is what most drives which products show and how well they perform, making Shopping campaigns an effective, intent-led way to advertise products online.
FAQ
Do I need Google Merchant Center to run Shopping campaigns?
Yes. Google Merchant Center is required for Shopping campaigns. You submit a product feed containing your product data, including titles, descriptions, prices, images, and GTINs. Google uses this feed to determine which searches trigger your ads. A well-optimised feed with accurate, descriptive product titles and current pricing is fundamental to Shopping campaign performance.
Can South African e-commerce stores run Google Shopping ads?
Yes. Google Shopping is available in South Africa. South African retailers must set up a Google Merchant Center account with their business details, link it to Google Ads, and submit a product feed priced in rand. Ensuring accurate product data and meeting Google's feed quality requirements is critical for getting ads approved and running successfully.
Do you need Google Merchant Center to run Shopping campaigns?
Yes. Shopping campaigns are driven by a product data feed that lives in Google Merchant Center, so you need a Merchant Center account with a compliant, quality product feed, linked to your Google Ads account, to run Shopping (or Performance Max Shopping) ads. Without the Merchant Center feed there are no products for the campaign to show, which is why setting up Merchant Center with a good feed is a prerequisite for Shopping advertising.
