Shopping ads are Google ads for physical products that show a photo, the product name, the price and the shop’s name, rather than a written text advert. They are built from the product data you send to Google Merchant Center and you pay when someone clicks.
How Shopping ads work
Text ads start with keywords. Shopping ads start with your products. You upload a product feed to Merchant Center listing every item with its title, description, image, price, availability, brand and identifiers such as the GTIN. You then link Merchant Center to Google Ads and run the products through a Standard Shopping campaign or a Performance Max campaign.
When someone searches, Google reads your product data, mainly the title, description and category, to decide whether an item matches. A search for “oak dining table extending 6 seater” can trigger a listing whose title says “Extending Oak Dining Table, Seats 6 to 8”. You cannot choose keywords; you influence matching through the quality of your data and through negative keywords.
Bids are set on groups of products, called listing groups, which you can split by brand, category, item ID or custom labels such as margin band. The ads appear in the Shopping tab, at the top or side of normal results, in Google Images and, through Performance Max, on YouTube and partner sites.
Why it matters
For an online shop, Shopping ads are often where the buying searches are. Someone who types a specific product name and size is close to purchasing, and the ad shows them the thing itself with its price before they click. That pre-qualifies the click: a person who clicks a £180 listing has already accepted the price.
Three UK specifics are worth knowing. Prices must be in pounds and include VAT, exactly as they appear at checkout. Shops in the UK can choose which comparison shopping service places their ads, a result of the competition rules that apply in the UK and Europe; Google Shopping is one CSS among many, and some others offer a discount on the click cost. And free listings run alongside paid ones, so a well-kept feed earns some unpaid visibility as well.
Common mistakes
- Titles copied straight from the website, such as “The Marlow”, which tell Google nothing about what the product is.
- Bidding the same on every product, so low-margin items take the budget from the profitable ones.
- Ignoring the search terms report, which in Shopping is the main way to spot irrelevant matches.
- Prices or stock that differ between the feed and the site, leading to disapprovals.
- Judging Shopping only on return on ad spend while ignoring returns, delivery costs and margin.
- Low-quality images with text or watermarks over the product, which break Google’s image rules.
How to act on it
Start with the feed, because it is your targeting. Rewrite titles to lead with what the product is, then the key attributes people search for: brand, material, size, colour. Fill in the Google product category and product type, and add custom labels for margin and best sellers so you can bid by profit rather than by revenue.
Then structure campaigns around how much each product is worth to you. Many UK shops run Performance Max for most products and keep a Standard Shopping campaign where they need tighter control. Check the search terms weekly, add negatives, and look at profit per product monthly.
