Google Shopping (formerly Google Product Listing Ads) is an advertising format that displays product images, prices, and merchant names directly in Google Search results — either at the top of the page in a horizontal carousel or in the Shopping tab. Unlike text search ads (where advertisers choose keywords to bid on), Shopping ads are served based on a product data feed submitted to Google Merchant Centre. Google matches product data to relevant searches automatically. Shopping ads generate high-intent, comparison-stage traffic and are essential for most UK ecommerce businesses.
Google Shopping has become the primary discovery channel for product searches. When someone searches for 'buy running shoes UK' or 'cheap laptop UK', Shopping ads typically appear before text ads and organic results — making Shopping visibility crucial for ecommerce revenue. Products listed in Shopping must have a Google Merchant Centre account with a product feed that meets Google's data quality standards.
Google Shopping setup requirements
- Google Merchant Centre account — verified with your website domain
- Product data feed — title, description, price, availability, image URL, GTIN/MPN for each product
- Feed quality — accurate, complete product data; feeds with errors or disapprovals do not serve ads
- Performance Max or Shopping campaign — created in Google Ads and linked to Merchant Centre
- Bidding strategy — Target ROAS or Maximise Conversion Value for most established Shopping accounts
- Product titles — the most critical Shopping optimisation; include brand, product type, key attributes in titles
- Product images — high quality, white background preferred, showing the product clearly
Standard Shopping campaigns allow manual control of product groups, bidding, and ad scheduling. Performance Max automatically serves products across Search, Shopping, Display, YouTube, and Gmail based on Google's AI — with less transparency into which channels are performing. For accounts with sufficient conversion data, Performance Max often outperforms Standard Shopping on revenue and ROAS. Standard Shopping is preferable when granular control is needed — specific product exclusions, tight bid management by margin, or separation of branded vs non-branded shopping traffic.
Product titles are the most important Shopping optimisation lever. Google uses title content to match products to search queries. Best practices: include the brand name, product type, key differentiating attributes (colour, size, material, model number) in the first 70 characters of the title (the portion most visible in Shopping listings). For apparel: 'Brand + Product Type + Gender + Colour + Size'. For electronics: 'Brand + Model + Product Type + Key Spec'. Avoid promotional language ('Free shipping', 'Best price') in titles — these are disapproved.
