Google Shopping ads — the product listings that appear at the top of Google with images, prices, and store names — are one of the highest-converting ad formats available for South African online retailers. Here's how to set them up and make them work.
How Google Shopping Works
Unlike text-based Google Ads where you choose keywords to bid on, Shopping ads are driven by your product data feed. You submit a feed of all your products (with titles, descriptions, prices, and images) to Google Merchant Centre, and Google automatically matches your products to relevant searches. The ads appear at the top of search results for product-intent queries.
Setting Up Google Shopping in South Africa
- Create a Google Merchant Centre account at merchants.google.com — verify and claim your website
- Set up your product feed — this can be done manually (for small catalogues), via a Shopify/WooCommerce plugin, or via a Google Sheets template
- Ensure your feed meets Google's requirements: accurate pricing, in-stock status, clear titles, and compliant images (no watermarks, white backgrounds for most categories)
- Link Merchant Centre to your Google Ads account
- Create a Shopping campaign in Google Ads targeting South Africa
Product Feed Optimisation
Your product feed is the engine of your Shopping campaigns. Poor feed quality = poor performance. Key optimisation areas:
- Product titles: Include brand, product type, key attributes (colour, size, material) — "Nike Air Max 90 White Running Shoes Mens Size 10 SA" outperforms "Running Shoe"
- Product descriptions: Use relevant search terms naturally; describe what makes the product unique
- GTIN numbers: Include Global Trade Item Numbers (barcodes) for branded products — improves eligibility and performance
- Images: High-quality, white background for core image; lifestyle images in additional image slots
Shopping Benchmarks for SA E-Commerce
| Metric | SA Benchmark |
|---|---|
| ROAS (Return on Ad Spend) | 300% – 800% |
| Cost per click | R3 – R25 |
| Conversion rate | 1% – 4% |
Performance Max vs Standard Shopping
Google has largely moved to Performance Max (PMax) campaigns which incorporate Shopping inventory alongside Search, Display, and YouTube. PMax uses AI to optimise across all channels but requires more budget and time to learn. Standard Shopping campaigns give more control and transparency — recommended for most SA e-commerce businesses starting out with a modest budget.
