A working Shopping campaign starts with a clean product feed. Here’s the end-to-end setup that prevents disapprovals and drives sales.
What Shopping Ads Are
Shopping Ads are product-level ads that show a photo, price, and store name directly in Google search results. They sit above text ads for product queries and convert 2–3x better because buyers see what they’re getting before they click. Unlike text ads, you don’t bid on keywords — Google uses your product feed data to match your products to relevant searches automatically.
Step 1: Set Up Merchant Center
Go to merchants.google.com and create an account. Verify and claim your website URL, add business info (legal name, address, phone), and configure shipping and return policies for each country you sell to. This is where most accounts get stuck: shipping setup must match the currency of your product prices, or Google disapproves every product for currency mismatch.
Step 2: Build the Product Feed
Your product feed is the fuel for Shopping Ads. Minimum required fields: id, title, description, link, image_link, availability, price, brand, gtin (if applicable), condition. Use all 150 characters of the title and 5,000 of the description — they directly affect which searches your product matches. Shopify, WooCommerce, and BigCommerce have free apps that auto-build and sync the feed.
Step 3: Create the Shopping Campaign
In Google Ads, create a new campaign, choose ‘Sales’ goal and ‘Shopping’ type. Link your Merchant Center account. Set bidding to Manual CPC for the first 2–4 weeks while you gather data, then consider Target ROAS once you have 30+ conversions. Split into priority levels only if you need to exclude certain products; most accounts run one priority-0 campaign with all products.
Step 4: Feed Hygiene and Approvals
Check Merchant Center diagnostics daily for the first 2 weeks. Common disapprovals: missing shipping, currency mismatch, broken image URLs, missing GTINs. Fix approvals before scaling — a campaign with 50% disapproved products is bidding on a quarter of what it should be. Target 95%+ approval rate and keep it there. Use automatic item updates to let Google re-crawl product pages and update prices/availability.
Step 5: Optimize for Profit, Not Just Clicks
Shopping campaigns look good on impressions and terrible on margin if you don’t optimize. Add negative keywords (yes, Shopping uses negatives) to block generic informational queries. Exclude unprofitable products with product groups and negative bid adjustments. Monitor margin by product — some of your best-selling products may be the worst for profit. Pull a monthly profit-by-product report and act on it.
