Quick answer: Google Shopping ads pull product data from a Merchant Center feed. You need two accounts, a clean product feed, and high-resolution jewelry images. Setup takes less than an hour once your data is ready.
What Are Google Shopping Ads for Jewelry Stores?
Google Shopping ads show your product image, title, price, and store name right inside search results. No manual ad copy. Your product data does the work.
How Shopping ads differ from text ads
Text ads need keywords and written headlines you craft yourself. Shopping ads use product attributes from your feed. Google matches your jewelry to relevant searches automatically.
Why jewelry stores benefit from product image ads
Jewelry is visual. A photo of a diamond solitaire ring converts better than a text link. Shoppers compare styles and prices before they ever click.
Where Shopping ads appear
Per Google's Ads Help Center, Shopping ads run across Google Search, Google Images, Maps, Gmail, YouTube, and the Display Network. That is wide reach from one campaign.

How to Create Google Shopping Ads: The Full Setup
Per Google's Shopping campaigns documentation, you need two accounts working together: Google Merchant Center and Google Ads. Follow these five steps.
Step 1: Set up a Google Merchant Center account
Go to merchants.google.com. Create an account and verify your store domain. This is where your product data lives.
Step 2: Upload your jewelry product feed
Build a spreadsheet or connect an automated feed. Required fields include: id, title, description, link, image_link, price, availability, condition, brand, and gtin (or mpn). For jewelry, also add material and metal type. Submit the feed through Merchant Center.
Step 3: Link Merchant Center to Google Ads
Inside Merchant Center, go to Settings, then Linked Accounts. Connect your Google Ads account. Both accounts must be active before you create a campaign.
Step 4: Create a Shopping campaign
In Google Ads, click New Campaign. Choose Sales or Leads as your goal. Select Shopping as the campaign type. Pick Standard Shopping for manual control or Performance Max for AI-driven reach across all channels. Note: Smart Shopping campaigns were deprecated in 2022. Do not reference them as an option.
Step 5: Configure product groups and bidding
Product groups let you set different bids by category, brand, or price range. Start with All Products at a conservative bid. Split into groups once you have performance data.

Product Image Requirements for Jewelry Ads
Your images determine whether your feed gets approved. Blurry or misleading photos violate Google's image quality policy and can get your feed disapproved.
Current image size requirements (100x100 minimum, 500x500 recommended)
Per Google Merchant Center's image_link documentation, the current minimum is 100x100 pixels for non-apparel products. Google recommends at least 500x500 for better display quality.
January 2027 enforcement: new 500x500 minimum
Starting January 31, 2027, all products must meet a 500x500 pixel minimum. Shoot high-resolution images now. Waiting will create feed problems at a bad time.
Best practices for jewelry photography in Shopping ads
Use a clean white or neutral background. Show the full piece clearly. Avoid lifestyle-only shots as your main image. Google's image policy requires the product to be clearly visible and accurate.
Using additional images to showcase variants
Merchant Center supports an additional_image_link attribute. Upload alternate angles, lifestyle context, or close-up detail shots here. These appear in expanded product panels and help shoppers explore your pieces.

Handling Jewelry Variants (Metal Types, Stones, Sizes)
Structuring customized products in Merchant Center
Per Google Merchant Center's best practices for customized products, jewelry with different settings and stones should be structured as separate product variants. Each variant needs its own SKU and product data entry.
Product attributes Google needs from jewelry stores
Include color (metal tone), material (gold, silver, platinum), size, pattern (setting style), and gemstone type. More complete attributes mean more relevant placements.
Variant management: one product vs. multiple SKUs
Multiple SKUs give you cleaner bid control. You can bid more aggressively on a best-selling 14K gold ring and conservatively on a slower-moving variant.

Optimize Your Shopping Campaign
Selecting Standard Shopping vs. Performance Max
Standard Shopping gives you full control over product groups and bids. Performance Max uses Google's AI to place ads across Search, Display, YouTube, and more. Start with Standard Shopping. Test Performance Max once you have conversion data to inform the AI.
Product groups and bidding strategies
Organize product groups by jewelry category first: rings, necklaces, earrings, bracelets. Then split by price tier. Higher-price items typically warrant higher bids and deserve their own group.
Using Brand Profile to maintain visual consistency
Coinis Brand Profile learns your brand's visual identity and tone. When you generate or refresh product images with Coinis Image Ads, every output matches your store's look. Consistent visuals across your entire jewelry catalog build shopper trust. Strong creative is what fills the feed with images worth clicking.

Frequently Asked Questions
Do I need a Google Merchant Center account to run jewelry ads on Google?
Yes. Google Shopping ads pull data directly from your Merchant Center product feed. You cannot create Shopping ads without one. Both Merchant Center and Google Ads accounts are required, and they must be linked before you launch a campaign.
What image size do I need for Google Shopping jewelry ads?
Today the minimum is 100x100 pixels. Starting January 31, 2027, Google requires at least 500x500 pixels for all products. Google recommends 500x500 or larger right now for better ad display quality. Plan ahead with high-resolution product photography.
Should I use Standard Shopping or Performance Max for my jewelry store?
Start with Standard Shopping. It gives you full control over product groups and bids while you learn what works. Once you have conversion data, test Performance Max to let Google's AI optimize placements across Search, YouTube, Display, and more.
How do I handle jewelry variants like different metal types or gemstones?
Per Google Merchant Center's best practices for customized products, each variant should be its own product entry with its own SKU. Include attributes like color, material, size, and gemstone type. This gives Google the data it needs to match each variant to the right shopper.
