Wix product feed optimisation for Performance Max Shopping campaigns

The product feed that your Wix Store sends to Google Merchant Center is the data foundation of every Performance Max Shopping campaign. The quality of this feed — how accurately and completely it describes your products — directly determines where, how often, and to whom your PMax ads are shown. Feed optimisation is therefore one of the highest-leverage activities for improving PMax performance, and it simultaneously improves your organic Shopping tab visibility.

How Wix Connects to Google Merchant Center

Wix Stores can connect directly to Google Merchant Center through the Wix Marketing Integrations panel (Dashboard > Marketing > Google Shopping). This connection synchronises your product catalogue as a live feed. Any changes you make to product titles, descriptions, prices, and images in your Wix Store are reflected in the Google Merchant Center feed typically within 24 to 48 hours.

Product Title Optimisation for PMax and Shopping

Product titles in your Wix Store are the most important feed attribute for both Shopping ad relevance and organic Shopping tab ranking. Google's algorithm uses the product title as the primary relevance signal for query matching. Titles should include: brand name, product name, key attributes (colour, size, material), and the primary keyword a buyer would use to search for this product. The standard formula is: Brand + Product Type + Key Attribute + Model/Variation.

• Include the primary keyword your customers search at the start of the title (most important position)
• Add colour, size, or material variant information within the title for filtering relevance
• Avoid promotional language ("SALE", "Best ever") which reduces Google's trust in the title accuracy
• Keep titles under 150 characters but use the available space — more detail generally improves matching
• Mirror the language used in successful organic competitor titles for the same product type
• For bundle products, list the key included items in the title rather than a generic bundle name

Product Description Optimisation

Writing high-performance product descriptions for the feed

• Open each product in your Wix Store editor and review the description for completeness.
• Ensure the first 160 characters of each description contain the most important product information — this section is most prominently used in the feed.
• Include all relevant attributes: materials, dimensions, compatible devices, care instructions, and use cases.
• Add relevant synonyms and alternative terms that buyers might use to search for the product.
• Avoid marketing-speak and focus on factual, specific product information.
• Update descriptions to reflect any product changes, new variants, or updated specifications.
