A better Shopping feed is usually the result of many small structural improvements, not one magic field.
Start with Merchant Center diagnostics
Separate disapprovals and eligibility problems from optimisation opportunities. Fix blocking issues first, then work on quality improvements such as titles, taxonomy and images.
Keep IDs stable
Product IDs should remain consistent when the product is updated. Changing IDs unnecessarily can break continuity across downstream systems and reporting.
Improve titles using real product attributes
Build titles from structured fields such as brand, product type, model, colour, size or material where those attributes genuinely distinguish the product. Google allows up to 150 characters and expects the title to accurately describe the product and match the landing page.
Treat identifiers carefully
GTINs are not optional filler. Google advises merchants not to guess or invent a GTIN. Join trusted supplier or manufacturer data, validate it and flag products where no reliable identifier exists.
Check variants as a group
Variant data should stay consistent across item group, size, colour and other distinguishing attributes. Problems are easier to fix with rules when the source relationships are mapped correctly.
Use product type for your own structure
A controlled internal product_type hierarchy can support reporting and campaign logic even when a separate Google product category is also required.
Validate the final output, not only the source
Mapping and channel-specific rules can introduce new issues. Grade the destination feed immediately before export so the team knows what Google will actually receive.
Feednetic is designed to turn repeatable findings from this kind of audit into mappings, rules, enrichment workflows and validation checks rather than one-off spreadsheet fixes.
