Feed rules let you transform product data inside Merchant Centre without changing the source. They are a fast way to fix gaps, map fields and standardise values, but they work best alongside a clean feed rather than as a permanent patch.
We use feed rules carefully within our Google Merchant Centre service, applying them to shape product data where editing the source is slow or impractical.
A feed rule modifies the data Google reads as it imports your feed. It can map one field to another, set a default value or clean up inconsistent text, all without touching the original source.
Feed rules shine when the source feed is hard to change quickly or needs a consistent transformation across many products.
A feed rule is a transformation layer, not a substitute for clean data. Use rules for mapping and quick fixes, but correct genuine data errors at the source so every channel benefits.
| Situation | Better choice |
|---|---|
| Field naming differs from Google | Feed rule to map the field |
| A value is wrong on the website | Fix the source data |
| Need a consistent default | Feed rule to set the default |
Document every feed rule you create. Undocumented rules make it hard to trace why product data looks different from the source.
This service covers the Merchant Centre feed and product data layer: setup, optimisation, feed rules and disapprovals. Campaign bidding and structure sit with our Google Shopping management. The two work best together.
