FAQ
Do I need a feed if I'm not running Shopping ads?
Yes for free Surfaces Across Google (organic shopping placements, Google Search shopping carousel, Image Search shopping results, Google Lens). The free placements use Merchant Center data; a feed unlocks them even without paid Shopping campaigns.
How often should the feed update?
Daily for stores with frequent inventory changes; weekly if your catalog is stable. Real-time updates via the Content API are an option for large catalogs with hourly inventory movement.
What's the most common rejection reason?
Price mismatch between feed and landing page, usually caused by feed being stale or landing page showing a discount that the feed doesn't reflect. Followed by missing GTIN/MPN/brand combination on new products.
Does Ordiko generate Merchant Center feeds?
Yes. Ordiko emits per-store Google Merchant, Bing Merchant, Facebook Catalog, and Pinterest product feeds at /feeds/google-merchant.xml etc. The feeds pull from your live catalog and refresh on cache invalidation.
The feeds pull from the live catalog with cache-tag invalidation on product mutations. All required attributes are emitted from your product schema; optional attributes (color, size, material) auto-populate from variant attributes.
Configure feed-level settings at Settings → Feeds in the dashboard.
