Metafields & Syndication
Current Vantage product metafields, merchant-approved writes and external-visibility limits
Last updated: 8th September 2026
Metafields & Syndication
Vantage stores product-data results in app-owned metafields and can apply merchant-approved content proposals. A saved metafield does not prove that an external AI service ingested it, used it for ranking, or recommended the product. Vantage does not verify external syndication or measure AI-search visibility.
Current definitions
Vantage registers 11 product metafield definitions using the $app:vantage namespace identifier. The keys below describe their purposes; registration alone does not mean every product has every value.
| Key | Purpose |
|---|---|
ai_readiness_score | Composite product-data readiness score |
last_optimized | Audit/optimisation timestamp |
ai_title | Product title enrichment |
ai_description | Product description enrichment |
key_features | Structured feature list |
use_cases | Product use cases |
materials | Material information |
certifications | Source-supported certification information |
target_audience | Supported audience information |
comparison_attrs | Structured comparison attributes |
review_signals | Review-derived evidence/signals |
These definitions support the current app. They are not eight reserved future fields alongside two live fields.
When values change
Enabled baseline audits write ai_readiness_score and last_optimized. The Metafield Writing setting controls that audit step.
Selected workflows can prepare enrichment proposals. Growth-or-higher review intelligence can prepare a separate review-signals proposal from supported review data. Inspect source facts and evidence before approving. Saving a proposal for review does not itself approve its Shopify writeback.
Approved content changes can affect an existing product title, description or supported metafield. Image alt-text saves are a separate explicit action. Disabling baseline score/timestamp writes does not disable those merchant-authorized actions.
Access and cleanup
Shopify manages app-owned namespace access. Do not infer external distribution from a storefront-access setting. Check the actual product's metafields when verifying an approved change; a definition is not proof of a populated value.
Uninstall is not a rollback of titles, descriptions or image alt text you approved. Read the privacy policy for app-data deletion and retained-record boundaries; do not assume every provider or backup record disappears immediately.
