1. Before installation
Install and connect Shopify's official Google & YouTube app. Prosper Custom Labels does not configure the Google channel for you.
2. Open Prosper Custom Labels
On first open, the app checks custom_label_0 through custom_label_4. Missing compatible product metafield definitions are created automatically. Resolve any incompatible-definition warning before publishing that slot.
3. Name a slot
Use an internal purpose such as Promotion tier, Season, Margin band, Stock status, or Campaign group. Google receives only each case's output value.
4. Add cases in priority order
Start with the narrowest outcome. Use concise, stable values such as clearance, sale, new_30d, high_margin, or winter.
5. Build rules
Combine ALL, ANY and NONE groups across product dates, pricing, inventory, tags, variants and metafields. Variant conditions explicitly match any, all or no variants. A product stops at its first matching case.
6. Preview
Review scanned, set, clear, unchanged and per-case counts. Check sample current and desired values. Preview never writes.
7. Publish
Publishing activates ownership of the selected slot. Product and inventory updates re-evaluate active rules, while scheduled reconciliation catches missed events and rolling-date changes.
8. Verify the official editor
Open Shopify's Google & YouTube product editor and confirm the custom-label column. Channel-side processing time remains controlled by the official app and Google.
9. Pause safely
Pause to stop future writes without deleting current values. Edit, preview and republish when ready.
