# Function overview Recommendation item boosting and demotion is a manual intervention feature that allows operators to adjust the weight factors of specific items to increase or decrease their ranking priority in the recommendation system. This feature provides a direct and effective way to influence recommendation results to meet specific business operation needs. ## Key features * Boost configuration: Increase the recommendation weight for specified items to make them more likely to appear in recommendation results. * Demotion configuration: Decrease the recommendation weight for specified items to make them less likely to appear in recommendation results. * Weight factor: Supports configuring an integer weight factor from \-100% to 100%. The larger the value, the more significant the boosting or demotion effect. ## Typical use cases * New product promotion: Increase exposure for newly listed products by boosting them to enhance their recommendation probability. * Inventory clearance: accelerate the sale of overstocked items by increasing their ranking weight to boost recommendation chances and promote sales. * Negative product suppression: reduce the exposure of products with negative feedback or quality issues by lowering their ranking weight in recommendation results. --- # Configuration steps ## Add new rule The system does not support priority configuration. When an item matches multiple configurations, the platform combines the ranking weight increases and decreases from all configurations to calculate the final weight factor. For example, if item A matches a "boost 50%" rule and a "demote 30%" rule, the platform will ultimately increase the item's weight by 20%. Follow the steps below to apply weight boost or demote to specific items: 1. Go to **"Experience Center" — "Recommendation Experience" — "Strategy"** and click "**Boost or Demotion**" to enter the weight adjustment configuration area.

2. After entering the rule configuration page, please fill in the following information:

|**Configuration item** |**Description** | |---|---| |Rule name |Enter a simple and clear name. | |Scop |Select the target field and effect logic in the item dataset. For example, to boost all items categorized as "shoes," select the field "category," set the effect logic to "equals," and enter the value "shoes." You can add effect logic according to business needs. | |Boost/demotion configuration |Supports configuring an integer weight factor from \-100% to 100%. The larger the number, the more significant the boost or demotion effect. | 3. Click "OK" to create a new rule on the platform. The new boost and demotion rules will take effect in the next recommendation request within the experience interface. 4. Note that previous operations only take effect in the "Experience Center" and are used for preview and testing. After confirming the effect is correct, click the "Sync Changes to API" button to officially apply the rule changes to the online service. ## View existing rules The platform displays the boost and demotion rules effective in this recommendation scenario, and you can view detailed configuration information for each rule. Follow the steps below to view the active boost and demotion rules: 1. You can view promotion and demotion configuration rules under **"Experience Center" — "Recommendation Experience" — "Strategy" — "Boost and Demotion"** .

2. Hover over the rule you want to view, then click the "Edit" button that appears.

## Edit existing rules Edit boost and demote configurations by following these steps: 1. You can view the boost and demote configuration rules in **“Experience Center” — “Recommendation Experience” — “Strategy” — “Boost and Demotion”** .

2. In the rule list, find the rule you want to modify, then click its corresponding “Edit” button.

3. On the opened rule editing page, you can modify the following information:

|**Configuration item** |**Description** | |---|---| |Rule name |set a simple and clear name | |Scope |select the target field and effective logic in the item dataset for example, to boost all items categorized as "shoes," select the field "category," set the logic to "equals," and enter the value "shoes" effective logic can be added according to business needs | |Boost/demotion configuration |supports configuring an integer weight factor from \-100% to 100%; the larger the value, the stronger the boosting or demotion effect | 4. Click “OK,, and the platform will update the rule configuration. The updated boost and demotion rules will take effect in the experience interface during the next recommendation request. 5. Note that previous operations only take effect in the “Experience Center” for preview and testing purposes. After confirming the effect is correct, click the “Sync Changes to API” button to apply this rule change officially to the live service. ## Delete rule Follow these steps to delete a boost and demote rule: 3. You can view promotion and demotion configuration rules in **"Experience Center"—"Recommend Experience"—"Strategy"—"Boost and Demotion"** .

1. Click the target rule's "Delete" button, then click "OK" again in the pop\-up confirmation dialog.

2. Once confirmed, the rule will be deleted immediately. Deleted rules cannot be restored. 3. After deletion, the rule becomes invalid immediately, and the experience interface will no longer use the rule in the next recommendation request. --- # Frequently Asked Questions **Q: Why is there a difference between the recommended results on the experience interface and the online version?** A: The recommended results on the experience interface are preview effects only. The actual online recommendations to users may vary due to personalized recommendations. **Q: Why don’t I see any difference after configuring the rule?** A: If you do not observe the expected effect, please check: 1. Does the "Scope" in the rules meet business expectations? 2. Is the weight factor set reasonably (the higher the value, the stronger the effect)? **Q: Why is my configuration no longer editable?** A: Previous configurations using "Launch time" or "timestamp" attributes for boosting or demotion compatibility with new features are unsupported for editing and can only be deleted. The configuration remains effective until it is deleted. --- # Related documents 1.
