Overall Brand Performance Score

Calculates a single composite score for each brand combining multiple performance dimensions into one unified health metric. The composite score aggregates awareness, positioning, sentiment, and recommendation metrics into one normalized number (typically 0-100). Higher scores indicate better overall brand performance. This holistic metric simplifies brand comparison and provides executives with one number that captures complete brand health. Perfect for dashboards, rankings, and high-level strategic decisions. **When to use:** User wants overall brand rankings, needs one score for all brands, requires simplified performance comparison, wants executive summary metrics, or needs to identify top/bottom performers quickly. **Common user queries:** - "What's the overall score for each brand?" - "Rank brands by composite score" - "Which brand performs best overall?" - "Show me brand health scores" - "Get summary performance metrics" - "Compare brands with one number" **Returns:** Array of brands with their composite performance scores and optional time period breakdowns. Example: [{"brand": "Nike", "composite_score": 85.5}, {"brand": "Adidas", "composite_score": 72.3}] **Note:** At least one of `brand` or `brand__in` must be provided.
