-
-## Tag Management Best Practices
-
-### Recommended Tag Categories
-
-1. **Campaign Tags**: `"july_us_sale"`, `"black_friday_2024"`, `"spring_launch"`
-2. **Asset Type Tags**: `"hero_image"`, `"product_shot"`, `"lifestyle"`, `"logo"`
-3. **Channel Tags**: `"social_media"`, `"email"`, `"display"`, `"video"`
-4. **Temporal Tags**: `"q1_2024"`, `"seasonal"`, `"evergreen"`
-5. **Performance Tags**: `"best_performer"`, `"testing"`, `"archived"`
-6. **Product Tags**: `"dog_food"`, `"cat_food"`, `"treats"`, `"toys"`
-7. **Audience Tags**: `"gen_z"`, `"pet_parents"`, `"new_customers"`
-
-### Tag Naming Conventions
-
-- Use lowercase with underscores: `"july_us_sale"` not `"July US Sale"`
-- Be specific but not too granular: `"summer_2024"` not `"june_15_2024"`
-- Use consistent prefixes for categories: `"product_dog_food"`, `"product_cat_food"`
-- Avoid special characters except underscores
-
-## Implementation Guide
-
-### Asset Storage Integration
-
-```python
-def add_asset_to_library(library_id, asset_data):
-    # Validate asset data
-    validate_asset(asset_data)
-    
-    # Generate ID if not provided
-    if not asset_data.get('asset_id'):
-        asset_data['asset_id'] = generate_asset_id(asset_data)
-    
-    # Process media if URL provided
-    if asset_data.get('url'):
-        metadata = extract_media_metadata(asset_data['url'])
-        asset_data['metadata'] = {**metadata, **asset_data.get('metadata', {})}
-    
-    # Add timestamps
-    asset_data['created_at'] = datetime.now().isoformat()
-    asset_data['updated_at'] = asset_data['created_at']
-    
-    # Store in library
-    library = get_library(library_id)
-    library.add_asset(asset_data)
-    
-    # Index by tags for fast retrieval
-    index_asset_tags(library_id, asset_data['asset_id'], asset_data.get('tags', []))
-    
-    return asset_data
-```
-
-### Tag-Based Search
-
-```python
-def search_assets_by_tags(library_id, tags, filters=None):
-    library = get_library(library_id)
-    
-    # Get assets with ALL specified tags
-    asset_ids = library.get_assets_with_tags(tags)
-    
-    # Apply additional filters
-    if filters:
-        asset_ids = apply_filters(asset_ids, filters)
-    
-    # Retrieve asset details
-    assets = [library.get_asset(aid) for aid in asset_ids]
-    
-    return assets
-```
-
-### Automatic Tag Suggestions
-
-```python
-def suggest_tags(asset):
-    suggestions = []
-    
-    # Based on asset type
-    if asset['type'] == 'image':
-        if asset.get('metadata', {}).get('width', 0) > 1000:
-            suggestions.append('high_res')
-        
-    # Based on filename/URL
-    if 'summer' in asset.get('name', '').lower():
-        suggestions.append('seasonal')
-        suggestions.append('summer_2024')
-    
-    # Based on upload date
-    quarter = get_quarter(asset.get('created_at'))
-    suggestions.append(f'q{quarter}_2024')
-    
-    return suggestions
-```

-# Creative Library
-
-The AdCP Creative Library provides centralized management for all creative assets at the advertiser/account level. This industry-standard approach eliminates redundant uploads, enables creative reuse across campaigns, and provides better governance and performance tracking.
-
-## Overview
-
-Unlike the traditional model where creatives are uploaded directly to campaigns, AdCP's Creative Library follows the standard approach used by major ad platforms:
-
-1. **Upload Once**: Creatives are uploaded to a central library
-2. **Assign Many**: Library creatives can be assigned to multiple campaigns
-3. **Manage Centrally**: All creative operations happen at the library level
-4. **Track Globally**: Performance and compliance tracked across all uses
-
-This approach mirrors how Google Ad Manager, Meta Business Manager, and other major platforms handle creative assets.
-
-## Quick Start
-
-Ready to start using the Creative Library? Here's the essential workflow:
-
-1. **📤 Upload creatives**: [`sync_creatives`](../task-reference/sync_creatives) - Add assets to your library
-2. **🔍 Find creatives**: [`list_creatives`](../task-reference/list_creatives) - Search and filter your library  
-3. **🎯 Assign to campaigns**: Use assignments in [`sync_creatives`](../task-reference/sync_creatives) or [`create_media_buy`](../task-reference/create_media_buy)
-
-**New to creative management?** Start with the [Creative Lifecycle](./index.md) conceptual overview.
-
-## Library Architecture
-
-### Creative Storage
-
-All creatives are stored at the **advertiser/account level**, making them available for any media buy within that account. Each creative in the library has:
-
-- **Unique Identity**: `creative_id` that remains consistent across all uses
-- **Rich Metadata**: Name, tags, format information, compliance status
-- **Assignment Tracking**: Real-time view of which campaigns use the creative
-- **Performance History**: Aggregated metrics across all assignments
-
-### Assignment Model
-
-Creatives are **assigned** to specific packages within media buys rather than being uploaded directly:
-
-```
-Creative Library
-    ├── Creative A (video_hero_30s)
-    │   ├── Assigned to: Campaign 1, Package A
-    │   └── Assigned to: Campaign 2, Package C
-    │
-    ├── Creative B (display_banner_300x250)
-    │   └── Assigned to: Campaign 1, Package B
-    │
-    └── Creative C (audio_spot_15s)
-        └── Unassigned (available for future use)
-```
-
-## Core Operations
-
-The creative library supports two primary operations:
-
-### 1. Creative Management
-
-Use [`sync_creatives`](../task-reference/sync_creatives) to:
-- Upload new creatives to the library
-- Update existing creative metadata
-- Assign creatives to packages
-- Bulk operations with upsert semantics
-
-**Benefits:**
-- No immediate campaign assignment required
-- Creative available for multiple future uses
-- Validation and approval before assignment
-- Suggested adaptations for better performance
-
-**📋 Get Started:** See the [`sync_creatives`](../task-reference/sync_creatives) technical documentation for detailed examples and parameters.
-
-### 2. Creative Discovery
-
-Use [`list_creatives`](../task-reference/list_creatives) to:

-
-**🔍 Get Started:** See the [`list_creatives`](../task-reference/list_creatives) technical documentation for advanced filtering and querying options.
-
-### 3. Assign (`action: "assign"`)
-
-Connect library creatives to campaign packages:
-
-```json
-{
-  "action": "assign",
-  "creative_ids": ["brand_video_30s", "brand_video_15s"],
-  "media_buy_id": "mb_12345",
-  "package_assignments": ["pkg_ctv_prime", "pkg_ctv_daytime"]
-}
-```

-  "updates": {
-    "click_url": "https://brand.com/spring-sale",
-    "name": "Brand Hero Video 30s - Spring Sale"
-  }
-}
-```
-
-**Applies To:** All current and future assignments of the creative
-
-### 5. Unassign (`action: "unassign"`)
-
-Remove creative from specific campaigns while keeping in library:
-
-```json
-{
-  "action": "unassign",
-  "creative_ids": ["brand_video_30s"],
-  "package_ids": ["pkg_ctv_prime"]
-}
-```
-
-**Preserves:** Creative remains in library for future use
-
-### 6. Archival
-
-Creatives can be archived through [`sync_creatives`](../task-reference/sync_creatives) status updates:
-
-**Options:**
-- **Archive**: Soft delete, preserves for reporting
-- **Delete**: Permanent removal (use with caution)
-
-## Library Organization
-
-### Naming Conventions
-
-Use consistent `creative_id` patterns for better organization:
-
-```
-Format: {brand}_{type}_{duration/size}_{version}
-
-Examples:
-- nike_hero_video_30s_v1
-- nike_display_banner_300x250_v2
-- nike_audio_spot_15s_v1
-```
-
-### Tag Strategy
-
-Organize creatives with meaningful tags:
-
-**Campaign Tags:**
-- `q1_2024`, `holiday_campaign`, `summer_sale`
-
-**Format Tags:**
-- `video`, `audio`, `display`, `mobile_optimized`
-
-**Performance Tags:**
-- `high_ctr`, `approved_creative`, `needs_optimization`
-
-**Brand Tags:**
-- `nike_air`, `nike_jordan`, `brand_logo`
-
-### Status Management
-
-Track creative lifecycle through status values:
-
-- **`approved`**: Ready for campaign assignment
-- **`pending_review`**: Uploaded, awaiting platform approval
-- **`rejected`**: Failed validation, needs revision
-- **`processing`**: Being transcoded or processed
-- **`archived`**: Soft-deleted, preserved for reporting
-

-## Performance & Analytics
-
-### Creative Performance Tracking
-
-Library creatives accumulate performance data across all assignments:
-
-```json
-{
-  "creative_id": "brand_video_30s",
-  "performance_metrics": {
-    "total_impressions": 1250000,
-    "total_clicks": 15750,
-    "average_ctr": 0.0126,
-    "assignments": 3,
-    "campaigns_used": 2
-  }
-}
-```
-
-### Cross-Campaign Analysis
-
-Compare creative performance across different contexts:
-
-- **Format Analysis**: Which video lengths perform best?
-- **Campaign Context**: Does the same creative perform differently across campaigns?
-- **Platform Optimization**: Which adaptations work best on each platform?
-- **Audience Insights**: Creative performance by targeting dimension
-
-## Best Practices
-
-### Upload Strategy
-
-1. **Upload Early**: Add creatives to library before campaign planning
-2. **Version Control**: Use clear version numbers for creative iterations
-3. **Format Planning**: Consider multiple formats (mobile, desktop, audio) during upload
-4. **Tag Consistently**: Use standardized tagging for easy discovery
-
-### Assignment Workflow
-
-1. **Search First**: Check library for existing suitable creatives
-2. **Bulk Assign**: Use batch operations for efficiency
-3. **Monitor Performance**: Track how library creatives perform across campaigns
-4. **Optimize Continuously**: Update click URLs and metadata based on performance
-
-### Library Maintenance
-
-1. **Regular Audits**: Review unused or underperforming creatives
-2. **Archive Outdated**: Remove expired promotional creatives
-3. **Performance Reviews**: Identify top-performing creatives for reuse
-4. **Compliance Monitoring**: Ensure all creatives meet current policy requirements
-
-### Creative Governance
-
-1. **Approval Workflows**: Establish library upload approval processes
-2. **Brand Guidelines**: Ensure all uploads meet brand standards
-3. **Usage Tracking**: Monitor which creatives are being used where
-4. **Performance Standards**: Set minimum performance thresholds
-
-## Migration to Creative Library
-
-If migrating from deprecated creative workflows:
-
-### Step 1: Upload Existing Creatives
-Use [`sync_creatives`](../task-reference/sync_creatives) to add assets to the library:
-```json
-{
-  "creatives": [/* your existing creative assets */]
-}
-```
-
-### Step 2: Assign to Current Campaigns
-Use the `assignments` parameter in [`sync_creatives`](../task-reference/sync_creatives) or create new campaigns with [`create_media_buy`](../task-reference/create_media_buy).
-
-### Step 3: Adopt Library Workflow
-- Use [`list_creatives`](../task-reference/list_creatives) to search before creating new creatives
-- Reuse approved creatives across campaigns
-- Manage all creative operations through the library
-
-## Troubleshooting
-
-### Common Issues
-
-**Creative Not Found**
-- Verify `creative_id` exists in library
-- Check creative status (may be archived)
-- Ensure proper account-level access
-
-**Assignment Failed**
-- Verify media buy exists and is active
-- Check package IDs are valid
-- Ensure creative format matches package requirements
-
-**Performance Discrepancies**
-- Library metrics are aggregated across all assignments
-- Use campaign-specific reporting for individual performance
-- Consider assignment timing when analyzing performance
-
-### Support Resources
-
-- Use [`list_creatives`](../task-reference/list_creatives) to audit current library state
-- Check creative status and assignment history
-- Review platform-specific creative requirements
-- Monitor adaptation suggestions for optimization opportunities

+description: Standardized brand information manifest for creative generation and media buying
+keywords: [brand card, brand manifest, creative generation, brand guidelines]
+---
+
+# Brand Card
+
+The **Brand Card** is a standardized manifest format that serves as the **namespace and identity** for brands in AdCP. It provides brand context, assets, and product catalogs that can be cached and reused across all media buys and creative generation requests.
+
+## Overview
+
+Brand cards solve a key problem: how to efficiently provide brand context without requiring complex authorization flows or repeated data entry. By making the brand card the central identifier for all advertising activity, AdCP enables:
+
+- **Natural grouping**: All media buys and creatives for a brand reference the same card
+- **Consistent identity**: Brand guidelines automatically travel with every request
+- **Better caching**: Fetch once, use everywhere
+- **Simplified queries**: "Show me all campaigns for this brand"
+- **Asset discovery**: Creative requests automatically access brand assets
+
+### Key Benefits
+
+- **Namespace**: Brand card serves as the primary identifier for all advertising activity
+- **Minimal Friction**: Start with just a name or URL, expand as needed
+- **Cacheable**: Same brand card reused across all requests
+- **Standardized**: Consistent format across all AdCP implementations
+- **Flexible**: Supports SMB to enterprise use cases
+- **AI-Optimized**: Structured for easy ingestion by creative agents
+
+## Use Cases
+
+### SMB / Ad Hoc Creative Generation
+
+For small businesses or one-off campaigns, a minimal brand card provides enough context:
+
+```json
+{
+  "url": "https://bobsfunburgers.com"
+}
+```
+
+Creative agents can infer brand information from the URL, pulling logos, colors, and style from the website.
+
+### Enterprise / Established Brand
+
+For established brands with defined guidelines, the brand card provides comprehensive context:
+
+```json
+{
+  "url": "https://acmecorp.com",
+  "name": "ACME Corporation",
+  "logos": [
+    {
+      "url": "https://cdn.acmecorp.com/logo-square-dark.png",
+      "tags": ["dark", "square"],
+      "width": 512,
+      "height": 512
+    },
+    {
+      "url": "https://cdn.acmecorp.com/logo-horizontal-light.png",
+      "tags": ["light", "horizontal"],
+      "width": 1200,
+      "height": 400
+    }
+  ],
+  "colors": {
+    "primary": "#FF6B35",
+    "secondary": "#004E89",
+    "accent": "#F7931E",
+    "background": "#FFFFFF",
+    "text": "#1A1A1A"
+  },
+  "fonts": {
+    "primary": "Helvetica Neue",
+    "secondary": "Georgia"
+  },
+  "tone": "professional and trustworthy",
+  "tagline": "Innovation You Can Trust",
+  "product_feed": "https://acmecorp.com/products.rss",
+  "industry": "technology",
+  "target_audience": "business decision-makers aged 35-55"
+}
+```
+
+### Multi-SKU Retailer
+
+Large retailers can provide product feeds and asset libraries:
+
+```json
+{
+  "url": "https://bigretail.com",
+  "name": "BigRetail",
+  "product_catalog": {
+    "feed_url": "https://bigretail.com/catalog.xml",
+    "feed_format": "google_merchant_center"
+  },
+  "disclaimers": [
+    {
+      "text": "Prices and availability subject to change",
+      "context": "pricing",
+      "required": true
+    }
+  ]
+}
+```
+
+### Brands Without URLs
+
+Some brands don't have dedicated URLs (white-label products, local businesses, B2B brands). Brand cards support name-only identification:
+
+```json
+{
+  "name": "Great Value",
+  "colors": {
+    "primary": "#0071CE",
+    "secondary": "#FFC220"
+  },
+  "tone": "affordable and trustworthy"
+}
+```
+
+**Common cases for name-only brands:**
+- White-label/store brands (e.g., "Great Value", "Kirkland")
+- Local businesses without websites
+- B2B brands without public sites
+- Sub-brands under parent company URLs
+

+
+## Integration with AdCP Tasks
+
+### create_media_buy
+
+Include brand card in media buy creation to provide context for creative generation:
+
+```json
+{
+  "buyer_ref": "campaign_2024_q1",
+  "promoted_offering": "ACME Pro Widget",
+  "brand_card": {
+    "url": "https://acmecorp.com",
+    "name": "ACME Corporation",
+    "tone": "professional and innovative"
+  },
+  "packages": [...],
+  "budget": {...}
+}
+```
+
+### build_creative
+
+Use brand card to inform creative generation:
+
+```json
+{
+  "message": "Create a native ad highlighting our new product launch",
+  "format_id": "display_native",
+  "brand_card": {
+    "url": "https://acmecorp.com",
+    "logos": [
+      {
+        "url": "https://cdn.acmecorp.com/logo-square.png",
+        "tags": ["square", "dark"]
+      }
+    ],
+    "colors": {
+      "primary": "#FF6B35",
+      "secondary": "#004E89"
+    },
+    "tone": "professional and trustworthy"
+  }
+}
+```
+
+## Best Practices
+
+### 1. Start Simple, Expand as Needed
+
+Begin with just a URL. Add more fields only when the URL-based inference isn't sufficient:
+
+```json
+// ✅ Good starting point
+{
+  "url": "https://mybrand.com"
+}
+
+// ✅ Add details when needed
+{
+  "url": "https://mybrand.com",
+  "logos": [...],
+  "colors": {...}
+}
+```
+
+### 2. Use Semantic Tags for Logos
+
+Tags help creative agents select appropriate logo variants:
+
+```json
+{
+  "logos": [
+    {"url": "...", "tags": ["dark", "square"]},      // For light backgrounds
+    {"url": "...", "tags": ["light", "square"]},     // For dark backgrounds
+    {"url": "...", "tags": ["dark", "horizontal"]},  // Wide layouts
+    {"url": "...", "tags": ["icon"]}                 // Small placements
+  ]
+}
+```
+
+### 3. Cache and Reuse Brand Cards
+
+Brand cards are designed to be cached:
+
+```javascript
+// Cache brand card once
+const brandCard = {
+  url: "https://acmecorp.com",
+  colors: {...},
+  logos: [...]
+};
+
+// Reuse across requests
+await createMediaBuy({ brand_card: brandCard, ... });
+await buildCreative({ brand_card: brandCard, ... });
+await buildCreative({ brand_card: brandCard, ... }); // Same card, different creative
+```
+
+### 4. Product Feeds for Multi-SKU
+
+Large retailers should provide product feeds:
+
+```json
+{
+  "url": "https://retailer.com",
+  "product_feed": "https://retailer.com/products.json"
+}
+```
+
+**Supported Feed Formats**: RSS, JSON Feed, Product CSV
+
+### 5. Asset Libraries for Enterprise
+
+Enterprise brands with large asset libraries should provide API endpoints:
+
+```json
+{
+  "asset_library": {
+    "images": "https://assets.brand.com/api/images",
+    "videos": "https://assets.brand.com/api/videos"
+  }
+}
+```
+
+## Evolution and Versioning
+
+Brand cards are versioned using the `metadata.version` field:
+
+```json
+{
+  "url": "https://brand.com",
+  "metadata": {
+    "version": "2.1",
+    "updated_date": "2024-03-15T10:00:00Z"
+  }
+}
+```
+
+Version updates:
+- **Patch** (2.0.1): Fix typos, update contact info
+- **Minor** (2.1.0): Add new assets, update colors
+- **Major** (3.0.0): Complete rebrand, new identity
+
+## Migration from brand_guidelines
+
+For implementations using the legacy `brand_guidelines` field in `build_creative`:
+
+**Before (Legacy)**:
+```json
+{
+  "brand_guidelines": {
+    "colors": ["#FF6B35", "#004E89"],
+    "fonts": ["Helvetica Neue"],
+    "tone": "professional"
+  }
+}
+```
+
+**After (Brand Card)**:
+```json
+{
+  "brand_card": {
+    "url": "https://brand.com",
+    "colors": {
+      "primary": "#FF6B35",
+      "secondary": "#004E89"
+    },
+    "fonts": {
+      "primary": "Helvetica Neue"
+    },
+    "tone": "professional"
+  }
+}
+```
