Implementation Type: Multi-Platform Analytics Integration with Age-Based Sync

Overview

The Analytics Foundation provides a unified system for tracking, syncing, and analyzing content performance across multiple platforms (social media, blogs, etc.). The implementation includes Google Analytics 4 integration for blog content and a extensible architecture for adding more analytics providers.

Core Components

1. Database Schema (Prisma)

All analytics-related models are defined in the Prisma schema:

• AnalyticsConnection: Stores encrypted credentials for analytics platforms (GA4, etc.)
• ContentMetrics: Unified metrics storage for all content types
• MetricsSnapshot: Daily snapshots for trend analysis

Key Features:

• Multi-tenant support via companyId
• Encrypted credential storage using AES-256
• Composite unique constraints for data integrity
• Support for multiple content types: BLOG_POST, SOCIAL_POST, VIDEO_SCRIPT

2. Google Analytics 4 (GA4) Adapter

File: apps/backend/src/services/analytics/ga4.adapter.ts

Capabilities:

• Single URL metrics fetching
• Batch URL metrics fetching (efficient for multiple URLs)
• Connection testing
• Multiple date range support (7 days, 30 days, all-time)

Metrics Tracked:

• Page views (7d, 30d, all-time)
• Average time on page
• Bounce rate
• Engaged sessions

Architecture: Singleton pattern with credential-based client initialization

3. Analytics Sync Service

File: apps/backend/src/services/analytics/analyticsSync.service.ts

Age-Based Sync Frequency:

Content Age	Sync Interval	Rationale
< 24 hours	Every 2 hours	Recent content changes rapidly
1-7 days	Every 6 hours	Active content still volatile
7-30 days	Daily	Slower growth, less frequent checks
> 30 days	Weekly	Archive content, minimal changes

Key Features:

• Smart content filtering (queries only what needs syncing)
• Platform grouping for batch processing
• Daily snapshot creation for historical trends
• Engagement rate calculation
• Error tracking and recovery

Methods:

• scheduleSync(): Creates Cloud Tasks for sync jobs
• getContentNeedingSync(): Complex query logic for age-based filtering
• processSyncJob(): Processes sync tasks from Cloud Tasks
• syncMetric(): Individual metric sync with GA4 adapter
• createSnapshot(): Upsert daily snapshots

4. Multi-Tenant Social Analytics

File: apps/backend/src/services/analytics/analyticsSync.ts

Provides social media analytics sync:

• Platform-specific analytics fetching (LinkedIn, Twitter/X, Facebook, Instagram, Pinterest, TikTok)
• Normalized metrics structure
• Tenant-scoped queries using getTenantPrisma()
• Stores metrics in ContentMetrics table

Integration Points:

• getLinkedInAnalytics() from linkedin.service.ts
• getTwitterAnalytics() from twitter.service.ts
• getFacebookAnalytics(), getInstagramAnalytics() from facebook.service.ts
• getPinterestAnalytics(), getTikTokAnalytics() from other.service.ts

5. Analytics API Routes

File: apps/backend/src/routes/analytics.ts

Endpoints:

GA4 Connections

• POST /api/analytics/connections/ga4 - Create GA4 connection
• GET /api/analytics/connections - List all connections
• GET /api/analytics/connections/:id - Get connection details
• PUT /api/analytics/connections/:id - Update connection
• DELETE /api/analytics/connections/:id - Delete connection
• POST /api/analytics/connections/:id/test - Test connection

Metrics Retrieval

• POST /api/analytics/metrics/fetch - Fetch metrics for specific URLs
• GET /api/analytics/metrics - Query stored metrics
• GET /api/analytics/aggregate - Aggregate metrics across content

Top Performers

• GET /api/analytics/top-performing - Get top-performing content

Security:

• All routes protected by JWT authentication (verifyJwt middleware)
• Credentials encrypted before storage using encrypt() from encryption.ts
• Tenant isolation enforced via getTenantPrisma(companyId)

6. Cloud Tasks Integration

Webhook Handler: apps/backend/src/routes/jobs.ts

Endpoint: POST /api/jobs/sync-analytics

Features:

• Webhook secret authentication
• Supports company-specific sync or all-company sync
• Imports analytics sync worker dynamically
• Error handling with 500 status for Cloud Tasks retry

Payload Schema:

{
  companyId?: string, // Optional: sync specific tenant
  idempotencyKey: string
}

7. Analytics Sync Worker

File: apps/backend/src/jobs/analyticsSyncWorker.ts

Purpose: Entry point for scheduled analytics sync jobs

Features:

• Can be run directly via Node.js (node dist/jobs/analyticsSyncWorker.js)
• Iterates over all companies and syncs their analytics
• ESM-compatible module detection using import.meta.url
• Integrates with Cloud Scheduler for periodic execution

Data Flow

1. Blog Analytics Sync Flow

Cloud Scheduler (Trigger)
    ↓
POST /api/jobs/sync-analytics (Webhook)
    ↓
runAnalyticsSync() or syncAnalyticsForTenant(companyId)
    ↓
AnalyticsSyncService.scheduleSync()
    ↓
getContentNeedingSync() (Age-based filtering)
    ↓
Group by platform → Create Cloud Tasks
    ↓
Cloud Tasks calls processSyncJob()
    ↓
For each metric:
    ├─ Get AnalyticsConnection
    ├─ Fetch fresh metrics from GA4
    ├─ Calculate engagement rate
    ├─ Update ContentMetrics record
    └─ Create daily MetricsSnapshot

2. Social Media Analytics Sync Flow

Webhook Trigger or Scheduled Job
    ↓
syncAnalyticsForTenant(companyId)
    ↓
Query published Posts with remoteId
    ↓
For each post:
    ├─ Determine platform
    ├─ Call platform-specific analytics API
    ├─ Normalize metrics
    └─ Upsert into ContentMetrics

Configuration

Environment Variables

# Google Cloud (for Cloud Tasks)
GCP_PROJECT_ID=tendsocial
GCP_TASKS_QUEUE=default
GCP_LOCATION=us-central1

# Webhook Security
WEBHOOK_SECRET=your-webhook-secret-here

# Encryption (already configured)
ENCRYPTION_KEY=your-32-byte-hex-key

Cloud Scheduler Setup

Create a Cloud Scheduler job to trigger analytics sync:

gcloud scheduler jobs create http analytics-sync \
  --schedule="0 */2 * * *" \
  --uri="https://your-api-domain.com/api/jobs/sync-analytics" \
  --http-method=POST \
  --headers="x-webhook-secret=YOUR_WEBHOOK_SECRET" \
  --message-body='{"idempotencyKey":"scheduled-sync"}' \
  --location=us-central1

GA4 Service Account Setup

Steps to Set Up GA4 Integration

1. Create Service Account:

   • Go to Google Cloud Console
   • Navigate to IAM & Admin > Service Accounts
   • Create new service account with Viewer role

2. Generate JSON Key:

   • Click on service account
   • Go to Keys tab
   • Add Key > Create new key > JSON
   • Download the JSON file

3. Grant GA4 Access:

   • Go to Google Analytics 4 property
   • Admin > Property Access Management
   • Add service account email with Viewer role

4. Get Property ID:

   • Admin > Property Settings
   • Copy Property ID (format: 123456789)

5. Create Analytics Connection:

   POST /api/analytics/connections/ga4
   Body:
   {
     "name": "My Blog Analytics",
     "propertyId": "123456789",
     "credentials": { ... } # Paste entire JSON key content
   }

Metrics Normalization

Common Metrics Across Platforms

The system normalizes platform-specific metrics into a unified structure:

Unified Field	GA4	LinkedIn	Twitter	Facebook	Instagram
views	screenPageViews	-	impressions	impressions	impressions
impressions	-	impressions	impressions	impressions	impressions
reach	-	uniqueImpressions	-	reach	reach
likes	-	likes	likes	reactions	likes
comments	-	comments	replies	comments	comments
shares	-	shares	retweets	shares	-
clicks	-	clicks	urlClicks	linkClicks	-
engagementRate	Calculated	Calculated	Calculated	Calculated	Calculated

Engagement Rate Formula

Engagement Rate (%) = 
  (likes + comments + shares + saves) / (impressions OR reach OR views) * 100

Extension Points

Adding New Analytics Providers

1. Create Adapter (e.g., apps/backend/src/services/analytics/adobe.adapter.ts):

export class AdobeAdapter {
  async fetchMetricsForUrl(url: string, connection: AnalyticsConnection): Promise<AdobeMetrics> {
    // Implementation
  }
  
  async testConnection(connection: AnalyticsConnection): Promise<boolean> {
    // Implementation
  }
}

export const adobeAdapter = new AdobeAdapter();

2. Update Routes (analytics.ts):

fastify.post('/connections/adobe', {
  schema: { /* Adobe-specific schema */ },
  handler: async (request, reply) => {
    // Create Adobe connection
  }
});

3. Update Sync Service (analyticsSync.service.ts):

private async syncMetric(metric: any): Promise<void> {
  // ...existing code...
  
  if (connection.provider === 'adobe') {
    freshMetrics = await adobeAdapter.fetchMetricsForUrl(url, connection);
  }
}

Adding New Content Types

1. Update Prisma schema:

enum ContentType {
  BLOG_POST
  SOCIAL_POST
  VIDEO_SCRIPT
  PODCAST_EPISODE  // New!
}

2. Update sync config in analyticsSync.service.ts:

interface SyncConfig {
  contentType?: 'BLOG_POST' | 'SOCIAL_POST' | 'VIDEO_SCRIPT' | 'PODCAST_EPISODE';
  // ...
}

3. Add content-specific queries as needed

Testing

Manual Testing Checklist

• [ ] Create GA4 connection
• [ ] Test GA4 connection
• [ ] Fetch metrics for a single URL
• [ ] Fetch metrics for multiple URLs (batch)
• [ ] Trigger manual sync via API
• [ ] Verify metrics stored in database
• [ ] Verify daily snapshots created
• [ ] Check engagement rate calculation
• [ ] Test age-based sync frequency logic
• [ ] Verify webhook authentication
• [ ] Test tenant isolation

Example Test Requests

Create GA4 Connection:

POST /api/analytics/connections/ga4
Authorization: Bearer YOUR_JWT_TOKEN
Content-Type: application/json

{
  "name": "Production Blog",
  "propertyId": "123456789",
  "credentials": {
    "type": "service_account",
    "project_id": "your-project",
    "private_key": "-----BEGIN PRIVATE KEY-----\n...",
    "client_email": "analytics@your-project.iam.gserviceaccount.com",
    ...
  }
}

Fetch Metrics:

POST /api/analytics/metrics/fetch
Authorization: Bearer YOUR_JWT_TOKEN
Content-Type: application/json

{
  "connectionId": "connection-uuid",
  "urls": [
    "https://example.com/blog/post-1",
    "https://example.com/blog/post-2"
  ]
}

Get Aggregated Metrics:

GET /api/analytics/aggregate?startDate=2025-01-01&endDate=2025-01-31&contentType=BLOG_POST
Authorization: Bearer YOUR_JWT_TOKEN

Known Limitations

1. GA4 API Quotas: Google Analytics 4 has API quota limits. For high-volume use, implement request throttling.

2. Snapshot Storage: Daily snapshots accumulate over time. Consider implementing a retention policy (e.g., keep snapshots for 1 year).

3. Batch Size: getContentNeedingSync() limits to 1000 items. For larger datasets, implement pagination.

4. Social Platform Rate Limits: Each social platform has different rate limits. The current implementation doesn't include platform-specific throttling.

Performance Considerations

Optimizations Implemented

1. Age-Based Sync Frequency: Reduces API calls by syncing older content less frequently
2. Batch Processing: GA4 adapter supports batch URL fetching
3. Platform Grouping: Groups content by platform to minimize API connections
4. Snapshot Upserts: Updates existing snapshots instead of always creating new ones
5. Parallel Requests: GA4 adapter fetches multiple date ranges in parallel

Future Optimizations

• Implement Redis caching for frequently accessed metrics
• Add background job queue for large sync operations
• Implement progressive sync (high-priority content first)
• Add metric delta storage (only store changes)

Troubleshooting

Common Issues

Issue: GA4 connection test fails
Solution:

• Verify service account has Viewer access to GA4 property
• Check property ID is correct
• Ensure credentials JSON is complete and valid

Issue: Metrics not syncing
Solution:

• Check Cloud Tasks are being created (view logs)
• Verify webhook secret matches between Cloud Scheduler and API
• Check ContentMetrics.lastSyncedAt to see if records are being updated
• Review error logs for API failures

Issue: Engagement rate is null
Solution:

• Engagement rate requires impressions, reach, or views to be > 0
• Check if platform is returning these metrics
