HKIA Content Aggregation & Competitive Intelligence System

Project Overview

Complete content aggregation system that scrapes 6 sources (WordPress, MailChimp RSS, Podcast RSS, YouTube, Instagram, HVACRSchool), converts to markdown, and runs twice daily with incremental updates. TikTok scraper disabled due to technical issues.

NEW: Phase 3 Competitive Intelligence Analysis - Advanced competitive intelligence system for tracking 5 HVACR competitors with AI-powered analysis and strategic insights.

Architecture

Core Content Aggregation

• Base Pattern: Abstract scraper class (BaseScraper) with common interface
• State Management: JSON-based incremental update tracking in data/.state/
• Parallel Processing: All 6 active sources run in parallel via ContentOrchestrator
• Output Format: hkia_[source]_[timestamp].md
• Archive System: Previous files archived to timestamped directories in data/markdown_archives/
• Media Downloads: Images/thumbnails saved to data/media/[source]/
• NAS Sync: Automated rsync to /mnt/nas/hkia/

✅ Competitive Intelligence (Phase 3) - PRODUCTION READY

• Engine: CompetitiveIntelligenceAggregator extending base IntelligenceAggregator
• AI Analysis: Claude Haiku API integration for cost-effective content analysis
• Performance: High-throughput async processing with 8-semaphore concurrency control
• Competitors Tracked: HVACR School, AC Service Tech, Refrigeration Mentor, Love2HVAC, HVAC TV
• Analytics: Market positioning, content gap analysis, engagement comparison, strategic insights
• Output: JSON reports with competitive metadata and strategic recommendations
• Status: ✅ All critical issues fixed, ready for production deployment

Key Implementation Details

Instagram Scraper (src/instagram_scraper.py)

• Uses instaloader with session persistence
• Aggressive rate limiting: 15-30 second delays, extended breaks every 5 requests
• Session file: instagram_session_hkia1.session
• Authentication: Username hkia1, password I22W5YlbRl7x

TikTok Scraper ❌ DISABLED

• Status: Disabled in orchestrator due to technical issues
• Reason: GUI requirements incompatible with automated deployment
• Code: Still available in src/tiktok_scraper_advanced.py but not active

YouTube Scraper (src/youtube_hybrid_scraper.py)

• Hybrid Approach: YouTube Data API v3 for metadata + yt-dlp for transcripts
• Channel: @HVACKnowItAll (38,400+ subscribers, 447 videos)
• API Integration: Rich metadata extraction with efficient quota usage (3 units per video)
• Authentication: Firefox cookie extraction + PO token support via YouTubePOTokenHandler
• ❌ Transcript Status: DISABLED due to YouTube platform restrictions (Aug 2025)
  • Error: "The following content is not available on this app"
  • PO Token Implementation: Complete but blocked by YouTube platform restrictions
  • 179 videos identified with captions available but currently inaccessible
  • Will automatically resume transcript extraction when platform restrictions are lifted

RSS Scrapers

• MailChimp: https://us10.campaign-archive.com/feed?u=d1a98c3e62003104038942e21&id=2205dbf985

WordPress Scraper (src/wordpress_scraper.py)

• Direct API access to hvacknowitall.com
• Fetches blog posts with full content

HVACRSchool Scraper (src/hvacrschool_scraper.py)

• Web scraping of technical articles from hvacrschool.com
• Enhanced content cleaning with duplicate removal
• Handles complex HTML structures and embedded media

Technical Stack

• Python: 3.11+ with UV package manager
• Key Dependencies:
  • instaloader (Instagram)
  • scrapling[all] (TikTok anti-bot)
  • yt-dlp (YouTube)
  • feedparser (RSS)
  • markdownify (HTML conversion)
• Testing: pytest with comprehensive mocking

    results = {}
    competitors = ['hvacrschool', 'ac_service_tech', 'refrigeration_mentor', 'love2hvac', 'hvac_tv']
    
    for competitor in competitors:
        print(f'Processing {competitor}...')
        results[competitor] = await aggregator.process_competitive_content(competitor, 'backlog')
        print(f'Processed {len(results[competitor])} items for {competitor}')
    
    print(f'Total competitive analysis completed: {sum(len(r) for r in results.values())} items')

asyncio.run(main())

Critical Notes

1. ✅ TikTok Scraper: DISABLED - No longer blocks deployment or requires GUI access
2. Instagram Rate Limiting: 100 requests/hour with exponential backoff
3. YouTube Transcript Status: DISABLED in production due to platform restrictions (Aug 2025)
   • Complete PO token implementation but blocked by YouTube platform changes
   • 179 videos identified with captions but currently inaccessible
   • Hybrid scraper architecture ready to resume when restrictions are lifted
4. State Files: Located in data/.state/ directory for incremental updates
5. Archive Management: Previous files automatically moved to timestamped archives in data/markdown_archives/[source]/
6. Media Management: Images/videos saved to data/media/[source]/ with consistent naming
7. Error Recovery: All scrapers handle rate limits and network failures gracefully
8. ✅ Production Services: Fully automated with systemd timers running twice daily
9. Package Management: Uses UV for fast Python package management (uv run, uv sync)

YouTube Transcript Status (August 2025)

Current Status: ❌ DISABLED - Transcripts extraction disabled in production

Implementation Status:

• ✅ Hybrid Scraper: Complete (src/youtube_hybrid_scraper.py)
• ✅ PO Token Handler: Full implementation with environment variable support
• ✅ Firefox Integration: Cookie extraction and profile detection working
• ✅ API Integration: YouTube Data API v3 for efficient metadata extraction
• ❌ Transcript Extraction: Disabled due to YouTube platform restrictions

Technical Details:

• 179 videos identified with captions available but currently inaccessible
• PO Token: Extracted and configured (YOUTUBE_PO_TOKEN_MWEB_GVS in .env)
• Authentication: Firefox cookies (147 extracted) + PO token support
• Platform Error: "The following content is not available on this app"

Architecture: True hybrid approach maintains efficiency:

• Metadata: YouTube Data API v3 (cheap, reliable, rich data)
• Transcripts: yt-dlp with authentication (currently blocked)
• Fallback: Gracefully continues without transcripts

Future: Will automatically resume transcript extraction when platform restrictions are resolved.
