YouTube Own Channel Analyzer

Analyze your YouTube channel's performance using the YouTube Data API v3.

Setup

1. API Key: Get from Google Cloud Console - enable YouTube Data API v3
2. Channel ID: Accept channel ID (UC...), @handle, or full URL

API Endpoints

BASE_URL = https://www.googleapis.com/youtube/v3

# Channel details
GET /channels?part=snippet,statistics,contentDetails,brandingSettings&id={channelId}&key={API_KEY}

# Channel videos (paginated)
GET /search?part=snippet&channelId={channelId}&order=date&type=video&maxResults=50&key={API_KEY}

# Video details (batch up to 50 IDs)
GET /videos?part=snippet,statistics,contentDetails&id={videoIds}&key={API_KEY}

Analysis Workflow

1. Resolve Channel ID

@handle → Search API with handle, get channelId from result
/channel/UC... → Extract directly
/c/name or /user/name → Use forUsername parameter

2. Fetch Data

• Channel: snippet, statistics, contentDetails, brandingSettings
• Videos: Paginate through search results, then batch video details

3. Analyze

Content Types - Categorize by title/description patterns:

Type	Pattern
Tutorial	tutorial, how to, guide, learn
Review	review, unbox, first look, comparison
Vlog	vlog, day in, life, daily
Educational	explain, education, lesson
Gaming	gameplay, game, gaming, stream
Music	music, song, cover, lyrics

Duration Buckets: Short (<5min), Medium (5-15min), Long (15-30min), Very Long (30+min)

Performance Metrics:

• View-to-sub ratio: views/subscribers (benchmark: 10-20%)
• Engagement rate: (likes+comments)/views (benchmark: 1-5%)
• Like rate: likes/views (benchmark: 3-7%)
• Comment rate: comments/views (benchmark: 0.5-2%)
• Viral threshold: views > 5x subscribers
• Underperforming: views < 10% subscribers

Upload Patterns: Track day-of-week, hour-of-day, consistency (stddev of days between uploads)

const match = duration.match(/PT(?:(\d+)H)?(?:(\d+)M)?(?:(\d+)S)?/);
return (parseInt(match[1])||0)*3600 + (parseInt(match[2])||0)*60 + (parseInt(match[3])||0);
