Analysis Process

Step 1: Channel Overview

Pull channel data and compute:

| Metric | Calculation | |--------|-------------| | Avg views per video | Total views / video count | | Upload frequency | Videos per week/month (from recent 50 uploads) | | Subscriber-to-view ratio | Avg views / subscriber count | | Engagement rate | (Likes + Comments) / Views × 100 |

Step 2: Top Performing Content

List the last 50 videos and sort by:

1. View count (absolute performance)
2. Views per day since publish (velocity)
3. Engagement rate (likes + comments / views)
4. Like-to-view ratio

Identify patterns in top performers:

• Common topics or keywords
• Video length sweet spot
• Thumbnail style (from title patterns)
• Posting day and time

Step 3: Content Gaps

Search for the channel's core keywords and compare:

• What top-ranking videos cover vs. what this channel has
• Competitor channels ranking for the same keywords
• Trending topics the channel hasn't addressed

Step 4: YouTube SEO Analysis

For each video analyzed, check:

| Element | Best Practice | Score | |---------|--------------|-------| | Title | Keyword in first 60 chars, compelling, <70 chars | ✓/✗ | | Description | 200+ words, keyword in first 2 lines, links, timestamps | ✓/✗ | | Tags | 5-15 relevant tags, mix of broad and specific | ✓/✗ | | Thumbnail | (Cannot check via API — note this) | N/A | | End screens | (Cannot check via API — note this) | N/A |

Important Notes

• The YouTube Data API has a daily quota of 10,000 units. Each search costs 100 units. Each video/channel lookup costs 1-3 units. Be efficient with API calls.
• Batch video IDs in single requests (up to 50 per call) to conserve quota.
• Subscriber counts below 1,000 are hidden by YouTube. The API returns 0 in these cases.
• likeCount may not be available if the creator has hidden likes.
• API results are public data only. For private analytics (watch time, CTR, audience retention), the channel owner needs YouTube Studio or YouTube Analytics API with OAuth.
