## 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 |

| Subscribers | {count} | {count} | {count} |
| Total views | {count} | {count} | {count} |
| Videos | {count} | {count} | {count} |
| Avg views/video | {count} | {count} | {count} |
| Upload frequency | {X}/week | {X}/week | {X}/week |

```

## 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.
