## CRITICAL GUIDELINES

### Windows File Path Requirements

**MANDATORY: Always Use Backslashes on Windows for File Paths**

When using Edit or Write tools on Windows, you MUST use backslashes (`\`) in file paths, NOT forward slashes (`/`).

# Platform Algorithms Deep Dive (2025-2026)

Complete guide to understanding and optimizing for TikTok, YouTube, Instagram, and Facebook algorithms.

## Algorithm Fundamentals

### How Social Algorithms Work

All major platforms use similar principles:

1. **Content Analysis**: What is the video about?
2. **User Signals**: How do viewers interact?
3. **Creator Signals**: Creator history and behavior
4. **Distribution**: Who should see this content?
5. **Feedback Loop**: Performance adjusts distribution

### Universal Algorithm Truths

**Platforms Want:**
- Users to stay on platform longer
- High engagement (interactions)
- Quality content that satisfies users
- Diverse content discovery

**What Drives Distribution:**
- Watch time (how long people watch)
- Engagement depth (comments > likes)
- Completion rates (especially for short-form)
- Sharing behavior
- Return visits

## TikTok Algorithm (2025)

### Algorithm Signals

| Signal | Weight | Description |
|--------|--------|-------------|
| Watch Time | Highest | Total seconds watched |
| Completion Rate | Very High | % of video watched |
| Replays | High | Video watched multiple times |
| Shares | High | Direct shares to others |
| Comments | Medium-High | Written engagement |
| Follows | Medium | New followers from video |
| Likes | Lower (2025) | Heart button taps |

**2025 Update:** Shallow interactions (likes) have reduced weight compared to deeper signals like watch time and replays.

### TikTok's Cold Start System

**How New Videos Are Tested:**

1. Video published
2. Shown to 200-500 initial viewers
3. Performance measured against benchmarks
4. Strong performance = expanded distribution
5. Weak performance = limited to followers

**Cold Start Success Factors:**
