## 2. Technical Architecture & Data Ingestion

Rank Kiwi operates entirely as a local Chrome Extension content script injected into active Instagram and YouTube tabs.

### Instagram Reels Intelligence Pipeline
- **Target Surfaces**:
  - Creator profile grid and dedicated Reels tab: `https://www.instagram.com/{username}/reels/`
  - Explore feed direct video discovery: `https://www.instagram.com/explore/`
- **Data Attributes Extracted**:
  - Reel shortcode identifier (`/reel/{shortcode}/`)
  - Video MP4 source URL
  - Raw view count / play count
  - Like count and comment count
  - Full caption copy and hashtags
  - Publication timestamp
  - Creator handle and profile display name
- **Strict Video Isolation (Carousel Rejection)**:
  - Rank Kiwi specifically filters out static images and photo carousels from the Reels dataset. Including zero-play static carousels would artificially depress the creator's video median, distorting true outlier multipliers.
- **In-Modal Video Player & Media Download**:
  - Responsive 9:16 HTML5 video modal with timeline scrubber, duration countdown, and dynamic audio visualizer.
  - Single-click MP4 downloading: generates clean standardized filenames (`rankkiwi_{creator}_{shortcode}.mp4`).
  - Batch select & download: allows creators to download multiple outlier MP4s simultaneously for offline hook and format analysis.

### YouTube Videos & Shorts Intelligence Pipeline
- **Target Surfaces**:
  - Channel uploads catalog: `https://www.youtube.com/@{channel}/videos`
  - YouTube Shorts catalog: `https://www.youtube.com/@{channel}/shorts`
- **Creator Anti-Leakage Validation**:
  - Algorithmic DOM boundary verification ensures that recommended videos, sidebar suggestions, or multi-creator carousel elements from external channels are never injected into the current creator's benchmark dataset.
- **Live Stats Enrichment Queue**:
  - Uses a bounded, rate-controlled worker queue to fetch exact real-time view counts, likes, and comment counts for visible videos.
- **Thumbnail Extraction**:
  - High-resolution thumbnail downloading directly from the results grid (extracts 1080p `maxresdefault.jpg` with graceful fallback to `hqdefault.jpg`).
- **Strict YouTube Platform Policy Compliance**:
  - Rank Kiwi strictly prohibits and prevents downloading YouTube video or audio streams, fully complying with YouTube Terms of Service and developer guidelines. Only public metadata and thumbnails are processed.

### Client-Side Multi-Format Export Engine
- **Excel (.xlsx)**:
  - Generates binary Open Packaging Conventions `.xlsx` workbooks directly inside the browser memory without external NPM dependencies or remote API calls. Uses a custom, lightweight PKZIP Store archive engine with proper sheet XML, styles, and data types.
- **CSV**:
  - Standard RFC 4180 CSV export with UTF-8 Byte Order Mark (BOM) for seamless character decoding in Microsoft Excel and Numbers.
- **JSON**:
  - Full structured JSON array containing all normalized metrics, timestamps, URLs, captions, and outlier multipliers.
- **Clipboard (Dual-Channel TSV & HTML Table)**:
  - Copies both plain text tab-separated values (TSV) and styled HTML tables to the system clipboard simultaneously. When pasted into Google Sheets, Excel, or Notion, columns format automatically with styled numbers and clickable links.

## 3. The Outlier Score Metric: Mathematics & Benchmarks

Traditional social analytics rely heavily on arithmetic mean (average). On social platforms where algorithmic distribution follows power-law distributions, arithmetic mean is fundamentally flawed: a single 10,000,000 view video will artificially inflate an average to 500,000 views, making subsequent 200,000 view videos look like failures when they are actually strong performers.

Rank Kiwi solves this by benchmarking against the **Median**:

### Mathematical Formulation
For a sampled window of $N$ posts sorted by view count $x_{(1)} \le x_{(2)} \le \dots \le x_{(N)}$:

$$\text{Median} = \begin{cases} x_{\left(\frac{N+1}{2}\right)} & \text{if } N \text{ is odd} \\ \frac{x_{\left(\frac{N}{2}\right)} + x_{\left(\frac{N}{2} + 1\right)}}{2} & \text{if } N \text{ is even} \end{cases}$$

The Outlier Score for post $i$ is calculated as:

$$\text{Outlier Score}_i = \frac{\text{Metric}_i}{\text{Median}}$$

### Multiplier Interpretation Tiers
- **`1.0×` (Typical)**: The post performed exactly at the creator's median expectation.
- **`1.5× – 1.9×` (Above Average)**: Meaningful audience engagement above typical levels.
- **`2.0× – 3.5×` (Strong Performer)**: Strong resonance. Content beat at least 80% of normal uploads.
- **`4.0× – 9.9×` (Viral Outlier)**: Massive algorithmic breakout. The hook, topic, or format broke out of the creator's core audience into broad recommendation feeds.
- **`10.0×+` (Megaviral Anomaly)**: Statistical extreme. Typically driven by external distribution cascades or cultural moments.
- **Hidden Metrics (`null` / `—`)**:
  - When creators hide public view or like counts, Rank Kiwi normalizes the metric to `null`, renders an em-dash (`—`), and automatically sorts these posts to the bottom of the grid to prevent distorting calculations.

## 4. Empirical Research Studies & Open Data

Rank Kiwi publishes quantitative creator economy studies with open data transparency standards.

### Study 1: "One Video Doesn't Tell You How Good a Creator Is"
- **URL**: https://rankkiwi.com/research/one-video-is-not-a-channel/
- **Dataset**: vidIQ empirical study analyzing **448,000 YouTube channels** across 10 subscriber tiers.
- **Key Finding**: Across all 448k channels analyzed, the median best-of-first-10 uploads earned **10.82× more views** than the creator's first upload. Judging creator trajectory or channel viability on an initial sample is statistically invalid.
- **Summary Cohort Table**:
  | Subscriber Cohort | Channel Count | Median 1st Video Views | Median Best-of-10 Views | Multiplier Spread |
  | :--- | :--- | :--- | :--- | :--- |
  | 1k – 10k | 214,000 | 48 | 512 | 10.67× |
  | 10k – 50k | 128,000 | 184 | 1,980 | 10.76× |
  | 50k – 100k | 42,000 | 490 | 5,340 | 10.90× |
  | 100k – 250k | 31,000 | 1,120 | 12,200 | 10.89× |
  | 250k – 500k | 16,000 | 2,450 | 26,800 | 10.94× |
  | 500k – 1M | 8,500 | 5,100 | 55,600 | 10.90× |
  | 1M – 2.5M | 5,100 | 11,200 | 121,000 | 10.80× |
  | 2.5M – 5M | 2,100 | 24,000 | 258,000 | 10.75× |
  | 5M – 10M | 950 | 54,000 | 578,000 | 10.70× |
  | 10M+ | 450 | 142,000 | 1,510,000 | 10.63× |
  | **Overall Aggregate** | **448,000** | **—** | **—** | **10.82×** |
- **Open Data CSV Download**: https://rankkiwi.com/research/datasets/vidiq-448k-channel-study-summary.csv

### Study 2: YouTube Upload Cadence vs Channel Growth
- **URL**: https://rankkiwi.com/research/youtube-upload-frequency/
- **Dataset**: Analysis of **10.2 million YouTube channels** investigating upload frequency vs median subscriber growth rates.
- **Key Finding**: Channels publishing 2–3 high-effort videos per week achieve 88% of the median growth rate of daily uploaders while maintaining significantly higher retention and Outlier Scores. Daily uploading often degrades median benchmark views.

### Study 3: YouTube Channel Size Rarity Census
- **URL**: https://rankkiwi.com/research/youtube-channel-size/
- **Dataset**: Census of **61.2 million active YouTube channels**.
- **Key Finding**: Only **0.13% of all channels** ever reach 1,000,000 subscribers, and only **4.8%** reach 10,000 subscribers. Demonstrates why competitor benchmarking must occur relative to channel scale.

### Study 4: Instagram Reels vs Carousels Benchmark
- **URL**: https://rankkiwi.com/research/instagram-reels-vs-carousels/
- **Dataset**: Buffer study of **4 million+ Instagram posts**.
- **Key Finding**: Reels produce 2.1× higher non-follower discovery reach, while carousels produce 1.8× higher comment and save rates. Rank Kiwi isolates Reels to accurately quantify reach outliers.

### Study 5: Instagram Views by Account Size
- **URL**: https://rankkiwi.com/research/instagram-views-by-account-size/
- **Dataset**: Socialinsider benchmark across 5 follower tiers (<10k, 10–50k, 50–100k, 100–500k, 500k+).
- **Key Finding**: Smaller creators (<50k followers) exhibit 3.4× higher outlier volatility than mega-accounts (500k+), making relative Outlier Scores crucial for micro-creator discovery.
