# extension-publishing

## Workflow

```
prepare → package → submit → review → publish
```

1. **Prepare**: assets, privacy policy, permission justifications, manifest
2. **Package**: `zip` source (exclude dev files), validate manifest
3. **Submit**: Chrome Web Store Developer Dashboard
4. **Review**: 1–3 days typical; up to 7 days for new publishers
5. **Publish**: auto or manual rollout

## Top 10 Rejection Reasons

1. Single purpose violation — does too many unrelated things
2. Excessive/unnecessary permissions
3. Missing privacy policy (required when user data collected)
4. Missing permission justification in submission form
5. Description doesn't match functionality
6. Keyword spam in title/description
7. Remote code execution (`eval`, external scripts)
8. Improper user data handling or disclosure
9. Extension non-functional or crashes
10. Broken features / inaccessible links

## Listing Optimization Essentials

- **Title**: `<Action verb> + <Benefit>`, max 45 chars, no keyword stuffing
- **Description first 150 chars**: shown in search — make them count
- **Structure**: problem → solution → key benefits → CTA
- **Screenshots**: annotate features, show real UI, 1280×800
- **Category**: choose most specific fit
