Scoring Algorithm
Posts are scored for CTA relevance based on:
- Keyword density - How many relevant keywords appear
- Content length - Longer posts = better candidates
- Topic match - Title and content topic alignment
- Existing CTAs - Skip posts that already have CTAs
Scores range from 0-10. Default threshold: 5.0
Safety Features
- Dry-run mode by default
- Backup creation before any modifications
- Duplicate detection - Won't inject if CTA already exists
- Rollback capability - Restore from backups
- Preview diffs - See exactly what will change
