Help me build a simple link generator for content creator tracking:

BACKEND LINK GENERATOR:
Create a simple form in my existing backend system that generates clean trackable links:

INPUT FIELDS:
- Creator/source name: ie [growth-newsletter] or [entrepreneur-podcast]
- Content type: podcast, newsletter, blog, interview
- Optional: specific episode/article name

AUTO-GENERATE CLEAN LINK:
- Simple format: yoursite.com/?ref=[source-name]
- Example: yoursite.com/?ref=growth-newsletter
- Example: yoursite.com/?ref=entrepreneur-podcast

BACKEND TRACKING:
When someone visits the link, automatically:
- Capture the "ref" parameter value
- Log it in existing traffic_sources table
- Track all signups/purchases back to that creator
- Show performance in main analytics dashboard

CREATOR EXPERIENCE:
- Give creators a clean, professional link to share
- Easy to remember: yoursite.com/?ref=their-name
- No ugly UTM parameters or complex tracking codes
- Looks trustworthy in show notes, articles, emails

INTEGRATION:
- Works with existing analytics foundation
- Creator performance shows alongside referrals and other sources
- Compare ROI across all growth methods in unified dashboard

Keep it simple - just generates clean links that track properly in the backend.
