Ad Slot Inventory Plan

Ad Slot Inventory Plan

Reserved slot regions

• homepage hero/sidebar
• category pages
• search results
• listing detail pages
• account dashboard
• footer/header strips

Data model

• ad_slots defines placement inventory
• campaigns defines future direct-sale campaigns
• campaign_ad_slot maps campaigns to slots

Why reserve from day one

• avoids hardcoded ad fragments
• keeps monetization compatible with self-serve or operator-managed campaigns later
• enables future click/impression logging without redesigning templates

Tracking expansion

The next phase should add tables for:

• impressions
• clicks
• creatives
• advertiser accounts
