Vendor advertising campaigns

What this feature does

Vendors spend available advertising credit on platform promotion while administrators control eligibility, lifecycle, and delivery records.

This guide describes the behavior implemented by Mallello, the people allowed to use it, and the operational checks that keep it dependable.

Detailed workflow

1. The vendor chooses an owned listing, budget, dates, and campaign placement.
2. The server validates listing status and available credit.
3. A draft or pending campaign is created and reviewed where required.
4. Approved delivery consumes budget according to platform rules.
5. The vendor and administrator inspect status and results.

Rules and permissions

• An ad never changes organic reliability metrics or listing facts.
• Spend is limited to available credit and authorized resources.
• Campaign status changes are server-enforced.
• Sponsored placement is clearly distinguishable to users.

Failure handling and edge cases

• Expired or paused campaigns stop new delivery without rewriting history.
• Listing removal pauses related advertising.
• Delivery metrics need deduplication and bot filtering before billing significance.
