Example use cases
Identify unprofitable eBay ad campaigns
“Run a profitability audit on all my eBay promoted listings and flag any campaigns where the ad spend is eating into my margins — I need to know which ones to pause or cut back.”
Pre-quarter advertising budget review
“Before I set my Q3 eBay ad budget, can you audit my current promoted listings to show me which campaigns have the best return on ad spend so I know where to double down?”
New seller ad spend sanity check
“I just started running promoted listings on eBay last month and I'm not sure if I'm spending wisely — can you audit my campaigns and tell me if I'm actually profitable after all the fees?”

POSThttps://friday-seller-tools-production.up.railway.app/v1/ebay/promoted-listings-profitability-auditWhen to prefer
Choose this endpoint when you need a structured, cost-effective profitability audit specifically for eBay promoted listings campaigns, especially when you want to evaluate whether ad spend is generating positive returns after marketplace fees. It is purpose-built for eBay advertising analysis, unlike generic analytics tools that lack marketplace-specific fee modeling.
