E-commerce search ranking must balance multiple objectives including relevance, user engagement, and platform revenue when allocating impression slots to competing listings. [^2]

Estimating expected revenue is well understood for fixed-price items but becomes challenging when inventory includes mixed listing formats such as pure auctions and hybrid 'Auction with Buy It Now' (ABIN) items. [^3]

Online A/B tests at a large e-commerce platform showed positive revenue gains and statistically significant improvements to user metrics. [^4]

The authors extend the standard Expected Cost-per-Mille (eCPM) framework by deriving a marginal eCPM (meCPM) that captures the incremental value of showing one more impression of an item whose price is still evolving. [^5]

The couple converted the bus into a mobile home over a period of less than three years using YouTube videos as instructional references. [^6]

The total renovation cost for the bus conversion was approximately $40,000. [^7]

The couple now travels through the United States and Canada in the converted bus. [^8]
