Unknown per-ad revenue for PromoPlot placements

Determine the actual revenue generated per advertisement inserted via the PromoPlot Python package in peer-reviewed journal figures, replacing the current estimate derived by scaling New York Times advertising rates with contract-based, empirically grounded figures from advertising partners.

Background

The paper models potential revenue from inserting advertisements into the unused upper half of corner plots, using New York Times ad rates scaled by readership and page area as a proxy. However, the authors do not have finalized agreements with advertisers and therefore cannot provide validated per-ad revenue figures.

Establishing realistic per-ad revenue is necessary to assess whether PromoPlot can offset open-access publication fees and to calibrate recommendations on the number of corner plots required per paper.
