This document discusses AdPushup, a solution that helps web publishers optimize ad revenue. It uses A/B testing of different ad placements, sizes, and types to improve click-through rates and revenue per thousand impressions. Since display advertising is growing significantly, AdPushup's approach can help publishers maximize profits from their ad spaces. A case study showed it increasing one publisher's revenue per thousand impressions from $3.82 to $12.10. AdPushup plans to monetize further as it adds more publisher clients and inventory.
