The problem
How do we increase ad revenue while reducing tech debt and protecting UX?
1. Ad Placement Issues: Several ad placements weren't loading correctly due to an overlay prompting users to subscribe for an ad-free experience. This negatively impacted both user experience and revenue generation.

2. Auction Inefficiencies: The platform utilized a first-price auction system, where the winning advertiser pays their bid amount. A more efficient approach would be a second-price or Vickery auction, where the winning advertiser pays just above the second-highest bid, encouraging honest and transparent bidding.
3. Ad Server & Ad Format Optimizations: While rectifying the ad server to ensure proper ad display was a positive step towards revenue enhancement, there was also a clear customer demand for diverse ad formats. To address this, I initiated A/B testing for new formats to ensure that any changes would not detract from the user experience.
