Web performance and ad performance go hand in hand and often, ads impact web performance far more than we realize. Engineers spend months/years of effort on optimizing performance, but ads are usually of developer control and visibility. This presentation talks about the display ad ecosystem, how display ads are integrated into Web2.0 applications, and their impact on different aspects of latency and user experience. It details the “ad journey” of Yahoo! Mail and how we have applied those learnings to improve the perceived ad experience in our latest release. Methodologies on ad troubleshooting, instrumentation, and monitoring are discussed. In particular, Web 2.0 techniques on how to holistically improve user experience and most importantly, perceived performance, due to ads, are shared.
