Users expect a fast and optimized experience regardless of whether they’re on a mobile or desktop browser – rightfully so! However, delivering instant mobile websites requires careful engineering: you need to account for every extra network roundtrip, tune your servers, and prioritize critical assets – aka, we need to optimize the critical rendering path to deliver best visual rendering performance.

In this session we’ll take a deep dive into the technical design and optimization criteria to help us meet these goals. As a bonus, we’ll demo some existing and upcoming tools we’ve been working on at Google to automate the process.
