Debugging rendering problems at scale

About this talk

To better understand a website's content search engines developed Web Rendering Services and are now able to render pages more or less like a normal user. Those Web Rendering Services are strictly connected to other phases of the crawling-indexing-ranking pipeline - if a rendering fails, it may affect all of them. In this session Giacomo will guide you through the process of understanding why rendering could be a problem also for non-Javascript pages, how to manually debug page rendering, the difference between understanding WRSs' capabilities and debugging problems on a website, and eventually how to test pages at scale.
