Driving user growth with performance improvements

Driving user growth with performance improvements

摘要

In early 2015 Pinterest engineers ran an experiment that improved mobile web home landing page performance by 60 percent and mobile signup conversion rate by 40 percent. However, the experiment was a hacky solution that used a lot of shortcuts like serving pre-rendered HTML pages without using any internal template rendering engines or common resources (JS, CSS). To productionize learnings from this experiment, the entire front end engine, all page templates and common elements had to be rewritten. It was a huge effort, and to achieve it, we needed to start from building robust metrics to track our progress for all parts of the serving system. In this post, we’ll cover how we improved performance on Pinterest pages, and how it led to the biggest increase in user acquisition of 2016.
