Convincing an organization that performance matters and is worth investing in is often a tough thing to sell. This was no different at Intuit, who operated many sites built in the pre “web standards” era. Then, one day, one test changed everything – an A/B comparison successfully demonstrated that faster page loads increased conversion and SEO. And the conversation quickly changed from “Not interested” to “How quickly can you make the rest of our pages faster?”
A performance team was formed, and optimization began across multiple properties in a phased approach with each release delivering incremental performance gains. As we iterated through the core performance principles, the team introduced additional techniques that led us to exceed our original performance goals. Techniques such as lazyloading, prefetching, smarter image optimization/spriting, and module rewrites enabled us to successfully shave off additional time.
This session will cover the steps that we took, lessons learned including what worked well or didn’t work well, as well as the performance improvements that were realized, and their impact on business metrics. Some of the topics include:
Jay Hung first learned about FEO (front-end optimization) in 2006 as an engineer at Yahoo!. His team was among the first to implement Steve Souders’ principles and techniques in Yahoo! products, and Jay cites Steve’s “14 rules for faster-loading web sites” as among his most valuable takeaways. Since then, Jay has gone on to optimize numerous web properties from startups to top Alexa sites, and remains hugely passionate about frontend performance.
