We're an industry of ideas—ideas that feed our interests and enhance our work. Each perspective is a potential catalyst for growth. In this excerpt from Demystifying Public Speaking, Lara Hogan tells us why and how to give public speaking a try.
The technical aspects of performance optimization are indisputably important. But the social work—convincing peers, managers, and clients that performance optimization merits their attention—often gets short shrift. Lara Hogan shows us how we can go beyond charts, graphs, and numbers to show performance rather than merely tell it—and effect a genuine culture shift in the process.
Adding half a second to a search results page can decrease traffic and ad revenues by 20 percent, says a Google study. For every additional 100 milliseconds of load time, sales decrease by 1 percent, Amazon finds. Users expect pages to load in two seconds—and after three seconds, up to 40 percent will simply leave. The message is clear: we must make performance optimization a fundamental part of how we design, build, and test every site we create—for every device. Design for performance; measure the results.
Data is an invaluable tool for web designers who are making decisions about the user experience. A/B tests, or split tests, are one of the easiest ways to measure the effect of different design, content, or functionality, helping you create high-performing user experience elements that you can implement across your site. But it’s important to make sure you reach statistically significant results and avoid red herrings. Lara Swanson shows us how to do that.
