Prerequisite Knowledge

Some experience with and understanding of performance, from any of the perspectives (e.g. devops, design, executive, marketing) mentioned in the abstract.

Description

What is performance? Depending on whom you ask, you’ll get a completely different definition.

  • If you’re a designer, performance is when your pages become usable.
  • If you’re in DevOps, performance is a set of numbers — from back-end time to DOM interactive to the load event.
  • If you’re a CEO or CRO, performance is revenue.

Not surprisingly, there’s no one-size-fits-all performance metric (though life would be simpler if there were). Different metrics will give you different critical insights into whether or not your pages are delivering the results you want — both from your end user’s perspective and ultimately from your organization’s perspective.

But regardless of your role, performance boils down to three simple questions:

  • How fast am I?
  • How fast should I be?
  • How do I get there?

In this session, we’ll walk through various metrics that answer performance questions from multiple perspectives. You’ll walk away with a better understanding of your options, as well as a clear understanding of how to choose the right metric for the right audience.

We’ll cover:

  • Types of events (browser standard, custom)
  • Timings (user, navigation, resource)
  • Behavioral events (time to scroll, time to click, time to convert)
  • Business key performance indicators (bounce rate, conversions, orders, order value, page views)
  • How to capture metrics for SPAs
  • Third-party measurement
  • Should you get your metrics from synthetic tests or RUM — or both?
  • Should you care about the metrics for some pages more than others?
  • What percentile should you care about? 50th? 95th?

We’ll also share a case study that demonstrates how to target specific metrics along specific parameters and tie it back to business outcomes — and ultimately business success!
