Real user monitoring is one of the best ways of learning “the truth” about what visitors experience on your web site, but it comes at a cost. The real world is messy and noisy making it hard to know exactly what’s going on. Filtering your data, splitting it along multiple dimensions, and determining what to discard are important second steps on the path to insightful RUM analysis, and in this session, we’ll go into some of the details.

We’ll talk about:

  • Collecting your own data and how to tell if you have enough.
  • Filtering out fake data and noise.
  • What dimensions to analyze
  • Special considerations for mobile visitors

Finally, we’ll go into some of the insights we’ve picked up through analyzing RUM data from around the world over the last 9 months.
