Testing Strategies

But…What should we test?

“When should you use Multivariate testing, and when is A/B/n testing best?”

  • Test dramatic design changes
  • Install advanced analytics to evaluate for each variation (i.e., mouse tracking info, phone calls, etc.)
  • Typically bigger gains are achieved because bigger changes are often tested.

Statistics for A/B testing

Non-binomial data

  • Average Revenue per user
  • Average Order value
  • Average Orders per user
  • Average Session duration
  • Average Pages per session
  • Requires extra effort
  • Can be more difficult or even impossible to extract data necessary for estimating the standard deviation from popular software such as Google Analytics
  • Increased sample size requirements due to increased variance
  • Often these metrics are closest to the business’s bottom line (e.g. ARPU*) and are more actionable.
  • May obscure underlying changes (ARPU* is up BUT is it due to an increase in conversion rate, OR average order value, OR both?).
