In this article, I review six metrics commonly used to measure UX: conversion rate (CR), average order value (AOV), task success rate, time on task, Net Promoter Score® (NPS), and the System Usability Scale (SUS). CR, AOV, and NPS do not fulfil the definition of a UX metric while task success rate, time on task, and SUS do. Still, none of the metrics (alone) is suitable to reliably measure the UX of a digital product.
An effective personalization strategy should be treated as a design problem with a structured framework of ideation, implementation, and evaluation. Co-creation workshops are used to brainstorm audiences and personalized content based on credible hypotheses, which are then implemented and continuously monitored to assess the performance of the personalization strategy and individual campaigns. A good strategy focuses on UX while helping with achieving business goals.

Usability testing is often perceived as cumbersome and time-consuming and therefore not thoroughly applied. This was one of the key observations leading to the topic of my PhD thesis. Particularly conducting tests with actual users is often omitted, which results in the release of suboptimal products and websites. In my thesis, I tackle this problem through more… Continue reading The U Score: Redesigning Usability Testing
As one of the building blocks of my PhD thesis, I have developed a novel instrument for measuring the usability of web interfaces, which is simply called Inuit—the Interface Usability Instrument1. This was necessary because a usability instrument that is suited for the automatic methods for Search Interaction Optimization I have developed in my PhD… Continue reading INUIT: The Interface Usability Instrument
