Important UX Metrics to Measure User Experience

UX metrics are a set of quantitative data points used to measure, compare and track the user experience of a website/app over time. UX metrics measure success towards higher business goals called KPIs (Key Performance Indicators) such as revenue growth, retention, increased user numbers.

Before collecting data, it’s a good idea to outline a basic measurement strategy.

• Decide which metrics to measure.
• Establish clear timeframes in order to understand the trends that emerge. The metrics gathered in a single day may tell a much different story than those gathered over the course of a week.
• Use both qualitative and quantitative metrics

There are 2 types of UX metrics:

1. Behavioral metrics - that study how people interact with the product
2. Attitudinal metrics - explore how people feel and say about the product before, during or after using it

1. Task Success Rate - what percentage of users complete each step in a user flow.
2. Time on Task - how long a user spends completing a specific task (on first attempt and on repeat attempts)
3. Conversion Rate - % of users who took a certain action ( e.g. subscribed or bought something)
4. Retention Rate - what percentage of users continue using your product long-term.
5. Search vs Navigation Pattern - This ratio can provide information about the pages/features most frequently used.
6. User Error Rate - how often users make a mistake during a specific task. 
7. Abandonment Rate - % of users abandoning a task

1. Net Promoter Score (NPS) - On a scale of 0-10how willing they are to promote you to their network
2. System Usability Scale (SUS)- one of the most popular questionnaires used to assess the usability of a product. It consists of 10 statements that users need to rate on a five-point scale from strongly agree to strongly disagree.
3. Customer Satisfaction Score (CSAT) - measures users’ satisfaction with your website or webapp. After they attempt a task, regardless of whether they manage to achieve its goal or not, have them answer one or a few questions about how difficult the task was.
