User experience is often ambiguous, making it challenging to identify the right UX metrics and KPIs. Design and product teams want to know whether their solutions work while stakeholders are interested in various projects’ ROI.
Metrics are the signals that show whether your UX strategy is working. Using metrics is key to tracking changes over time, benchmarking against iterations of your own site or application or those of competitors, and setting targets.
Although most organizations are tracking metrics like conversion rate or engagement time, often they do not tie these metrics back to design decisions. The reason? Their metrics are too high level. A change in your conversion rate could relate to a design change, a promotion, or something that a competitor has done. Time on site could mean anything.
UX strategists need to take charge of the metrics for online experiences.

Customer satisfaction is important for retention, conversions, and other marketing and sales metrics that ultimately impact the organization’s bottom line. UX KPIs benchmark performance and track progress to ensure companies meet various UX goals and objectives.
By monitoring these metrics, designers can identify areas of improvement and make data-driven decisions to enhance the user experience. For example, if the task completion rate is low, designers may need to simplify the design or provide clearer instructions to make it easier for users to complete the task.
Like any measurement framework, there are two types of UX metrics:
The challenge with measuring user experience is that many metrics are qualitative. Quantitative is relatively simple to analyze; numbers either go up or down. Analysts and stakeholders must treat qualitative data with greater scrutiny, as it’s easier to misinterpret or bias data (purposely or incorrectly).
Understanding the difference between KPIs and UX metrics is critical. They’re often confused with each other, but they’re two separate things.
Most metrics are marketing-oriented, not experience-oriented. Unique visitors can tell you whether your marketing campaign worked and social mentions can tell you whether you’ve got a great headline, but these metrics do not reveal much about the experience people have had using a site or application.
