The most useful metrics to measure the effectiveness of UX Design are:
A bounce occurs when the user leaves the site after visiting only one page within a few seconds, in the digital world there are deferred user behaviors depending on the sector and the specificity of the products or services treated, usually an optimal bounce rate should be lower to 60% of total users.
Time of Stay
Dwell time is a metric that indicates the average dwell time that users spend on a given page. A low residence time can indicate a content that is not consistent with the users' expectations, while an excessively high time range may be the indicator of a page where the information architecture is too complex.
The optimal loading time of a web page is a topic that has been debated that depending on the interpretations, its optimal maximum duration varies, in reality the most sensitive time for users is the time to display the first contents, thanks to a correct balance. between programming and UX Design it is possible to make even the heaviest web pages immediately usable and navigable, allowing a progressive loading.
The conversion rate is a figure that indicates the percentage of visitors who have completed a specific action, such as filling out a form or, in the case of an e-commerce, a purchase. This is a fundamental metric to understand if the goals of the digital project are being achieved.
