What design factor might discourage Internet users from returning to a website?

Long download times can significantly deter Internet users from returning to a website because they create a frustrating experience. Users today expect swift access to content, and if a site takes too long to load, it can lead to impatience and dissatisfaction. This often results in visitors leaving the site before it has fully loaded, thereby increasing the likelihood of them not wanting to return in the future. In contrast, visually appealing graphics, interactive features, and clear navigation are elements that typically enhance user experience and engagement, rather than discourage users from returning. Therefore, long download times are a critical factor that can negatively impact user retention.
