Which of the following is a common web design mistake?

Overloading a webpage with too much information is considered a common web design mistake because it can overwhelm visitors and create a negative user experience. When a webpage is cluttered with excessive text, images, or interactive elements, it can be difficult for users to find the information they need quickly and efficiently. This can lead to increased bounce rates, as users may leave the site in frustration, and can also make the website appear less professional or credible.

In contrast, implementing a responsive design, utilizing high-quality images, and improving page load speed are all best practices in web design. A responsive design ensures that the website functions well on various devices and screen sizes, high-quality images can enhance visual appeal, and efficient page load speeds contribute to better user retention and satisfaction. Each of these practices supports a user-friendly experience, while overloading a page does the opposite by detracting from usability and accessibility.
