Whether modal or not, most overlays appear at the wrong time, interrupt users during critical tasks, use poor language, and contribute to user disorientation.
Provide value to users before asking them to receive your app’s notifications; tell them what the notifications will be about. Don’t send notifications in bursts; make it easy to turn them off.
Look beyond surface-level qualities to assess UX value. A design that looks (or sounds) good does not mean that it is. Good websites contain engaging features that help people accomplish their goals.
A generic Get Started call-to-action attracts clicks, but also misleads users and acts as a roadblock for those looking to get information about the company.
Users spend most of their time on other sites. This means that users prefer your site to work the same way as all the other sites they already know. Design for patterns for which users are accustomed.
To transition images from mobile to desktop, consider relative screen space and information density. Pay attention to cropping, scaling, and proportions.
Modal ads, ads that reorganize content, and autoplaying video ads were among the most disliked. Ads that are annoying on desktop become intolerable on mobile.
Whether you adopt a flat-design style or not, interactive components must retain sufficient cues to suggest clickability. Signaling clickability with cues such as borders, color, size, consistency, placement, and adherence to web standards can give interactive components the proper look.
Quality assurance impacts the user experience: when things don’t work, users question their understanding and develop superstitions and inefficient workarounds.
The ten most egregious offenses against users. Web design disasters and HTML horrors are legion, though many usability atrocities are less common than they used to be.
Slow page rendering today is typically caused by server delays or overly fancy page widgets, not by big images. Users still hate slow sites and don't hesitate telling us.
Structure and navigation must support each other and integrate with search and across subsites. Complexity, inconsistency, hidden options, and clumsy UI mechanics prevent users from finding what they need.
Application usability is enhanced when users know how to operate the UI and it guides them through the workflow. Violating common guidelines prevents both.
