Popups

Overview

Description

Popups are an interface element that appears on top of existing content to display a message, offer, form, or provide a call-to-action (CTA). Often triggered by user behavior such as scrolling, clicking a button, or even exit intent, popups are designed to grab the user’s attention and guide their interaction with the interface, but can also be used for system alerts, notifications, or to gather feedback.

Uses

  • Notifications and alerts: to inform users of important updates, errors, or confirmations.
  • Marketing and lead generation: to offer promotions, coupons, or to collect email addresses for newsletters.
  • vUser engagement: to solicit feedback through surveys or prompt users to complete tasks.
  • User guidance: to provide contextual information, such as help tips or instructions, when a user hovers over or clicks on an element.

Value to user

  • Alerting to critical information: users are more likely to find value in a popup that highlights something urgent, important, or that they would otherwise miss, such as an impending meeting deadline or a site-wide outage.
  • Confirming destructive actions: popups are useful for confirming irreversible actions, like deleting an account, to prevent accidental data loss and give the user a chance to reconsider.
  • Contextual guidance: when a popup appears as a natural response to a user’s action (like scrolling or pausing), it feels relevant and provides valuable, context-specific guidance rather than an interruption.
  • Saving screen space: popups and particularly popovers are excellent for displaying optional or supplementary information without cluttering the main interface, which is especially beneficial for minimalist designs and mobile devices.
  • Providing clear calls to action: a well-designed popup offers concise messaging and a clear call to action, making it easier for users to understand what they need to do next.

How they work

  • Overlay: popups appear over the main content, creating a temporary layer that draws focus to the new information or action.
  • Triggers: they can be initiated by specific user actions, like clicking a button, moving the mouse to exit the page (exit-intent), or after a set amount of time has passed on a page.
  • Disappearing act: a key characteristic is their transient nature; they can often be closed by clicking outside the popup area, completing an action, or simply by the event that triggered them ending

Best practices

  • Trigger contextually: show popups only when it is natural and relevant to the user’s current activity on the site, such as when they pause at checkout or interact with a specific feature.
  • Offer a clear exit: always provide an easy-to-find and easy-to-use close button to allow users to dismiss the popup and return to their task.
  • Prioritize user experience: design popups to be respectful of the user’s journey, solving a problem or offering a benefit rather than disrupting their flow for short-term gains.
  • Use concise messaging: keep the text in popups brief and to the point so users can quickly understand the information or request.
  • Ensure mobile responsiveness: given the prevalence of mobile usage, popups must be optimized to look and function well on smartphones and tablets.
  • Timeliness & relevance: trigger popups at appropriate moments, such as when a user is about to leave (exit-intent popups), rather than displaying them immediately or annoyingly.
  • Provide clear value: offer something genuinely useful, like a discount or helpful information, to incentivize interaction.
  • Non-intrusive design: ensure popups are easy to close and do not block the user’s essential tasks or primary flow.
  • Mobile optimization: design popups to be responsive and perform well on all devices, especially mobile phones, to prevent performance issues and poor user experiences.
  • Focus on a single goal: keep the message and the requested action clear and focused within a single popup to avoid overwhelming the use

Accessibility notes

  • Announce popups: when a popup is triggered, it should be clearly announced to screen reader users so they know their action has resulted in a new element appearing.
  • Maintain focus: the user’s focus should be moved into the popup when it appears, and when it is dismissed, focus should return to the element that triggered it.
  • Keyboard accessibility: ensure all interactions within the popup are fully operable via keyboard, including closing it.
  • High contrast: use color combinations with significant contrast between text and background to improve readability for users with low vision.
  • Clear dismissal: provide clear and accessible ways to close the popup, such as an “X” button or by allowing the user to press the Escape key.
  • Semantic HTML use appropriate semantic HTML elements to structure the popup, providing proper context for assistive technologies.
