Pop-ups can be modal, blocking interaction with the background, or non-modal, allowing users to interact with the page while the pop-up is active. Pop-ups should be used sparingly and only for important information at the right moment. Otherwise, they can feel intrusive and annoying.

If pop-ups are necessary, follow these best practices:

• Ensure relevance. Avoid interrupting users in the middle of a task. Wait until the pop-up content is contextually relevant. For example, onboarding tooltips work better after users have had time to explore the interface.
• Be polite and highlight benefits. Since users dislike pop-ups, make them respectful and clearly explain the benefits. For example, when asking for an email, specify what users will gain by subscribing.
• Add a playful tone. Pop-ups are less irritating when they include a friendly, personal touch or a lighthearted joke. This is especially useful for cookie notifications or feedback requests.
• Offer an easy exit. Always provide clear and easy ways to close the pop-up, reducing frustration.
