In-app guidance is crucial for improving user experience and reducing churn, as it provides users with the support they need to use products seamlessly. Effective in-app guides anticipate and remove friction for users by offering product tours, tooltips, onboarding checklists, and self-serve support options throughout their journey. To build successful in-app guidance, segment your users, conduct UX research, add relevant in-app widgets, optimize messaging, and measure success through user feedback and engagement analytics.
