Value-First
Users shouldn't have to commit before they understand why they should. A strong onboarding experience leads with value. It is important to give users a clear sense of what the product does and what it offers them.
Personalization
Asking a few intentional questions early on can tailor the experience to the user's needs, goals and preferences from the very first interaction. This signals to the user that the product was built with them in mind.
Clear Progress Indication
If users can't see how long something will take, they won't feel motivated to keep going. Progress indicators help solve this problem by giving users a clear idea of where they are and what's left. Seeing the finish line makes it easier to cross it.
