Before start creating a walkthrough, first, define a clear goal for it. Ask yourself what type of behavior you aim to drive from your end-users. If you can focus on this goal while creating the tour, so do the people who will follow that route.
Reaching a certain page, or clicking on a certain button might be the end result of a single guide. Be sure that all end results of any guide in sync with the value your product offers.
Do you want them to complete a key action or walk through a confusing process? How do these contribute to the overall user experience you provide in-app?
Once you set an objective, the only thing to do is designing the simplest and engaging guided path that brings the user to that goal.
Hint💡: Keep an eye on any active guide's Step Analytics to check whether it has a particular step making people leave the tour. Then, change it to increase the user number, reaching tour goals.
