If this is a relaunch of an existing website, then I assume that there are probably artefacts that capture some aspects of the user journey or analytics of their interaction with the previous website.
I don't know if there are specific or accepted names for these, but I can think of the type of journeys that people might be interested in.
- Ideal path, where everything goes smoothly and the user reaches their goal in the shortest amount of steps and/or time
- Worst-case scenario, where nothing goes right, and the user experiences many obstacles or delays in attempting to reach their goal
- Most common path, where the journey captures the most frequent or typical scenario
- Full journey, where every possible combination of paths are documented, which is often a little bit too overwhelming to see all at once (if it even makes sense), so it is often broken up or interactive so you only see sections of the full picture.
Keep in mind that this can then also be multiplied when you have multiple users, multiple use cases and if you are doing a comparison to other similar websites.
I think that covers pretty much all of the user journeys that you might expect to come across.
