This question's explanation and your answers so far.
問 99
Incorrectア
This is a single straight chain: Top page → Store list page → N-town store introduction page → Prize page. To reach the prize page a user must always pass through the N-town store introduction page, so requirement 2 (increasing the number of visits) is met; however, it takes as many as three clicks to get from the top page to the prize page, so more users drop out on the way. The announcement is made on the top page, but the target page is far away, so requirement 1, “smooth navigation”, is not satisfied.
Incorrectイ
A link is drawn directly from the top page to the prize page, so the prize page can be reached in one click, and requirement 1, “smooth navigation”, is satisfied. However, the prize page is not connected to the N-town store introduction page at all, so users who come for the prize draw never see the N-town store introduction page. It contributes nothing to requirement 2, “increasing the number of visits to the N-town store introduction page”, so it is not appropriate.
- ウ
正解 The correct answer is ウ. This question asks you to choose the page structure (site layout) that satisfies two requirements at the same time. Requirement 1 is “smooth navigation from the top page to the prize page”, and requirement 2 is “increasing the number of visits to the N-town store introduction page”. In structure ウ, a link is drawn directly from the top page to the N-town store introduction page, so a user who clicks the announcement on the top page reaches the prize page in only two clicks: Top page → N-town store introduction page → Prize page (requirement 1 is met). At the same time, the only arrow entering the prize page is the one from the N-town store introduction page, so every user who wants to enter the prize draw must pass through the N-town store introduction page, and the number of visits to that page is certain to increase (requirement 2 is met). In addition, the existing route Top page → Store list page → N-town store introduction page is still there, so the normal path for users who are looking for a store is not damaged either. ウ is the only structure that satisfies both requirements.
Incorrectエ
There are two routes into the prize page: one from the store list page and one from the N-town store introduction page. Users will choose the shorter route Top page → Store list page → Prize page, so they can bypass the N-town store introduction page and still reach the prize page. In other words, the structure is not built so that users must pass through the N-town store introduction page, so the increase in visits required by requirement 2 cannot be reliably obtained.
- When you design the structure of a website (a site map or a page-transition diagram), consider two things together: reducing the number of clicks needed to reach the target page so that navigation is smooth, and placing the page you want users to pass through on their route. Even with the same number of pages, a different way of drawing the links greatly changes the path users take.
- When you want to increase the number of visits to a particular page, it is effective to make that page the only way through to the destination (a relay page that must be passed). Conversely, if even one bypass route to the destination exists, users will take the shorter one, and the page you wanted them to pass through will simply be skipped.
