Characteristics of EPPO Topics: Stay on One Level

One of the less obvious but more important characteristics of an Every Page is Page One topic is that it stays on one level. As with the other characteristics I have discussed in this series, being standalone, having a specific limited purpose, and establishing its context, staying on one level is not an ideal, but a common feature of millions of page-one topics on the web. What makes this characteristic worth pointing out is that it is something a topic does not share with books.
