Suppose the path (a, b) is returned, and further suppose that it is an embedded tree. This means that many users went from a to b, but that they visited different pages on the way to b (for example, some may have used the path (a, c, d, e, b), while others used (a, x, y, z, b), etc.). This implies that the path from a to b is not clear, and that the website should be redesigned to fix this problem. Ideally, a link to b would be added to a to make the path clear.
