网站的链接结构是指页面之间相互链接的拓扑结构

网站的链接结构是指页面之间相互链接的拓扑结构。它建立在目录结构基础之上，但可以跨越目录。形象的说：每个页面都是一个固定点，链接则是在两个固定点之间的连线。一个点可以和一个点连接，也可以和多个点连接。更重要的是，这些点并不是分布在一个平面上，而是存在于一个立体的空间中。一般的，建立网站的链接结构有两种基本方式：
The link structure of a website refers to the topological structure of links between pages. It is built on the basis of directory structure, but can span across directories. Visually speaking, each page is a fixed point, and a link is a line connecting two fixed points. A point can be connected to one point or multiple points. More importantly, these points are not distributed on a plane, but exist in a three-dimensional space. Generally, there are two basic ways to establish a website's link structure:
树状链接结构（一对一），这类似DOS的目录结构，首页链接指向一级页面，一级页面链接指向二级页面。这样的链接结构浏览时，一级级进入，一级级退出，条理比较清晰，访问者明确知道自己在什么位置，不会“不知身在何处”，但是浏览效率低，一个栏目下的子页面到另一个栏目下的子页面，必须回到首页再进行。
Tree like link structure (one-on-one), similar to the directory structure of DOS, where the homepage link points to the first level page and the first level page link points to the second level page. When browsing through such a link structure, one level of entry and one level of exit are relatively clear, and visitors have a clear understanding of their location and will not "not know where they are". However, browsing efficiency is low. From a subpage under one column to a subpage under another column, they must return to the homepage before proceeding.
星状链接结构（一对多），类似网络服务器的链接，每个页面相互之间都建立有链接。这样浏览比较方便，随时可以到达自己喜欢的页面。但是由于链接太多，容易使浏览者迷路，搞不清自己在什么位置，看了多少内容
A star like link structure (one to many), similar to a network server link, where each page establishes a link to each other. This way, browsing is more convenient and you can reach your favorite pages at any time. But due to too many links, it is easy for viewers to get lost and not know where they are and how much content they have read
