wordpress默认情况下设置固定链接，分类页面是有category路径的。出于SEO优化的考虑，网站的链接层次多，不利于蜘蛛的抓取，也就是说链接越简洁越好，链接的路径越少越好。在百度优化指南中，百度一直是建议站长们使用浅表的层次结构。

方法1：切换到主题目录，打开functions.PHP文件，添加如下代码，然后到wordpress后台中设置的地方，点击固定链接，保存即可生效。
extra_permastructs['category']['struct'] = '%category%';}方法2：基于插件WP No category Base上的代码，切换到主题目录，打开functions.PHP文件，添加如下代码，然后到wordpress后台中设置的地方，点击固定链接，保存即可生效。
