一、链接伪静态问题 1、分类链接，如：http://www.ikcrm.com/news?q%5Bnews_type_eq%5D=1应伪静态重写成http://www.ikcrm.com/news/type/1 2、标签链接，如：http://www.ikcrm.com/news?q%5Btags_blogs_tag_id_eq%5D=4应伪静态重写成http://www.ikcrm.com/news/tag/4 3、分页标签，如：http://www.ikcrm.com/news?page=2应为伪静态重写为http://www.ikcrm.com/news/page/2
二、标签使用问题 1、h1标签，每个页面有且仅可使用一次；h2标签每个页面可使用多次。（全站所有页面均须自从此规则） 2、首页h1标签重复使用 3、首页新闻列表页未使用h2标签,新闻标题使用h2标签 4、新闻中心（http://www.ikcrm.com/news）h2标签应分配给每条新闻标题
