页面的关键词算法排名都会高。域名等级和页面等级都是由链接广泛度和流量所决定的,但是页面等级在不断变化的算法中已经变得越来越不重要。
4.3 关键词 Keywords
关键词是搜索的依据,也是SEO的中心工作。从形式上说有Title,Meta,和网页内容。
Title 重要性排在第一位的,我有一些网页没有用meta,内容是图片,只是Title包含关键词依然排在google第一页。
网页内容 关键词密度非常重要,也是大家经常去作弊的地方。作弊的方法在本文不予讨论,提供4种不作弊不改变内容而提升关键字的方法:
(1)url路径包含关键词,如www.Keywords.com/Keywords/Keywords/Keywords.html
(2)隐性注释 <!-- Keywords, -->
(3)Alt注释
(4)<h>关键字标题注释
Meta 给大家看一下IBM的META标签大家就知道该怎么做了
