 网站优化中html标签meta的强大功效不容忽视,一个好的meta标签设计可以大大提高网站被搜索到的可能性,下面我们来认识一下meta。


       meta是html语言head区的一个辅助性标签,用来在html文档中模拟http协议的响应头报文。它位于html文档头部的标记和标记之间,它提供用户不可见的信息。


       meta的属性有两种:name和http-equiv。name属性主要用于描述网页,对应于content(网页内容),以便于搜索引擎机器人查找、分类(目前几乎所有的搜索引擎都使用网上机器人自动查找meta值来给网页分类)。这其中最重要的是description(站点在搜索引擎上的描述)和keywords(分类关键词),所以应该给每页加一个meta值。几乎所有的网页里,我们可以看到类似 下面这段的html代码:

<head>  

 <meta http-equiv="content-Type" content="text/html; charset=GB2132" /> 
 <!--用以说明主页制作所使用的文字以及语言;GB2132,就是国标汉字码,又如英文是ISO-8859-1字符集,还有utf-8、shift-Jis等字符集;-->

 <title>网页标题</title><!--网页标题-->
 <meta name="KEYWords" contect="放关键字的位置"><!--向搜索引擎说明你的网页的关键词-->
 <meta name="DEscription" contect="放关描述的位置"><!--告诉搜索引擎你的站点的主要内容-->

</head>
Copy after login

     

 以上是meta标签的一些基本用法,其中最重要的就是:Keywords和Description的设定。这两个语句可以让搜索引擎在“浩瀚如海”的网络空间中能准确的发现你的网站,吸引更多的人访问你的站点!根据现在流行搜索引擎(Google,Baidu等)的工作原理,搜索引擎先派机器人自动在www上搜索,当发现新的网站时,便于检索页面中的Keywords和Description,并将其加入到自己的数据库,然后再根据关键词的密度将网站排序。


 现在我们已经知道Keywords和Description的用法,接下来我们更关心的是:Keywords和Description怎样设置才是最合理的?


 寻找Keywords和Description的合适设置的技巧是:到Baidu、Google等著名搜索引擎,搜索与你的网站内容相仿的网站,查看排名前十位的网站的meta关键字和描述,以作参考将它们用在你的网站上。
