在优化出现之初，Meta属性是被广大站长所看重的，但后来由于站长们过度的使用SEO，使得Meta描述的权重有所降低，虽然，有所变化，但是，META描述对搜索结果的影响还是有的。
ETA描述通常位于网页的
标签中，在
下方。一般由以下几个部分组成：<BR><meta http-equiv=”Content-Type” content=”text/html; charset=gb2312″ /></P>
<P><meta name=”keywords” content=”<SPAN>站长百科,建站交流,网站推广,建站知识,站长</SPAN>” /><BR>//网页关键字</P>
<P><meta name=”description” content=”<SPAN>是国内最大的站长类百科知识网站，通过wiki 平台，站长可以分享自己的知识，共建站长自己的知识库</SPAN>” /><BR>这是META描述必须有的固定语句格式，其中charset声明了网页的编码<SPAN id=more-1022></SPAN></P>
<P>keywords属性：大多数站长认为keywords中的越多越好，其实这是不对的，物极必反，过多的关键字堆砌会被搜索引擎视为不友好的 方式，轻则降权，重则封站。实践证明，keywords中的关键字数量最好控制在5-15个左右。建议越短越好，提取整个网页的重要元素，</P>
<P>description属性：和keywords一样，description属性也是求精不求丰,适当的description描述对于网页的权重是至关重要的,description描述一般为或长或短的一句话，但这句话中包含了重要的关键字和展示给访客的信息，</P>
<P>在整个META中，最为重要是keywords和description两个属性。这两个属性决定了网页的关键字密度、描述所涉及的关键字等等。在对搜索引擎的测试中我发现，有时引擎给出的搜索结果的标题与关键字并不匹配，而与网页描述匹配，这就是description属性的功劳。</P>
<P>实际上并非所有搜索结果都是严格按照keywords关联、description描述的结构。大部分网页简介提取的是html代码中的信息。造成这种现象一小部分是因为meta描述写错了，更多的是的算法使然。但是不能因此而忽略meta描述的重要性。</P>
<P>另很多站长头痛的还有模板设计时该如何融入meta标签元素。如你所知，每个网页都应该有不同的meta描述，N个网页有相同的描述会被搜索引擎认为是作弊。大部分都有直接控制首页meta标签的功能，而控制频道页、栏目页和内容页的meta描述就相对困难。其实大家可以在频道页和栏目页插入对应的META标签（如果程序有的话则插入，没有可以使用字符替换标签）。</P>
<P>内容页的keywords属性使用网页的tags标签，description属性使用文章导读,meta描述是站长SEO的第一步也是很重要的一步，控制好精确度对一个网站初期发展的成败是至关重要的。</P>
