1.网站页面HTML优化。这点是最基本的。困为脚本语言需要用户访问执行，速度慢。内容在用户访问时临时产生。没形成固定的文件。如果你网站改造成生成HTML网页麻烦的话，可以用URL重写。这样也可以将动态网页地址重写成静态地址。但效果没生成静态网页存在硬盘里的效果好。

2.网站的链接的优化。网站链接是你告诉搜索机器人和您的用户你网站内容的方法。所以链接策略也是网站内部结构优化很重要的一个元素。链接策略包括目录及URL的写法，导航链接，文内链接，网站地图。

目录及URL的写法:

A。目录层级:

1.用逻辑的方式安排目录.首页->栏目页->内容页。

2.目录结构最好用一级到二级。不要超过三级。

3.把所有网页都放在根目录当中。

B。URL静态化:

去掉url中的“？”和“=”等符号,用“/” 代替.

C。URL的写法:

1.目录和文件包涵关键词:可采用英文和拼音的形式。如普洱茶网站下有普洱茶商城可以http://www.cn-puer.com/puershop.

2.如果URL中有多个关键字需要分隔。请不要用下划线，请用”-”.

导航链接:

A。主导航醒目清晰充分：采用带有关键词的文字链接，尽量采用符合用户搜索习惯的词语。

B。列出当前页所有的路径：如：您当前位置：首页 -> 三七商城-> 三七粉您当前位置：首页 -> The Face Shop 商城

C。为每个导航链接添加TITLE: 如普洱茶

D。不要用Java***或用Falsh做导航链接。因为脚本和Flash搜索机器人无法识别。搜索机器人也就无法找到你的导航。对搜索机器人最友好的就是HTML了。

文内链接:

在您网站内容文章内的关键字上请加上你首页的链接，如果文章很长，请加上上一篇和下一篇链接分成多篇内容。

A。确认网站内没有死链接。死链接就是网页不存在，但链向该页的链接还在的情况。请不要让这种情况产生。

B。网站地图超过100条链接，请用分页来制作.如:9 7 [1] [2] [3] [4] 8 :

C。生成网站的XML格式的SiteMap文件放在网站根目录中。并在google网站管理员工具中提交。

3。网站关键词优化: 网站关键词优化包括关键词的分布和密度，相关关键词的选用，关键词Tag的应用。

关键字分布与密度:

A。关键词的选择:一个页面确定3个以内的核心关键词,围绕核心关键字进行排列组合产生关键词组或短句;核心关键词可以选择页面内出现最多的词语,要符合搜索者的心理,不要用意义太泛的关键词.

B。关键词的分布:无所不在，有所侧重。在下面这些地方用一次关键词：网页标题，说明标签，正文标题，网址URL，黑体，斜体，网页的最开始部分。

C。关键词的密度 :关键字密度一般在 1% 到 7% 较为合适.

关键词相关性控制:

在内容页增加同类文章列表和相关文章列表.以添加内容页的相关性，减小信噪比.

关键词Tags的应用:

针对热门的关键词制作Tags系统，增加页面间的相关性，提升关键词的排名.

4.页面的优化: 页面的优化包括Title优化，Meta优化，脚本优化，CSS优化，字体标签优化，布局优化，框架优化和页面去冗优化.

Title及Meta的优化:

A。Title
Title简短精炼，高度概括，含有关键词，但关键词不宜过多，不要超过3个词组。前几个词对搜索引擎最重要，因此关键词位置尽量靠前。最好将title组织成符合语法结构和阅读习惯的短句或短语，避免罗列式title。Title的长度最好不要超过40个字符。每个页面的title不要完全相同。

B。关键词（Keywords）
keywords书写的关键是每个词都能在内容中找到相应的匹配

C。描述(De***ion)
描述中出现关键词，与正文内容相关, 同样遵循简短原则，字符数含空格在内不要超过200个字符,补充在title和keywords中未能充分表述的说明.

脚本优化:

A。不要用脚本制作导航链接,如用document.write显示正文，会影响搜索引擎对页面内容的搜索

B。将脚本文件作为外部文件使用.如：将java***脚本置入一个.js扩展名的文件<*** src=”脚本名称”>; 将脚本源代码移至源码底部.

CSS及字体标签优化：

通过css控制HTML标签的风格,注意把所有css文件单独存放在外部文件中，如下：

.在文章标题或者导航链接不宜采用统一的CSS，应适当才采用和或者标红. 布局及框架优化:

布局简洁，减少Table嵌套，加快网页加载速度。这样才利于搜索引擎的收录。最好采用现在流行的DIV+CSS网页布局模式。优点是网页加载速度极快。但调DIV+CSS有点难调。不要用IFRAME或Frame框架网页。搜索对用IFRAME框架的网页很难收录。

页面去冗优化：

页面去冗:去掉冗余代码和空格,正常情况下一个页面的文件大小在20K左右，最好不要超过100K .脚本和CSS采用外部文件的形式.

采用DIV+CSS的形式，减少表格嵌套,尽量保持页面简洁，内容部分要尽量大于代码, 图片用压缩格式，图片加上alt标签。
