URL命名中如果含有关键字，这对关键字的排名是非常有利的。现在各大搜索引擎都能够自动根据拼音来判断汉字关键字。以牛商网为例，牛商网的关键字为：网络营销培训，在百度排名第一。先看牛商网的内容URL命名，如：《城乡导报》：让网络营销变成真正的赚钱工具，这篇文章的URL链接为：http://www.nsw88.com/Article/chengxiangdaobaorangwangluobianchengzhenzhengdezhuanqiangongju_1.html，我想对于刚入SEO的人来说会对这个长长的URL感到惊讶。其实不然，现在的搜索引擎技术越来越先进，对于这长长的URL并不会影响其收录，由于此URL是以标题拼音命名的，含有其想推广的长尾关键字，更有利于搜索引擎的关键字排名。
纵观现在中国国内的企业网站管理系统和CMS，还没有那套企业网站管理系统和CMS考虑自动根据标题名以拼音命名静态URL名称的因素。25亿企业网站管理系统是现在企业网站管理系统当中的新秀，采用C#+MSSQL技术开发而成，从各方面完全考虑SEO优秀因素。25亿企业网站管理系统对URL的命名用户可以自定义，但系统默认是自动根据标题名以拼音命名静态URL名称。
下面深刻讲解C#(asp.net)自动根据标题名以拼音命名静态URL名称，以25亿企业网站管理系统中的源码作为实例。
在25亿企业网站管理系统的COMM公共层对汉字转换为拼音的函数进行了封装，文件名为：Pinyin.cs。
在前台用js异步传输调用，js代码如下：
<script type="text/javascript">
function pinyin()
{
try
{
if(Request.QueryString("id")!="")
{
}
else
{
$("txtStaticPage").value=Company.Templates.comm.PinYin($("txtInfoTitle").value).value;
}
}
catch(e)
{
}
}
</script>
其中txtStaticPage既为TextBox控件，显示转换后的拼音。
下面附汉字转换为拼音的函数:
public class Pinyin
{
/// <summary>

由于25亿企业网站管理系统对URL格式自定义采取了二种方式，一种是带以.html结尾的文件名，如：格式一(如：www.25yi.com/helphtml/shouquanxieyi.html)。另一种是不带.html结尾的文件名,如：格式二(如：www.25yi.com/helphtml/shouquanxieyi/)。所以只取以标题转换后的拼音的40个字符，以免格式二中的文件名过长。
C#(asp.net)自动根据标题名以拼音命名静态URL名称详解完成,表达非常简单，需要深刻体会，请研究25亿企业网站管理系统源码。
