如何创建Sitemap文件
Sitemap的格式有XML， ROR， Text， HTML等。Google 可接受多种格式的 Sitemap，但 Google 鼓励使用采用 Sitemap 协议的 Sitemap。因为这使网站所有者可以提供除网址以外的其他有关网页的信息。Google还希望网站所有者只创建一个Sitemap 文件供所有搜索引擎使用。Sitemap不论格式，均具有相同的指南。
创建Sitemap文件几种方法：
一、在sitemaps.com网站在线创建Sitemap文件
它支持创建XML， ROR， Text， HTML等格式的Sitemap文件
二、在www.sitemapbuilder.net网站在线创建Sitemap文件
用它在线创建sitemap文件也相当不错
三、
如PJblog在网站根目录下有一个sitemap.asp文件，执行这个文件自动创建本网站的Sitemap文件
五、利用代码工具自动生成Sitemap文件
制作过程说明：（L-BLOG为例）
将以下代码复制到本地存为sitemap.asp或sitemap.php，上传到你的服务器网站的根目录下，运行一下就可以在你指定的目录中（建议最好是指定为根目录）自动生成一个sitemap.xml文件了。

参数说明:
$website--你的域名
$page_root--你的站点的绝对路径
$changefreq--更新时间单位 "always"(始终), "hourly"(小时), "daily"(天), "weekly"(星期), "monthly"(月), "yearly" "never"(从不)
$priority--更新频率
$allow_dir--允许列表的目录
$disallow_dir--禁止列表的目录
$disallow_file--禁止列表的文件类型
最后进入google提交页面：
进Google 网站管理员工具，有gmail的可以用gmail直接登录。登录后把生成的xml文件地址按步骤提交就可以了。
注：你的网站如果增加了新的页面，可以在增加完后再运行一下sitemap.asp或sitemap.php，并再重新提交一下sitemap.xml文件，这样就可以保证sitemap.xml文件的不断更新了！
*********************
补充：
另外向雅虎提交Sitemap：在“雅虎站长工具”里的“我的网站收藏”里输入你的博客网址，点击“加入搜藏”，然后点击“开始认证”，在页面头部加入雅虎要求你在META里加入的代码，更新。完成之后点击“提交认证”即可。
雅虎认证通过后点击“Sitemap/RSS”的“管理”，输入sitemap.xml，点击“添加Sitemap/RSS”，由于雅虎的Sitemap必须是.txt格式的文件，而我们尚没有生成txt格式的Sitemap的插件，所以这里我们只能提交RSS了，输入rss/（不要忽略/），提交即可。
