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。
    asp程序代码:

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。
