sitemap制作

http://teachmyself.blog.163.com/blog/static/18881422920119895435272/

sitemap.xml是一种站点地图协议,此协议文件基于早期的robots.txt文件协议,并有所升级。向搜索引擎中提交了sitemap.xml的 网站将更有利于搜索引擎网页爬行机器人的爬行索引,这样将提高索引网站内容的效率和准确度。

  一共有六个标签,changefreq:页面内容更新频率;

  • lastmod:页面最后修改时间;
  • loc:页面永久链接地址;
  • priority:相对于其他页面的优先权(这个标签可以不使用);
  • url:相对于前 4个标签的父标签;
  • urlset:相对于前5个标签的父标签。

  你可以向搜索引擎提供多个Sitemap文件,但提供的每个Sitemap文件包括的网址不得超过50,000 个,并且未压缩时不能大于10MB 。

  • 向Google提交网站地图Sitemap: 通过网址http://www.google.com/webmasters管理提交;
  • 向Yahoo!提交网站地图Sitemap: 通过网址http://siteexplorer.search.yahoo.com管理提交;
  • 向MSN提交网站地图Sitemap: 用URL直接提交:http://api.moreover.com/ping?u=http%3A//your.domainname /sitemap.xml。这是向MSN直接提交网站地图的后门URL。注意”:”被%3A替换掉。
  • 向ASK提交网站地图Sitemap: 直接提交。http://submissions.ask.com/ping?sitemap=http%3A//your.domainname/sitemap.xml。注意”:”被%3A替换掉。

sitemap.xml文件格式如下:

复制代码
<?xml version=”1.0″ encoding=”UTF-8″ ?>
<urlset xmlns=”http://www.sitemaps.org/schemas/sitemap/0.9“>
<url>
  <loc>http://www.grzz.com.cn/</loc>
  <lastmod>2009-04-27</lastmod>
  <changefreq>daily</changefreq>
</url>
<url>
  <loc>http://www.grzz.com.cn/index.html</loc>
  <lastmod>2009-04-27</lastmod>
  <changefreq>weekly</changefreq>
</url>
</urlset>

那怎么制作sitemap.xml。最笨的方法就是按照这六个标签的规则,自己手写了。

如 果网站的页面太多了,这个就会变成了一个超级郁闷的体力劳动。于是就有不少sitemap.xml的生成工具出现了,但是现在大部分的 sitemap.xml生成工具都是在客户端输入网址,让工具在网站自行寻找链接生成,这样的模式,Rookie感觉效率比较低,而且没有办法对生成链接 做控制。终于在网上找到了一个比较好的方法,适用于将内容生成静态页面的网站。有人将生成sitemap.xml的功能,写成了asp和php的页面,在 页面上可以控制需要生成哪些链接。按照你的需要修改页面后,再把页面上传到你的网站空间,访问这个页面就是你所需要的sitemap.xml文件。然后就 保存成为xml文件格式,再上传到你的空间,再将链接提交给支持sitemap.xml的搜索引擎。
