Step 2: Login to http://www.google.com/webmasters/sitemaps
Step 3: Add a website
Step 4: Verify that you are the owner by uploading an HTML file or add a Meta tag
Step 5: Add a sitemap for that website
Class will be as follows :
using System;
using System.Xml;
namespace shop.BLL.Utility
{
public class SiteMapFeedGenerator
{
XmlTextWriter writer;
public SiteMapFeedGenerator(System.IO.Stream stream, System.Text.Encoding encoding)
{
writer = new XmlTextWriter(stream, encoding);
writer.Formatting = Formatting.Indented;
}
public SiteMapFeedGenerator(System.IO.TextWriter w)
{
writer = new XmlTextWriter(w);
writer.Formatting = Formatting.Indented;
}
///
/// Writes the beginning of the SiteMap document
///
public void WriteStartDocument()
{
writer.WriteStartDocument();
writer.WriteStartElement("urlset");
writer.WriteAttributeString("xmlns", "http://www.google.com/schemas/sitemap/0.84");
}
///
/// Writes the end of the SiteMap document
///
public void WriteEndDocument()
{
writer.WriteEndElement();
writer.WriteEndDocument();
}
///
/// Closes this stream and the underlying stream
///
public void Close()
{
writer.Flush();
writer.Close();
}
public void WriteItem(string link, DateTime publishedDate, string priority)
{
writer.WriteStartElement("url");
writer.WriteElementString("loc", link);
writer.WriteElementString("lastmod", publishedDate.ToString("yyyy-MM-dd"));
writer.WriteElementString("changefreq", "always");
writer.WriteElementString("priority", priority);
writer.WriteEndElement();
}
}
}
This is just a basic Google Sitemap, you can add elements for geographic info about the item or mobile sitemaps etc. You can find more info for that on: http://www.google.com/support/webmasters/bin/answer.py?answer=34657
You can use this class in an .aspx or .ashx file. I used an .aspx in the following (code behind) sample:
protected void Page_Load(object sender, EventArgs e)
{
Response.Clear();
Response.ContentType = "text/xml";
shop.BLL.Utility.SiteMapFeedGenerator gen = new shop.BLL.Utility.SiteMapFeedGenerator(Response.Output);
gen.WriteStartDocument();
gen.WriteItem("http://www.mysamplesiterocks.com/Default.aspx", DateTime.Now, "1.0");
gen.WriteEndDocument();
gen.Close();
}
