Sitemaps.NET
Sitemaps.NET is a website plugin that automatically generates an XML sitemap of your content. Sitemaps.NET reuses a site’s existing ASP.NET sitemap and automatically mirrors changes in your site to search engines.
Features
- Quickly generate XML sitemaps for search engines
- Integrates with the ASP.NET sitemap functionality, automatically mirrors changes to search engines
- Specify the priority and update frequency of content within your site on a page by page basis.
- Simple plug in installation

- Add the
SitemapHandlerto your web.config’shttpHandlersection.<add verb="*" path="sitemap.axd" type="Newtonsoft.Sitemaps.SitemapHandler, Newtonsoft.Sitemaps"/>
The path will determine the URL you submit to search engines. In the example above, for this site, the generated XML would be accessed with the URL http://www.newtonsoft.com/sitemap.axd.
