Google Webmaster Central has created a new sitemap generator and released it to the general public. The new generator is open source and uses your webserver's traffic, its log files, or the files found on the server to quickly find the URLs on your site.
It ping Google blog search and creates the following sitemap files for you:
- XML Sitemaps for Web Search according to the sitemaps.org standard
- Mobile Sitemaps for mobile-friendly websites
- Code Search Sitemaps for source code that you make available to users
The generator is a server plugin that can be installed on Linux/Apache and Microsoft IIS Windows-based servers. For more information, check out the Google Sitemap Generator documentation.
