Simple Sitemaps is a free tool generating dynamic Google XML Sitemaps and HTML Site Maps as well a RSS Site Feed from one set of page data. All types of site maps help search engine crawlers to discover and index a Web site completely. Simple Sitemaps is suitable for smaller Web sites and requires PHP 4.3.1 or later installed on the Web server.

Simple Sitemaps helps you to save time, because both the XML sitemap and the RSS/HTML site map are dynamically created from the same data source.

The simple installation procedure is painless. Once you have the script running on your server, you can add new pages to all site maps by adding the URL, link depth (hierarchy level in your site's structure) and page title to a plain text file. Just upload the changed text file and Ms. Googlebot will refresh the XML sitemap as well as the HTML site map during her next visit, every 12 hours like a clockwork.

If you add a description and a few keywords per page, Simple Sitemaps generates a RSS 2.0 Feed for your Web site too. Most search engines make use of RSS feeds harvested anywhere on the net to discover new content, thus the RSS site feed will improve your search engine visibility.

It's that simple, really. Maintaining a plain list of pages is enough to provide your visitors with a current site wide hierarchical navigation, and search engine crawlers with a spider friendly list of all your pages.
