The Sitemap Protocol allows you to inform search engines about URLs on your websites that are available for crawling. In its simplest form, a Sitemap that uses the Sitemap Protocol is an XML file that lists URLs for a site.
The protocol was written to be highly scalable so it can accommodate sites of any size. It also enables webmasters to include additional information about each URL (when it was last updated; how often it changes; how important it is in relation to other URLs in the site) so that search engines can more intelligently crawl the site.

Download the Zip-Archive and extract all files into your wp-content/plugins/ directory. Then go into your WordPress administration page, click on Plugins and activate it. You will now see the plugin called “Sitemap” under the “Options” menu. You can alter the default change frequencies, filename and other options there. Click once on “Rebuild Sitemap” to create your sitemap the first time.
Once your sitemap is generated, you now need to inform Google. Submit a Sitemap using Google Webmaster Tools. Google uses your Sitemap to learn about the structure of your site and to increase our coverage of your WebPages.
