Also, its possible to add xml site map files for any additional urls you want to tell google about. For example I have not yet implemented an automatic sitemap for webstore feature, so I just created an xml file for now until I implement it. I have to maintain the xml file manually until then.
Format Example:
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
<url>
<loc>http://www.mojoportal.com/event-calendar-pro-product.aspx</loc>
<lastmod>2008-10-21</lastmod>
<changefreq>monthly</changefreq>
<priority>0.9</priority>
</url>
<url>
<loc>http://www.mojoportal.com/form-wizard-pro-product.aspx</loc>
<lastmod>2008-10-21</lastmod>
<changefreq>monthly</changefreq>
<priority>0.8</priority>
</url>
</urlset>
Best,
