DPS BLOGGERS CODE TO USE: <!– ddsitemapgen –> Copy from arrow to arrow including the arrows. Then Go into your blog admin and click “WRITE”. Select “Page” (instead of Post). Add a title such as sitemap. Then in the text edit bar click the “html” button. Paste <!– ddsitemapgen –> and then click update. Click Publish and you have just added a sitemap to your blog.
