For your WordPress blog 2 types of Sitemaps are relevant. The first is the XML sitemap used by Google. The second is an ordinary sitemap for your visitors, which might also be used by Google by the way. But how to add them? Here’s howto.
For the XML sitemap I use the WordPress plugin created by Arne Brachhold. His plugin called Google Sitemaps, can be fully configured through the WordPress administration panel. It updates the sitemap automatically and sends the new data to Google. Here’s a link to my XML sitemap.
For the ordinary sitemap for your visitors, I use the plugin created by Aleister. His plugin is called Dagon Design Sitemap Generator and is also fully configurable through the WordPress admin panel. You’ll also see it by visiting a non-existent page because I added the following rule to the 404.php in my template.
< ?php echo ddsg_create_sitemap(); ?>
