With the coming of Google webmaster tools, having a dynamic sitemap in the Google sitemaps compliant XML-Sitemap has become one of the most important steps of Search Engine Optimization. But creating sitemaps manually for dynamic websites blogs can be very much uncomfortable. For the purpose, the Google Sitemap Generator Plugin for wordpress has been released. This plugin creates a sitemap.xml file in the web server and updates this file whenever a new page or post is created or whenever there is any changes in the blog. Also, every time you edit or create a post, your sitemap is updated and all major search engines that support the sitemap protocol, like ASK.com, Google, MSN Search and YAHOO, are notified about the update.
In other words, with this new plugin, the blogger no longer needs to update his sitemap as everything is done by its own. All the blogger has to do is install this plugin in the wordpress blog.
