If you are serious about getting traffic to your WordPress blog…
I am going to highly recommend that you use a custom permalink structure in order to maximize your search engine visibility. This is another important aspect of SEO.
Your permalink structure involves how the link (url) to a single blog post is created when you publish a post.
While the Google XML Sitemap plugin for WordPress works automatically to communicate changes to your blog sitemap to the search engines (which enhances blog post indexing)…
There is one option provided by the plugin that you may want to configure to further enhance your search mojo with this plugin. This enhancement involves your updated sitemap communication with Yahoo.
Right out of the box, this fantastic plugin automatically generates and updates an XML sitemap for your blog and notifies top search engines that your blog sitemap has been updated.
