There are a few key things to consider when publishing a blog through Wordpress' admin panel in order to optimize your site for search engines. First, be sure to use keywords throughout your post - in the title, in the body, and in the tags and categories. Second, make sure your site is linked to from other websites with high authority; this will help improve your site's ranking. And finally, always keep your content fresh and up-to-date; search engines rank sites higher that are continually adding new content.
