WordPress SEO
A good way to help optimizing a WordPress website is to use the “All-in-One SEO Pack” plugin. When activated it adds several fields to the bottom of the posts or page interface, where one can add post/page-specific details, which will override… the default title, and allow a potentially more SEO-friendly description to be used.
