Although the Title tag isn’t really a meta tag it remains one of the most imporant factors when it come to your rankings. Its located at the top of your html code between the head tags along with other meta tags you choose to include.

Google will also occasionally use the description tag when related content can’t be found so its always a good idea to create this as well.

SEO Tip: I highly recommend a great plugin for WordPress called the All in One SEO Pack which will handle both of these tags, and overrides the Titles created by Wordpress. It also automatically updates your header info so you don’t have to mess with any code.
