Notes:

If you decide not to use the All-In-One-SEO-Pack plugin (or any of the other plugins that control meta tags), you can use these code snippets instead. You would need to manually edit our header.php file, to change the existing TITLE code to this. This code simply determines which page is being shown, and displays the appropriate search-friendly TITLE for that page.

<?php 
if ( is_home() ) {
      echo'<TITLE>'; bloginfo('name'); wp_title(); echo'</TITLE>';
} else if ( is_404() ) {
      echo '<TITLE>'; bloginfo('name'); echo ' - 404 Error'; echo '</TITLE>';
} else { echo' <TITLE>'; the_title(); echo ' | '; bloginfo('name'); echo '</TITLE>'; 
} 
?>
