Weird Title Glitch

It noticed this when creating conditional page titles, this is the current code that ultimately worked, but at first when I had the elseif for archives above the elseif for categories it would title all my category pages as archives for some reason. Strange.

<title>
<?php
if ( is_single() ) { bloginfo('name'); echo ' - '; the_title();}
elseif ( is_category() ) { bloginfo('name'); echo ' - Categories';}
elseif ( is_page() ) { bloginfo('name'); echo ' - '; the_title();}
elseif ( is_archive() ) { bloginfo('name'); echo ' - Archives';}
else { bloginfo('name');}
?>
</title>
