A page gets better ranking when the URL includes keywoard. URL’s with keywords in them yield higher clickthroughs than URL’s without. The SERP title and site summary is a matter as well.

We can do something little to enhance the WordPress title, so it wouldn’t be the same title on everypage.

<title>
<?php bloginfo(‘name’); ?>
<?php if(is_home()) { ?>
- <?php bloginfo(‘description’); ?>
<?php } ?>
<?php if(is_single()) { ?>
<?php } ?> <?php wp_title(); ?>
<?php if(is_404()) { ?>
- 404 Error! Page Not Found
<?php } ?>
<?php if(is_search()) { ?>
- Search Results for: <?php echo wp_specialchars($s, 1); ?>
<?php } ?>
</title>
