Some people say that having a post title which has link to itself is not good from SEO perspective. If you concur with this statement, here’s how to remove the link from the post title only.
1. Login to your self-hosted WordPress blog -> Appearance -> Editor
2. Click Single.php and find this code:
<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a>
3. Delete and replace it with this code:
<?php the_title(); ?>
4. Click Update File. Done.
