Hey I'm trying to edit the php code so I can input more information about my site title. Here's my code. I not sure what part of it to change. Any help?

In my header php. file I have this code.

<?php echo ($title = wp_title('–', false, 'right')) ? $title : ''; ?><?php echo ($description = get_bloginfo('description')) ? $description : bloginfo('name'); ?>
</title>

What part of this code do I change to display a proper site title for when people google search my site? Thanks.

If you will break the template the other pages on your site will have same title.
Better use All in One SEO Pack plugin for wordpress to change page title as you like.

If you still want to break it then just change this:

PHP Code:

<?php echo ($title = wp_title('–', false, 'right')) ? $title : ''; ?>

to

PHP Code:

<?php echo ($title = "Your Title here"; ?>
