Change single post title in wordpress

Basically, WordPress outputs the blog’s post title as “Blog Title >> Blog Archive >> Blog Post Title”.

For example :

Myo Kyaw Htun . com >> Blog Archive >> Hello World !

But most of the bloggers , they want to get the highest rank in Search Engine. This following code will boost in search engine ranking of your blog. So, if you want to change the way that I made, fine the <title> tag in header.php located in your default template. (Presentation >> Theme Editor). Replace the following codes between <title> and </title> tag.

<?php if ( is_single() ) { wp_title(' '); ?> » Blog Archive - <?php } ?><?php bloginfo('name'); ?>

So it will look something like that :

Hello World ! » Blog Archive » Myo Kyaw Htun . com
