If we search for our brand name or any keywords that relate to our website, the first words to appear in the title shown in the Google result preview follow this format:
Brand Name: Title

I am using Yoast WordPress SEO, and each of the pages are not optimized the same as the above result.
Here's the WordPress code:
<title><?php wp_title('«', true, 'right'); ?> <?php bloginfo('name'); ?></title>
If we comment out the PHP code inside the title, the page itself has no title then.
I wanted to have the title first, followed by the brand name in the search results.
