How to display the title and meta etc. in Google properly

So I’m creating my own WordPress templates, but I have one small problem. I’ve edited my snippets as how I want them to, yet they don’t show up as how I’ve edited them in Google.

This is what I’ve added in my head:
<title><?php the_title();?></title>
<meta name=”description” content=”<?php bloginfo(‘description’); ?>” />

Somehow, the snippets that I’ve added aren’t being displayed in Google.
How can I make that happen? Is there a setting that needs to be changed or is there a php code for Yoast?

Thanks in advance.
