SEO Yoast Meta Description Issue

I have installed SEO Yoast and have used it to edit the ‘snippet’ / meta description on blog posts. However, this edited version of the snippet does not display on the Google search results.

I have read that I might need to add or modify a command to the header.php to reference the meta description from Yoast. How do I do that?

Please advise.

Hello there,

It may take time to see the changes on the search result. Try again tomorrow.

I thought you don’t have to manually edit the header.php file. Because the Yoast SEO plugin automatically does that via hook.
