I wanted to get the Yoast SEO generated data manually, see example code below

This data is being generated by Yoast and automatically add it inside the head tag .

I do not want to use wp_head(); because it also generates other scripts, styles and whatever plugin or code you have in your wordpress website.

I do not need all those codes. I only want to get the Yoast SEO generated code as shown above. any ideas how could i do that?

Answer 1

You can get the yoast meta in any page by get_post_meta() ,

get the meta values by following,

echo get_post_meta(get_the_ID(), '_yoast_wpseo_metadesc', true); 
echo get_post_meta(get_the_ID(), '_yoast_wpseo_title', true); 

Check the post_meta table to get all the values related to each page/post.

Answer 2

Use this below:

do_action( 'wpseo_head' );

It will print all SEO header in your head. No need to add through post meta.

Answer 3

It's four years later, so things have changed here. The data can now be retrieved via API in a structured way: Example:

echo YoastSEO()->meta->for_current_page()->description;

See: https://developer.yoast.com/customization/apis/surfaces-api/

Also via REST a access is possible: https://developer.yoast.com/customization/apis/rest-api

May that sometimes helps. To get the meta at all (unstruktured), the both other ways are sufficient.
