Yoast SEO: Surfaces API |
Surfaces API |
Retrieve metadata from a post or URL, seamlessly. |
In Yoast SEO 14.0 we introduced a formal way of integrating Yoast SEO into your code. We've added what's called a surface, called YoastSEO()
. This surface gives easy access to lots of the features Yoast SEO has to offer.
All of the SEO data for the current page can be easily accessed through our surface.
For example, this code provides the page's title as a variable:
$title = YoastSEO()->meta->for_current_page()->title;
This code immediately outputs the page's meta description:
echo YoastSEO()->meta->for_current_page()->description;
This code outputs the estimated reading time for the current page.
echo (string) YoastSEO()->meta->for_current_page()->estimated_reading_time_minutes, " minutes";
The current_page
surface exposes every bit of data we have on the current page, which all work in the same way; it's a long list:

Getting data for any page works in almost exactly the same way as getting data for the current page. You just need to provide an ID, or a URL.
E.g., get the canonical URL value for a post with an ID of 2.
YoastSEO()->meta->for_post( 2 )->canonical;
E.g., get the title of a page with a URL of https://www.example.com/example-page/
:
YoastSEO()->meta->for_url( 'https://www.example.com/example-page/' )->title;
NOTE: If a URL doesn't exist in our Indexables table, then this method will return false
.
Sometimes you need more than just the raw SEO data of a page. For instance, you need to know whether the current post type should be indexable at all. Well, our post_type
helper can help with that:
YoastSEO()->helpers->post_type->is_indexable( get_post_type() );
This will return a simple boolean
.
If you want a list of indexable post types, you should use:
$public_post_types = YoastSEO()->helpers->post_type->get_public_post_types();
The same works for taxonomies:
YoastSEO()->helpers->taxonomy->is_indexable( 'category' );
There are quite a few of these helpers, and not all of them may be equally useful to you. But do have a look around in your IDE and see which ones we have to offer, this too is a rather large list!
