Yoast SEO Meta descriptions: API documentation

To change the meta description tag that Yoast SEO generated programmatically, you can use the wpseo_metadesc filter.

Change the meta description tag

For example, the following code would change the meta description on a page with ID 12345:

* Filters the description.
* @param string $description The current page's generated meta description.
* @return string The filtered meta description.
function prefix_filter_description_example( $description ) {
if ( is_page( 12345 ) ) {
$description = 'My custom custom meta description';
return $description;
add_filter( 'wpseo_metadesc', 'prefix_filter_description_example' );
