Hi,
The content=”noarchive” implicitly means content=”index,follow,noarchive” – as long as there is no “noindex” there, the page is considered indexable, and the same is true for nofollow/follow.
So making this change won’t have any effect at all, except allowing cached results (removing noarchive will cause this).
If you still want to do it, you can add the following code to your theme’s functions.php file:
add_filter( 'wpseo_robots', 'mts_robots_meta_change' );
function mts_robots_meta_change( $robots ) {
return 'index,follow';
}
This will change the meta robots content for all the pages on your site.
By the way, Yoast’s support forum would be a more appropriate place to ask such questions: https://www.ads-software.com/support/plugin/wordpress-seo
Hope that helps.
