Dont' want to index default Wordpress author page to search engines and Google?
Redirect the author page from your theme to the homepage easily with this function.
add_action('template_redirect', 'my_custom_disable_author_page');
function my_custom_disable_author_page() {
global $wp_query;
if ( is_author() ) {
// Redirect to homepage, set status to 301 permenant redirect.
// Function defaults to 302 temporary redirect.
wp_redirect(get_option('home'), 301);
exit;
}
}
Place this code to your theme functions.php file in the theme editor.
This works with Wordpress version 5.7.2 at least when I tried last time.
