Adding a H1 Tag to Post Tags automatically, but hide the tag? (Same for Category)

Question

So to increase my SEO score I require all tag pages to have a H1 title, for example website.com/tags/taghere would need the title: <h1>TagHere</h1> or simply <h1>taghere</h1>

I can go through each tag manually and add them but this would beyond tiresome to do for 1000+ tags, we're running the Avada theme and I can't see any option anywhere to do this automatically.

Is there a way I can create a function for the functions.php to do it automatically?

Essentially I want to do the same as what you see:

Hopefully someone can advise a solution, this would then also be usable for categories too.

Answer 1

1. Create custom action in function.php, which checks current page type (if it's category or tag page).
   

   function hidden_term_name_action() {
   
       if( is_category() || is_tag() ){
   
           $term_id = get_queried_object_id();
           $term = get_term($term_id);
           if($term){
               echo sprintf('<h1 style="display:none;">%s</h1>', esc_attr($term->name));
           }
       }
   
   }
   
   add_action('hidden_term_name', 'hidden_term_name_action');
   

2. Paste this code in header.php, which fires this action and pastes term title inside hidden h1 tag.
   

   <?php do_action('hidden_term_name'); ?>
   

P.S. Not tested, but give it a try.
