How to add meta noindex on certain vanilla category?
Is there any addon to make it easier adding meta noindex on one or more vanilla category?

Hi, do you find a way to do that? I want to noindex an entire category too

You would need a small plugin for that. It should also be possible with a custom theme, but I think something like that belongs to a plugin and not a theme...

   public function base_render_before($sender, $args) {
       if (!property_exists($sender, 'CategoryID')) {
           return;
       }
       if (!in_array($sender->CategoryID, [1,3,5])) {
           return;
       }

       $sender->Head->addTag(
           'meta',
           [
               'name' => 'robots',
               'content' => 'noindex, follow'
           ]
       );
    }

This method needs to be inside of your plugin class. It checks if the current page belongs to one and only one category (like a discussion would) and afterwards checks if this category is in a list. You would have to customize that list or replace it with a direct comparison "$sender->CategoryID != 7"

The last piece of code adds the noindex meta tag.

You can pimp it up, by making the list of CategoryIDs configurable and upload it 👍️

Or you can duplicate/edit your theme template

<head>
  ...
  {if $Category.Name == 'this' || $Category.Name == 'that'}
   <META NAME="ROBOTS" CONTENT="NOINDEX, NOFOLLOW">
  {/if}
  ...
</head>
