Empty pages

To add a meta noindex, nofollow to an empty page you have to inform the module with the smarty tag {set_empty_page_meta}
All the page where this tag is present will have a noindex meta.
For example if you use a loop product in your category page you can add this tag in your elseloop like this :

    {ifloop rel="product_list"}
        <div class="row">
            {loop type="product" name="product_list" category=$category_id}
                <p>{$TITLE}
            {/loop}
        </div>
    {/ifloop}
    {elseloop rel="product_list"}
        {set_empty_page_meta}
    {/elseloop}

With this, all categories page without products will not be indexed by robots.

Pagination meta link

To add a <link rel="prev" href="http://url_of_prev_page> or <link rel="next" href="http://url_of_next_page> in your head you just have to add the smarty tag with the good url :
{set_prev_page_meta_link url={$url}} for the prev link
{set_next_page_meta_link url={$url}} for the next link
