Same page for startpage and archive?

Use the Taxonomy_Parameters in WordPress WP_Query like that:

$args = array(
    'posts_per_page' => 6, 
    'post__not_in'   => $do_not_duplicate,
    'tax_query' => array(
        'relation' => 'AND',
        array(
            'taxonomy' => 'category',
            'field'    => 'slug',
            'terms'    => 'art',
        ),
        array(
            'taxonomy' => 'country',
            'field'    => 'slug',
            'terms'    => 'france',
        ),
    ),
);
$myposts = get_posts($args);

you can add the “country” taxonomy to links as url parameters and get it when click the the like.
