Add “Read More” permalink to the end of the_excerpt

Adding this snippet below into the functions.php file of your WordPress theme will add a “read more” permalink at the end of the_excerpt, pretty much like what the_content does.

function excerpt_readmore($more) {
    return '... <a href="'. get_permalink($post->ID) . '">' . 'Read More' . '</a>';
}
add_filter('excerpt_more', 'excerpt_readmore');
