Do Follow links are links that are and that can be crawled by search engines. No-Follow links are, of course links that won’t be crawled by search engines.

<a href="http://www.wpkube.com" rel="nofollow">WP kube</a>

Make blogroll links NoFollow

function no_follow( $links ) {
foreach($links as $link) {
$link->link_rel .= ' nofollow';
$link->link_rel = trim($link->link_rel);
}
return $links;
}
add_filter('get_bookmarks', 'no_follow');

Make Comment links Dofollow

function do_follow($string) {
$string = str_ireplace(' rel="nofollow"', '', $string);
return $string;
