you can add rel=”novbseo” tag to these links to exclude them from being processed by vBSEO:
<a rel=”novbseo” href=”http://news.yahoo.com” rel=”external nofollow”>
You should also manually enable VBSEO_ALLOW_REL_NOVBSEO option in config_vbseo.php file:
PHP Code:
define('VBSEO_ALLOW_REL_NOVBSEO', 1);
