Well the best way to explain more about this would to guide you here: https://moz.com/blog/google-link-command-busting-the-myths it's already from 2009! but I'd say still relevant. These link commands are pretty useless these days. I'd set up the Google Webmaster Tools the right way to make sure that the data on your external links is up to date.

I found that habkorea.com which have no page for the keyword of 'korea private tour' , but the keyword is rank 1 page. i try to find why, then i came to know, internal link which google display on search result, that is the reason that make 'korea private tour' on 1st page. i want to know why it happens,
