In my opinion, Black hat and submission in low PR sites.

Avoid black hat seo, google don't like black hat seo. it's harful for site's keywords ranking.

Directory Submission are failed now a day.

I think all black hat SEO techniques are not useful after the new penguin Google update, as we all know black hat SEO may sound so attractive for a quick rush of traffic but it will get you in trouble. Following black hat SEO techniques may offer you instant result but later you will definitely get punished by search engines. So make sure that you do not employee any of the black hat SEO techniques for promoting your website.
