Hello,
Directories are not dead, but which directory to get backlink!

Priorities have changed now! Not to harm your site, do not make hasty steps! Very easy to get banned! Find SEO - Freelancer, carefully read the answer me about his work! Or just buy backlinks!

There are number online directories which gives back links. Recently i saw addyou(dot)org. Its quite good and very popular. You can add your business free there.

Hi, I have visited those site. Yes it is working but PR is low.

Make your friend google and find every thing from there.
