Here are some tips on doing directory submissions:

• Find directory that have high PageRank.
• Find directory that gave you link. Check their source code. It should not contains “nofollow”tag.
• Use keyword on the link that is pointing to your website.
• If the directory has high PageRank, consider paying fee if you have the budget to get yourwebsite on their featured websites list. You will have instant backlink from high PageRank toyour website.
