my website dont get traffic & good ranking after using link building, article submission, then what can I do ???????
What do you mean by Linkbuilding? This question's answer should be clear to you and the people on DP first! What kind of efforts your have put for getting traffic and good ranking. As achieving both these things requires different approaches. Such as directory submission will not help you in getting traffic however it may help you get good ranking on SEs.
To get good traffic, use twitter for example and update regularly, giving your link to your articles etc. Also, StumbleUpon is brilliant if you want traffic
You need to try with different link building practices(white hat ofcourse)... let me know what have you implemented?
Just try to build traffic through a few different methods. You can implement emails, talk on forums that are related to yours and blogging as well. These will also benefit your SEO as well.
