Hello dear members,

These days I am in lot of panic. I am working in a Web Hosting company and i need to draw 500 visits to my site per day. I can't use any unethical method as daily performance is monitor by Google analytics. I had gone to every traffic method like Blog commenting, forum posting with signature, article submissions, social bookmarking, Post Guest post in blogs .

But my daily traffic is not more than 50 visits. Now I am bit demoralize. i would really appreciate some decent feedback in this critical situation.
Actually i am a SEO guy and my experience is limited to keyword ranking and never work for huge traffic . It seems too much tough for me.

Thanks a lot.
