Welcome to the forums, aloksharmaseo.
Please do a search beforee posting a new question, as you'll often find it's been asked and answered before. There are already several threads discussing how to increase traffic.
I suggest you read the sticky threads at the top of this forum, and any other threads which interest you. These will provide you with a great deal of information. I would also recommend you download and read Google's Search Engine Optimization Starter Guide. After that, if you still have any specific questions, then please feel free to post again. Meanwhile, I am closing this thread, as your question is too general to attract any meaningful answers.
