There's plenty of general information and advice in the FAQs at the top of each forum, including the SEO and Internet marketing forums. Please have a read through those, and you'll get lots of tips on what you can do to boost traffic.
If you've then got any specific questions, please feel free to come back and ask them. In the meantime, I'm closing this thread before it degenerates any further.
