There are many ways. Assume you just purchased a store front on main street. How are you going to get business? You advertise! So then you look at the different forms of advertising. Same thing on the internet. There are so many books out there that anyone can get totally bogged down in information. Concentrate on one item, whether it's Google Ads, free advertising on various sites, article placements, banner ads, web 2.0, etc. Look at costs, look at your budget, make a decision. Try different things. Some work but some create traffic. Just don't quit.
