Many webmasters never bother to promote their websites offline because unlike on the net where you don't have to spend any money to promote your website, to get good results when promoting your site offline, you have to be willing to spend some money.
While ads can be a good way to get some traffic, people read ads only once and they may or may not visit your site. If however they see your URL every day, their curiosity might probably prompt them to visit your site eventually. This is why if you can, you should spend a little money on promotional items: slap your URL on T-shirts, pens, coffe mugs, etc, hand them out to people and many of them will visit your site.
