In every email you send, every newsgroup or forum posting you make, be sure to have a signature file at the end of each message. You will be surprised just how much traffic you can build if you post in the right places and provide useful messages and not just blatent advertisements. It goes without saying almost. You must register your pages on search engines. There are all sorts of tools available to help you, but many of them will cost you money.
Search engines are important, and worth getting right.
If you really don't know what you are doing then you might want to pay someone to do it for you, but I would suggest that the better option is to learn how. FFA Link Pages. Whilst that is partly true, if you post with a very strong headline, and use a multi-submitter, then you will be surprised how a few minutes work can generate a reasonable supply of visitors. I still post to FFA pages - it takes just a couple of minutes to cut and paste my headline and other details. If you have a speciality line of goods and use a content filled site more than a direct sales two or three page type arrangement, then a web ring could work for you.
