1. Decide what your business is going to be about. Two points here. Pick something you already know something about and hopefully enjoy, and then refine it to a smaller area of specialty. Instead of "outdoors", think "hiking". Instead of hiking, think "hiking boots". If you know what you are talking about and enjoy the subject, it will be easier to talk to people (online or in person) and transmit your message of enjoyment to them. Also, building a business takes time. If you are concentrating on "money" and the money doesn't show up right away, you will lose interest. If you love hiking and are enjoying putting up your website about hiking, talking to people about hiking, and checking into new hiking products, you will remain interested in your business through the build up/learning period when no money is coming in.
2. Find a company to host your site for free. Shop around and compare services. At this point, since you hardly know anything, you might want a web hosting service that provides some sort of site builder where you fill in blank areas and the service creates the page. Later, when you know more and get your own domain name or names, maybe you will know a bit more about website design and will be able to do it yourself. For now, however, you need all the help you can get.
3. Sign up as an affiliate with companies that sell products related to your interest. For example, you can become an affiliate of REI or Backcountry, through Commission Junction. These two companies sell hiking boots and other outdoors goods. You could also offer goods or services indirectly related to your site. Staying with the hiking boot scenario, you might offer physical training courses or even vacation packages for hikers.
4. Create your site. Rest assured, your first attempt will not be your best, nor will your 87th probably. That's okay. It's all a learning experience. What to put on you site? Not sales stuff. Not info about how great these boots are. Tell your visitors how to pick a boot. Explain how to care for their boots. Teach them about hiking safety or how to find a campsite for the night. Tell them where they can find weather reports and a list of hiking trails. In among the real, genuine content, sprinkle a few (got it...FEW?) links to your products. If you don't know what to say, visit some sites that say it well and then say it in your own words.
5. Go to Selfpromotion.com. You will need to promote your site to search engines and directories anyway. You can do that for free and in depth at SelfPromotion.com. However, if you look around the site, you will find a treasure trove of information about such silly subjects as search engine optimization. So pick up a free education while you're there. The webmaster over there accepts donations, and, now that he has helped me get my internet business off the ground for free, he gets liberal donations from me every year.
