You can make money from your website even if you don't sell hard goods or soft products. Earn money through advertising, acting as an affiliate or even selling other people's products.
Do you sell hard (coffee cups, t-shirts, lighting fixtures) or soft products (eBooks, software, services)? You can set up a shopping cart or use paypal to sell your own products on-line.
Don't want the hassle of storing and selling your own product? Sell products manufactured by others via and have them drop-shipped directly from the manufacturer.
If you run a travel sight, you can sell adspace on your site to local restaurants, hotels, attractions, realtors, etc. But you'll have to prove that you a high traffic site where they are going to get high visibility.
One of the easiest to implement. You don't have to go looking for advertisers, Google brings them to you and the advertisers are matched to the unique content of each of your pages. See Google Adsense for more information on how to set-up this revenue channel. Again, without large amounts of traffic, you won't make more than pennies with Google Adsense.
I have no doubt that you will be shocked when I let you in on the next secret. You won't believe me until you actually go out and do some clicking yourself on the internet. But suspend your disbelief for a moment and humor me.
Many companies will pay you to send buyers to them through affiliate partnerships.
For instance, follow this link to Rockler.com and scroll down to the bottom of their website's homepage. Do you see the link for affiliates.

You can sign up with Rockler as an affiliate and for every visitor to their site that requests their free catalog, they will send you a small fee. You will be given special code that you have to use within the link so Rockler can track where the visitor came from, but that's it, they do the rest and you get a check, usually when your commissions hit $100.
There are thousands of companies that offer "affiliate" commissions. Find partnerships where there is a synergy between your website and those that you are recommending. For instance, if you have a woodworking website, Rockler would be a natural link out for your users. If you were a realtor, a mortgage company or bank might make a perfect affiliate. Keep your eyes open, affiliate opportunities are everywhere. Use them only to help your visitors and only to recommend website and products that you feel good about.
