A great way of making money online is to write articles on topics that interest you. The way it works is you write a article on the topic of your choice and at the bottom in the author biography you put a link to your website or blog.
Let's use golf as an example. Let's say you have a website about golf. On this website you have offers on golf products or Google AdSense ads advertising golf products.
So you research or use your own knowledge on golf clubs. You write a nice informative article about different types of clubs. You want to let the reader know everything you can about the clubs your writing about.
The person reading your article is going to learn everything about the clubs you decided to write about. Once they learn about the clubs they can decide if they want to purchase the clubs you are writing about.
So how does this translate into money in your pocket?
1) You have targeted traffic. You know that the person who clicked on your article is interested in golf clubs. So odds are that they are thinking of buying some.
2) You are pre-selling the clubs you are writing about. The reader will know all the benefits of owning the types of clubs your writing about.
3) After reading your article they will see your author biography at the bottom of your article. In the biography is your link to your website where they will have the opportunity to purchase those clubs.
Now you can write about any type of product you want. Just make sure the article is well written and gives the reader some great content. If you do this you should be making money online in no time.
