Affiliate Programs
Another popular way to generate income from your weblog is through signing on with an affiliate program. Here's how they work. A company lets a website owner place a link or button on your site promoting the company's product. When one of your site visitors clicks on the link or button, the visitor is taken to a landing page to be induced to buy something. If the visitor buys something, you get a commission from the company. Sometimes the commissions are for leads, but most often they are for completed sales.The most popular Affiliate program in the blogosphere is Amazon's associate program. If you are an Amazon associate (www.affiliate-program.amazon.com), when you place a link to a book on Amazon from your site and someone clicks through that link and buys the book, you get a commission.

Advertising:
In addition to Google and various affiliate programs you can also take advertising directly from advertisers for your site. Tom Hespos outlines the steps in Yes, Blogs Are a Great Advertising Environment. One company that operates as a network of bloggers that accept advertising is Blogads. Blogads will take a very reasonable 30% commission of ads it places on your blog. To host BlogAds on your site you need to be invited by someone already part of the BlogAd network.

Affiliate

The first step you need to take to learn how to make money affiliate marketing is to go to an online marketplace, such as Clickbank.com, and sign up for free to become an affiliate. You will make up a nickname, this nickname is how all your sales and commissions will be tracked. Clickbank will track all your sales and send out a commission check to you.

Once you’ve registered you will need to find products to promote. All the products at Clickbank are digital: ebooks, software, audio, etc. These can all be downloaded instantly once a sale is made. All this is done automatically through the replicated website you will get for each product that you sign up to promote.

To make money affiliate marketing is really quite easy when you get going. Commissions run between 50-75% of the sale price of the product. So, depending on how much the product you are promoting sells for, you could make quite a bit of money with just one sale a day.
