Sell Banners
1. Locate the space on your web pages where you will offer to place banners for advertisers. Banners are commonly sold in a number of standard sizes including 300x250, 250x250, 468x60, 728x90, 160x600 and 125x125.
2. Join an ad banner advertising service like AdBrite.com, BuySellAds.com or AdEngage.com. These companies serve banner ads for advertisers that can be placed on your website. Typically, publishers are paid by the number of ad impressions served.
3. Find the offers you want to advertise and place their banner ad code on your web pages. The ad service will maintain a record of each ad impression served and pay you on a regular basis.
Google AdSense
4. Join Google's AdSense program at https://www.google.com/adsense/. Google allows website owners to place AdSense pay-per-click ads on their websites and shares in the revenue generated by each click on the ads.
5. Determine the sizes of ad blocks you want to place on your web pages. AdSense provides a wide range of different ad block sizes for you to choose from.
6. Customize the colors and borders of the ad text to fit your website color scheme. Integrating your ads within your website will usually result in higher click-through-rates and generate more revenue.
7. Copy and paste the code provided by AdSense into your web pages. AdSense will determine the ads served by matching ads with the content of your pages.
Affiliate Marketing
8. Join an affiliate network like ClickBank.com, NeverBlue.com or ClickBooth.com. These companies offer a wide range of products and services for sale on an affiliate basis. For every sale generated by traffic from your website you will be paid a portion of the sale or a fee for generating a lead.
9. Identify the affiliate programs you wish to promote. Select programs that appeal to the demographics of your website visitors in order to maximize your revenue.
10. Place ads on your website. Most affiliate programs provide a selection of banner and text ads available for use by affiliates. Choose the ads that fit the ad space available on your website and that appeal to you.
11. Split-test the ads on your website. Rotate two ads in the same ad space and measure the response of each of the two ads. After you have received 30 clicks or more on each ad, you will have enough data to decide which ad converts better. Remove the other ad and run the winning ad full time.
