1. Go to the Google AdSense website (see Resources) to sign up for an account. Enter your Web site URL and your site's language. Select whether you want a business or individual account. Enter your contact information, such as your address and phone number. Agree to the terms and conditions and click 'Submit'. Once you have submitted your application and verified your email address, it will usually take 2-3 days for Google to approve your application, but it can sometimes take as long as a week.
2. Login to Google AdSense after your application has been approved. Click 'Account Setup'. Select either the AdSense for Content product or the AdSense for Search product. AdSense for Content will place ads on your site. AdSense for Search will place a search box on your site.
3. Choose the format, color and font for the AdSense ad product. Click 'Continue'. Choose your search type, selected sites and optional keywords for the AdSense search product. Click 'Continue' and answer the questions until you get to the last page.
4. Click 'Submit and Get Code'. On the next page, the AdSense code will appear as a long block of HTML code. Copy it by holding down the mouse button and dragging the mouse over the code to highlight it. Right-click on 'Copy'.
5. Go to your Web site's template and paste the code between the body tags of the template's HTML.
