1. Copy the code for your AdSense unit into a text editor such as Notepad. If you do not have an AdSense unit yet, go to the AdSense website, log in and click 'My Ads' at the top of the page to create a new unit.
2. Place the cursor at the beginning of the AdSense code, then press Enter to create a new blank line above the code.
3. Type '
' or '
' and press Enter. Type 'right' after 'float' to position the AdSense unit to the right of your website's text, or 'left' to position it to the left. The number after 'margin-left' or 'margin-right' indicates the number of empty pixels that will be placed between the AdSense unit and the text of your website. Modify the number if desired.
4. Move the cursor to the first blank line after the end of the AdSense code.
5. Type '
' in the blank line.
6. Copy all of the text in the text editor, and place the new block of code into the source code for your website to begin displaying the AdSense unit.
