How to Use AdSense Code on Multiple Websites

AdSense is a Google program for website publishers who want to earn advertising revenue on their websites. Once you have been approved for a Google AdSense account, you can use that account to publish ads on any of your business or personal websites, provided those sites adhere to Google AdSense terms and conditions. Although it's not mandatory, adding a Uniform Resource Locator (URL) Channel to your AdSense account for each website will make it easier to track your advertising revenue. You can also use Custom Channels to group your ads by design or location across multiple websites
