Google AdSense is a program that allows website publishers to earn money by displaying targeted Google ads on their web pages. Publishers sign up and place AdSense code on their sites to display text, banner, video, or search ads. Advertisers bid in a real-time auction to display their ads, and publishers earn money based on the number of clicks or impressions. Factors like traffic volume, content quality, and click-through rates affect revenue. AdSense provides publishers access to advertisers without direct partnerships and analytics to optimize earnings. It differs from Google AdWords, which is for advertisers to create ads, while AdSense monetizes existing publisher traffic. Other monetization alternatives include Facebook ads,
