AdSense

AdSense is a program run by Google that enables publishers to earn revenue by displaying targeted advertisements on their websites, apps, and other digital properties. Advertisers bid to display ads through Google Ads, and AdSense serves ads that are relevant to the site’s content and visitors using automatic targeting and auctions.

Publishers apply to join AdSense; after approval, they insert a small code snippet on their pages that places ads in designated areas. Ads are selected and served automatically, and earnings come from clicks (cost per click) or impressions (cost per thousand impressions). Historically, publishers receive about 68% of the revenue from ad auctions, with Google retaining the rest, though the exact split can vary by market and agreement. Payments are issued monthly once earnings reach the local threshold, typically around $100, and can be received through multiple payment methods.

Ad formats supported by AdSense include text, image, rich media, and responsive display ads that adapt to screen size and device. Ad placement, page load speed, and compliance with program policies influence both performance and user experience. Publishers are expected to maintain quality content and avoid practices that could trigger invalid traffic or policy violations, such as encouraging clicks or placing ads on disallowed content.

Policy and scope: AdSense enforces content guidelines and prohibits copyright violations, violent or adult material where not permitted, and invalid traffic. The program has evolved to include various products, such as AdSense for content, AdSense for search, and integrations with broader Google monetization tools, including devices and YouTube’s partner ecosystem, where applicable.
