Google AdSense review

AdSense is run by Google and serves websites with relevant ads. Publishers can join for free and can show automatic text, image, video, and rich media adverts that are targeted to site content and audience. These adverts are administered, sorted, and maintained by Google. You can earn money from AdSense on a per-click and/or per-thousand-impressions basis.

Google uses its search technology to serve ads based on website content, the user's geographical location, and other factors.

There is also AdSense for mobile. This allows publishers to generate earnings from their mobile websites using targeted Google advertisements.
