Google's ubiquitous AdSense ads are already heavily automated by their nature (they're targeted based on a look at a site's content), but it's taking that hands-off approach one step further. The search firm has officially launched Auto Ads, a system that uses machine learning to not only determine the types of ads you see, but how they're placed. The AI technology will decide how many ads are appropriate for a page and where to put them. Advertisers have to give up control, but Google has bet that they won't mind the results. A long beta test saw publishers rake in an average of 10 percent more revenue.
