Ezoic improves ad engagement whilst balancing that against user experience.
Ad targeting isn't the same as Ad location. The Ezoic system tests lots of different ad positions and sizes on a page. Each layout test gets tracked for UX (user experience metrics - time on site, page views per visitor and bounce rate) and also for the income per thousand visitors (epmv). The layouts with the best advertising engagement that balances income and UX get more traffic..
