Yes, it is possible, but you will need to create a module to do it yourself, because there are no modules in the Orchard gallery that process ads. There are several easy ways to do this without adding any code; it really depends on what you need to do to place your ads.
If you just need to drop some html tags to specific pages, you can do this through the user interface of the Orchard panel in at least several different ways. The easiest way would be through Widgets. Dashboard-> widgets-> Sidebar-> Add-> HtmlWidget. Drag and drop the HTML tags into the wysiwyg editor and configure the rules so that this widget publishes the desired zone and pages. Please note that the above instructions should be published in the “sidebar”, but you can replace this for any zone you want. You can use rules / levels to customize the URL where your ads appear.
