Advertisements Module
Online publications need to make money, which is why Extra makes it easy to plug in advertisements directly into your category feed. You can add them manually using our Advertisement Module, or you can use Extra’s code module to input third party ad codes. In Extra, you are not restricted to placing ads in standard areas such as your Sidebar, Header or Footer. With the Extra Category Builder, you can place adds directly into your post feeds to improve engagement.
