This depends on the domain, but in most cases the easiest and most efficient way to advertise is to contact the publisher directly or by using programmatic advertising. You should contact your agency or in-house teams to discuss setting up your campaigns. In case you are buying programmatically, please ensure you consider setting up an effective Supply Path Optimisation strategy to maximise the advertising spend that is received by the publisher. For more information about this, please contact our partner Jounce Media. We aim to create easy-to-target line items in major Demand Side Platforms (DSPs) that provide a single point of access through a deal ID targeting all the domains on the inclusion lists. This is currently work in progress.
