Publishers offering "Between Content Ad" spots

A between-content ad appears in the natural break between pieces of content, such as the end of a Duolingo lesson, between chapters in Wattpad, or between editorial articles at AG Connect.

How it's sold: You book it with each publisher's sales team, and the example spots show the placement is usually sold as a package.
What it costs: Most publishers quote it on request, and per 1,000 impressions or a flat fee per month is the usual basis.
What you supply: You supply a banner or short branded unit that fits the publisher's template, plus a landing link.
Best for: It suits reaching people at a moment when they have just finished something and are about to choose what to do next.
Before you buy: Ask how many breaks a person sees per visit, because that decides how often your ad is shown to the same person.
