Banners do work in the right context, targeting the right audience. Banners on endemic developer sites, such as the Developer Media sites, work because they are shown in the proper context, on sites where developers are coming specifically to look for developer solutions.
The most successful campaigns run static banners, with product features, discussing the problems the advertiser’s solution solves. Free trials, demos, or “learn more” offers work best. Developers want to get their hands on the tools and test drive the solutions themselves. We recommend staying away from marketing hyperbole such as “fastest,” “best,” and “most scalable.” These tactics do not resonate well with developers.
