AdButler has been in the ad serving business for over 14 years now. It boasts an impressive list of clients that use their hosted service including Microsoft, MTV, IBM, Hewlett-Packard, and Allstate. They have extremely fast ad delivery and can handle custom ads of all formats. Their pricing model is a little high than some of their other competition, but they do offer some nice features.
AdButler supports all standard banner sizes, Flash, CSS, pop-ups, text ads, videos, interstitials, as well as complicated script ads. Text ad blocks are also fully supported. They also offer a no-questions-asked 30-day trial. If you’re not fully satisfied at the end of the trial, they will give you a prompt refund. They also offer technical support. AdButler does not have its own ad exchange to help you sell your unsold ad space inventory.
AdButler is a good choice for both small and large publishers. Small publishers can take advantage of the scalability this ad delivery platform offers. Make sure you add this to your list of hosted services to try.
