Certain networks tend to focus on marketing aimed at making an immediate sale. They offer access to more homogeneous pools of direct marketing-oriented sites, serve ads that usually contain a "buy now" or other actionable option and are equipped to more smoothly handle the logistics of credit card and other online transactions. Their charges are typically CPC or CPA, reflecting their heavily performance-based approach and minimal (if any) fees.

Examples include:
Ad Pepper Media
Azoogle
ValueClick Media/Fastclick
Vizi Media
