Depends on your needs, if you have several ppc accounts that you are managing and running ads in, it becomes a real hassle to maintain everything. Then yes it would be worth it to use some sort of aggregation tracking service like tracking202 pro that puts it all into one interface. But if your only doing one campaign under $100/day or something small at the moment, its probably not worth the upgrade just yet. It's really designed for affiliates who are managing lots of accounts, and those who need more automated and time saving tools.
