You're assuming AdGrok is just a frontend to Adwords. I think their platform is much more than that: besides the prettier/easier interface, I imagine its core is based on campaign optimization/management (through ML algorithms) and keyword generation, like kenshoo, clickfuel and clickable. If that's the case, then it is more than worth the 5% comission.
