It is impossible to answer such a question because so much of getting an ad live relies on the poster. We have over 300 machines with clients successfully posting in all sections. However, VIPN is only a tool, it is not magic and will not compensate for poor posting practices.
Asking what is the live ratio, that is like asking, if you give me the best hammer in the world, what is my chance for success for building a house?
Depends on the builder, vipn is a tool. a computer doesn't get ads live, a poster does, however, vipn is the best tool on the market for assisting you.
