Do we really need to know something about AdWords to answer this question? At least even AdWords exam can be funny.

Choosing the right bid is essential for your campaigns. Often finding the optimal bid for your specific business is a long process which requires multiple tests. In other words, there’s no single recommended bid amount that works perfectly for everyone.
