Internet Marketing and Digital Marketing as far as I am concerned are inter changeable both have to do with promoting your business on the internet.
The question is, how it’s done? Which company is doing it for you? What exactly are they doing for you? Make sure these questions get answered to your satisfaction. After all you are the one paying the agency. One of the most important aspects in Digital Marketing is your expectations. They should be realistic. What does that mean exactly? You need to take the amount of money you are spending and see which results you receive in return from that spend. For example, if you spend $100 don’t expect to rank number one in Google after the first month. Depending on your location and competition it could take a lot longer than that.
