These questions are vital because it will determine the frequency that your advertisement will need to run. So, for example, if your campaign is only lasting for two weeks, you’ll want your ad displayed as much as people so that people will notice it and have a sense of urgency to buy into whatever you’re marketing. If your campaign is lasting for a few months, on the other hand, you won’t want to overwhelm your audience with the same ad over and over and over again until they eventually block the annoying ad. We need to be respectful towards our audience.
