Data-driven decision making is key to a successful advertising campaign. Advertising campaigns are expensive. Therefore, companies need to maximize every cent that goes into them. There are different forms of advertising campaigns and businesses must understand which one is the most effective. When a company is designing a campaign, they must keep three things in mind. First, the goal, what are you trying to accomplish. Second, the audience, who are you targeting. Third, the budget, how much are you spending to get the message across. Once you have deciphered these things, it will be easier to determine which forms of advertising works best for your campaign.
