Digital marketing is cost-effective in that you can deliver your message directly to your ideal audience. Consider that traditional marketing casts a wide net across the general public. In contrast, digital marketing takes a targeted approach and engages the consumer with the right message at the right time. You can measure digital marketing efforts and the costs involved quite easily and mitigate unnecessary spending. This is far more difficult with traditional marketing campaigns. What's more, the costs involved with hiring a digital marketing agency are dependent on the scope of the project.
