The cost of social media advertising can vary depending on several factors, including the platform you use, the scale of your campaign, the size and geographic direction of your target audience, and the competition in your market segment. In general, small to medium-sized enterprises can start with smaller budgets and adjust based on performance. Facebook and Instagram, for example, offer the possibility to set daily or total budgets, making it easier to control costs. A small daily budget can be anything from a few tens to several hundreds of dollars per day, depending on the objectives and desired reach.
