Generally, there are a number of reasons why low-cost marketing plans are efficient in small businesses. First, because small businesses typically don't have the same resources as larger businesses, they need to be more creative and strategic in order to get their message out there. Low-cost marketing plans allow them to do just that.
Second, because small businesses are always competing against larger businesses, they need to find ways to stand out from the crowd. Low-cost marketing plans help them do that by enabling them to target a specific audience and create a unique branding strategy. Finally, because small businesses are growing at a much faster rate than large businesses, they need to constantly update their marketing strategies in order to keep up.
