The success of a marketing campaign for a business depends on where their target audience is. For some businesses social media can be extremely effective and other businesses can see more success with email marketing. We generally recommend trying several different digital marketing strategies such as email marketing, SEO, Google AdWords marketing and social media marketing. Once you identify which marketing strategy is the most effective for your business you can adjust your spending to maximize your ROI.
