Social media is an essential marketing channel that allows businesses to communicate with customers, share content, and gain insights. Studies show that companies that blog regularly generate more leads than those that don't. Monitoring social media for just six hours per week can increase leads. Leading brands have established social media "command centers" to optimize their use of social media for marketing. Businesses can improve their marketing ROI through social media by acquiring customer knowledge, gaining competitive insights, monitoring influencers, and measuring the results of their social media efforts.
