Experts expect online sales in the United States to increase from $445 billion in 2017 to over $600 billion in 2020 and over $1 trillion by 2027. Taking these statistics into consideration, it is vital for marketers to use online tools such as social media and digital advertising, both on website and mobile device applications, and internet forums.
