If you want to get the word out about your new product or service, social media will be your best friend. Social media can reach the biggest audience in the shortest amount of time and for the lowest cost. This is why social media marketing has become so popular as both a personal way to connect with friends and family, but also for companies to expand their customer base.

For example, most social networks that have millions of users are free to those users because they place ads on the page. These ads are seen by those millions, and they are cheap to design and place. If just one in a million make a purchase based on that ad, it pays for itself. Since more than one out of a million will buy based on an ad, you can expect high returns for using such an ad.
