This is one of the fastest growing and most effective ways to get your businesses message across. Social media can be used to engage with the massive amount of daily users on multiple platforms (Facebook, twitter etc.). Large follower bases can be established, which gives an audience that can be marketed to.
It is also one of the cost effective methods of marketing, usually only costing when an advert is actually paid for. Whether it is through paid advertising or posting regular updates, social media has no shortage of options when it comes to marketing.
