ANSWER:
One of the major goal in social media campaign is AWARENESS.
Awareness is very important in marketing a product, as a proposed customer may not patronize a product he/she is not aware of. Since the company wants to increase it's sales, it will be important if the company increases it's awareness through social Media, which is a very cheap and fastest way to advertise a product.
As seen in the world today, about 90% of people living in a developed country has a social media account, and about 70 to 80% of people living in a developing country has a social media account, while 50 to 75% of people living in an undeveloped country has a social media account.
With this estimated proportion, it will be easy to reach almost everyone if the companies products is marketed using social media. This can be achieved by opening a social handle and a companies website for the company, which will make it easier for people to reach the company and know about it's products, without coming to the companies location. You can increase the awareness of the companies social medial handle, website, and products, by signing an agreement with some celebrities to market the companies products, along with it's social handle and website, through their social media handle, which always have millions of viewers.
