the relationship between social media and the successful of a business

in my opinion social media plays the big role on promoting the business of a company. the social media also give a big opportunity to develop and spread the business. the power of word of mouth before can be apply on this era but using the social media. instagram is the best place to promote the product.customer can click on hashtag  and it will link on the original website. so it will easiest for customer to buy the product. if customer satisfied with the product or services, they will share the link or hashtag to other and automatically these product will spread widely. the seller need to speak in appropriate way to attract the customer. do not rude to customer when they ask the question because the customer always right.
