Influencer marketing is a type of social media marketing involving endorsements of products and brands from inluencers. An influencer is a person or organization who has a significant impact in the marketplace with allot of experience and knowledge or social influence in their field of trade.
Influencer marketing uses key leaders or influencers to drive a brands message to the target market such as Facebook, Twitter, Instagram, Snapchat etc. Influencers usually have a big audience and a big following which helps the brand get it’s message across. Influencer marketing has been on going for a very long time for example Oprah Winfrey would be a influencer all she would need to do is recommend a book in the country and bookmakers across the country would know running out of copies would be a problem for them.
Another Example of an influencer would be Jada Pinkett smith advertising Pantene’s brands message to her 1.23million twitter followers and the message would come from the brand Pantene.

The market place would usually listen to influencers as they usually have a solid following, they also play the role of bloggers and journalists etc and they are looked to as role-models.
Businesses have a lot to gain from using influencers with their marketing to gain as much brand exposure as humanly possible and because the influencers come from different backgrounds a niche can also be established with the business and it’s products it wishes to promote. Influencers do not have to be celebrities they just need to have a solid following/fan base.
