Quite simply, an influencer is someone who can influence others. In influencer marketing, that influential person collaborates with a brand to promote something. Influencer marketing puts your brand in front of a captive audience that already loves and respects the messenger.Influencers already get the undivided attention of your audience. With influencer marketing, that attention becomes yours.Your customers all have someone they respect, look up to, and idolize. Plus, unlike an ad in a magazine, you can see exactly how many people saw it, liked it, and double-tapped it.
