There are many different ways to get an influencer to market you. You could have them feature one of your products or services. You could create a piece of content for them to publish for you. One extremely easy technique is to interview the influencer or have them interview you. Even the simple mentioning of your name on social media can gain you many new followers.
The first step is to decide what you want to achieve and identify influencers that can help you do that. Choose influencers that have a great deal of reach and that are relevant to your business; in other words, they have the kind of audience you want. Once you've identified some good prospects and narrowed them down to a manageable number, you should start connecting with your influencers and figuring out what value you can offer them.
Influencer marketing is powerful because it's like a referral from a trusted friend. The only difference is that this trusted friend has thousands of fans and followers who are hungry for what you have to offer.
