12 tips to boost brand awareness and attract social influencers

expert panel

Business experts discuss their media communication strategies. If you're a rising brand in search of building relations with a high-profile figure on social media platforms, it may not be as difficult as you think to attract some initial attention if you approach these potential partners in the right manner. Instead of hoping that they'll possibly respond to your casual direct message, research who their official contact person is and write up a serious proposal.  But just like matrimony, it's all about the relationship and connectivity. It's an important business commitment to consider and neither party should ever take it lightly. Therefore, be honest about your intentions and see if it's a good match first before you (and the company) get involved. If you do your homework, be generous with your time, and make it less about, only you, in the end, it may end up being a tremendous win for all. Below, 12 Fast Company Executive Board members weigh in on the best approach to appeal to a social media influencer and get them on board as ambassadors to help promote what your business is offering.
