• It can be difficult to determine which influencers to accept and how to execute a meaningful collaboration.
• Be choosy. Follower numbers don’t always tell the full story. Find out, if these followers are the target demographic you’re interest in reaching. Ideally the influencer does have a loyal fan base across channels (blog, YouTube etc.).
• Outline clear expectations before you host an influencer (e.g. how many posts you want to see each day on Instagram, Snapchat, Facebook, Twitter). Request the rights to photos and videos.
• Have a plan to measure success of a collaboration.
• Choose an influencer who fits your brand and has traveled to similar places.
• Amplify the influencer’s message (e.g. by retweeting, linking to posts, re-gramming images, sharing information across all your social media channels).
