I love mountain biking and doing jumps, I live next to the trails and I am always on them learning new tricks and getting better and meeting new people. I am a good rider, better than the average mountain biker, if you sponsor me I will be out on the trails supporting your brand and products by using them and showing them to people, and promoting them on social media, I can also give feedback on your products. And your products will look good when I place good in races using them, thank you for taking the time to read this.

How do you measure influencer marketing ROI when half the numbers social media gives you are vanity metrics? It is the question brands ask us most, and it came up again when I joined Massimo Marinelli on the Berkida Ventures Podcast. After more than ten years and thousands of brand deals with athletes and creators at OpenSponsorship, here is how we think about it, and the framework we use with our clients.
