After working on some influencer identification product reviews and stories recently, I decided it might be useful to compile a list of influencer discovery tools for your use. If I’m missing any software platforms or services in this list, please drop a comment or send me an email and I will update as needed. Consider this an ever-growing resource and bookmark it or share with your networks. I promise to update it and annotate it as needed. This list is not (yet) comprehensive. Please help me build it.
