Traackr identifies social media influencers in a topic area by measuring an influencer's reach (size of online audience), relevance (contextual affinity to the topic area), and resonance (engagement of the influencer's audience with their content). Traackr used these factors to identify the top 50 recipe influencers and uncover their full online footprints and relevant posts about recipes. Recipe.com then invited these influencers to a webinar, with 24 responding positively.
